Just got a new Q6600 go and it runs 38C on core 0 and down to 28C on core 3 at 3G with defualt vcore full load on water with p95 for quads even if I change the hs position.10C diff? Also the VId is 1.325v. Posts at 3.43G at 1.6V but will not boot any higher than 3G. This is prolly a mb problem and will try in dif mb soon.
The outlook is not good for that chip. It's normal to have *some* difference in temps between cores but 10C seems a bit excessive. I'd say the IHS is probably not making good contact with all 4 cores which would be a flaw in manufacturing. Either that or the surface of the IHS is not flat. You might try lapping it.
1.6Vcore indeed for only 3.4ghz and not even stable seems way excessive to me... I think too it's rather mobo related ( are you referring to ya Asus P5N32 mobo ?) as this at all doesn't seem right... but the mobo ain't gonna cure the core temp difference....
I have a L738B233 with VID 1.325 on a GA P35 DS4 running at 3.5Ghz on air (stable) it certainly is not as good as my L734B164 that is running 3850 stable 24/7 water...Quote:

Barely stable, tried 5min OCCT and it seemed ok, core temp 58c on all 4's, about 2c variance.
Can boot on 400x9 (3.6Ghz), can Superpi @ 14.8sec, but not stable at all, suicide post only.
Crank that CPU up!
That does seem like high volts for a "GO". My Q6600 GO runs at 3.61Ghz @ 1.3v, the vid is 1.2125.
Yeap I've got a crap one, for the past 3 CPU's I've purchased, they all turned out to be crap clockers.
I think my motherboard is not able to handle the power draw neither, it's a P5K SE without any cooling on the voltage regulators. And during 100% load on all 4 cores, I can hear a very loud "hissing" sound from ther motherboard.
I've stuck a few heatsinks on it but it didn't improve the situation.
you guys sure have some good G0's there
i got a batch # ive never seen *L747
and even it needs 1.45 for 3.4
and ive tried up to 1.52 for 3.6 but it gets too hot for my tuniq and crashes
prime in 1min
The motherboard is a p5n32 e sli, it must be holding it back.Running 3150mhz at 1.45V stable, 40C max full load, will not boot 1mhz higher on any vcore.Tried up to 1,7V with 1 stick of ram.This mb will run my e6600 to 4G stable and post to 4.2G over 450fsb but I think my raid goes bad after that as it will not boot.
Sounds like your board is having issues supplying enough power to cpu is all. I started at 975x, 965, RD600, P35, and then X38...each clocked my wuad higher in the order listed, from lowest clocks to highest...
but anyway guys just wanna say i have a L738A730 that has a vid of 1.16
i build pcs for a living and started testing the GO quads in my own machine and none of the last 6 cpu's have been good clockers. i felt releived to put my own back in afterwards..... i started a thread somewhere about it.... i hope you have better luck next time m8. i'f i were you i would fry(by accident) it and send it back to the shop as faulty for a new one.... the vid was really high on all of them aswell....

My interest is that from the data that I have been collecting so far, the lower the VID the lower the temps at Higher speeds. From this I would expect your Q6600 to run at 3.6GHz on < 1.25v. You should be able to do 4.0GHz on < 1.375v.
So for Folks with a VID of 1.3250v my condolences, there may be the odd 1 or 2 out there that will reach 3.6GHz but you need alot of power. Also from observation, many of the Q6600 with the 1.325v VID may originate from OEM processors.
Vid is not the key just look at the bottom of cpu under the hsf.
There there is the wafer code.
For those who believe that have a good cpu the last two digits should
be closest to 00.
Example my cpu has vid 1.2875 but wafer ends to 500.
3.6@1.3 Volt on AIR. Just a thought but you can look into this...
Thanks
i will try but unfortuntely this cpu isnt mine anymore and will be leaving me tomorrow. so i will try to do what i can :)Quote:

eist and all that has been disabled all along.
I wonder if the walfer code is correct or not.
my code:
2L74036
4A0618
right now I'm running 3294 (366 x 9) @ 1.4375, still not OCCT stable.
Still need a lot of time to play with this chip, pleasing all 4 cores is very difficult.
The wafer code must be at 015 as maxed out as far as i know.
Beyond that is just luck.

