XtremeTiramisu - did you lap your G0? Did you lap anything at all? What were your final voltages in BIOS? My G0 comes tomorrow, prepping up prior to.
graysky: Intel has never documented absolute temperatures for any of the desktop processors.
Anyone interested in an absolute temperature can use CoreTemp 0.95 and will get a realistic looking load temperature number but it is not documented and may or may not be 100% accurate.
What is fully documented by Intel is the DTS. It provides accurate temperature information that is relative to the thermal throttling point for any Core based processor. If you use CoreTemp 0.95 and set it to "Show Delta to Tjunction", you will be able to read the DTS in real time. If you do this, it doesn't matter what the real TjMax is and it doesn't matter what changes Intel made to the latest G0 steppings. The information returned by the DTS did not change.
Post a few links to any questionable G0 temperature readings and I'll have a look at them and try to come up with a reasonable explanation.
If you've seen the first post I made in the first page (All links have being fixed), you can see that my Thermalright Ultra120 Extreme is nicely lapped. The Q6600 G0's IHS isn't not lapped and it's not necessary to lap a G0 proc. The stock IHS is already preety flat and the Q6600 G0 runs very cool even on air cooled.Quote:

Thermal Compound Break-in Priod: it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

Core temp are 67~70c so this is what I'll have as my max 24/7 OC for this season.
Ambient room temperature is 24.9 to 25.1C measured with a digital thermometre; system temp is where the hottest place in my room. Ambient room temp is always 1~2C below it.

Again ambient temp in my room is measured from 24.9c ~ 25.1c.
It's very accurate becouse whenever people comes into my room, they felt it's uneasy to breath and hotter than other places in the house. When I brought the digital thermometre to my bathroom, hallway, livingroom, the temp drops considerable down to any where from 21c to 22c.
So, please don't question about the ambient temp in my room again.;)
your system temperature is 26 degree C, which is only 1 degree hotter than ambient temperature?

Thermalright Ultra120 Extreme (Lapped) vs Ambient Room Temperature
Ambient temp in the room when screen was captured = ~22.7C
As you can see the Idle temp is roughly 13~15C above ambient temp in my room.
NOTICE: Given Vcore Idles at 1.4880v, even so the temp is still amazing. :cool:
So without a doubt, the Thermalright Ultra120 Extreme is the best air cooled heatsink avaliable.
(For similar results, "lapping" the heatsink base is strongly recommended ;) )

My guess with the P5K-Dlx is that the P35 chipset should still recongnize the Q6600 G0 stepping regardless of the BIOS version. I'd worry if you've older chipset mobos such as the P965/975 or 680/650I SLI (without their newest BIOS flash).
I cannot guarantee if the Q6600 G0 will boot with older P5K-Dlx BIOS becouse obviously I didn't try it. If you can flash the mobo to the 0404 BIOS or newer before you put in the G0 that'd be great but if not just put it in anways and boot it up. Worst case senerio is the system will not post but you'll not kill it.
You worked out the chip is using approximately 210W, right? Having a look around the 'extreme' with a good fan mounted correctly could have thermal resistance of up to 0.1 C/W. Assuming its mounted well, then a fairly accurate way of confirming real world temps is to work out the delta.Quote:

Just add the case/room temp to the delta for Tc. So 21+23.2 = 43.2C The core temp is higher, opinions vary, maybe +10C. Gives an approximate junction temperature of 53C.
Thanks for posting this EPIC OC thread on the q6600. This gives me high hopes that my OC will be possibly 4.0ghz on water if i ever get my cpu from tankguys!
Thanks. Now that you've got 3.8ghz stable, lets go for 3.9! It seems doable.
Try Prime blend (or whatever gives large fft's) ;)

Temp wise, it peaks at 70c so it's still within my limit but it can go beyond that as you can see from my previous screen shots above.
As for 3.9GHz Prime stable goal? I guess I'll leave this to you watercoolers.
I'm already topping out the air cooled Q6600 chart with 8+ hours Prime stable screen shot. Clock speed : Voltage : Temp : Air cooling = I think I'm currently ranked #1. :cool:
Indeed, my next goal and I'm quite confident ;)Quote:

