Update: New Question! Asus P5K-C w/ G0 Q6600 4.05 Ghz + some xtreme undervolting

Hey,

First time posting results here. :D

Setup:

G0 Q6600 L723A765 1.26250 VID w/ Thermalright Ultra 120 Extreme (stock) + Scythe S-FLEX SFF21F 12 CM
Asus P5K-C 0701 Bios w/ pencil vdroop mod
Buffalo Firestix 2x1GB Micron D9GMH DDR2-800 4-4-4-8
1xSeagate 200GB SATA + 1xWD 500GB SATA2
EVGA 8800 GTS 640MB on Dell 2407WFP-HC
Antec TruePower 2.0 550W SLI-ready

Some pics without my case:

Right now I'm working on my Antec 900 case so I am testing the ambients right now.

So far, 3.610 Ghz (401x9) stable on AIR at 1.38 vcore real (1.4250v bios).

I will be back with updates as I finish my case!

Decided to have some fun with xtreme undervolting :D.

Ambient temp is 16-17 degrees Celsius (in the basement lol).

1.1375 vcore in bios, 1.10 under load. Priming and 3dMark06 rock stable so far!

Futuremark 3D Mark 06 Compare link: http://service.futuremark.com/compare?3dm06=2695495

Okay, finally found the max stable OC at 1.10 vcore real under load.

First, I tested to see if it could run @ QX6700 speeds. No problem!

Next, tried for 3 Ghz. Ran SuperPi 1M fine but was not prime stable. :(

http://img372.imageshack.us/img372/9...idlejq5.th.jpg

Finally, found max stable overclock was @ 2.85 Ghz. This is very impressive considering this is at 1.10 vcore under load!

G0 = :up:

Okay, I think I'm done for the night.

Enjoy.

Back with some more results! ;)

Max stable FSB was 480 Mhz but I forgot to take a screen.

3.7 Ghz w/ vcore at 1.43-1.44 under load - Temps never reached above 70 degrees Celsius. This will be my new 24/7 overclock.

Idle:

Load:

4 Ghz bootable no problem! (1.52-1.54 vcore) ;)

Got another 2 GB of ram and decided to push it a little bit further. Was able to reach 3.8 Ghz PRIME stable wtih 4 GB of DDR2.

My new 24/7 :)

New question: Okay, so I basically have 3 settings to choose for my 24/7 overclock. Which one would you choose based on overall vcore, vdimm, heat, speed etc.? All three settings are using small FFT's for PRIME stability. Thanks in advance.

Setting 1:

http://img267.imageshack.us/img267/3...6600yu4.th.jpg

Cpu speed: 3.330 Ghz (370 x 9) 1.3000 vcore set in bios, 1.26 vcore real under load.
Ram: 1.8vdimm with 1:1 ratio at 4-4-4-8

Setting 2:

http://img393.imageshack.us/img393/2...mallcy6.th.jpg

Cpu speed: 3.610 Ghz (401 x 9) 1.4250 vcore set in bios, 1.38 vcore real under load.
Ram: 2.0 vdimm with 1:1 ratio at 4-4-4-8

Setting 3:

http://img267.imageshack.us/img267/7...allfwo2.th.jpg

Cpu speed: 3.699 Ghz (411 x 9) 1.4750 vcore set in bios, 1.43 vcore real under load.
Ram: 2.1 vdimm with 1:1 ratio at 4-4-4-8

I don't want to set my real vcore over 1.45 volts for 24/7 use so that is why I excluded my 3.8 Ghz setting.

Thanks guys!

Very nice result jeff :up: keep on benching ;)

Nice scores mate hope I can have such results with my upcoming Q6600...

One word of advice though never test your rig on the anti staic bag , as the static electricity is on the outside of the bag and you put it on top, I don't say it will kill ya mobo everytime you do it , but it could happen one day that it get's wasted... I was told this by an engineer

Thanks for the tip.

Good luck with your G0!

Nice clocking m8 :)

I have a L724A coming down next week! It'll be hooked under my WC set-up. I hope to hit 3.6Ghz with something around 1.40v :D

Thanks. :D

Sorry, my mistake. It's actually a L723A765.

3.6 Ghz with 1.4voltage is definitely doable!

Nice jeffyjaixx :)

I'd have a lil question for you m8!

Ok so heres the thing. My board (P5B Deluxe) is kinda weird at reading temps... Normally, Coretemp is supposed to read temps 10c (On each cores) over the CPU temps given by Asus Probe, Everest, Speedfan etc...

Well, for me, it's the opposite. Coretemp reads temps 10c (On each cores) lower than the CPU temp given by Asus Probe, Everest etc...

Last time i checked, Speedfan would read around 42c idle and Coretemp would read 31c - 32c on the cores... Now im wondering which one i should trust... I always trusted Coretemp because of the fact that it would not read temps through the mobo but directly from the CPU die.

What do you think ?

Oh and what would be the safest max temps for my upcoming Q6600 ? 70c on each cores ? (Which would mean (For me) around 80c i suppose for Speedfan)

Hmm... that's really weird. And you tried using Coretemp 0.94 for XP (0.95 for Vista?) and Everest Ultimate Edition? For me, Everest and Coretemp show very similar temps so I trust both. Also, Speedfan shows my temps as 15 degrees lower than coretemp...

IMO, I would trust Coretemp 0.94 or the latest Everest Ultimate Edition.

What vmch you use for 480fsb? You test fsb on a duo?

Yeah both (94 and 95) Coretemp shows the same temps. Speedfan, Asus Probe and Everest all reads the same CPU temp for the cores. Speedfan and Everest reads the same temps as Coretemp for cores... It looks to me that the CPU temps that are dead through the mobo are wrong.

Nope, on a quad. I used AUTO for vmch.

I say setting 2.

PS: Is it me or are you using Windows 98 lol If it's XP, you need to get some nice themes! PM me if you want, i have some killer ones that im willing to share with you :)

Nice work...rarely see extreme undervolting threads :p:

I actually get close to that with my B3 on the P5K Deluxe.....1/10th volt higher.

Okay, thanks!

Oh, I have Windows Classic theme on because I decided to use XP only for games while using Vista for all my other stuff. So I'm going to customize Vista just for its killer looks :D

I wouldn't mind getting some killer themes though ;) YGPM.

Thanks haha.

Which setting did you get close to? The first one? Very nice then. :)

nice results jeffyjai
i have been doing the same thing with my q6600 and asus striker on stock HSF
i have got the volt down to 1.100v in bios @ stock clock
but my corsair HX620w started to make buzz sound
very annoying ga
does ur power supply do the same when you undervolt?
thanks in advance

btw very nice styling with your pics
