Thank you so much for providing that information!! Very useful.

I was wondering if you could post a screenshot of your Computer>Sensor screen in Everest. I want to compare my voltages being reported to what you have.

One thing that's really weird is my WRITE to READ Delay (S) is set to 11T in my BIOS but Everest is reporting it as 3T.


I was also wondering how you set your tREF in the BIOS. I can't find the setting anywhere.

Here's what I have running currently, trying to match your settings best I can:

I'm able to get Prime95 to run for 4 minutes until Core 4 fails.

If you have any suggestions as to what will help, I'm open to anything. I'm still unsure as to how to set the tREF.

Thanks again for sharing your settings with us!! It has been very useful.
