;) I Can't wait to share my happiest moment in life so I'm not going to be wordy this time. Pictures speak a thousand words.

Finally lapped my Thermalright Ultra120 Extreme. The heatsink base was extremely CONVEX!
The lapping work took me more than 6 hours. Used 320x2, 400x2, 600x2, 1000, 1500 and 2000grid wet/dry 3M sandpapers. (more details and pics on this in the air cooled forum ;) )

NOTICE: I'm using Vista 64bit OS. So I can only open Speedfan 4.32 to get the core temp.
Coretemp 0.94/95 and Intel TAT aren't supported in Vista x64.

Before you start flaming about Speedfan's core temp inaccuracy, know that Speefan 4.32 assumes the max Tjunction is 85c instead of the actual 100c from the Quad.
You've to ADD +15c on top of Idle/Load temps to get the actual core temps. And it's still an incredibly low temps for a high-end air cooled quad at stock settings.
*Maybe my lapped job did the trick;)

I've also posted the temp readings from BIOS and Asus AI suite as a reference. Those temp are always lower than the actual core temp.
So after you've added +15c on top of the core temp reported from Speedfan 4.32, the core temp is accurate and does get higher than the temp reported from Asus AI Suite and BIOS.:)

Here's is another reference temp reading/OC from my previous setup before I just swapped to the G0 Q6600 last night.
This is just to show you that Speedfan 4.32 is actually picking up the core temp accurately given that C2D has Tjunction of 85c instead of 100c from the quad.

3.73 at 1.4vcore is excellent for this quad. Temps are pretty good too. My L631B with 2 cores runs 60C under load. Finally, some results to think upon.

Looks great for temps. I didn't look at mine at stock but when overclocked to 3.4 GHz, SpeedFan is reporting 52C top under load (forgot the +15C thing so 67C on air is not bad). I didn't try with lower voltage yet.

You should cos I wasn't very happy with my OC'ed E6700 temp using the same TR U120 X (it was severely CONVEX!) hence the 6 hours lapping job and finger cramps.

Very good question, ambient indeed, it's summer time! and a sunny day today.
RIght now in the early morning, the current temp is roughly 21c but gets 30c+++ by the afternoon.

Xilikon

07-25-2007, 10:09 AM

Please try 3.4 GHz and see if you can do better than mine. If you do, I might lap my SI-128 (same base as yours, might not be flat).

Coretemp 0.95 works in Visa x64, running it as admin should do the trick.

Nice clocks on the quad, only thing that's keeping me from buying one is the knowledge that 45nm is really close too. :D

Boo...I want better temps too >_< May I ask where you got your info for lapping your heatsink. I know my chip can go much higher than 3 Ghz.

Also, did you buy some kind of lapping kit or did you buy your stuff from various places?

C'mon, you know the answer already..do I really need to prove it to you?;)
EVA2000 has already proven that P5k-Dlx is the best mobo right now for quads - 480+FSB instead of the ~420ish FSB in the past with P5B-Dlx or badaxe2 in your case

Boo...I want better temps too >_< May I ask where you got your info for lapping your heatsink. I know my chip can go much higher than 3 Ghz.

Also, did you buy some kind of lapping kit or did you buy your stuff from various places?

It's fairly easy to do the lapping if you follow the steps correctly. You can do a quick search for heatsink lapping and hopefully you will find the answers you need.

I didn't buy the lapping kit for myself but I know many others recommand EasyPC kits. If you can get "3M imperial wet/dry sandpapers" locally for a reasonalbe price, then just buy some locally.

For my Thermalright Ultra120 Extreme, the heatsink's base was severely convex, take my words very literally. Hence, took me 6hours to lap it. In such severe condition, start with 320grid then 400 - 600 - 800 - 1000. You can stop right here as going up any further will come to a point of no significant performance increase. but I still go from 1500 and then 2000.

I'll post more pics on the lapping process in the air cooled forum so you can the transforming of the copper base and the # of sheet(s) I've used to lap it.

Hi michalcoughliN, I've seen you participating in the E6850 vs Q6600 or alike threads for the past weeks and I know you prefers a highly clocked E6x50 rather than G0 Q6600 but I'm the other way around. That's becouse I already have a golden E6700 that can be OC'ed to 3.8ghz stable at 1.46v underload. Hence, I don't want to take the risk of getting another C2D E6x50 and worry that if I'll fall into the no luck side like we all have read the thread "are all G0 too good OC'er..NO"

Well I gotta say believe what you originally believed it. I hope to see your highly OC'ed E6850 near 4ghz @ reasonable volts ;)

Subscribed for more OC result.

Next goal, 3.6ghz on air!

Stable up to 14mins but just failed from one of the cores.
I may need to start some tweaking but it's being an easy OC up to 3.6ghz so far :)

This is not fair ;_; Probably should have asked you before, are you stress testing using small FFT, large FFT or blend? Are you testing on a bench, open case or closed case?

Easy there ;)
As you can see from the prime, it's small FFT, max load on CPU and little on rams. I've already known my max OC on my rams so it's out of the case now.

It's in close case but highly ventilated Antec 900 case.

Pleae refer to m sig for my complete air cooling method and configurations.

1.35v @3.6Ghz on air

FAINTS

i don't believe the temps though>>> not doubting you but the fact something has changed with G0 temp reporting

it is impossible to idle below ambient temp so add another 20C if uncertain :D

btw QUAD and mobile CPUs have always had 100C tjunction

CedricFP

07-25-2007, 05:31 PM

Wow, 3.6 @ 1.35 - if P95 craps out after 14 min, I'd say that thing will run forever at 1.4v REAL (so allow for vdroop.)

Great chip.

I notice you have an A batch code - I wonder if "B" CPU's of the G0 series will generally clock better, like with the B2 and B3's.

Kougar

07-25-2007, 06:31 PM

Amazing results, but with one, possibly the current best air cooler too! If you can keep this up I'm going to stick with my intent to get a Q6600 instead of a E6850! An extra ~500Mhz OC isn't worth the loss of two cores to me :)

his assumption is W.R.O.N.G. :)

what matters though is that he is stable at those clocks

temps we will disregard until people figure out what's changed with G0s

Well, wrong or not, we know there is no way it is loading @ 47C on air, lapped Ultra 120 eXtreme or not, unless he has it sitting in a freezer.

