Opinions on Prime95

[woodson75]

Just wondered what people think of Prime95? Is this a good piece of software to run on a new build just to check all is well, or is it more aimed at overclockers?

Thanks for any advice

System stress test. Good to see if you actually have a stable system

I run memtest86+ first. It needs no os and is a good basic test.

Prime95 is easy to do, but it does not use the types of instructions that normally occur.
I like OCCT as a good stress test app.

I think it was originally developed to find prime numbers. They probably found out that it stresses the CPU quite a bit so they added a benchmark function. The program will run calculations to find prime numbers. It runs a second calculation to check itself and when it encounters an error it stops the operation on that core.

This is useful for overclocking because you can find instabilities without crashing your system (often).

I can overclock my A10-5800k to 4ghz from 3.8ghz. But once I hit 4.1ghz core #3 fails. (This is without voltage increases)

Prime95 is a good tool to have and I would certainly play around with it when you have the time.

Outdated.

I use AIDA64 and OCCT.
