Overclocked CPU Prime95 Fail

[Rohit Jackdaw]

I have an AMD FX 8320 at 4.2 Ghz. Mobo is an ASRock Fatality 990FX Killer. Temps max out at 60c except Kombustor which takes it to 64c. While running Prime95 Blend at 60c after 45 minutes two workers failed. I ran memtest86 for 2 hours and it reported no errors. Voltages are at stock. Only multiplier change to 21x nothing else. Previously with an NB overclock it freezed two times. After that I resetted the NB overclock and even reinstalled windows. Even in AMD Overdrive it passed the 1 hour test. What to do now ?

Increase your voltage slightly.

[Windows98SE]

Up the voltage since it's unstable?

[Guest]

Try increasing your voltage very slightly that could fix the problem.

 

I assume no responsiblility if a few biliion transistors die

[Rohit Jackdaw]

Current is 1.3000V. Next is 1.3125V. Next is 1.3250. Which one should I ?

Do it gradually. Start with the 1.31. If it isn't stable, try 1.32. Then keep going until it is stable, or temps are too high. If the temps are too high, back off the frequency and the voltage.

the FX chips are fine up untll 1.5v just so long as you can keep it cool.

Currently at 1.3125 volts. Haven't stress tested yet.

FX chips max temp is 62c on the core and 72c on the socket, you're pretty close already, you need better cooling.

Will check that out. Current a 212x cooler.

The FX-8320 is suppose to jump to 1.425v for it's primary boost state (4.0 GHz). So you have a long way to go until you even exceeded what the chip does automatically on its own. Tho as stated, I would put better cooling on it before you attempt to overclock. What are you monitoring temps with?

[turbobooster]

I would not test it with prime95, seems like prime95 has some problems with amd, try intelburn test.

prime95 is fine for AMD and Intel(as long as adaptive voltage isn't used)

 

I would do a slight bump in voltage and raise LLC to high or very high

What about Overdrive ?

What is LLC ?

Load Line Calibration

my experience is that prime95 did not work good for my amd,s it was stable in itb, linx and any thing else, but as soon as I started prime, It fail, but that was the older prime95.

At 1.3125 volts it ran fine for about 2 hours and then I stopped the test. Temps maxed 61-62c but mostly around 59c though.

Yeah, you're going to need to get a better cooling solution. What are you using right now?

Cooler Master Hyper 212X. On gaming I think temps will further increase as case heats up. Have no games now. Will get one tomorrow. If I keep it running at 62c then will it run fine.
