Read Phenom II OC guide, but still don't understand how to OC

post #1 of 5
Thread Starter 
I have a 965 BE, so I just change the multiplier right? Should I also instantly change the voltage, or change it gradually? I just want it to run at 3.8GHz without any crashes, so what voltage should I put it at?

And yes, I know, I am extremely stupid for not knowing how to OC a CPU which is meant for OCing

Stay at stock voltage for now. Up the CPU Multiplier from x17 to x18 and run your choice of stability tester for 20/30 mins. This is just to test temporary stability.

If it fails, then up the voltage by one or two clicks, and then retest. Keep doing it that way.

Is there any reason to be afraid? Could something drastic happen to my CPU? And is Prime95 okay for testing if it is stable? How do I know if it is not stable?

Just up the multi to 18 run stress test for 15 mins if it passes put it to 18.5 try again keep going till you either reach your goal or crash.

If you crash up the voltage till it's stable again but keep an eye on your temps. Also don't leave the voltage on Auto. Set it to 1.375 to start.

No, no real reason to be afraid unless your temperatures go way high. For a 24/7 overclock, you want temperatures to stay under 55c.

Nothing drastic will happen to your CPU unless you let it get suuuuper hot, or if you go past 1.55v.

Yes, Prime95 is an excellent stability tester. Use the Small-FFTs when testing the CPU overclock. Since you're using the multiplier, you won't be overclocking the RAM or anything else.

Stability is a long held debate. Some people have to have 24 hrs of Prime95, 10 hrs of LinX, and be able to Fold on it for a week before they're happy with stability. Personally, I did 6 hrs Prime95 Blend on this overclock and I'm just fine with it.
