[SOLVED] Corsair RAM (CMW16GX4M2A2666C16) not able to run at 2666mhz ?

ASUS PRIME Z490-P
i5 10600K
CMW16GX4M2A2666C16 (from the same box)

The motherboard is compatible with up to 4600mhz ram and i5 compatible up to 2666mhz ram. I can only use 2133mhz on my XMP profile in BIOS and it's only showing 1066mhz when I check CPU-Z.

Bios version ?

CPU-Z is correct 2 x 1066 = 2132mhz

XMP is for easy Overclocking however some profiles do not work with OC RAM.
You should manually enter SPD timings and voltage in Bios.

Change it back to 2666 then increase the voltage to 1.25 if that fails then 1.3
