Exact-match DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit delivers 256 GB across four 64 GB DDR5-4800 registered ECC modules. Each DIMM runs at 1.10 V with CL40 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor matches the Supermicro H13SSH-E motherboard requirements exactly.

Suited for servers needing maximum registered ECC

Ideal for administrators populating every slot on a Supermicro H13SSH-E board with validated DDR5 RDIMMs. Not for workstations or desktops that require unbuffered UDIMMs, nor for systems limited to lower total memory capacities or different DDR generations.

Verify motherboard population rules and slot order

Consult the Supermicro H13SSH-E manual for approved DIMM population sequences and maximum supported capacity per channel before installation. Confirm the platform accepts 2Rx4 registered modules at the full 256 GB kit level and that BIOS settings match the 4800 MT/s rated speed.

Questions about this item

What motherboard must I already have for this 256GB DDR5 4800 RDIMM kit to work?

The kit is verified for the Supermicro H13SSH-E motherboard and requires that board's 288-pin RDIMM slots and memory-population rules.

Can I mix these 64GB 2Rx4 modules with older DDR5 RDIMMs of a different rank or speed on the same board?

Mixing ranks or speeds is not recommended; the board's memory controller expects identical 2Rx4 DDR5-4800 modules in the prescribed slots for stable operation.

How do I confirm the full 256GB is recognised and running at CL40 1.1V after installation?

Enter the BIOS or use a hardware-information tool to verify all four DIMMs show 64GB each, DDR5-4800 speed, CL40 timings and 1.1V voltage.