XtremeTiramisu

07-25-2007, 06:50 PM

The moment you all have being waiting for: 3.6ghz Prime stable on air!

1.38v loaded and *62c = 47c + 15c (Actual max Tjunction is 100c)
Ambient temp = 29c right now in the summer afternoon!
Overall it's one helluv killer chip! :D

I believe that SpeedFan 4.32 assumes a maximum junction temperature of 85C for the Quads when it should be using 100C. You need to add 15C to the SpeedFan reported temperatures.

Reported Temps = TjMax - DTS ( DTS is the on chip digital thermal sensor reading )

This guy on [H]forum explained better.
I'll try getting core temp 0.95 to work on my Vista x64. (I remember I did also tried run it as admin but to no avail..)

29C ambient outside maybe

but not in your room :p:

look at your system/HDD temps

they should be in mid-high 30C should they not unless they are G0 revisions too :D :D :D :D

have you tried 3.7Ghz :D

Kougar

07-25-2007, 06:55 PM

N7, of course I can read. :yepp: With that extra 15c or not, it is impressive for air. Even with an extra 15c his temps are not much higher than my E6300 at 3.5Ghz, despite the higher clocks and 2x the cores with 4x the cache on them. Heck my temps match his when I hit 3.74Ghz, and I have a full blown WC loop for just the CPU.

Yes it's still stable as of now.

I still so excited to know that this new Q6600 G0 runs cooler than my golden E6700, it's unbelieable. I wasn't having high hope for running quad on air, even with a lapped TR U120 X but it looks like it has helped:clap:

Good chip, but your temp are wrong ... no tool can read G0 temp correctly now ...

Look at Priming or Orthos for Throttling of Cores, on this chip throttling starts at 75 degrees ... you will see, if your cores are throttling temp is above 75 degrees ...

It's not as hot as during the day time now, ambient temp has dropped down to 23c from 27~29c in the earlier in the afternoon. Hence, core temps dropped a little too :up:
I'm sure 3.6ghz on air isn't the max stable OC just yet but it's the final stable OC at this stage.
I'm going to test max FSB and suicide screenies later as per the demands. Hopefully 4ghz on air suicide screeny ! :D

Who says I'm a folder..lol
My primary goal in OC is run my system in maximum OC'ed state for day to day use.

BUT, of course I'll test out the max FSB and some suicide screenies just so I won't get kicked out or get flamed from our lovely "XS" community:p:

Regarding Vista, it's actually x64 Vista that's kind of annoying cos Coretemp/Intel TAT isn't supported no matter what I tried.
Vista 32bit worked flawlessly though!

But I've another pair of 2GB ballistix tracer 8500 kit that I want to use for a total of 4gb configuration so I kinda want to keep x64bit Vista.

I can finally use Coretemp 0.95 in Vista 64 bit. Please use the following FYI. :)

All you have to do is type "cmd" in the Search Box included in the Vista Start menu. Next, press Ctrl + Shift + Enter to open a command prompt window with elevated privileges. Now enter bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS in order to disable Driver Signing and reboot.

Exactly as what others and I have stated, Speedfan's core temp + 15c = Coretemps core temps.
It's always your CPU Tjunction temp (100c) - DTS = core temps. Coretemp 0.95 can read the max Tjunction of the Q6600 G0 at 100c properly but Speedfan assumes the max Tjunction for the Quad is 85c like all C2D. In the end, either programs give accurate core temp readings.

so you actually think that your temps are accurate as reported by coretemp now

i'm having trouble digesting that man

XtremeTiramisu

07-25-2007, 11:35 PM

Ok, to make this clearly, I'll re-quote this informative quote from unclewebb

I believe that SpeedFan 4.32 assumes a maximum junction temperature of 85C for the Quads when it should be using 100C. You need to add 15C to the SpeedFan reported temperatures.

Reported Temps = TjMax - DTS ( DTS is the on chip digital thermal sensor reading )

In CoreTemp, go into Options and select the option that displays how far until Tjunction. Apparently that'll give you accurate temps then (you just do Tjunction - reading to get the actual temp).

Tested using x6 and x7 multiplier:

FSB 502+ = Black screen

FSB 501 = Could POST but extremely unstable. "Unknown CPU is detected, update BIOS is required to unleash its full potential!"
- Maybe future BIOS update will enhance FSB flexibility on quad cores..

maybe you need to tweak NB voltage and vtt for the 480 stability.. :D

very nice results.. push some more if you have time.. :D really good to see Q6600 G0 quad on the run.. :)

here only B3.. I need to wait for G0.. :D

P5K-Dlx is known to take quad OC-ability up to the next level without a doubt ;) and I guess I'm just lucky that I've got a really good batch. I guess this is a pay back for over a hundred of $ restocking fee I spent to get my golden E6700.

NB/FSB voltage obviously set to the max without questions. Reference voltage for CPU/NB also set to higher x63 and x61 strength. CPU PLL voltage set to 1.8v max.

Dissable DRAM static read control as well...basically I tried everything within my knowledge and experience with the P5K-Dlx.

Yes, please read my first post regarding the relation btw BIOS temp vs Coretemp vs Speedfan vs non-DTS based temp reading softwares ie. Asus probe or Asus AI suite.

I use Asus AI suite to show the idle/load voltages and they're the same as in the BIOS so it's accuractly enough to take them into account. It's also good for reading the RAM's load voltage and monitoring all fans.

Please don't make me explain the relation btw BIOS temp, non-DTS based temp reporting software ie Asus probe or AI suite, Speedfan 4.32 and Coretemp 0.95 again. If you've followed up my updates regularily throughout the 4 pages in the thread, you'll have a clear idea how accurately are the temps. Although the temps from this and that all reads diff but at least THEY CORRESPOND to one another in a way, and this the key.

Mate, you'd be better off using the 9x multiplier with a lower FSB. With a quad core, you'd do better if you stay below 450 MHz on the FSB as far as stability goes. :)

Try 422 x 9 and see if you can get that prime stable!! :up:

Thanks a lot K.I.T.T, your advice is well taken!
And you've given you advice at the perfect timing becouse I seems to be hitting a wall right now at ~3.7ghz. Maybe I should try the x9 multiplier cos I know I'm starting to get near the max stable FSB from the Q6600 G0 and P5k-Dlx combo at ~480ish.

