Overclocking a Phenom IIx4 965

post #1 of 6
Thread Starter 
I'm looking to overclock my current CPU because I want that bit of a boost so that it can hold me off until I get a upgrade in the coming months. I know they are dozen of threads about this matter but I wanted to make my own because I feel mine is a bit specific. I want to overclock it to about 3.8 (Nothing to big) on stock cooling because my H50 crapped out a few weeks ago and don't want to get a new cooler if I'm going to upgrade soon. How would I go about the OC of this CPU with the mobo I have and is it feasible to do so under stock cooling. Thank you.

EDIT: Oh yeah is it worth it for me to unlock my 6950, are there any negatives like heating?

I would say you cannot achieve that with stock cooling. Unless AMD has done something radical in the past year since I bought my CPU, the stock cooler is woefully inadequate. In fact I was getting almost 60C load temps at stock clocks before I ditched it. Any voltage increase (which you'll need to do for 3.8) will quickly overpower the stock cooler.

I am assuming you have a C3 965. I do not recommend overclocking on a stock cooler but 3.8 on a c3 might be possible. The max temps for a Phenom II is 62c so as long as your below ~58c on full load then you're fine. As for the overclocking process, you should really do your research before starting. Here are a couple great guides that you need to check out before you start.

Unlock the 6950 if you want, it can be done no problem on that stock cooler, your temps will be fine.

You're probably right but if he has a nice chip he can do it.

You should still buy a better HSF, if you plan on upgrading you can still transfer your HSF to your new setup, just keep the intel brackets if you plan on going intel.

Hmmm I wouldn't recommend it on your board. On the main site, Asus lists it supporting 140w CPU's but everyone knows its a 95w board. And unless its the nice heat pipe cooler that your using overclocking your 965 would result in failure.

You really should at least get some VRM cooling on there before starting, otherwise the OC may not even work properly. With proper VRM cooling it should OC just fine and support the proc.
