NEMIX RAM 512GB 4x128GB DDR5 6400 CL52 2Rx4 ECC RDIMM Supermicro H14SSL-N

512GB DDR5 6400 ECC RDIMM kit for Supermicro

This 512GB kit contains four 128GB DDR5 6400 registered ECC RDIMMs built for the Supermicro H14SSL-N motherboard. Each module runs at 1.1V with CL52 latency and a 2Rx4 organisation. The exact-match specification ensures the memory controller recognises the full capacity at rated speed without manual tuning. It targets administrators upgrading or populating this specific server platform.

288-pin registered form factor with major OEM DRAM

The modules use the 288-pin RDIMM form factor required by the H14SSL-N, not UDIMM or SODIMM. Registered buffering reduces electrical load on the memory controller so all slots can run fully populated at full capacity. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots. DRAM comes from Samsung, Micron or Hynix depending on supply. No heat spreader is fitted.

Four-module kit simplifies population rules

The package delivers four matched 128GB DIMMs in a single kit, removing the guesswork of mixing ranks or speeds across channels. Population order still follows the motherboard manual, but identical modules eliminate timing mismatches. Lifetime replacement coverage and US-based technical support back the kit after installation. Buyers needing a different total capacity or a non-registered form factor should look elsewhere.