OC Status Update: Obtaining a new high record!

Unfortunately, things did not get smooth sailing as soon as I challenge my Q6600 G0's max stable OC. At 3720mhz, I can easily go into windows and do regular tasks at relatively low 1.41v but it's definetely not prime stable at this given Vcore.

I tried to get preliminary prime stable result with each Vcore interval increment and I finally stopped at 1.55v set in BIOS. 1.55v set in BIOS = 1.5200v idle and 1.5120v full load. At this given Vcore, I was having difficulties in getting prime stable in less than a minute run.

FSB 465 x 8 multiplier were the settings for 3720mhz.
I know I'm near the boundary of my Q6600 G0 and P5K-Dlx's max stable FSB overclock, so even with relatively high Vcore, prime is not showing stability for the current OC stage in less than a min.

I'm going to try to pass the OC beyond the previous 3.6ghz prime 8+ hour stable thredshold using the default x9 multiplier.

More results to come :)

FSB 460 x 8 was able to run prime's 3 tests for a couple mins before it failed, which is a little better than FSB 465 x 8. At this point I'm still trying to figure out whether if it's my air cooled setup that's reaching the max OC-ability for Q6600 G0 or may be that the CPU is near its max FSB OC or the motherboard is starting to show instability support at high FSB OC.

FYI, at those temps, you reached the limits. That's exactly what I experienced myself when trying to prime at 3.4 GHz, 1.4v and it failed after 3 hours (rebooted itself). The temps is hovering around 72C on the hottest core from CoreTemp 0.95. Since yours is bigger and lapped, you are able to push it further but obviously, we got similar results and we are just temp limited.

I guess that for 100% stability 24/7, we should try to keep it under 65C under max load. 70+C is on the borderline of stability, hence why Intel wrote a Thermal Specification of 71C (http://processorfinder.intel.com/details.aspx?sSpec=SLACR) in the docs, which might be the tripping point.

In my case, it's about the egg and the chicken because if I want to keep it stable, i need to raise the voltage but to lower the temp under 70C, i need to lower so I'm confused which one is causing crashes (too high temp or not enough voltage). For now, I will back down to 3.2 GHz for 24/7 use till I finish my watercooling setup. Your results gave me a good reason to invest in watercooling because I truly believe the G0 Q6600 can go to 3.7-3.8 on water for sure.

For sure, congratulations on your awesome results :)

Thanks Xilikon, you've provided me some more insight on the quad.
It's good to know that the G0 Q6600 thermal spec. is actually 71c instead of 61c for none G0s. Intel just updated the G0 processor infos these couple days I guess.

Yes, one of my three assumption is that I'm reaching air cooling's max OC potential for Q6600 G0 but let me tell you that K.I.T.T who made the reply above you is actually the one who's right about the obstacle I'm facing right now...;)

XtremeTiramisu

Looks like I'm having better luck with x9 multiplier. Currently set FSB411 x 9 to get 3699mhz or 3.7ghz ;)
1.500v BIOS set = 1.464v idle and 1.4480v full load. I can try lower the Vcore one or two interval lower at current clock speed.
My goal is to find the sweetspot that's under Intel thermal spec of 71c for Q6600 G0. :)

The Ballistix 8500 tracers kit is actually capable of going up to ~DDR2-1200 @ 2.2v on the same P5K-Dlx mobo I've now. The divider has always being set to 4:5 divider and becouse I'm using x9 multilier and FSB415 right now so it appears in lower than its original stock speed.

Very nice - Congrats on the new chip!

BTW, I know you've read up on the Tjunction issue, but it's possible (probable) that was also increased by ~10-11C with the new stepping, which would make it 111C now, instead of 100C. I think at this point we just don't know yet what the value truely is supposed to be.

Could you do your next screen-shot with CoreTemp set to display the distance to Tjunction? - that's the only important/meaningfull number - how far you have to go before the cpu throttles itself.

http://skinprops.com/images/ct095.jpg

...of course the only reak meaningful information is whether or not the system is stable at some setting, but if you use that option above, it will help you determine 'why' it might not be stable at some setting :).

As per requested:

Tjunction Remaining.
My brain is too tired to work out the calculations right now, care to do that for me? :D

Edit: Nevermind, I'm too eager to find out myself so I just did the calculation and it's indeed Tjunction at 100c.

100 - 65 Tjunction temp remaiing = 35c Idle Coretemp.

Take 35c Idele coretemp's value and - 15c = Speedfan's idle temp readings (It reads 85c Tjunction instead of the actual 100c Tjunction from the Quad6600 G0)

100 - 65 Tjunction temp remaiing = 35c Idle Coretemp.

Take 35c Idele coretemp's value and - 15c = Speedfan's idle temp readings (It reads 85c Tjunction instead of the actual 100c Tjunction from the Quad6600 G0)

Actually, that just confirms that CoreTemp is using 100C for Tjunction :). The issue is that it might supposed to use 110C or 111C (or some other value between 100C and 127C - Intel hasn't supplied this info yet). So unfortunately, it doesn't tell us what the actual Tjunction value should be for this cpu/stepping.

So, what I'm suggesting is that you use that option in CoreTemp, so you can monitor the DTS value, as it counts down towards zero when you're overclocking, under Load. If it's getting down in the 5-7C remaining range, you'll know that you're about to get throttled.

Always nice to see those cherry picked ES only serves as a kick to see but not well enough to be considered as a reference for the general public.

1. He's on open bench.
2. I don't see anywhere he has posted prime stable or related...
3. He's on XP OS
4. 1.57v idle @ 4ghz does not impress me as being an ES sample even. This is 1.6v+++ Vcore set in BIOS. With that amount of Vcore I think I can acheive possible the same if not, very close by my speculation at x9 multiplier. But I'm not interested in taking my beloved chip to the beat...not just yet or at least for quite a while.

Totally not comparable but definetely fun to see nonetheless being our G0 ancester ES week 712A.

