What this kit is and who uses it

This NEMIX RAM kit provides 256GB of DDR5 memory across eight 32GB RDIMM modules rated at 5600MHz with CL46 latency. It is built for administrators upgrading a Supermicro H13SRH motherboard that requires registered ECC modules in a fully populated configuration.

Suitable builds and mismatched needs

The kit suits servers that mandate 288-pin registered ECC DDR5 at 1.1V and 2Rx8 organization. It will not work for systems that accept only unbuffered UDIMMs, SODIMM form factors, or non-ECC memory, nor for boards limited to lower maximum capacities or different voltage requirements.

The spec that decides fit

The motherboard must support 288-pin DDR5 RDIMM modules at 5600MHz (PC5-44800) with CL46 timing, 1.1V operation, and 2Rx8 registered ECC architecture; otherwise the modules will not be recognized or will run at reduced stability.

Highlights

Questions about this item

What motherboard and DDR generation must I already have for this 256GB DDR5 5600MHz CL46 ECC Registered RDIMM kit to work?

You need a Supermicro H13SRH motherboard with DDR5 memory slots; the kit is an exact-match upgrade validated for that board's 288-pin RDIMM population rules.

Can I mix these 2Rx8 1.1V CL46 registered modules with older DDR5 RDIMMs of different rank or timing in the same H13SRH system?

Mixing ranks, voltages or CAS latencies is not recommended; the H13SRH memory controller expects identical 2Rx8 1.1V CL46 modules in every populated slot for stable full-capacity operation.

How do I confirm the kit is running at 5600MHz with ECC active after installation?

Enter the BIOS or use a hardware-inventory tool such as dmidecode; verify the reported speed shows 5600 MT/s, the module type reads Registered ECC, and total capacity reads 256GB across all eight slots.
