q6600 GO overclocking to 3.4ghz, what voltage?

MumboJumbo · 17 Apr 2009 at 16:12

Hey well im pretty confident my motherboard is a very unstable overclocker as it was playign me up from the start. Since fixing other issues with my pc i desided to overclock it again from 2ghz, as i had orginaly underclocked to try help stability.

Now i find my self trying to hit 3.4ghz again and so far its only managed prime 95 (still runnign has been about 20minutes so far) at a voltage of 1.47V.

This seems miles too high to me but 1.45v caused it to crash within minutes.

Ive upped the MCH to 1.27v and my ram is stable on 2.1v. Everest says my cpu voltage is 1.325v, but surely my voltage drop cant be that bad?

What other programs could i use to check this, cpuz doesn;'t appear to say what voltage im puttig through. I thought it did but its been years since i overclocked and i forget now lol.

Thanks.

:EDIT:

Im thinkign im lookign at the wrong thing on everest and that 1.325v is a stock setting, but i cant see where else to look.

ok i just noticed that thread 4 had stoped running due to an error. Am i to presume this counts as not enough voltage ? or maybe my mobo just really cant do it coz well its poop lol.

:EDIt:

just ran it a second time andn 4th core faield again.

Yeah you need to look at other ppl's OC's to get an idea of what is possible, yep more volts, just take volts up slightly untill prime is stable.
It might not need more cpu core volts try NB @ 1.45v and SB @1.5 to 1.55.

Keep an eye on your temps.....Keep the NB/SB under 58c.

I'm running my Q6600 @ 3.6Ghz and the Ram @ 1600Mhz.

There's plenty of info on overclocking these CPU's on the forum.

CPU-z tells you the voltage...

1.47 is very high for 3.4GHz, are your temps good? Use RealTemp to monitor those.

When did you buy this? Q6600 used to clock great but later batches are not as good as the first ones supposingly (and oddly enough )

Yeah i know its very high. Its not the cpu i think its my mobo as i know its a flaky one. Im getting abouyt 73 degrees at load. which is fine i gues but not what i want and the 4th core doesn't pass round off checking on prime. Its an old one, should be a good overclocker. If cpu-z is telling me the voltage then i have a huge v drop

Apart from the vDrop is there anything else wrong with the motherboard? Could you RMA it or is it out of warranty? Sounds like you are unlucky... a relatively cheap P35 could very well clock better than that ~_^

My Q6600 3.4GHz BIOS v 1.45v

OLDPHART · 18 Apr 2009 at 14:03

My O/C setting’s for Q6600 @ 3.2GHz (EP45 DS5 MOBO)
Cpu host clock – ENABLED / Cpu clock ratio – 8x / Cpu host frequency – 400 / Pci express frequency - 101 / Performance enhance – standard / System memory multi – 2.00D / Memory Setting’s - Dram timing (spd) - manual / Cass latency timing – 5 / trcd – 5 / trp – 5 / Tras – 18 / Cpu Vcore (Stock VID 1.3250v @2.400GHz) because of volt drop set Cpu Vcore 1.37500v but reads VID 1.330v DUE TO VOLT DROP / Dram voltage – 2.080v. They are the only setting’s I’ve changed in the bios, been solid since August 08, temps never went over 60c last summer, using ACFPro 7, Hope this helps.
