Dear CoffeeMachine,

Greetings, this is ASRock TSD.


We would like to provide following suggestions for verifying:

1. Please refer to the user manual to clear CMOS. (Page 28)

2. Please install the RAM on A2/B2/C2/D2 slot for verifying. (Page 7)
http://asrock.pc.cdn.bitgravity.com/Manual/X399%20Taichi.pdf
 
3. Please install the memory one by one on A2, B2, C2, D2 slot and check if each slot work, detect 16GB for each.
 
4. Please update to latest BIOS P3.30 for verifying.

My OS Windows 10 can't see all 64Gb (16X4) installed on the system. 
Only 48Gb show.
But in BIOS show 64Gb.
Please help, thanks.
