what settings for prime95?

[BrianHanna]

After battling with it for a while, i finally got my computer to boot with the following settings



so, how long should i run prime95, and at what settings ( figure at least 12 hours, but i'm not sure about the settings)

[3.0charlie]

Simply let it rip, "Blend" settings. 12 hours would be fine for me.

I usually use Linx for a quick analysis for the correct voltage. Run 3 runs at max memory and insure that each run passes with gflops greater than the previous.

Then continue do a 20 runs of linx (1 to 1 1/2 hrs), once pass run overnight tests. Either Prime95 blend or 100 Linx runs.

BTW those are great voltages for 4.2 if that is stable.

Good luck

I find that small FFTs will give me BSODs sooner than blend tests, but each to their own. Blend tests are probably much more thorough, but I just want to know if I'll get blue screens or not.

Ehat cooling ? If your on stock your going to have heating isues BIG TIME.

[enaberif]

blend works more on memory.
smallfft works better on cpu

He's on a aftermarket cooler.

Noctua NH-U12P which is pretty decent.

Ya didint see it at first. It is still were I expect problem on like 24h run on prime95.

So "Small FFTs" is the most intensive CPU test in Prime 95? I want to use the most intensive test to give me the confidence that my overclock is indeed stable.

I suppose if it is stable after 24 hours or so, I can use blend and will blend stress out the motherboard in addition to the RAM? I also want to make sure the RAM is tested for stability as well.

Newest version is 27.7 build 2 stresses the instruction set avx more
