NEMIX RAM 64GB (4x16GB) DDR5-4800 CL40 1.1V ECC RDIMM Supermicro H14DSH

Exact-match DDR5-4800 kit for Supermicro H14DSH

This 64GB kit contains four 16GB DDR5-4800 RDIMMs rated at CL40 and 1.10V. Each module uses a 1Rx8 registered ECC design that matches the memory controller expectations of the Supermicro H14DSH motherboard. The 288-pin form factor fits the server board's DIMM slots directly.

Replaces partial or slower DDR5 populations

Installing this kit fills four slots with matched rank, voltage and timing so the server recognises the full 64GB at rated speed. The jump is worth it when the board currently runs fewer modules, mixed ranks or lower-speed DDR5 that forces the controller to downclock. Builders who need a second kit for additional channels or higher total capacity should verify the board's maximum supported memory before purchasing.

Limited by DDR5-4800 JEDEC timing

The modules operate at the standard DDR5-4800 (PC5-38400) data rate with CL40 latency; faster DDR5 speeds are not supported by this kit. Registered buffering adds one cycle of command delay, which is required for full-slot stability on this platform but prevents use in systems that accept only unbuffered UDIMMs. ECC corrects single-bit errors on the fly, yet it cannot protect against multi-bit failures or replace system-level redundancy.
