Phenom II 955: Just a little overclocking

Last response: in Overclocking

I'm not ready for extreme OC yet because i'm not comfortable messing around with RAM timing, NB, and HT frequencies yet. I've followed guides on how to do it before, but i can't get a stable build, so i would like to OC the CPU just a little bit in the meantime.

I increased the CPU multiplier to get a 3.5ghz frequency, set the FSB to 200mhz, and set the CPU voltage to 1.35. I ran prime95 for an hour and the CPU temp was 52 Celsius.

Do i need to do anything else? Basically i'd like to get the most out of my CPU with the least amount of tweaking.

1.35 seems a lil 2 high to me, but im new to overclocking and i have yet to overclock my x4 945

forgot to ask u mean u cant get a stable clock with temp? or it crashe's etc? coz if its crashing u generaly need to increase ur voltage, and then ur going to need to get a better Cooler to take the stress.

1.35 is the default voltage for the 955.

Yeah, my comp crashes when i increase the speed to 3.8ghz and tweak with other settings. I'm probably doing it wrong, that's why i need to keep it simple =)

you need to increase cpu voltage to run stable at 3.8ghz, bring it up to around 1.45-1.5

you may be able to get stable at a lower voltage than that, try 1.4 first, then raise it in increments if unsuccessful. no need running it at a higher voltage than necessary, as you'll just end up with high temps.

I'm at 3.6 Ghz, 1.4v, and NB 2200. I only ran Prime95 for 5 minutes and the CPU temp was 54 degrees. I'll do a full load test later, but i'm gaming right now and the system seems ok. Running at 46 degrees.

sounds good. yeah i would recommend prime95 for at least 4 hours, though preferably overnight.