I think this is theoretical mumbo jumbo as I can totally contradict this with my own findings with some CPU's E6600 and Q6600... I still think the wafer number and the A or B stepping ( or batch or whatever some refer it too ) are more important then VID... I had a few F and G CPu's that were total crap although they got the lowest vid I ever had on an E6600... but went up well till a certain speed and then required massive voltage to get any higher, also some had lower FSB walls then the higher vids... also the 2 Q6600 I own ( I already sold one to be replaced soon) had 2 totally different vids ( 1.2125 and 1.2750 ) both clock up to 3.6Ghz with minor difference in voltage...though temps are totally different , the first one is an A stepping second B and the B still gets hotter ( same finding as I had with other COre2 duo's )...Quote:

The L738B's are not all bad. This is what mine does. VID is 1.26

Imageshack seems to be acting up tonight so my screen shot isnt showing. I am running 3840 1.5v in bios. Water cooled 12 hr occt stable. I have been able to run Spi at 4320 mhz @ 1.62 vcore.
I got another OEM on the way hopefully I will get one more decent chip to make it two out of four...

if I was in the market for a new Q6600 and wanted one that would run at 3.6GHz with the least voltage requirements then I would certainly choose a processor with a low VID value.
There are other factors that determine how well a processor will OC, ie
1. The IHS contact with the HSF
2. MB chosen
3. Cooling System
4. Expertise of the OC'r
Here is a small sample from the over 100 user of Q6600 that I have collected.

As you say finding a good processor is a hit or miss and I agree, but you want to still improve your odds of finding that great OC'g processor and I am using VID as a criteria, others like yourself may choose the 'wafer number' (which I do not understand and never heard of until it was mentioned here) and the Batch#.
For me I need to know the Batch# and VID to make the decision, you cannot make the purchase decision on VID alone, because you do not know the VID value until you run CoreTemp. But with the Batch# which you can see on the side of the box or as the last line stamped on the IHS at your local Retail Store or ask when shopping online, if you know the VID value for that Batch# then that is a valuable piece of information.
Is VID the Maximum voltage that is set at full load?
Because mine goes as high as 1.24v with OCCT running.
EDIT: Never mind, I ran Core Temp and the VID is 1.28. So I guess this Q6600 won't be as overclockeable as others out there?
I have one that is 1.2375 VID, it will run OCCT at 4Ghz and I can bench at 4.1Ghz. The other two are 1.325 VID, and I cant get 3.6 stable with those.

I think the only way to find out the Vid is to pop it in a mobo, I don't think they are batch or week related, it's a nice collection you made there but I think it's too theoretical mate, it will not guarantee it's the better clocker... many of the low Vids scale well ( volt/mhz ) but some are really weird and just don't behave as the previous one... and I had numerous E63/64/66/6850 and Q6600 already, it's really mostly hit and miss...Quote:

I'll have a look into ya great work you already did for us... will take some notes :up: but like you claimed not all overclocks are based on the same criteria : user, hardware used, ....
Definetaly the mobo holding ya back mate, like with the striker there are numerous FSB holes and it needs some good tweaking to get it stable most users run it succesfully with 425FSB (x8) but more is a hit and miss... get a good Intel chipset and you will be flying for sureQuote:

Initially I thought I would do the same with the Q6600, but I have found that the early 'B' as in L721B, L725B and L730B were not up to my standard for 3.6GHz. The L737B however are very good and so are some of the L737A. So here is what I have found so far the data is patchy since folks do not post everything I wish to collect.
This is for Week 37 for Q6600, I will include Batch# that known to be in existence and may have no data for it.

The spacing is a problem, so look carefully at the list and the caveat is that this is only as good as what folks post on the Web, you can choose to trust or not trust this information. Much of the information came from the extreme forum so you can search around and find the owners and ask them politely for some more info, before you make your purchasing decision.
I will try to keep going with the list ie Week 38, 39, 40 as the data becomes available.
Are there any more results with these L738B chips?
One on ebay thats tempting.

Just got my Q6600 G0 in.

