[M5A99X Evo r2]

I have an FX-6300 running at 4.6Ghz on an Asus M5A99X Evo II.

Everything's been thoroughly tested and seemed fine for weeks until recently I needed to RAR some files and every time I tried resulted in a complete OS freeze.

Long story short, I left most settings at auto in the BIOS and the one which fixed the problem was in the DIGI+ POWER section.

Manually setting the lowest value which worked in the CPU CURRENT field, in my case 120%.

Just thought I'd share this finding, if like me you overclock carefully and were stumped by a similar problem and didn't want to max all BIOS settings.

Pro Tip: When over clocking, never leave anything that directly affects OC'ing to auto. Always fine tune as you go. Pretty much OC'Ing 101 friend lol.

Plus, always stress test with something like prime95 and OCCT before calling it stable. I say more likely than not, OP's overclock is still not fully stable going by what he wrote.

Don't jump to conclusions.

Prime95 ran for hours without error in all 3 preset torture modes, I say all 3 because one creates max heat, one shows max voltage and the other a bit of everything that can show up errors even if none were encountered in each of the previous types of test, despite drawing less voltage and creating less heat.

I must conclude that WinRAR and the particular files I was compressing just highlighted a weakness somewhere that Prime95 did not.

No previous compressions with WinRAR showed any errors never mind totally locking up the OS.

Other than that everything is 100% stable for all uses.

So what was it? Digi power or WinRAR? I should have said this sooner but stop using prime95. It's an old method of stress testing that doesn't use all new instruction sets. Use a various combinations on stress test software to determine if your overclock is save.

You should have run that for 48 hours.

thats a little overkill. 24 is more than enough

It's either 24 or 48. Thats what i saw on results posted in a topic on here,overclock.net . Half was 24, the either half of the people ran 48 hours to say their overclock was stable.
I am a "guarantee" guy so i picked 48.