The temps and o/c vales are truly amazing speaking as a B3 stepping Q6600 owner. There are a few wildcards to me though... tell me what you guys think:

1) Vista 64-bit OS... can you use XP 32bit and confirm the temps under load?
2) Stepping of the chip could have a higher tjunction -- others have mentioned it but I don't know if it's 100 °C or not.

I did find the g0 stepping on Intel's processor finder (http://processorfinder.intel.com/details.aspx?sSpec=SLACR), but I can't find any mention of the tjunction.

3) The P5K-Deluxe could somehow be reporting temps that are different.

If you are still in a room that is in the 25 - 29C ambient range, if I was you I would not trust these temps. Your "system" temp and your "HD0" temp are at or below ambient.

If it was me I would install XP and see if the temp readings stay where they are. I am not trying to say you are cheating, just that maybe the 64 bit OS is not compatible with the temp monitoring proggies. If I am right you may well be burning up your CPU without even knowing it.

I'm finally back.

Alright, very nice to know that a few of you can also bring the Q6600 G0 baby up to 3.7~3.8ghz range. It's definetely something out of the norm and amazing. For those of you who also got yours up to ~3.7ghz what was your cooling method, ambient temp and relative Vcore? It's always nice to make some comparason :)

Also my VID is 1.2625 so this generally means the chip has better overclock-ability @ lower given volts for the same clock as the same chip running at same clock speed. For example, someone need 1.45v to get 3.6~3.7 stable but I only need about 1.38v load to get 3.6+ stable.

VID doesn't determine your overclock-ability in terms of your chips' max FSB or clock speed but it has to do with the voltage that's needed to acheive those speed. At stock speed 2.4ghz, we each start off with different voltage being different VID from chip to chip. I started of at 1.23v (1.26v VID) at 2.4ghz and some may start off at 1.28v (1.30v VID) at the same 2.4ghz for our Q6600 G0s.

An update on the new high OC progress:

You guys all know I'm testing my xtreme quad OC on AIR right so ambient def plays a very significant role here. I was having terrific luck running 3780mhz at only 1.45v load with ambient temp being 19c~20c in the early morning.

Now the ambient has rise up to 26~28c all afternoon and it's considerable warm at the current time - 7:30pm PST so I need to back down on the clock : volts a little bit. So far I know for sure of is that this chip is capable of getting prime stable at 3700mhz ++ that's for sure. 3.8ghz may even be possible if we're on a different season :p

But you gotta love summer time and the sun shine and we're all hiding inside OC-ing like bunch of geeks...lol no offense, saying that including myself :p
So I'd say Max stable OC for this season will be in the low-mid 3700mhz and given that, it's still an outstanding OC on air. Expect 3.8ghz+ on air towards the end of the year ;)

This screen shot is just to show the effect of increased ambient temp and its relation to the core temps.
50min+ Small fft full load on all 4 cores. (This isn't the max stable OC if you haven't seen my previous screen shots)

Even at 3700mhz and a little higher is still consider as safe and stable for running it daily as long as you strictly keeping your 4 x 100% load 4 cores prime temp down below Intel Spec's 71c. :)

I'm sure none of the applications I do will ever get all 4 cores to run like prime..lol hence much lower core temp in the end. But I just want to use Prime's 100% x 4 cores temp as my standard.

Not quite unfortunately.

Thought I would grab this mid prime to show the vdroop.

Set at 1.56v in bios. Idle at 1.51-53. As you can see 1.45v at load.

Didn't realise your tests were small FFTs. All my previous tests were blending. Seems blending is just a tad more difficult to get stable, but runs cooler than ffts. My PWM temps are looking good:)

These temps are cpu underwater. Aircon fighting a warm Thai day.

Similar result but not quite the *same* unless his VID is exactly as the same as mine at 1.2625v ;)

Also it seems like RTL is on high-end water cooling setup + Priming in Blend instead of small fft which will produce even more heat.
His ambient temp will also vary his overall core temp but not as much as air cooled quads.

I will not doubt his Q6600 OC-ability but he may ended up using a tad more volts than mine clock for clock.

But all in all, it's great to see the G0 Q6600 all have very good results :)

The future is here now! essentially, I didn't expect this day to come so soon, especially for air cooled quad core OC'ers :)

True, the new P35chipset Asus P5K series has the "voltage damper" feature that's very helpful in later stages OC. When voltage damper is set to enabled, it's always 0.008v droop from idle, same for C2D and C2Q. If the voltage damper is set to dissabled, you'll get more vdroop, hence lower core temp in the end and this may or may not be a good thing.

07-27-2007, 05:55 AM

When we seek Orthos or Prime stable, this usally means the OC'ed setting will be used as a 24/7 machine. Taking 24/7 machine into account, his given high voltage 1.63v in BIOS and 1.57v Idle to acheive 3.9ghz may already defeat the purpose of running it on a daily basis unless he doesn't give a damn about longevity of the nice new G0 chip. So it's pointless at this stage whether his G0 Q6600 is prime stable or not.

I can clearly tell by the way his screenshot was captured is that he's seeking for the max possible "bench-stable" OC'ed settings at this stage.

I know this thread is meant for Q6600 G0 Overclock-ability on air but don't missed that his nicely done 3.9ghz clock is on high-end water. :)

I wonder what's his temp are like at this OC stage on water and what could be the max OC-able speed with water cooling a G0 Q6600. It would be nice to compare whether hundreds of dollars invested in a watercooling is worth taking up the OC up to the next high level from proven 3.7ghz+ on air configuration. (Saying this becouse I'm thinking about watercooling, but short on fund :p: )

Well it would still last a few years at that voltage, so hardly a big deal considering the turn over of chips. If its prime its prime, temps and running costs aside. Its under water so I doubt the temps are as high as air.

