Q6600 on xfx 680i

Last response: in Overclocking

Hello guys, i know this has been asked probably many times and I did search but i want to know whats best for my system if anyone out there has anything related please help me. Recently i built a new computer.

Specs:
xfx 680i LT
2- xfx 8800 gtg alpha edition (670 mhz)
2- ocz sli ready memory (2x2048 mb) 800 mhz (5-5-5-15)
800 watt PSU
500 gb hdd
thermaltake maxorb cpu cooling
Q6600 at 2.4 ghz - G0 edition

So i have clocked it to 2.7 ghz that 1200 FSb i beleive without any problems and the idle temp using coretemp is 26-35 C highest. Then when i try 2.9 ghz it crrashes and freezes. So my question is what should i do in the bios. Do i have to change voltages, enable sli memory to expert... etc. I would like to reach 3-3.2 ghz at a stable temperature. If anyone can help me out, ill try the settings out and post some pics. Thanks!

I recently read a guide and followed it, however the BIOS used in the guide was totally different in options than mines, that why i would like somoene here to help me out who has similar setup and bios than mine. I successfully OC my cpu to 3.0 ghz but still have stress test to put on it. I will post the images now so you can see. Ive seen Vcore on some bios but on mines i only see CPU voltage and FSB voltage which one is the Vcore voltage cuz i think mines to low

Just to let you kniow, q6xx and 680i dont mix. 10 % of the people manage to get a board that OCs normally. Not many, and I didnt. And you'll need VCore voltage as you up the speed of the processor. A good test is the OC standard of a CPU multiplier of x 8, FSB to 400, Memory at factory specs in sync at 800, yours is 800, so perfect, Up the NB voltage to 1.40.

It would help to know the Factory VID of your G0, core temp 0.96.1 is good at showing this. Disable speedstep and all that junk, and dont forget that its standard procedure to disable all spread spectrum options, and most processor options.

Since its not a big OC, you can always just set your VCore to 1.400 in the Bios, that isnt bad, and should get most G0's into windows at such a low speed! Would be nice to find out your VID is a low one! I have been waiting to find someone with one of the 1.1165 VID ones! man, that would kick some a$$! Mine is a 1.2625. Decent, but in the higher ones! Oh wait, it says 1.300 and you have the right version. Hmm, have you seen it fluctuate in core temp when you OC, or does it stay the same when you are at factory settings? (voltages @ 2.4)

Let me knooooowwww!

Whats up yes my VID is 1.3000 but when i overclock to 3.0 ghz the temp are : 34-28-32-28. pretty much the same if not even lower. In the bios i put the Vcore which i was told was the Cpu voltage to 1.235 i think but it says used is like 1.17 and in CPU-Z it only shows 1.192. whats wrong? also when i tried to execute files like run the installer for crysis or such it crashes.....

For 3.0 you'll prolly need more! put it at 1.3500 in the bios, that will work for 3.0 or it should, then run the tests, when they done fail, lower it a notch or two until it does fail, then up it one... you get the idea. Just to find the lowest stable voltage for your OC, if all you want is 3.0. You may find that crysis crashes anyways, as it did on my system, until I gave it one additional voltage point.

Turn off speedstep and all the usual power save features! And disable the spread spectrum junk as usual. Once you get that 3.0 stable, use it as a base set of standards to OC further. Once you start... you'll wanna keep going. For instance, Crysis appears to lose the ability to use a core at 100 % at about 3.3 ish.. and at 3.6 it uses 85% of one, max... so that appears to be where it wants a processor.

Good Luck!

Thanks Lupi i will make sure to try that out and see if its stable, how long should i let prime95 run for to see if its stable or should i use another program? when i use prime ... how do i know when its done? thanks.

Hey when i run 3dmark i get a score of 12300 or around there andyone know optimal setting on ntune to get a hgiher score ? i currently have 2 8800 gt alpha dog in sli, 2.4 ghz q6600, and 2 (2048 mb) ocz sli memory at 800. Everything is stock so is that a reasonable score for everything being stock? also anyone have any luck and tell me how to OC the 8800 gt alpha dog edition which already come oc to 670 mhz core clock.... should i oc more?

quads on nvidia chipset oc for crap. i tried 3 different nvidia chipset mobos including the 780i. it was all crap for a quad. thats the story. good luck pulling your hair out and running your quad slower than its potential. I sold my 2 8800gt cards because of this same quad problem. That cpu would do 3.6 in 5 minutes on an intel mobo.
