Hi guys,
As the title says, I have an x399 taichi that is 'suddently' seeing only 64GB or ram out of 96GB (6 sticks of 16 GB) after a reboot.
It was seeing the full 96GB just a few days ago : no update to the bios was made, no change whatsoever.

Searched through the forum, but no luck so far.
Switched the stick,re-seated the CPU, etc.

Actual Ram slot config :
D2 : Has RAM
D1 : Has RAM
C2 : Has RAM
C1: Empty

A1 : Empty
A2 : Has RAM
B1 : Has RAM
B2 : Has Ram




Now, the BIOS seems 'blind' to 2 particular SLOT :
D1 and D2, where says nothing is inserted in those.

Ram model :
Corsair Vengeance RGB Pro 2x16 GB

Default BIOS setting seems to run without XPI @ 2133 MHz.
(Everything is on AUTO mode)


BIOS Version : P3.90
AMD Ryzen TR 1920X

Any idea would be greatly appreciated :)
Thanks guys !
