My pc freezes randomly after overclocking my amd fx8350, can anyone help me?

Hello there,

I've tried to overclock my amd fx8350, I've selected extreme on a lot of things in my bios and got it up to 4.83 ghz.

The cpu stays at around 50 degrees celcius when playing heavy tripple a games.
The problem is is that my pc freezes randomly when i am playing games or even watch youtube. The longsest gametime i had was about 45 minutes and the shortest was almoast a minute.
I think it might has to do something with the ammout of power the cpu gets. But i don't know anything about how much a cpu needs to have. I haven't tried to add more because i don't want to fry my gpu :(

Can somebody help me with this problem please?

Specs:
Amd fx 8350 4ghz (normal version)
Evga GTX 970 FTW (overclocked slightly)
Corsair h80i
Corsair 1000watt supply
Sabretooth 990FX R2.0
Kingston 1tb hdd
Samsung evo .. 240gb

  1. Did you run a stress tester? It sounds like your oc just isn't stable. You need to increase the core voltage in an overclock to give your cpu enough. Those CPUs turbo to 1.4 so you can safely go there without frying anything.
  2. First that oc needs stress tested using prime95 26.6 and use speedfan to watch temps. My guess is you need more voltage to get that overclock stable.
  3. what happens if you reduce the oveclock of the gpu .
  4. I am going to stress test it tomorrow, for how long should i let the torture test run?

    If i reduce it to 4.34 Ghz it doesn't freeze anymore, thats probably because it needs less power i think
  6. Yup less voltage s required the lower the over clock. If you have to increase voltage never go beyond 10%. At that point voltage could cause instant death for your CPU.
  7. Well i let prime95 run but it chrashed my pc after 20 minutes...
  8. its an unstable OC if it crashes for sure. Some times just prime95 will though error and even that is an unstable OC. I suggest moving your clock back a bit.
  9. Best answer
    to find you best overclock settings for this cpu start from factory speed and do prime 95 the rasie it one notch at the time doing the prime on each then when it start be unstable move back to the previous one that the fastest this cpu could handle .
  10. I will move my overclock back to the default settings and let prime95 run for 6 hours when im off to work. I will put the results up when its done

    That is a burn in test. Just run in for 6~12 minutes should do.
