I'm running Prime95 Blend Test - when will it be done?

southpark2033 · Oct 12, 2008

Do I just run it until I stop it or is there a "proper" time to stop it or will it stop itself? It says it passed a self-test (1024k) what does that mean?

Whats the best way to use this thing: 4 hours? 24hours? Oh and it's running 2 threads for both my cores so I understand that much.

It will continue running until it stops due to instability or when you stop it. If you run prime 25.6 it will automatically create a thread for each core.

Run for 3 to 24 hours to determine stability... thats what its for to TEST stability of your CPU and Memory.

I personally run for 12 hours because thats usually how long my computer is on for.

if you can run it 24+ hrs stable just means you have a rock-solid OC if your running the "blend" test in vista though it can be a pain to use your computer. i usually just go with a 24hr large FFT run to test for FSB/cpu stability and then use Memtest for a overnight run it can usually do a 900% run over that time, to test for memory stability.

I always test it for longer than the hardest task I will ever ask of my computer. For example, the hardest thing my computer does is video editing work and big render jobs take 4 hours. After effects work is very memory intensive so I make sure my ram is super stable. With that in mind, if I am 8 hours Prime Stable then I am fairly sure nothing will ever crash my computer during normal use. I guess the longer you test for the better.

12~18hours is a good stability benchmark.

+1 12 hours. Lots of people agree that a 24hr blend is the trick, but hard to see a diff from where I'm sitting.

first i set my memory ratio to 1:1, so i kno my memory isnt holding me back. i use the large fft to test cpu/fsb and after i find the highest stable cpu OC, i start to OC my memory and test using memtest.

12 hours is the winrar

SkiBum1207 · Oct 14, 2008

just remember NO MATTER how long you test, it still could be unstable, just the longer you run it, the probability of failure decreases, but i agree 8-24 hrs depending how paranoid/mission critical your computer is

I run small fft overnight to stress the CPU. Then I run OOCT2.0 custom 2hr RAM test to stress the NB/RAM (very important on quads). I also do memtest86+ for at least 2 passes.

Then I like to drop my FSB 5MHz (or close to that) to give myself some cushion.