So far from the statistic of all Q6600 G0 I've seen, the norm would fall some where btw 3.5GHz ~ 3.6GHz with reasonable amount of volts.
Nevertheless, the G0 Q6600 has certainly raise the bar for what we used to thought a Q6600 could OC. Honestly, I really don't see a reason of buying a dual core when a Quad core can acheive the same or surpass the clock speed of most C2Ds :)
Very nice.
You're using a 2 GB kit?
and what vcore in bios? :)
I think with the right mobo & cooler, 3.6 sounds like a good avg. Even though I'm pretty sure my mobo settings are correct, I can't get a stable 3.8GHz. I am currently using the Thermaltake V1 cooler and am not real happy with it. My Idle temps are good but when I put a Orthos load on it, the temps get too high. It's like the eveready bunny, they keep going and going:rofl: I'd get the Thermalright Ultra-120 Extreme but it's too tall for my case... I'm going to buy the Thermalright Ultima-90 soon and see how it works.Quote:

More details in the complete BIOS configuration will be updated shortly.

But nevertheless, it's still smooth sailing @ 3760MHz on air :)

I think a correct re-wording of these specs for a Q6600 G-0 is that a CPU cooler must dissipate thermal energy at a rate of 95W to keep Tcase temperatures under 71C to prevent throttling at 2.4GHz.
Likewise, the QX6850 G-0 needs a cooler to dissipate 130W to keep Tcase below 64.5C for 3GHz operation.

It's still a gamble and luck of draw but I'd personally go with a lower TDP and relatively lower thermal spec CPU to OC than higher TDP + higher Thermal Spec CPU. This is how my logic and experience has given me.
The only way to really draw some clear statements is by accumulating enough OC database for the new X3220/3210 and compare them to the G0 Q6600
Yeah, noone's seeing G0 parts yet for those, so it might be a while before we know how they clock.
The interesting thing about the X3210 is that it can be found for ~$225 today (though you'll surely get a B3 stepping).
I'll be interested to see what kind of VIDs the G0 stepping Xeons end up with. You could make an arguement for either better or worse binning - but we won't know until we see some in action.

Maybe if I decide to lap my cooler, then I'll reapply the paste the right way!
FSB 470 * 8 @ 3760MHz 8Hrs+ LargeFFT Prime Stable - Final stable OC in the summer season.
As per requested, here's the 8Hrs+ LargeFFT Prime Stable screenshot at your disposal :cool:
LargeFFT Stress test is known to output the maximum heat, power consumption and stress to the entire system.
P5K-Dlx, Q6600 G0 and Ballistix Tracers all sustained the long 8Hrs+ torture at the given voltage : clock speed :clap:
For reference purposes, I have also attached the 8Hrs+ SmallFFT Prime stable screenshot below for you to see "a noticeable difference in the LOAD Vcore".
It appears that LargeFFT does actually puts out more stress so the Vcore further drops down to 1.4720v from 1.4800 OCCASIONALLY.
Whereas in SmallFFT, the load Vcore always remained at 1.4800 flat throughout the 8Hrs+ Prime.
So both results yields that the system is rock stable with its current OC settings :up: and I must say it again - What a FANTASTIC OC result on air :D :cool: :clap:

I'm currently stable at 3.2GHZ (355MHZ), 30/29/29/29C idle temps
Mem : 2.2v

1.2VHT : 1.40v
NB : 1.50v

any suggestions?
965 boards are not the greatest for overclocking quads. You'll normally run into a FSB hole between 360 and 400MHz. Try 8x401 which kicks in 1333 FSB strap(400 and below is on the 1066 strap). If it works then you can proceed up from there but don't expect to get much farther.
I see... did you mean 965 or did you mean 680i? The P5N32-E board is a 680i board.
Excellent thread XtremeTiramisu! Glad to see some really good results comming from Canada! I finally pulled the trigger on a Q6600 G0 and P5K premium on my watercooling setup! So my credit card is loaded because of you! :D
Don't worry ... I'm hitting that 360 FSB wall here as well on a 965P S3.Quote:

