ECC RDIMM for Supermicro EPYC boards

This NEMIX RAM module is a 16GB DDR4 3200 ECC registered DIMM built for Supermicro H11SSL-C motherboards and AMD EPYC platforms. It operates at 1.2V with CL22 latency and uses a 1Rx4 organisation based on major OEM DRAM chips. The 288-pin RDIMM form factor fits server and workstation memory slots that require registered, error-correcting memory.

Suited for registered-memory servers.

This module suits administrators upgrading or repairing Supermicro H11SSL-C systems that demand DDR4 ECC RDIMM memory. It will not work in desktop or laptop boards that accept only unbuffered non-ECC DIMMs, nor in systems limited to lower speeds or different pin counts. Buyers needing unbuffered memory or higher capacities per slot should look elsewhere.

1Rx4 organisation decides platform compatibility

The single-rank 1Rx4 layout determines whether this DIMM meets the motherboard’s population rules and maximum rank-per-channel limits. Supermicro H11SSL-C memory configuration guides specify which rank structures are supported per channel, so verifying 1Rx4 compatibility before purchase avoids boot failures or reduced performance.

Questions about this item

How do I verify the module is running at 3200 MT/s with CL22 timings after installation?

Check the BIOS memory information or use a tool like CPU-Z; it should report DDR4-3200 (PC4-25600) at 1.20 V with CAS latency 22 and ECC active.

What does the package contain and is anything else required to add this memory to a Supermicro H11SSL-C?

The box includes one 16 GB 288-pin DDR4 ECC RDIMM (1Rx4); no extra parts are needed — just an available DIMM slot on the motherboard.

When should I choose this 16 GB 1Rx4 CL22 module instead of a different capacity or rank?

Select this 16 GB 1Rx4 stick when you need a single registered ECC DIMM at 3200 MT/s for the H11SSL-C; other capacities or ranks change total memory and rank-per-channel limits.
