Installing NVMe Drives

OCuLink cables (CBL-SAST-1021) are required to support NVMe drives.

BIOS setup menu "CPU2 SLOT1 PCI-E 3.0 x16 OPROM" only supports condition 1.
BIOS setup menu "CPU1 SLOT2 PCI-E 3.0 x16 OPROM" only supports condition 4.
NVMe and Expansion Cards
The two PCI-E slots on the motherboard also provide support for NVMe, thus limiting slots
for expansion cards in the following combinations:
One or two NVMe drives (Condition 2) leave one PCI-E x8 and one PCI-E x16 slot available.
Three or four NVMe drives (Condition 3) leave one PCI-E x16 slots available.
Five or six NVMe drives (Condition 3 + 5) leave one PCI-E x8 slot available.
Seven or eight NVMe drives (Condition 3 + 6) leave no PCI-E slots available on the MB.
