NEMIX RAM DDR5 4800 ECC Registered RDIMM 192GB (6x32GB) CL40 1.1V 288-Pin memory upgrade for Supermicro H13SSH

Exact-fit DDR5-4800 RDIMM kit

This 192GB kit contains six 32GB DDR5-4800 Registered ECC modules built to the Supermicro H13SSH memory specification. The 2Rx8 organization, 1.10V operating voltage and CL40 timing match the controller requirements so the system recognizes full capacity at rated speed. It is intended for administrators who need maximum supported memory in that specific platform.

Upgrading from partial or slower populations

Replacing a smaller or mixed-capacity installation with this matched six-module kit eliminates population-rule conflicts and lets every channel run at DDR5-4800. The jump is worth it when the workload requires the full 192GB address space and the board's qualified-vendor list calls for 2Rx8 Registered DIMMs at 1.10V. Builders using UDIMMs, SODIMMs or different rank configurations cannot use this kit.

Registered DDR5 interface constraints

The Registered architecture buffers address and command signals so the memory controller can drive all slots at the rated data rate, while on-die ECC corrects single-bit errors before they reach the CPU. DDR5-4800 (PC5-38400) sets the maximum transfer rate; the platform cannot exceed this speed regardless of module headroom. Systems that require unbuffered DIMMs, a different pin count, or a lower voltage standard are incompatible.
