256 GB DDR5-4800 ECC RDIMM kit for Supermicro

This kit delivers 256 GB (4 x 64 GB) of DDR5-4800 (PC5-38400) registered ECC memory. It matches the exact rank, voltage, and timing the motherboard's memory controller expects so every slot is recognized at full capacity and runs at its rated speed. It is built for servers and workstations that require registered DIMMs with error correction.

Straightforward 288-pin RDIMM installation

Each module is a standard 288-pin registered DIMM that seats in the board's DDR5 slots. The motherboard manual defines the approved DIMM population order; following that sequence avoids a no-post condition when all four slots are filled. No heat spreader is fitted, so clearance around the CPU cooler is not affected.

Verify supported capacity

Consult the Supermicro H13SVW-NT-OS2 manual for the maximum supported capacity per channel and the required installation sequence. The board requires registered ECC RDIMMs at 1.1 V; UDIMM or SODIMM modules will not work. Confirm your system's memory-population rules match this 4 x 64 GB configuration.

Questions about this item

How can I confirm the kit is running at DDR5-4800 with CL40 after installation?

Enter the BIOS and verify the memory speed shows 4800 MT/s and CAS latency reads 40; the registered ECC design also allows the OS to report corrected-error counts as further proof of operation.

What is included in the package and what must I source separately?

The box contains the 256 GB kit as four 64 GB DDR5 288-pin RDIMM modules; no heat spreaders, cables, or tools are supplied, so have a compatible Supermicro H13SVW-NT-OS2 motherboard and anti-static wrist strap ready.

Which capacity version should I choose for a fully populated four-slot server?

Select this 256 GB (4 × 64 GB) 2Rx4 Registered ECC kit when your board's population rules call for four dual-rank modules at 1.1 V to reach maximum supported capacity.
