you can check out my L804A a few posts up, 3.2ghz at 1.32v is ok imo, maybe i will see what it takes to get up to 3.6ghz.
well.. just tried for 400x9 with 1.46v load and it was not OCCT stable. I don't feel like trying higher with this MB
dangit GEN you're making me fearful that my l804 is gonna suck! I guess I can always go rev isioned 45nm quad :P
Pacha, those are some nice shots of before- and after-lapping. One thing I noticed on your PCB code, it starts with 2L7 instead of 357 like we see here in the U.S. most recently - I have yet seen any L80x with the 2L7 code, which used be shown on those glorious batches of the year 2007 production. So it bodes well for you.
As a data point, I just finished testing a L804A Q6600 which inevitably sucks. The VID is 1.325v and runs quite cool under 3.0GHz. It only needs 1.175v for 2.8GHz OCCT 2hrs stable, T < 47C on all 4 cores with my lapped Big Typhoon. Unfortunately, it requires 1.325v to stabilize 3.2GHz (all cores < 58C), and a whopping 1.425v for 3.4GHz. Didn't want to go even higher as I wasn't inspired at all. The chip was returned back to the store.
Keep us posted with your results!
1.325 bios volts or loaded volts ?
Sorry, all the volts in my last post mean BIOS settings. And I enabled the load line calibration.

Just to add some info on what you were answered, on points 1 to 3:
Opposed to B3 old steppings, with G0, you'll ususally be limited by temperature before exceeding vcore intel limits of 1.50v. But, be careful, when you enable loadline calibration on any vdroop compensation, you actually overshoot usually by up to 0.09-0.1v. If we accept a normal envelope set by intel as 5%, and consider 10% to be a safe margin, these 65nm chips wouldn't die so fast up to 1.5v +10% : 1.65v. So, even with vdroop bypass techniques enabled, you'd be safe with a bios setting of 1.55 vcore.
About the temp, I'd monitor with coretemp. Personally, I feel anything higher than 69°C with Prime95 small FFT is too hot. But, 69°C in Prime95 small FFT won't exceed 60°C in most usual daily tasks, even video encoding
As of 4GHz, forget it on air for 24/7 unless you are at constant 10°C ambiant. On water, only few selected and valued chips will do it, so forget it too. 3.6GHz is sweet spot, 3.8 GHz on many low vid L7xx batches and 3.9GHz on some L7xx batches with quality motherboards (P35 for full stability)
My chip can do 3.9GHz stable P95 small FFT at 1.47v. For memory bandwidth issues, I opted for 3.84GHz
This is only when you exceed 1.50v to 1.55v on the vcore for a quadcore on high quality PWM motherboards. On lower end models, it will be a problem as you exceed 1.45v, sometimes before

ah thanks, as i suspected 1.46v was just enough for SPI 1m (with 4 threads) stability but failed OCCT almost instantly. When/If the 680i MB dies i will probably replace the board and run it 1.5v or so i'm assuming mine will require that as well. 1.5v on 4phase power is just too much.
@jonny
even with 1.376v load on my P5K-E i will not use load line calibration (needs 1.4v bios), even without it enabled (1.456v bios) sometimes i get a reported 1.6v overshoot when exiting OCCT (whether it's accurate or not). vdroop is a safety feature and i would reccommend not using vdroop/LLC for 24/7 as well.

Hey guys,
I am looking for a store who is known to carry low VID q6600's. I know it's a crap shoot and not all stores are willing to take the time to show this stat, but is there anyone out there who will let me hand pick one (online) based on VID? My buddy just got a newer batch q6600 as well and it had a 1.325v VID. Mine is 1.275v. 865pe's VID is something that I would like to jump on (VİD 1.2125 seems really low)...
Thanks!

The problem is, the VID voltage is not on the package. you really don't know until you install it and fire it up.
The best Q6600's are the one that start with L7. You need to find a store that still has them.
My lapped Q6600 GO (L726B397) with a default vcore of 1.224v's, only requires 1.392v's to make 3.6GHz stable.

I have it set to 1.4-1.55v depending on...my mood, really
I have never had issues with the vNB with 2 or 4 sticks.
I also went a step further and removed the Chipset Heatsinks, cleaned the factory crappy putty off, and put Arctic Silver Ceramique on the NB, SB and Mosfets that are covered. I also did the same thing to the Heatsink that is above he CPU at the top of the motherboard, plus I have a 120mm fan blowing down on the RAM and NB. The NB is not even warm to the touch.
That might explain why I have virtually no NB issues with heat.

Great, nice to hear if I ever decide to go with 4Gb RAM
The mosfets are better with the thermal pad, as the default heatsink can cause loose contact. If you kept the pad, adding a second thermal interface material (AS5) with the pad is not a good idea, in my opinion as you add interfaces, while pads assume a better contact than paste but are less conductive than a compound.
As of the heatsink above the CPU, it is for the other 4 mosfets.
I'm also sure that people taking care to cooling the motherboard and reseating the default heatsinks will have better performances by far. For stock radiators, you also have a very good overclock on a Q6600 + 4Gb Ram on air, as I removed them all and replaced with thermal righ heatsinks

not sure I follow you. I took off the thermal pads on all heatsinks and added the nonconductive Arctic Silver Ceramique, not added to the thermal pads. The Arctic Silver Ceramique makes great contact with the mosfets as I test fitted them, and the footprint "smear" was great.
Correct me if I am misunderstanding you.
Thanks!

Humm.. so you removed the thermal pads
The mosfets heatsinks are covering 4 PWM each. This will cause in all cases a loose contact sometimes on some mosfets, despite the tightening of the push-pins. This is due to 4 things:
- The PWM surfaces are never even at a same level. Making that will need very expensive manufacturing process and is useless because of the bending of PCB. This first issue is the most important and impossible to correct, unless you lap evenly all mosfets with a glass
- The mb PCB is not hard, it bends, always... less than 1mm, but it bends
- Fixing of the heatsink is made by two push-pins on the extremities only, so impossible to solder to middle of the heatsink when the PCB bends
- Finally, ASUS heatsinks are really light aluminium without any surface polishing or special care.
It's not without a reason that all reliable third party manufactures of optional mosfets cooling kits recommand thermal pads for cooling mosfets.
This is also the case on VGA cards when cooling memory chips: you need either separate heatsinks per module, or the use of a thermal pad for many modules under the same heatsink because of the always uneven surface between two chips
Hope you understand better now what I meant