In the real world 200/300MHz from a decent watercooling setup would be hardly noticeable. Doesn't seem to stop anyone, always want that little bit extra. Prolongs the chips lifespan and its nice and silent.

vcore set in bios about 1.55

To be 3.6 stable vcore was 1.45

Regarding chip's VID:

This is what I've answered in another forum for someone who asked the same questions on VID:
VID is also one thing that we can take into account to determine the chip's overclocking-ability in the later stages. Lower VID almost always means that the overclocking room will be more. Bcos you started off with a lower Vcore at stock clock, your chip may ended up requiring much less volts to acheive the desire clock than another chip that has a higher VID than yours at the same clock. Lower volts required to obtain your desired clock speed may also mean lower temp. :)

However, keep this in mind though, although I'm stating this all based on facts and statistics but this still doesn't guarantee the OC outcome in every case, just so you know:)

Told you you'd have better luck with the 9x multi :D

3.74 GHz on air is nothing short of amazing! :up:

Gotta say thanks for enlighten me ;)
I totally forgot about the x9 multiplier route as I was so used to x8 multiplier route with my E6700.

OK, here is another explanation I'm going to make again just so you're clear about the core temp reported from Coretemp and Speedfan4.32.

Obviously you've not being reading and following my every single post carefully throughout the 7 pages, and I understand the thread is long but the infos are all there actually.

1. Forget about Vista 32bit or 64bit vs XP OS enviroment for reading the core temp correct, let me tell you simply that the OS isn't not related to the accuracy of the core temp reporting. I think I've answered about the accuracy part to someone in one of the post reply I made from the previous pages. Tjunction - DTS = coretemp and I even had a screen per the demand asking to show the Tjunction remaining from the coretemp just to show that the core temp is actually picking up the 100c Tjunction properly.

2. Pay close attention again to all my screen captures that has Asus AI suite and Speedfan 4.32 in it and look for the time for the screen that was captured. You can see that the system temp varies throughout the day. My room temp is actually 4~5c lower than the system temp reported. Do the calculations yourself and you'll find out my approx ambient temp. It's very similar to any others who also has Asus AI suite + speedfan 4.32 in the screen shots. However everyone's room conditions are different.

And obviously again you've missed the post I've made regarding the relationship btw ambient temp and OC'ed core temps in my previous page. Go dig it up and read it again.

People please don't make me explain things again for something it's already being covered. I have every motivation to show and explain all OC related subjects as clear and legit as possible so I'd hope you call can get it in the first place so no more time will be wasted from both party.

hey XtremeTiramisu is then any way you can show some 3DMark06 benchmark

Of course, this is also one of my primary goal after I'm fully settled on a max stable clock speed : voltage : core temp strictly below Intel thermal spec of 71c on air cooling setup.

Yeah I was thinking the same thing. He should try to get coretemp working.

Obviously you've not being following my posts closely enough and have missed the fact that I even made a post reply to help all others who need to get Coretemp 0.95 to work under Vista x64 OS in the previous pages.

Ladies and Gentlemen: Allow me to present you Prime Stable @ 3744mhz results !!

The system has being running nonstop for two days. So far Prime stable for 4 hours and 20mins and counting!
Overall this is one FANTASTIC chip that's prime stable on air at 1.4560v and still under Intel Thermal Spec's 71c :D I can't get any happier than this.
(Notice that my Ballistix Tracers 8500 are running below its stock clock? nevermind that bcos it's capable of going up to DDR2 1200 or 600mhz at the current given volt of 2.2 and timings ;)
My next screen shot in the near future will show much tighter latency at the current clock and voltage, hopefully)

Tjunction Remaining: Tjunc Rem + Core temp = MAX Tjunction temp for the G0 Q6600. (100c)
Is this clear enough Spanki ??

WOW, just WOW! You're slowly creeping up to 4.0ghz on AIR. Just crazy.

I purchased one of these bad boys (still waiting for it like many) and I'm glad to see a higher multiplier w/ lower FSB. You're assured me that having ddr2 800 that can ONLY go to about 500 mhz will more than suffice. :D

3850 is getting close, then onward to 4000+!:up:

...Tjunction - DTS = coretemp and I even had a screen per the demand asking to show the Tjunction remaining from the coretemp just to show that the core temp is actually picking up the 100c Tjunction properly.

I think you must have missed my earlier response to this, but it's worth repeating...

Note that what I highlighted above may be misleading. The only thing your math proved was that CoreTemp was in fact using 100C as it's Tjunction reference value - not that 100C is the value it is supposed to be using for this stepping.

But we already knew that it was using 100C, because it was listed on the window :). The question at hand is whether or not 100C is the proper value. Note that Tjunction is not a register on the chip that CoreTemp can simply read to find out. It's basically looking to see which cpu is being used and using a hard-coded value, depending on whether it's a mobile, conroe-duo, allendale, quad, etc.

So, until Intel verifies what value should be used, we just can't be certain that 100C is correct.

What makes me think it's changed for the G0 stepping? Here's my reasoning...

1. Temperatures being reported for the new E6x50s are way off - obviously 85C is no longer the proper Tjunction value to be used for those.

2. If you look at the Intel alert/notice (http://intel.pcnalert.com/content/eolpcn/PCN107463-00.pdf) about the stepping change for this particular cpu (Q6600), you'll see the following:

Tcase for the Intel® Core™2 Quad processor Q6600 and Intel® Xeon® processors X3220 and X3210 on G-0 stepping has been increased by 11 oC. Tcontrol offset will remain the same relative to increase in Tcase which will help reduce acoustics

...also note that 'Tjunction' is also (and perhaps more properly) known as 'maximum Tcase value'. So, what Intel did with this stepping (in addition to some optimizations that allow lower overall voltages) was to "let the cpu get 11C hotter, before cranking up the cpu fan (and/or throttling itself)". This leads me to believe that the Tjunction value was also increased - maybe by 11C, but possibly by some other number.

I'd also note that (at least speaking for myself), there is some confusion/ambiguity about how all of these values relate to each other... Tcase, for example, is (as far as I know) the temperature probe in the center of all cores and is the one that the BIOS and most apps report as 'cpu' temperature, but the way the above is worded, they seem to be specifically talking about 'Tjunction' (or TcaseMax)... they've obviously increased the top-end value of the allowable temperature range.

Given all of the above, I think it's a fairly safe assumption that the 'proper' Tjunction value to use for a G0 stepping Q6600 is 111C - but we really just won't know until Intel shares this information one way or the other (the only thing they've said for certain so far is that the mobile cpus use 100C - at least at the time they said that).

