Hello Gav mate this tutorial I am assuming it will be ok for users of 7??

Correct. :)

Thanks Shawn I thought perhaps it may have been configured for 10 with the link. :)

I just found out you can get Prime95 portable using Chocolaty(PowerShell): Chocolatey Gallery | Prime95 (Portable) 28.7

To install Prime95 (Portable), run the following command from the command line or from PowerShell:
C:\> choco install prime95.portable -version 28.7

To upgrade Prime95 (Portable), run the following command from the command line or from PowerShell:
C:\> choco upgrade prime95.portable -version 28.7

I'm trying Prime95(V. 28.10 build 19) for the first time today, to check my 4.9GHz OC.
But it only stays between 4.0 and 4.4GHz

I tried it with my OC testing settings( Vcore set to override, and CPU Ratio set to fixed), and my Daily settings(Vcore set to Adaptive, and CPU Ratio set to Dynamic) and it seems to make no difference.

I haven't seen this in any other stress test or benchmark software.

Any clues as to why?

I'm able to use my system still, with no freezing while it's running in the background, and my temps(even though my Vcore is set to 1.45) stay around a stable 68°C while stress testing, and that's while doing the small FFT, while doing Blend, it's a stable 62°C.(I just use fans to cool)

I thought, after reading some tutorial, different forums posts, and such, from the net, that I could fry bacon on my PC running this test.



running small FFT

Cliff the utility on the left side of that screenshot shows the multiplier at 41.

That's what I mean, it doesn't use my full OC(49X)
When I turn Prime95 off, or use another stress program at the same time, like CPU-Z it jumps to the correct 4.9:

(CPU-Z & Prime95 small FFT running together while AIDA64, Skype Preview and Edge with 3 tabs open(and very well at that:))

Here is a video showing what I mean:

Cliff, is CIE disabled? That will cause it to drop too.
