One more strange thing with memory on z690 a-Gaming d4

Hello. Noticed one more strange thing happening with memory - if i load bios optimised settings then restart then enter bios load xmp2 Profile save settings and restart my memory is 100% stable it passes several hours of any tests - aida, memtest, occt. Then after i turn off my computer and turn it on memory becomes completely unstable. If i reset to optimised defaults with restart and then load xmp2 Profile memory becomes stable again until i shut off computer completely (restart doesnt effect memory stability). My memory is G.Skill F4-3200C14Q-32GTZR is in compatibility list. Any ideas? Also where can i find VCCIO settings in bios on this motherboard? (ok i found out that there is no vccio for alder lake)

Ok, found what helped to stabilise xmp Profile for me - this one usually done only during memory oc, but looks like it helps with xmp Profile stabilisation - i disabled fast boot and enabled mch full check, so memory trains always after turning pc on. Now xmp2 is completely stable 24/7 even after completely turning pc off.
