I have so far only noticed this after a restart, and a shut down and then boot tends to fix it. It specifically seems to appear after hitting the restart button in windows but that doesn't necessarily mean it can't happen otherwise.
I have 2 16GB modules installed, both are always detected by bios and by CPUZ but task manager only detects one of them. I have so far tried, in no particular order: bios update/flash, new windows install, reseating both ram modules. This computer is brand new.
Some basic specs for reference:
I5-13600KF
Gigabyte z790 UD AX
Corsair Vengeance 16GB DDR5 6000 x2
ARC A770
Seasonic 750w
Crucial p3 plus
Any help would be greatly appreciated. I have found no other posts of info about this issue anywhere else.
