Exact DDR5-4800 RDIMM kit for Supermicro

This 128GB kit delivers four 32GB DDR5 modules rated at 4800 MT/s with CL40 timing and 1.1V operation. It is built for servers that require registered ECC memory and will only work in systems accepting 288-pin RDIMMs.

Registered ECC design with 2Rx8 organisation

The registered architecture buffers address and command signals so the memory controller stays stable when all slots are populated. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Four matched modules in a single kit

The package contains four 32GB RDIMMs pre-tested as a matched set, eliminating the guesswork of mixing individual sticks. Major OEM DRAM from Samsung, Micron or Hynix underpins the lifetime replacement warranty and US-based technical support.

Questions about this item

What speed does the DDR5 4800 (PC5-38400) interface run at in this kit?

The modules operate at DDR5 4800 with a CAS latency of CL40, delivering the rated PC5-38400 data rate when the motherboard runs them at spec.

What physical slot and form factor do these 288-pin RDIMMs require?

They need a 288-pin DDR5 RDIMM slot; the registered form factor is keyed differently from UDIMM or SODIMM and will not fit those sockets.

How should the four 32 GB modules be installed on the Supermicro H13SVW-NT-OS1, and what step is often missed?

Follow the motherboard manual for the approved population order; a common mistake is filling slots sequentially instead of the prescribed channel sequence for four DIMMs.