So basically, I don't think we can say for sure what the core temperatures truely are, but for practical/discussion purposes, using CoreTemp's numbers is as good as anything else until/unless some clarification comes from someone who really knows. As mentioned earlier, the only truley meaningfull measurement is whether or not your system is stable at some given speed. If it is (and the voltage you're feeding it is not dangerously high), then it doesn't really matter what the temperature is.

That being the case, the more meaningful number that CoreTemp can give you is the actual DTS value (enable the "Show Delta to Tjunction" option). This tells you how much headroom you have left - regardless of what all the various temperatures are reading. XT showed this @idle earlier, but idle temps never have interested me :)... I'd like to see some DTS values for some of these overclocks while under load.

Tjunction Remaining: Tjunc Rem + Core temp = MAX Tjunction temp for the G0 Q6600.

I appreciate the enormous text (well, not really), but I don't think you're getting my point. Your quote above would more properly read:

Tjunction Remaining: Tjunc Rem + Core temp = 100C (which is what CoreTemp is currently hard-coded to use as the Tjunction value for the G0 Q6600).

In other words, the fact that the numbers add up to equal 100C, just means that that's the number CoreTemp subtracted the DTS value from - not that that was the value it was supposed to subtract it from.

If you add the DTS value to SpeedFan's numbers, you'll see that it's using 85C as the Tjunction value, but that doesn't make it the right number :).

Spanki

07-27-2007, 11:26 AM

..in other words, let's assume the Tjunction value is really 110C. If that is in fact the case, you're core temperatures will be 'reported' 10C higher than they are now, but the DTS value would read exactly the same.

If the Tjunction value was really 90C, then you're core temperatures will be 'reported' 10C lower, but the DTS value would read exactly the same.

In any case, thanks for posting the "Delta to Tjunction" shots... it looks like you've still got plenty (~32C) of headroom left - which is great!

When we seek Orthos or Prime stable, this usally means the OC'ed setting will be used as a 24/7 machine. Taking 24/7 machine into account, his given high voltage 1.63v in BIOS and 1.57v Idle to acheive 3.9ghz may already defeat the purpose of running it on a daily basis unless he doesn't give a damn about longevity of the nice new G0 chip. So it's pointless at this stage whether his G0 Q6600 is prime stable or not.

I can clearly tell by the way his screenshot was captured is that he's seeking for the max possible "bench-stable" OC'ed settings at this stage.

I know this thread is meant for Q6600 G0 Overclock-ability on air but don't missed that his nicely done 3.9ghz clock is on high-end water.

I wonder what's his temp are like at this OC stage on water and what could be the max OC-able speed with water cooling a G0 Q6600. It would be nice to compare whether hundreds of dollars invested in a watercooling is worth taking up the OC up to the next high level from proven 3.7ghz+ on air configuration. (Saying this becouse I'm thinking about watercooling, but short on fund )

First off congrats on your chip there:up: I'm struggling to get close to your results and as you know I'm on water.

I see your results which are at full load, tell me albeit the voltage dampening how close are those vcore readings to the ones set in bios? This thread is certainly selling Asus.

Spot on about the bench and 24/7 things. This is actually my work kit used for 3D, so all 4 cores are maxed out pretty regularly. Albeit I'm not quite as precious with this chip as I was with the QX6700, I'll be looking for something closer to prime stable 24/7. 3.7ghz is probably a good figure to consider. Make that an excellent figure:) Either way I'm still pretty smitten at being able to run those benches at 3.9.

As for the watercooling. I'm in Thailand here, so temps are evenly hot all year round. This makes watercooling a pretty easy choice. In addition I know that the bulk of the kit, rad, pump etc will get me through a few more upgrades.

That's the justifying out the way, but basically buying all these bits of kit are just part of the addiction. In no way helped by this forum:)

This whole tjunction issue really gets at the heart of the G0/B3 debate. In other words, if the tjunction from which you subtracting the DTS from to arrive at the core temp is really 111 instead of 100, the tests speedfan is reportings are off by 26 (26 too low); likewise, the coretemp temps are off by 11 (11 too low). I'd really wanna know the tjunction for sure before trading my B3 in for a G0.

But... here's the thing - if the new chips are actually 11C hotter than what's being shown currently - it doesn't matter - because they have 11C more headroom to work with (everything's relative).

- Since the G0 stepping 'generally' needs less voltage for a given overclock (YMMV), then they will 'generally' run cooler than B3 stepping. This means you can either run them cooler at the same overclock, or potentially higher overclock for the same temperature (by adding more voltage). Either way is a win (again, assuming you get a good chip).

- In addition to running cooler, they might (likely) also have that extra 11C of headroom to play with before overheating, along with a scaled fan setting (for anyone who uses PWM) to keep the system quieter at higher temps (the fans don't ramp up as early).

...having said that, if you already have a B3 that you're happy with, it might be difficult to justify swapping out for a G0 (I'd probably personally wait for 45nm quad-core parts). But if you just bought it after the price drop and can still return it... that's a different story :).

Hey Spanki, I'm starting to like what you've just brought. Really bright interpretations I must say :)

Totally agree with all above statements from you.
I'd hope that the Tjunction is actually 100c so I'll be happier with a smile but if you're right about the +11c on max Tjunction, I gotta say you've proven some very useful and informative knowledge and I'm impressed :D

Spanki

07-27-2007, 01:56 PM

The only thing I'd add, which may or may not be obvious is...

- A G0 stepping Q6600 at xxxMHz @1.5v very likely runs the same temps as a B3 stepping Q6600 at the same xxxMHz @ the same 1.5v.

...it 'might' run a bit cooler due to some of the lower-voltage-optimizations part of this stepping, but maybe only a few C, if that. The primary factor is still how much voltage you're applying, so the benefit (if any) of the G0 would be:

a. because you don't have to apply so much voltage to get to the same overclock.

b. even if you end up having to apply the same voltage, you have more temperature headroom to work with, which might let you push it higher (or at least stablize an otherwise twitchy overclock).

