Overclocking Phenom II 965 Black Edition

post #1 of 12
Thread Starter 
My rig consists of
AMD Phenom II 965 Black Edition
AsRock Extreme 3 870 mobo
Sapphire Radeon HD 7950 OC'd Edition
8GB G.Skill Ripjaws
Win 7 64-bit


Currently im sitting at 3.8Ghz with 1.47V and i blue screen under heavy loads. My temps usually stay in mid to high 20's when idle,and mid-high 50's under heavy load. my goal is to get my cpu to 4.0Ghz. i hear some people dont have to raise their voltages all too high,but i'm wondering if my other hardware plays a part in that. 1.55V seems to be the maximum most people will go when it comes to voltages. if i bump up to 4.0Ghz,would it hurt to crank my voltages to near max,and hope it stays stable? or should i just continue to bump up the voltage a tick everytime i blue screen? (New to overclocking,so be gentle!) tongue.gif

Going to max acceptable (to you) voltage and then backing it off once you find the max OC, is a common method of overclocking. Knowing the limits of the board is not a bad thing and the built-in safeguards should prevent you from damaging anything. Just keep an eye on temps.

whats a reasonable/safe temp to go for? i try to keep it below 60 under heavy load,but at 3.8Ghz and 1.47V it was getting to about 60,but i cant really say for sure cuz i cant stay under heavy load for too long before i blue screen. so if i up the voltage,i may have cooling problems,which i shouldnt. I've got a good heatsink/fan for my CPU,not sure what brand it is,but my temps get incredibly low when idle after i put it in,and im rocking a ton of fans. see Rosewill Thor v2 case. have amazing airflow,but i dont know if going that high requires liquid cooling to keep the temps low as possible

You are getting close to what most people consider the high point for that chip. I wouldn't let it get past 65 consistently and even then, I would weigh whether that extra heat/decreased life is worth the bump in speed.

is there a possiblity that my cpu is bottlenecking my gpu at stock speeds? friend of mine mentioned it might be,but wasnt exactly sure

Alright thanks, how much of a speed increase do you think i'd get,going from 3.4 to 4ghz? if my cpu is just fine at stock speeds,then im not gonna risk the extra heat over little performance gain

In CPU-demanding games, yes. In GPU-demanding games, no.

If you're BSOD'ing at heavy load, you're nowhere near stable. Time to start over. Time to check things, like settings in BIOS, cooling solution, VRM temps, etc. Back to basics.

3.4Ghz to 4Ghz is more than a 'noticeable' speed increase - both visually and in benchmarking. It's worth it if you can keep it cool and more importantly, stable.

It's your motherboard..It can't handle the voltage the cpu wants to pull.Here..have a read of this stuff smile.gif

My cooling should be fine. good heatsink for my cpu,a top 240mm fan,a side 240mm fan,a front 240mm fan,and a 140mm rear exhaust fan. no wires are really visible,all hidden behind the mobo. I monitor my temps frequently and at stock speeds,highest my cpu has gotten was 56c during heavy load. but by having to increase the voltages to get my 4Ghz mark,im afraid it may go way over that probably within minutes of booting up a game.

When i was at 3.8Ghz with 1.47V my cpu idle temps was low 40's,with a high of 59 during load. is there anyway to know an estimate of how much the temp will go up depending on the voltage? If i got to get my voltage up to 1.5 to become stable then i'm afraid my cooling may not be enough

@Schmuckley Thats what i was afraid of. Thanks for the links,i'll look through those now! smile.gif
