NEMIX RAM DDR5 ECC RDIMM 128GB 8x16GB 4800 CL40 1Rx8 1.1V 288-pin Supermicro H13SSH-E memory upgrade

Supermicro H13SSH-E memory kit

This 128GB kit contains eight 16GB DDR5 ECC Registered DIMMs built to the exact rank, voltage and timing the Supermicro H13SSH-E memory controller expects. Each module runs at 4800MHz with CL40 latency at 1.1V and uses the 288-pin RDIMM form factor the board requires. The registered architecture allows all slots to be fully populated while ECC corrects single-bit errors on the fly.

Replacing slower or smaller DDR5 RDIMMs

The upgrade is worth it when your current configuration cannot reach the board's maximum supported capacity or operates at a lower data rate. Moving to this eight-module kit fills every channel with 1Rx8 registered memory so the controller runs at its rated 4800MHz speed without downclocking. It is not for systems that accept only unbuffered UDIMMs or SODIMMs, or for builds that need a different voltage or pin layout.

Capacity and headroom

Eight 16GB modules deliver 128GB of registered ECC memory, giving headroom for large virtualisation hosts, database buffers and multi-tenant workloads that keep every core fed. The 1Rx8 organisation and registered design let the memory controller address the full population at rated speed, while ECC prevents silent corruption. The limit is the motherboard's own maximum supported capacity and population rules, which must be confirmed in the system manual before installation.
