512 GB DDR5 6400 ECC RDIMM Kit

This 512 GB kit contains four 128 GB DDR5 6400 CL52 registered ECC modules built for Supermicro X14SBW-F systems. It targets server and workstation administrators who need maximum registered capacity with error correction. The modules run at 1.1 V and use a 288-pin RDIMM form factor with 4Rx4 organisation.

Tool-free DIMM installation with seating checks

Each module presses vertically into the 288-pin DDR5 slots until the side latches click. The registered buffer adds electrical load, so the board must support 4Rx4 population rules; mis-seated modules or incorrect slot order are the most common causes of POST failure. No heat spreader is fitted, so airflow across the PCB is required.

Verify Supermicro X14SBW-F memory population guide

Confirm the motherboard BIOS revision supports 512 GB total capacity and 4Rx4 registered DIMMs at 6400 MT/s. Check that the CPU memory controller accepts 1.1 V DDR5 and that the chassis provides adequate airflow over bare modules. Ensure all four slots are populated identically for the kit to operate as specified.

Questions about this item

How do I verify the 6400 CL52 kit is running at its rated speed after installation?

Enter the server BIOS and confirm the memory frequency shows 6400 MT/s with CAS latency 52 at 1.10 V.

What exactly ships in the box and do I need any extra parts?

The box contains four 128 GB DDR5 288-pin ECC RDIMM modules; no additional components are required for installation.

This kit is listed as a single 512 GB 4 x 128 GB version — is there any other capacity or rank option to consider?

Only the 512 GB 4Rx4 kit with part number MR51200-744K4 is offered for this Supermicro platform.
