Tips on overclocking the Q6700

post #1 of 8
Thread Starter 
I have a Q6700 with a VID of 1.26v. I've been fiddling with the clocks for about a week now, and I'm trying to get it stable at 3.6GHz (I was under the impression that the Q6700 could do that relatively easily, was I wrong?).

Right now I'm running prime with a Vcore of around 1.42v, and VTT a little bit below that. My temps hit about 60c max, according to RealTemp.

So is there anything I can do besides pump the vcore here? Or is 3.6 going to be my only hope? Also, does a load temp of 60c make sense at this voltage?

Any tips would be appreciated, thanks.

Where's your NB at? Do you really have 8GB of RAM like it says in your Sig? If so you'll need lots of voltage to that. 60 also seems a little high, do you have good airflow in your case and good cable management?

Edit: For 65nm chips you should be using Core Temp instead.

Make sure you aren't overclocking your ram, Also try removing 2 sticks of ram as 8 gigs might be a bit much for your NB to handle at higher fsb with a Quad.

Is your q6700 a G0? If not a B3 may not OC that high.

I dont have experience with your board but try raising your NB volts as well.

1.42v before or after vdroop? My q6600 needs 1.42 real voltage to do 3.6, bios is set to 1.45v to account for vdroop.

More RAM sticks = more required NB voltage = lower OC ceiling.

You should also stay under 58c if you have a B3, and 70c if you have a G0.

Also, use Core Temp to monitor temps.

I do have 8gb of RAM, which is on a large divider right now while I test the CPU.

The 1.42v is the BIOS reading.

I guess I'll download coretemp now rather than realtemp and see how I do.

Core Temp should be the more correct one, could you post the difference please?

Difference is 5c. Core Temp has the Tj Max set to 100c, while Real Temp has it set to 95c.

Hi all

I have a asus p5k3 board and a newly aquired Q6700
I am stable (2 hour occt and 25 hour prime large fft) with these settings
I also have it stable a 10x360 with the same vcore .
Also the asus has a load line calibration enabled to get a more stable vcore ,
so 1.3875 comes in at 1.38 ...
if this is disabled then you would need about 1.40vcore to achieve 1.38v (vdroop)

<edit> VID = 1.2625 <edit>
