*Official Retail G0 Q6600 Overclocking Thread*

[moons_shadow]

Hi, this might sound like a dumb question but are the voltages people are reporting the voltage that they set in the bios or the voltage that CPU-z reports? I'm asking because I'm having some pretty severe vdroop on my pk5 deluxe. I get about 0.07 V drop idle and 0.122 V drop under load. I'm still kind of inexperienced at this so I'm still figuring this out.

If your curious at what I'm doing to it now currently I'm stress testing it at 388x9 at 1.45 in the bios (so the Vcore in cpu-z is 1.328)
temps between 52~55C

But I've only been running it Prime95 for about 20 minutes so far.

Also who has used the pencil mod on a P5K deluxe and got good results with it? It seems like lots of people are reporting not needing a vdroop mod, I guess I'm just unlucky.

Most people report both Bios voltage and load/real voltage. That vdroop seems severe. Do you have the Voltage Damper enabled? What version of CPU-Z are you using. The newest vesion 1.41 reports vcore very well, the earlier versions were somewhat unreliable for vcore. You can use AI Suite or PC Probe to give you a good idea of what the voltage is loaded and unloaded.

Yeah, I have vcore 1.41. Although tonight I learned a lesson Auto does not necessarily mean "enabled". I tried the pencil mod it changed my total Vdroop to .092 from .122. I enable the Voltage Damper and it goes from 0.092 to .02 . So now I'm running at 1.425 bios 1.400 Prime95 @ 400x9. I had it going for an hour but the RAM was getting too hot so I lowered the RAM voltage and restarted. Wish me luck. Hopefully by the time I wake up this morning I will have something concrete to post about.

Hey, its been a while...

Picked up a Q6600 G0 L720B058 from Scan the other week and have been running it at 1.38v for 3.5GHz on my Commando so far, but the temps were on the high side:- 72c at full load under a Tuniq Tower 120.

389 x 9 (3.5GHz)
Vcore 1.38v
Idle 39c
Loaded Small FFT's 72c


Anyway, obviously temps were holding me back quite a bit so I Lapped the Q6600 and didn't see any noticeable improvement so I bit the bullet and bought my first watercooling setup:-
D-Tek Fuzion
PA120.3 + Shroud + Nexus Fans
MCW30 Chipset block
1/2" Tygon R3603 tubing
Laing DDC w/ Petra's DDCT-01s Top Combo

With the same ambient I've seen a 16-17c temperature drop when running at the same bios settings and the AS-5 has yet to settle in, I can't believe it made that much of an improvement over the Lapped Tuniq and the whole setup runs much much quieter than the Tuniq... Needless to say I'm pretty impressed!

389 x 9 (3.5GHz)
Vcore 1.38v
Idle 34c
Loaded Small FFT's 56c



I'm going to keep looking for the optimal balance of temps/Mhz so I'll post any interesting results I get when I get them.

Got my Go today 726B 1,23 vid. WC at 3,6Ghz Prime stabel 1,36v. Should be able to get it to 3,8 but that i will test later.

Alright I've finished my first successful overclock attempt. Here are the specs

Batch L723A964
3510 Mhz (390.1 x 9)
BIOS 1.425V Windows 1.416V IDLE 1.400
Idle
42-42-35-40
Load
66-66-58-58

This still seems pretty hot to me, especially since I'm watercooling with a D-Tek Fuzion waterblock and PA 120.2 radiator. It makes me think that I might have improperly mounted the waterblock (I've heard overtightening causes concave bowing) and I'm tempted to lap the processor. But I'd like some feedback first. It might be worth noting that my AS-5 has not cured yet and I know that will give me a drop of a few degrees. Comments?
