CPU Stress programs not working.

I'm trying to stability test my CPU using stress tests but they're not working.

With prime95 (latest version) the CPU load just hovers around 30% on the torture test and if I run Orthos (again latest version) it only stresses two CPU's ( but to 100%)

What am I doing wrong?

Thanks but when I open two instances of Orthos it just tries to stress the same cores, it's like it can't see the other two.

Opening up multiple primes doesn't help. It's not even stressing two cores fully.

download prime 95 v25.4 - this allows the user to set the number of simultaneous tests to execute. set this to the number of cores you have and execute. Dunno about orthos.

Thanks. I did that and now it it says all cores are being stressed. All say 100% in task manager but cores 2 & 3 are running 10C cooler than 1 & 2 according to Core Temp. :confused:

Before overclocking load temps look like this:

Is it worth fiddling with the heatsink or are they ok?

It's a Thermalright Ultra-120 Extreme cooler. How should I remove the thermal paste from the CPU and heatsink?

How tight should the heatsink screws be onto the mobo? I felt I could have tightened them a bit more but I didn't want to risk going too far.
