A stable overclock? Spec inside

Sega Mega Dave · 19 Mar 2011 at 19:25

Hi Guys,

Just upgraded to a new system with the following spec:

i7 2600k 3.4ghz
Corsair Vengeance 8gb ram
Gigabyte P67A-UD5 motherboard
MSI Geforce GTX580
Corsair Hydro H70
Corsair 850w Modular power supply

What would be a stable 24/7 clock and how do i go about setting it? Is it just a matter of increasing the multiplier and upping the voltage?

If there are other settings to change what would they be?

I'm hoping to aim for about 4.6ghz with this what voltage am i looking to aim for?

For some reason i can't search without it crashing and i'm also struggling to find some info on voltages etc....

Any help appreciated and sorry if this has been asked time and time again.

Thanks,
Dave

Are you saying the pc crashes at stock speeds? If so, best deal with this before trying overclock. Have you set "default" in bios?

Default bios first then make sure you RAM is set up correctly I.e. timings/voltage. Might be an idea to burn an ISO of Memtest86 and run that over night

Sorry i meant when trying use the search function on here it was crashing so couldn't look up if this question had been asked before.

It runs fine and dandy on stock speeds.

Just really looking to see what settings apart from the ram timings/voltage etc... do i need set to get about 4.6/4.8.

I had an i5 previously and had that clocked easy enough.

Basically apart from ram is it a case of setting the multiplier with these new 2600ks to say 46/48 then upping the voltage a little?

If so what voltage are we talking to run at those speeds, i know each cpu is different but a rough guide would be great as dont want to cook it with over voltage.

Would say 1.28v be enough with multiplier at 46/48?

Sorry for all the questions...

Forget all these new fancy graphics and high AA settings, give me a sega mega drive and a copy of road rash/streets of rage any day

Start from 1.3 work way up or down every chip clocks different

As above 1.3 - 1.35 ish I'm in the 1.34 volts for 4.6.

AS above also.

I used Asus overclocker so my vcore varies with speed & load but I have monitored it whilst stress testing. maximum vcore is 1.32v for 4.5Ghz.

Cheers guys...

So is it just a matter of turning up the multiplier and upping the volts a bit?

If not what else is worth tuning off or on etc...

Anything over 4.5 I had to turn off c3 and 6 states. C1 and speedstep are fine. I also found my stable volts by setting it manually (which meant that at idle volts did not reduce) then used Dvid. I think the bpis sets 1.37 for 4.5, minus .030, with vdrop 1.33 and vdroop to 1.308 under load.
