NEMIX RAM 64GB DDR5 6400 CL52 2Rx4 ECC RDIMM H13SSL-NT memory upgrade

Exact-match DDR5-6400 RDIMM for Supermicro H13SSL-NT

This 64 GB DDR5-6400 module delivers PC5-51200 bandwidth at 1.1 V with CL52 latency. It is a 288-pin registered ECC DIMM built to the precise rank and timing the motherboard's memory controller expects, so the server recognises the full capacity and runs at rated speed.

Registered ECC architecture and 288-pin form factor

The registered design buffers address and command signals, allowing every slot to be populated at full capacity while offloading the memory controller. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The 288-pin RDIMM keying matches the board's slots exactly — no UDIMM or SODIMM will fit.

Replaces slower or lower-capacity DDR5 RDIMMs

Upgrading from slower DDR5 modules or smaller DIMMs restores the bandwidth and density the platform was designed for, which is critical when all memory channels are filled. The jump is worth it when workloads demand maximum registered ECC capacity at the board's native 6400 MT/s data rate. Buyers who need unbuffered UDIMMs or non-ECC memory should look elsewhere.
