NEMIX RAM
Four-module 128 GB DDR5 4800 ECC registered kit built for the ASUS Z13PE-D16 server board
This 128GB DDR5 kit contains four 32GB registered ECC RDIMMs built for the ASUS Z13PE-D16 server board. It targets administrators who need maximum capacity per channel in a validated configuration. The modules operate at 4800 MT/s with CL40 latency at 1.1V. Buyers who need non-ECC or unbuffered DIMMs for a workstation should look elsewhere.
Each module uses a 1Rx4 organisation and major OEM chips from Samsung, Micron or Hynix without a heat spreader. The 288-pin RDIMM form factor fits the Z13PE-D16 memory slots and the registered buffer reduces electrical load on the memory controller. Systems that require UDIMM or LRDIMM pinouts cannot use this kit.
Running at 1.1V keeps power draw low for dense server deployments. The absence of heat spreaders relies on chassis airflow for cooling, so adequate front-to-back air movement is required. No active cooling or additional voltage headroom is needed for standard operation.

The modules run at 4800 MT/s with a PC5-38400 bandwidth rating, and the memory controller on the ASUS Z13PE-D16 will operate them at that speed when all four slots are populated.
Yes, they are 288-pin DDR5 RDIMMs without heat spreaders, matching the Z13PE-D16 DIMM slots and leaving room for CPU coolers.
Populate all four channels following the board's population guide, seat each RDIMM until the retention clips click, then enter the BIOS to confirm the 128 GB total and enable ECC.
