4x 288-pin DDR4-2666 UDIMM, non-ECC 4 × DDR4 DIMM · up to 128 GB total · 2666 MT/s

128 GB (4x32 GB) is confirmed by HP's US data sheet and Kingston; HP's Japanese CTO sheet lists 64 GB max, likely an earlier limit. Install in pairs for dual channel. DDR4-2666 only with 9th-Gen i5/i7/i9; i3/Pentium/Celeron run memory at DDR4-2400. Non-ECC UDIMM only, and use low-profile modules so the SFF lid closes.

M.2 2230/2280 NVMe slot (PCIe 3.0 x4) SSD M.2 2230 / M.2 2280 (NVMe) · up to 1.024 TB

Key M slot wired for PCIe 3.0 x4 NVMe; M.2 SATA modules are not offered by HP and may not be supported on these business desktops, so verify before buying one. HP validated drives up to 1 TB; larger NVMe SSDs usually work. A separate Key E 2230 slot holds only the WLAN/BT card. Optional Optane caching applies to SATA drives, not NVMe.
