Overclocking help

post #1 of 10
Thread Starter 
So, i'm doin' some overclocking, and the only result i can see in games, is that it crashes after ~30 seconds. "Well, maybe you shouldn't be overclocking that CPU", you might say, and that's just the problem. When doing stability tests (100% load, 15 minutes) i get nothing. The problem occurs when playing games, the game just gives me a jittery screen with random colours and then restarts. It does sound like my graphics card, being a flashed 6950 and all, but why do i only get it when i OC? Also, firefox has started to lag behind when i'm typing, generally a 2 seconds lag whereas the everything freezes (the stuff i type still gets typed, but still).


My current setup. I feel as if a 965 BE should be able to handle way more abuse than just a sloppy 19x multiplier?

its your graphic card not the CPU

Mmmmmight need the rest of your system's details. Fill out your system info...?

you need to sort out your GPU's bios.... sounds like everything has gone to pot

Other info:
Mobo: MSI 870a-54a
Processor: Phenom2 965 BE
Video card: PC HD6950
PSU: Corsair 750w
RAM: Corsair 4gb 1600 mhZ (x2)

CPU cooler: Zalman... something, quite large aircooler with heatsinks.

I dont think that it is the graphics card, seeing as i only get this problem when i OC the processor. Is 1.340v sufficient to run it at that multiplier? Should i go back to the stock multiplier and rise the bus speed?

what is you CPU/NB voltage ?
RAM voltage and timming ?
try go 1.37V on you Vcore and run your game and see if to works fine if it doesn't try 1.4V if it still crashes then the problem will be 100% NOT your CPU

I tried it again, using 1.340v this time, and no crashing. Thanks for your help, i dont think that i'll go higher, at least not right now.

15 minutes of stress testing is not enough to declare your rig stable. I've seen recommendations from 4-24 hrs. I would think 8+ would be good for a final clock.

I was going to suggest to make sure your memory clocks are right, but that's not a problem when overclocking a black edition CPU.

Check your temps, what PSU are you using, and are BOTH the power cables hooked up to your card?

Not CPU if it freezes randomly but not on stability tests. Might be RAM or CPU-NB. (depending on what stability test you use, i.e. if small FFT then it's definitely not CPU)
But you should really not be overclocking a 125W 965 on that motherboard. In fact, you should be underclocking/undervolting. MSI motherboard + 4+1 power phase + no mosfet heatsinks + CPU tower heatsink + 125W CPU + overclock = instant death sentence. Don't make me bring out the horror stories.
