fx8320e overclocking problem

[lebron]

Hi Guys,

 

For the past few days I have been trying to overclock my cpu, but only getting poor results. Hopefully you guys can help me out or tell me what went wrong.

 

So here I was trying to OC my fx8320e, which I read can easily OC from 3.5GHz to 4.0, many reported a stable 4.5ghz OC.

 

I increased my multiplier little by little, disabled turbo, test it with prime95 and all, I increased the cpu voltage little by little and retry if I get BSOD.

 

At last I couldn't get a higher stable clock than 3.7GHz at 1.3V, which is a really high voltage at this clock from I've read. But if I lower the voltage it started to crash.

 

Temp isn't a problem since the max temp I got at full load is 40C (I have a aio cooler).

 

So what did I do wrong? Or am I just unlucky and got a shitty cpu?

 

Here are my specs:

cpu: fx8320e

gpu:gigabyte gtx 970 g1

mobo: ASRock fatal1ty 970

ram: Kingston hyperx fury 2*4gb

PSU: Thermaltake Smart 650W

cpu cooler: corsair h55 quiet edition

 

Any help would be appreciated.

 

Cheers

1.3v leaves you with .2v headroom, I wouldn't worry about it too much (although I wouldn't go above 1.48V unless you have dope cooling)

 

I'd try going for a higher clock since you have a lot of voltage to play with

yeah that's what I thought. But when I increase voltage and clock (say 1.35V and 3.8GHz) it crashes during prime95.

ooh. Have you tried changing load line calibration? You may have some bad vdroop (really hurt my FX overclocking)

Yay! It appeared that my problem is solved.

 

I didn't change my llc, but when I was looking for llc settings in BIOS (couldn't find it), I realized I have been using the "cpu oc mode" to OC.

 

After changing it back to "manual mode", I applied the same clock/voltage as before, and Voila! I got a stable 4.2Ghz at 1.38V. Ran prime95 and all looks good.

 

I have no idea why one mode works and the other doesn't, but I'm not complaining.

 

Thanks for the help!

New trouble arises.

 

After my OC my gpu load keeps fluctuating widely, causing a very unstable fps (when I was playing witcher3). It has happened before (fluctuate gpu load after cpu OC), any idea why? Sometimes restarting my computer fix it, which seems very weird to me.

Check your clock speed while the game is running. Sometimes OC's will dip down :c

Computer has been stable for a day now. After I restarted it everything is back to normal! I guess the old "turning it off and back on again" does solve problems sometimes.
