ASUS MAXIMUS IX APEX - Unstable memory frequency

Mihai
Level 7
I have very unstable memory frequency.
Spec:
PSU - HX1000i
Motherboard - ASUS MAXIMUS IX APEX
Memory - HX432C18FB2/8 3200 Mhz 1.2v 18, 21, 21, 39 - 2 of them
CPU - 7700k

What I tried.
-lower memory frequncy, increase memory voltage, change SA and IO
The good thing was I change SA and IO and are more good with 1.10 SA and 1.10 IO ,work also this values 1.15 SA - 1.10 IO, with this settings I manage to lower the oscillation frequency but it is still very fast oscillation.

Any idea? Please help me!

The value changing there in CPU-Z is normal. A result of the "bus" speed changing....which I think doesn't actually exist....it's just a clock driven value that will oscillate slightly

So don't increase voltage based on that! Only base your voltage on stress test/daily computing stability...

So, run your RAM at rated speed at lowest voltage...ignore that slight change in value

For example on my system within a few seconds
79281
79282
79283
79284

I manage to fix it by enable single-rail on my PSU with Crossahir LINK!
