System-Specific DDR4 ECC RDIMM

This NEMIX RAM module is a 64GB DDR4 3200 registered DIMM built for the Supermicro H11SSL-C motherboard and AMD EPYC platforms. It delivers ECC protection and registered signalling for stable operation in server and workstation environments. The single-module design simplifies capacity scaling in qualified systems.

Registered 2Rx4 organisation at CL22

The module uses a 2Rx4 rank configuration with CAS latency 22 and operates at 1.20V across 288 pins. Registered buffering reduces electrical load on the memory controller, allowing larger populations per channel. ECC circuitry corrects single-bit errors to maintain data integrity under sustained workloads.

64GB per slot for dense memory configurations

One module provides 64GB, letting a populated board reach high totals without consuming extra slots. The DDR4 3200 speed matches the platform's rated transfer rate of PC4-25600. Systems requiring more capacity must add additional qualified RDIMMs; non-ECC or unbuffered modules will not function in this registered architecture.

Questions about this item

What does the 3200 speed rating mean once this module is installed in a Supermicro H11SSL-C?

The module runs at 3200 MT/s with CL22 latency, delivering DDR4-3200 performance in compatible EPYC platforms.

How does the PC4-25600 designation affect usable throughput on this registered DIMM?

PC4-25600 identifies the DDR4-3200 data rate; actual throughput depends on the motherboard memory controller and channel configuration.

What physical slot and clearance does the 288-pin RDIMM need on the H11SSL-C?

It fits a standard 288-pin DDR4 RDIMM slot; the module has no heat spreader, so it clears most CPU coolers and dense layouts.