Having that Enabled costs nothing in terms of performance and it will alert you when running some poorly coded or malicious software that is trying to access memory it shouldn't be. It won't limit your overclock in any way.Quote:

bcdedit.exe /set {current} nx AlwaysOff
This WILL have an positive effect, trust me.
I just got my Q6600 from NCIX, same exact Batch #: L723A765 as XtremeTiramisu. It will be a week until I can get my D-TEK Fuzion on it. I'll keep you updated. :D

The only time having the NX bit enabled will stop a program from running is if it is a malicious piece of code executing where it shouldn't be or it's a poorly written piece of code that is likely trying to access an uninitialized null pointer. I don't want either type of code running on my system so I have it enabled.
If you would have made it to page 2 of that link I posted then you would have come across this page which I think is a very thorough document about the NX bit:

Everything comes at an price you know, and DEP for once is very well known to generate more problems than resolving them...
I also thought XtremeTiramisu was more inclined to getting the most out of his OC due to the vast amount of post and with the frequency he post them telling us about his fantastic chip...:rolleyes:
But Ok, if you wanna go out on the net between the benches and posting of results chasing some pron...well by all means, keep those things.:D
To the rest:
Try this:
1.Do a fresh upstart of your box, and wait 5 min. (Vista related)
2.scribble down your memoryusage, then bench something
3a. In Vista use bcdedit.exe /set {current} nx AlwaysOff
3b. In XP add "/noexecute=alwaysoff" to your boot.ini (without ")
4.reboot and disable Execute Disable Bit in BIOS
5.fire up the OS and wait 5min (Vista related)
6. scribble down your memoryusage, then bench something
..should be an eyeopener, taken honest reflection is given..(that is, leaving the ePenis out of the equation..hehe:D )
Thanks for the informative post Clint. Hopefully I'll have some time tomorrow to do some thorough testing.
Absolutely only my pleasure, together we make this board rock!:up:Quote:

Disable DEP / NoExecute Protection
DEP, otherwise known as NoExecute, is a piece of technology in Windows that prevents processes from being altered in live memory. This lowers the frequency of certain attacks, but it can also have some adverse effects and cause certain things not to run.
Due to the way Windows Vista™’s boot editor has been created, it is now harder to disable DEP / No Execute Protection. Here's how to do it:
1. Click Start, All Programs, Accessories, right click on “Command Prompt”, and click “Run as administrator”.
2. If asked for permission to run Windows Command Processor, click on Allow.
3. At the command prompt, type in “bcdedit.exe /set {current} nx AlwaysOff” (without the quotes).
4. You should receive a message saying “Operation Completed Successfully”.
5. Restart the computer, DEP / No Execute should now be disabled.
If you want to disable it in XP you will have to edit your boot.ini you'll find in root of your systemdrive
It looks like this:
ChangeCode:[boot loader]
timeout = 30
default = multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS = "Microsoft Windows XP Professional" /noexecute=optin /fastdetect
/noexecute=optin
to
/noexecute= alwaysoff
Now, if you have installed the dual core fix then you will have another switch there that we need to adjust for:
Make sure you'll have the switches in this order.
/noexecute=alwaysoff /usepmtimer
My boot.ini looks like this: (XP and 2003 uses the same switches)
:up:Code:[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Enterprise" /fastdetect /noexecute=alwaysoff /usepmtimer

So all this temp loving is from only lapping your TR120U EX and not also your Q6600?
6 hours lapping, don't your arms, hands and body hurt after that? :)

Thank you:up:
1. Go to your C: directory (or whatever your main OS HDD is on)
2. Tools, Folder Options, View tab
3. Select the dot box for "Show hidden files and folders"
4. Scroll down a little and uncheck "Hide protected operating system files"
5. Now the "boot.ini" file should appear in your C: directory
Sorry to be such a bother but its not showing on my computer, thank you pmisley, not inside them folders either.

sorry xtremetiramisu, dont mean to hijack your thread.
You have to goto folder options and advanced, and check unhide protected operating system files, and hidden files.Quote:

Any positive results so far from making this change and disabling Execute Disable Bit?