...also note that 'Tjunction' is also (and perhaps more properly) known as 'maximum Tcase value'.

snip

I'd say that's close, but Tjunction and Tcasemax are not the same thing. Tcasemax is the maximum temperature for the IHS. Its on page 74, here (http://download.intel.com/design/processor/datashts/31559202.pdf), 62.2C for the B3 Q6600. The Tjunction is the on die temp, Tjmax is the maximum die temp. Tcontrol is the delta to the the thermal trip point TCC and has a negative direction -ve, as the the core heat increases the Tcontrol tends to zero. TCC is the throttling temperature. There is some debate, but Tjmax is not TCC. Tjunction is a generic value for a cpu type and the TCC value is the factory set value and can't be read externally, probably within a few degrees. So programmes like coretemp are accessing a register or assuming a value, if thats assigned correctly or reflects the actual Tjmax is a different matter.

Tcase for the Intel® Core™2 Quad processor Q6600 and Intel® Xeon® processors X3220 and X3210 on G-0 stepping has been increased by 11oC. Tcontrol offset will remain the same relative to increase in Tcase which will help reduce acoustics
That's saying the Tcasemax is now 73.2C (71C (http://processorfinder.intel.com/details.aspx?sSpec=SLACR)), the throttling point has the same offset as before so TCC has also increased by 11C. The short of it is that accurate absolute values are problematic, different programs use different values. Coretemp could well be reading the wrong register values for Tjmax and its not the 'actual' throttling point. Without an overheating throttling chip and a thermocouple attached, its still going to be guess at an absolute value.

Have a read on these links it might clarify a bit on the finer details. The first one is where I've tried to explain it as best I can; but you're right the deltaT via DTS is all that really matters. In techno speak its, "PROCHOT# is activated when DTS=0 for the maximum safe operating temperature."

One point though, if you know the temperature of the air blowing over the HSF and you know the approximate thermal resistance of said HSF. Then for stock voltage and speeds then the chips wattage will be close to the curves specified by Intel specs. If you know that lot, then you "should" be able to calculate an approximate value for Tc. At least then you'll know how accurate the PECI bios temps are! There's a worked example in the link above if you can be bothered.

The only thing I'd add, which may or may not be obvious is...

- A G0 stepping Q6600 at xxxMHz @1.5v very likely runs the same temps as a B3 stepping Q6600 at the same xxxMHz @ the same 1.5v.

If the G0 has a lower vcore at default that the B3 and ends at the same vcore at a higher clock it could end up using MORE power even with a lower TDP. The additional power used comes from change in voltage squared. Obviously its not very likely as a lower default vcore generally means a lower vcore for the same clock.

1. Q6600 B3 @ 3.6GHz 1.275v stock, 1.50V oced.

Pd = 105*(3600/2400)*(1.5/1.275)² = 217W

Suppose for a G0 a lower stock vcore and TDP, frequencies the same, so its the change in voltage that counts. Its using more!!

2. Q6600 G0 @ 3.6GHz 1.20v stock, 1.5V oced.

Pd = 95*(3600/2400)*(1.5/1.20)² = 222W

Now if it uses less voltage, but the same overvoltage delta. Which is fair if its the same process.

3. Q6600 G0 @ 3.6GHz 1.20v stock, 1.425V oced.

Pd = 95*(3600/2400)*(1.425/1.20)² = 200W

May I point out. I have been staring at the Antec 900 for quite some while now and reading up on it. That may have alot to do with your temps also. Since this case while not the greatest is amazing at air flow, being where the heatsink sits sorrounded by fans with amazing intake from the front.

i also just got an L723A930 same as ICER.

i easily expect 3.4 to be my 24/7 with this at great temps, on air.

time to go lap and take this e6400 out for good and sell it to a lucky fella in georgia who can take it to its limits.

excited to join all you other q6600 fellas in our quest to test these slacr's out.

this stepping's VID is 1.300v as ICER's is, same stepping :(

my ambient temps are pretty high in here about 80F which is about 27C so at 3.3ghz my voltage is at 1.375 in bios, 1.33v in speedfan idle and 1.28v in speedfan under prime95 load all 4 cores.

temps are about 65-66 load under the above. all prime tests listed using small ffts.

i want watercooling :( or to get my new apartment soon. if i was at a ncie 21-22C in my ambient, whole nother story.

time to start researching a good affordable starter WC rig.

i ran this chip at 1.4+v in bios and ran close to 3.6ghz with prime going on all 4 cores and temps were hovering at 70c which i dont like. again ambient temps messin me up on air.

air is so dependent on ambient. i am measuring core temps in coretemp and voltage in the latest speedfan.

Now if it uses less voltage, but the same overvoltage delta. Which is fair if its the same process.

3. Q6600 G0 @ 3.6GHz 1.20v stock, 1.425V oced.

Pd = 95*(3600/2400)*(1.425/1.20)² = 200W

WOW!
Fornowagain, you really know your stuff!:clap:
Thanks so much for typing out all that useful knowledge you've.
I never know how to calculate the watt usage for my OC system but I think I got it now, much appreciated for sharing!:D :cool: :up:

Thermal management for the box intel Core 2 familiy:

http://www.intel.com/cd/channel/reseller/asmo-na/eng/299986.htm

Basically look at the chart on the bottom of the page and it shows the Maximum Case Temperature in celcius for B3 is 62.2c (105w thermal design power) and 71.0c (95w TDP).

Now for the fun of it, here is my xtreme OC Q6600 G0 watt usage calculation (Thx again fornowagain ;) ):

* Q6600 G0 @ 3744MHz 1.224V (LOAD) stock, 1.456V (LOAD) OC'ed.

Pd = 95*(3744/2400)*(1.456v/1.224v)² = 209.70W

Performance gained: (3744 - 2400)/2400 = 56% OC'ed !

I think both results are fantastic for an xtreme OC'ed quad core on air :)

Nice chip! I got my g0 from ncixus.com. It's a batch# L723A930. I'm currently running at 3.6(9x400) on the stock cooler sitting in the high 40's idle. I just wanted to see what she was capable of. If she hits 3.6 @1.40 bios 1.36(speedfan) on stock intel cooling, i've got high hopes what she'll do with the waterkeg III and d-tek fuzion I just ordered :)

1. Temperatures being reported for the new E6x50s are way off - obviously 85C is no longer the proper Tjunction value to be used for those.

I compared the reported load temps of my B2 E6400 to a new G0 E6550 and at the same MHz, core voltage and room temperatures, our load temps were almost identical. For both processors, TjMax is assumed to be 85C.

