No, XMP2 is the full timings from the ram SPD.
XMP1 is most timings from the ram SPD and some timings set by the motherboard. It's usually easier to run than XMP2.
Sadly I have the same issue , they are not interested
I’ll never buy an Asus product agian now - I’m done with them
Any more info? Looks from your sig you own a Corsair kit, if it's the same problem can you clarify what memory kit? There aren't any Corsair kits on the Z690 Extreme's QVL for 6600MT. There's only so much a vendor can do and there are many [valid] reasons why assurances can't be offered with overclocking.
i’ve tried tridentZ
corsair and a third set
none of it is stable at XMP on any bios revision