yes, i did, thank you to all. RLM did the trick, now to try it. thank you. again sorry xtremetiramisu... cheers
Yup, works great, tried it in aquamark3, gained 3000 points on that tweak alone. cheers
There you go!:up:Quote:

what is the difference of this in my XP Boot.ini, NoExecute=OptOut versus your recommendation to use NoExecute=AlwaysOff???Quote:

this DEP technology was there to protect the cpu and other programs from malicious virues or trojans, right?
SO...i presume if you have a very good virus protector installed, you or i can afford to turn this service off...is that how you see it?
looking forward to it already :up:Quote:

see my system temp, thats probably the temp in my room, may be 2 degrees higher, my portable ac is sitting right next to my computer.

are you using phase?
I was wondering the same thing.:yepp:Quote:

I'll be testing the new mobo with the existing golden Q6600 G0 and Ballistix Tracers 8500. My goal will be seeking for better OC-ability in 4x1GB configuration, hopefully. This is probably the only area I've to point out that P5K-Deluxe didn't impress me much but it didn't disappoint me either. I'll be expecting the Black Pearl to deliver lower temp and greater OC-stability at higher OC'ed state.
You guys should see the new thread by the end of tomorrow.
Looking forward to see you all participating in the upcomming new thread. :)
Sorry for the poor quality pics

Are you selling P5K-Deluxe? If price is reasonable I will buy it.Quote:

I finally had a chance to do some thorough benchmarking with the Data Execution Prevention ( DEP ) feature in Windows XP enabled and disabled. My test was to run 3DMark05 3 times with it enabled and then to run it again 3 times with it disabled. I rebooted after each individual run of 3DMark so the results would be as consistent as possible.
Here are my 3DMark05 results with DEP turned ON.

Here are my 3DMark05 results with DEP turned OFF.
http://img214.imageshack.us/img214/1...xofffx9.th.png
GameTest 1 - Return to Proxycon
ON - 59.47 fps
OFF - 59.53 fps
GameTest 2 - Firefly Forest
ON - 35.70 fps
OFF - 35.73 fps
GameTest 3 - Canyon Flight
ON - 67.80 fps
OFF - 67.93 fps
The overall average of these 3 games is a difference of less than one tenth of one frame per second. You better have a pretty good eye to notice that.
I think the benefit of Data Execution Prevention by enabling the NX bit is well worth the tiny performance hit. Disable DEP if you're benching for a new world record but I'm turning DEP back on.
You can run NXTest.exe to see the status of DEP on your system.

i agree with you, unclewebb!
I concur :DQuote:

Now how the hell do I switch DEP back on?
Execute Disable bit 'Enabled'
Bootini changed back to 'optin'
run nxtest, and it still tells me DEP is not activated.:confused:
RLM
Oh well, I tried..., who I'm I to tell you:rolleyes:
Super Pi would have been a better bench to use to compare on/off :)
Seems to get a positive out of nxtest you need to use 'AlwaysOn' instead of 'OptIn'. However this causes all sorts of conflicts in XP.Quote:

Back to sort of on.
RLM
All sorts of conflicts? I've had all my XP systems
running DEP ON, NO EXCEPTIONS for years and have
encountered nothing that seemed to fail with that.

Yes, but don't bother...it's clearly a matter of "ePenis" syndrome..:DQuote:

Or, perhaps a matter of priorities - for folks who don't consider SuperPi the defining characteristic of thier PC usage? :rolleyes:Quote:

This switch seems to turn it on for all programs except the programs you choose not to have it on for:

Look mate, like a lot of others here I was more than willing to try out what you had to say. An open mind.Quote:

I'll be the first to admit, relatively speaking that I'm an ignoramus.
That said, if we are missing something, then cut out the mysticism and back it up with some results.

RLM: After reading a statement like that I thought I was going to see a little more performance gain than what I actually saw.Quote:

hey Tiramisu!
have u tried reading (or could u) the W's ur PSU it maxing when all of this is @ full load?
TIA
PS: gj so far btw :up:
@RLM I find the following about DEP. May be it helps...
thanks for the great link...i rather increase my protection than eliminate it or cutail it to gain a few points in any bench or whatever!;)Quote:

Bookmarked now though, will take the time to read it through properly. Cheers:up:

I absolutely agree ! Also have a look at the last paragraph :Quote:

@RLM : Good luck, amigo !
