  • @Daveyups The EC-P4BF requires that the motherboard support PCIe bifurcation. For four-drive access this means setting the slot to x4/x4/x4/x4 in the UEFI/BIOS. If there is a discrete GPU present or the board only supports x8 + x4/x4, only two drives will be accessible. In a normal slot with no bifurcation set, or if with a discrete GPU the board splits x8/x8, it will only pass through a single SSD. If your motherboard does not support PCIe bifurcation but you want to add four drives, please purchase our EC-P3X4 instead.
