I have the following system for some years running just fine.

ASRock Z77 Extreme4
Intel Core i7-3770 @ 3.40 GHz
2 x Corsair Dominator Platinum 4 GB 2.133MHz C9

Lately I am having memory related issues. The memory is running using the XMP settings.
I tried one module per time, using different slots.
The error decreased using one module, but still occurs.

Since the memory XMP speed is OC, my idea was to use a lower speed. But whatever speed I choose in UEFI, it still running the XMP settings.
Even when I change the XMP setting to Auto the UEFI still uses the XMP.

How to change de memory speed?
Or any other ideas how to fix the memory issues?
