Hello.

As im looking at upgrading my GPU from the GTX460 to a 660ti or something similar I was told to overclock my cpu from 3.4ghz to 4.0ghz as at 3.4ghz it will bottleneck any good graphics card.

Ive just set it to [x20] which is 4.0Ghz. However I couldn't find where to up the voltage to "1.5250" so I restarted the system anyway and it blue screened. It seems to be ok now its back to 3.4Ghz for the time being.

I noticed in the BIOS there is some kind of overclock boost setup. Is it worth going through this to overclock my CPU? Maybe use programs instead of doing it through the BIOS so I can edit the voltage?

Thanks

EDIT:

Found out how to change the voltage. It is the CPU voltage I need to up isn't it? I did see a youtube video and he upped it to 1.5250 but it seems I can't get it bang on that number. Any number around this shows up in red.

which phenom is it? 1.525v is loads of voltage for most cpu's.

Phenom II x4 965. I have it set to one under 1.525v at the moment.
 
i wounld go above 1.5v unless you have a very good cooler. you need to try and go up in stages not set the multiplier to 20 straight away. around 3.8ghz should be a decent enough oc to run with a 660ti and i don't think it will hold it up at all. even at stock speed, but a bit of extra speed should give it a tiny bit of a boost.
 
Which phenom, and which stepping is it.

My 955BE does 4ghz with 1.45vcore, used to do it with 1.4125v before it was abused with 1.7v.

I have the noctua nh-d14 cooler.

Should I bring the voltage down to 1.4v then and see how I get on?
 
The NH-D14 will cool a phenom II sufficiently even at 1.55v (max safe)

To start with set Ht link, northbridge, memory speed, ram timings and voltages manually.

Start with 19x multi with 1.5v. Some will say run prime to test stability, I'd personally play a few games. If that's stable up it to 20x multi and retest, if it's unstable go up to 1.525v but male sure temps don't exceed 55'c. If 1.5v is unstable at 3.8 with 1.5v try again.

Try those then post back.
 
yup that's good advice from frozen. I have my 965 running a 4ghz right now on 1.42v 20x multiplier, fsp 200mhz. for me that's a very stable overclock but not all can expect to get the same result. What motherboard are you using out interest?

that might be you problem to be honest. I hit a brick wall when overclocking on my old am2+ mobo and ddr2 ram. I just couldn't get passed 3.8Ghz until I upgraded

Temps seem to be fine at the moment :) I was tempted to upgrade the board so I can run SLI but then I thought I may as well just put my money in to one card.
