Question X399 Taichi Quad channel ram error

[manlo121]

Bought 2 of these, and I can boot them separately as 2-Dimm, so the ram are fine.
Ballistix Sport LT 32GB Kit (16GBx2) DDR4 2400 MT/s (PC4-19200) DIMM 288-Pin

But when I add them as quad, 4-Dimm, it just won't boot...so frustrated. Same brand, speed, size, and chip typet
Is there some BIOS setting I am missing?

It might run at 2133mhz.

Anyway you should have consulted memory QVL before purchase.
Also should have gone with 4x16GB kit instead of 2 kits 2x16GB.
