● a: PCIe 5.0 refers to the PCIe of the fifth generation, and x16 refers to the
physical slot width.
● b: The x16 in brackets indicates that the link bandwidth is x16.
● c: The default link bandwidth of FlexIO card 1 is x8. The link bandwidth can be
extended to x16 using cables.
● d: FlexIO card 1 supports the Socket Direct function when it is connected to the
two CPUs through high-speed cables.
● e: The default link bandwidth of FlexIO card 2 is x8. The link bandwidth can be
extended to x16 using cables. When FlexIO card 1 supports the Socket-Direct
function, FlexIO card 2 can only support x8.
● The PCIe x16 slots are compatible with PCIe x16, PCIe x8, PCIe x4, and PCIe
x1 cards. The bandwidth of the PCIe slot cannot be less than that of the
inserted PCIe card.
● The FHHL PCIe slots are compatible with FHHL PCIe cards and HHHL PCIe
cards.
● The maximum power supply of each PCIe slot is 75 W.