The idle temperatures for his E6550 were being reported below ambient which is impossible but my B2 E6400 can also report idle temperatures below ambient. That doesn't prove that the maximum Tjunction isn't 85C. It might just be that the data coming from the on chip digital temperature sensors isn't accurate at low temperatures. These sensors are designed and calibrated for managing the thermal throttling and thermal shut down of the processor. No where does Intel document their use for measuring idle temperatures.

My opinion based on readings from an IR thermometer is that they are very accurate from 50C to 100C. Below 50C they lose accuracy and when used to report idle core temperatures, will usually report readings that are too low.

I believe the TjMax for the new Q6600 is likely 100C as CoreTemp 0.95 is assuming but without any documentation from Intel, I'm only guessing and so is anyone writing temperature software.

None of the above matters if you set CoreTemp 0.95 to "Show Delta to Tjunction temp." CoreTemp is accurately reading that Intel documented register and displays it in real time.

If you're doing some serious overclocking and you're running stable you really don't have to worry too much about temperatures. When fully overclocked, you'll lose stability before you reach the throttling point and you won't get anywhere near the THERMTRIP# shut down point.

Just earlier today I started focusing on OC the rams and starting doing prime blend stress. It's a bit difficult to get stable than small fft but now it's priming away after I changed the NB reference to x0.67 from x0.61 (much more detail BIOS configuration for P5K-Dlx will be disclosed FYI ;) )

Ram isn't complete stable at this speed and given Vcore and timings but it's stable enough to do anything else besides prime blend as I'm typing you this msg :p

XtremeTiramisu send me your CPU to test for a week! My Q6600 B3 is STRICTLY limited to 3.0GHz because load temps hit ~71 degrees celcius with only 1.35625vcore on fairly high end air cooling! Will flash the BIOS later this week to see if I can find any improvements and/or exploits.

Interestingly, look at this;
http://processorfinder.intel.com/details.aspx?sSpec=SLACR (G0 stepping)

I'm running 4 cores at 3.6 GHz 24/7 (with nice temps) and can boot into windows vista @ 4GHz. True, it's not Orthos stable at 4GHz but I can run some Pi....all on air.

FSB 466 & 470 * 8 PRIME STABLE Preliminary Results !!!:

So I've being trying to stabilize my rams all night and I finally found out what makes my system having difficulties getting Prime Blend stable.
You guys probably have all seen my current highest OC on air with Prime Small FFT stable screenshots but with the same settings, Prime Blend will immediately fail at Test#2 in less than two mins.

After I change NB Reference voltage from x61 to x67 and the rest of the remaining configuration left the same, I can immediately Prime Blend stable for several loops.
So now out of curiousity, I say why not try the x8 multiplier route again for maximum RAM OC using 4:5 divider. Keeping the same current CPU clock speed.

So...I was WRONG about the instability using x8 multimplier to OC the CPU w/ P5K-Dlx. Now I really gotta thank my P5K-Dlx for what it can deliver....I'm 100% SOLD !

30mins + and counting (I really have a good feeling about this cos I was having tough luck even at FSB460*8 and not even Prime-able for a couple mins); next goal: FSB470 & DDR2-1175 !

http://img505.imageshack.us/img505/3631/fsb4663728primestable11qf1.jpg

Still using the same Vcore, I'm afraid I'll have to bump the Vcore by one notch.
But nevertheless, the mobo is completely happy with the Q6600 G0 at FSB470 and this is something that was not possible :)

You may want to find your most stable speeds with the 9x multi. instead of the 8. I think higher FSB can slow your chipset...run some benchmarks instead of prime & see which multi performs better at ~ the same mem & core speed.

The answer is FSB468*8 = 3744mhz scores significantly better than FSB416*9 = 3744 of the same clock. (CPU Mark 5432 vs 5366 respectively)
*I'm not sure if it's also increased ram clock speed from DDR2-1040 to DDR2-1170 made the improvment* Same 4:5 divider

I don't have the 5366 data anymore, I accidentally deleted it.
Expect further improvement in 3D mark 2.0/3.0 and CPU score with better Nvidia Vista 64bit driver and a clean install Vista 64bit OS. My system is preety clogged up being my test bed for the time being.

Nice job, and thanks for the tip, I'll try it on my P5K. I've been running into similar observations as you have with my board (Orthos blend OK @ 3.85, but 3.9 failing on my E6600). Were you able to find an explanation somewhere on the reference voltages in the P5K bios?

Ok, this G0 Q6600 is insane. I dropped the Vcore, raised the Mult, and the CPU runs cooler :) Prime95 Perfect, Orthos, no problems either. I think I will stay at 3.4ghz until I get a better cooler.

i dont think you are stressing all four cores. get the latest prime it launches 4 threads at once.

also, use coretemp to get real temps. speedfan temps are off by 15 i think. speedfan is good to check voltage though.

Either way (@chriskurn), doing 80% load on 4 cores @3.4GHz with a CoolerMaster Hyper Tx (~$20 heatsink) kicks ass :up:

that is because of different "FFT's" are used to excercise the cpu core...i think each FFT is run for 15 minutes before switching...you can customize it to a different schedule.

EDIT:...just re-read your post and i see you were referring to load not temperature...the above statement affects temperature

Chriskurn:

Yeah you should stay at your current OC state cos I'm a little worried for the kind of temp displayed in the screenshots you've provided above. Taking your current given voltage right now - 1.34v and 3400mhz but you're already at a similar temp as I'm running 1.44v and 3744mhz. I'm also looking at your system temp being reported as 43c shown in both speedfan 4.32 and Asus AI suite so that means your ambient temp inside your case is quite hot.

I'm assuming the ambient temp over your place in the summer time must be in the 30s. It's recommanded that you get a better cooler to unleash the G0 Quad full potential and fight the summer hell ambient:D

Next time when you show a screenshot of your load temp, please allow prime stress load to test at least 3 consecutive tests.
Looking at your time, you've only started less than 1 min and in test #1 stage, Prime Blend (less stress on the CPU)
So for you to get a better idea of the actual load temp, wait until Prime past the first couple mins; the system loads fluctuates and so is the load temp during the initial stage.
