NEMIX RAM DDR5 4800 ECC RDIMM 96GB 2x48GB CL40 1.1V Supermicro H13SSW memory upgrade

Exact-match upgrade for Supermicro H13SSW

This 96 GB kit provides two 48 GB DDR5 4800 RDIMMs built to the Supermicro H13SSW memory controller specifications. Registered ECC architecture with 2Rx8 organisation ensures full-capacity recognition and single-bit error correction in production workloads. The modules operate at 1.1 V with CL40 timing exactly as the platform expects.

Installation notes and common issues

The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM sockets will not accept these modules. Server boards often require a specific population sequence across channels, so consult the H13SSW manual for the approved slot order before seating the pair. Mismatched rank or voltage settings in the BIOS can prevent the kit from training at its rated speed.

DDR5 RDIMM practical limits

Registered DDR5 modules add a buffer that stabilises heavy loads but introduces one extra cycle of latency compared with unbuffered memory. The DDR5 4800 JEDEC ceiling caps bandwidth at PC5-38400 per module, so applications needing higher throughput must rely on population density rather than frequency headroom. ECC parity bits reduce usable capacity slightly versus non-ECC equivalents of the same nominal size.
