Question Attempting to make XMP stable

[poodude28]

Hello, I've been struggling to make my XMP stable, I've tried reducing the speed, loosening the timings, increasing DRAM voltage, and I still get no signal (but get to the desktop after a few seconds) at 3200MHz.

The only thing I haven't tried changing is VCCSA because I feel uncomfortable about it, the bios says my VCCSA is 0.875 when it's being monitored, could turning this up help? That's sort of low isn't it?


I have the Gigabyte Z690 UD AX DDR4 Motherboard, an i5 13600k, and 2x16GB 3200MHz rated Corsair RAM in slots 2 and 4.


I can get to the desktop with 2600MHz with the timings 18/22/22/42, 2800 causes no signal.

Would changing my internal VCCSA to 1.3 help and be safe?

Was this a kit of two sticks in one package or 2 separate sticks in different packages?

Two sticks one package

First thing I would try is to set XMP in bios.
Then manually set VDimm voltage to 1.35-1.375v.
Then save and exit.
Some boards do not set voltage correctly when enabling XMP.
