Additional InformationAcross the front of the MiTAC B8261T85E8HR-2T-N-HE are 8x 2.5-inch hot-swappable U.2 NVMe drive bays. Dual AMD SP5 sockets support AMD EPYC 9005 and 9004 Series processors with a maximum TDP of 500W. Memory is distributed across 24x DDR5 DIMM slots, with 12x slots allocated to each processor, supporting up to 6TB of memory at speeds of up to 6400MT/s. GPU and PCIe expansion is divided among 6x PCIe Gen5 x16 slots. Four full-height, 10.5-inch, double-width slots accommodate up to 4x GPU accelerators, while an additional 2x half-height, half-length PCIe Gen5 x16 slots provide connectivity for other expansion devices.