My Q6600 G0 has a VID of 1.2750 and requires no less than 1.315 in bios to be able to boot and function stable at 400fsb ( *6 multi ) and would require a bios setting of 1.51v to get to 3.6Ghz ( only ran prime95 for 30mins ) i think its a bad overclocker for asking that much of a volts at 3.6Ghz
1.325 aint the end of the world, mine does just fine, been crunching 24/7 @ 100% cpu load on these settings for a long while.

Do all of you have your northbridge voltage and FSB termination voltage set to auto in your BIOS?
I can tell you 99.9% not... which mobo do you own mate ? most peeps set NB and co to manual settings as we had soem bad overvoltage history in the past with some boards (my commando heavily overvolted the NB while it was far from necesarry)Quote:

Amps required (Icc) may also be lower with lower VID CPU's, so they do run cooler/lower power/lower TDP than one with a higher VID at the same frequency/amps per core/bus speed. That's why they're better. 0.85VID is the lowest and 1.6VID is the highest possible.
But they can run cool with a low VID at stock and still be bad oc'ers and so people tend to look at Batch/Wafer to "estimate" the oc potential. The two combined help potential customers.
Just chiming in...
Q6600, L737A832,
Vid: 1.3250v
Currently @ 3.6Ghz (450x8)
vcore: 1.44375v set, 1.445v idle, 1.446 load, measured with multi-meter
(vdroop mod done on striker)
Seems stable and the temps never climb past 52C on the hottest core, 20C ambient, on water.
Pushing for more once this 680i proves to be stable over a week or so. Need a good fall-back point.
ZeroOne do you have a screenie of p95? showin its stable?
How do they know what vid to set.Quote:

Not fine tuned yet, but here is a quick 3hr run. 32M was a little slow but it was running at the same time as prime.Quote:

EDIT: This thing sucks. I don't want it anymore. I bet it's the board, but jesus. itll do 3.2 at 1.1v, but any higher and you need 1.3v+...it clocks like an AMD. Doesn't respond to voltage or scale whatsoever.
Give me a bit longer. I bet the vdroop is killing this thing.
Hi!
My brand new Q6600:
L737A832 VID 1.3250
3.6Ghz @ 1.45V @ Prime95 = Instant lock-up.
This thing SUCKS. :down: :mad:
FYI I have an OEM and it's VID is 1.265. Can do 3.6 but it takes about 1.4v which gets a little hot for comfort while crunching 24/7. Zerotherm Nirvana 120, ambient temp 72F.
yo! I´ve been running 3.4 for 6 month now. My VID is 1.352
3.4ghz - 8 x 425
Vcore
1.4625v in bios
1.408v idle
1.36v load
It is prime stable for 30 minutes.
Now I wanted to push it to 3.6
At 3.6ghz - 9 x 400
Vcore
1.55v in bios
idle 1.48-1.51v
1.37v load
Prime stable for 1 or 2 minutes
what´s the maximum voltage and temp for 24/7?:confused:
1.325 VID may not be the end of the world but, for most, it's much harder to get them to clock with lower voltage. My L804A (1.325 VID) takes 1.48v load for 3500 while my L723A (1.23 VID) takes 1.45v for 3800mhz.
LOL I didn't even remember making a post in this thread. I've been running 3.4Ghz @ 1.575v BIOS since I got the chip as well, the good thing is that no games can take full advantage of the chip yet so I can just leave it as it is. I think I can skip the 9300's and 9450's or whatever that new stuff is called and wait for the gen after that.
What about idle and load?Quote:

Is under 70, Yes the vdrop is about 0´5 from 1.55 in bios to 1.5 - 1.49 In windows
1.325 vid = 3.6ghz at 1.50vcore on 4 phase digital power, Under water max, speedstep and thermal control and vdroop enabled
I'm under Tt bigwater 745 with fans slowed down to 7v.
it drops to 1.4xx, I think 1.470's I can't remember exactly, I kinda gave up totally as soon as I found out it won't be stable on anything more than 3.43
I'm still on P5K SE, which I believe is 3 phase power.
Just check my post on page 1. Have pictures attached.
I've got my L738B555 12/20/07 at 3.6 with a vcore of 1.47. VID is 1.325.
Not bad man, is it 1.47 bios or on windows?Quote:
