G295-D21 front panelAdditional Information

There are 12x memory modules slots on the Gigabyte G295-D21 GPU Server motherboard for 1x DIMM Per Channel (1DPC). With 1DPC memory can run at top speeds of up to 8000MT/s using registered DIMMs (RDIMM) or up to 12800MT/s using Multiplexed Rank DIMMs (MRDIMM). MRDIMMs are only supported with select CPUs. Administrators have 2x options for drive support; either 4x 2.5-inch Gen5 NVMe, SATA or SAS-4 drives or up to 6x 2.5-inch SATA or SAS-4 drive types. There is also a separate SKU that supports up to 4x native NVMe drives with low profile PCIe slots.

In addition, there is an internal PCIe Gen4 x2 slot on the system board that can be used to host an NVMe M.2 drive to boot the OS. 4x full-height, full-length x16 PCIe Gen6 slots support up to 4x Gen6 double-wide GPUs. 2x more PCIe Gen6 slots, one with x16 lanes and one with x8 lanes can be used to support NICs and a storage controller, if needed. Dual 10Gb/s LAN ports provide basic networking communications along with a Management LAN port for remote management of the system. Powering the system are dual, redundant 3000W 80 PLUS Titanium power supply units (PSU).
