I have some troubles booting with my ram on either XMP, manual timings/speed and more loosen timings.
G.skill DDR4 4266mhz CL19 Trident Z
Z390 Phantom Gaming 6
the ram is in the QVL for my mobo.
I ran memtest86 for 30 hours without any errors and memtest64 in windows for 20 hours no errors.
The problem is not with stability (i think) I just have some hard time to boot into windows with anything above 3200mhz.
It boots like 1/10 times and is stable which i proved above
Any suggestion how to tacle the boot issue?
