Quick question about load testing with prime95

[RiposoEterno]

I keep reading places that people use two instances of prime95 to test the temperature under load, yet one of the stickies I read said you only needed to use one..

Whats the correct thing to do?

i'm new to the problem so i'm not exactly sure what i'm doing with it, I might have misinterepreted the sticky I read

With a quad core, you need 4 instances.

Just a minute, let my crank up the other box ...

Ok. It looks like with a dual core, you need two instances - at least, the way my system is configured.

CPU cores are going to be numbered "0" and "1" for a dual core system and "0" , "1", "2", and "3" for a quad core system.

Okay so two threads then,

Also, what kind of torture test is recommended for testing CPU temperatures, blend, Small FFTs, or in place large FFTs?

 

[RiposoEterno]

tried using blend and my CPU cores didnt go anywhere near 100% but at small ffts and large ffts they hit 100% immediately

which one of those do I use?

 

[RiposoEterno]

Weird, just tried using blend again and my cores shot to 100%

Use small ffts. It produce the most heat.

use small ffts to test cpu stability, blend for cpu and ram stability, and large ffts in my opinion are useless.
