Exact-match 512GB DDR5-6400 kit for Supermicro

This 512GB kit contains eight 64GB DDR5 6400 RDIMMs built to the registered ECC specification the Supermicro X14QBH+ memory controller expects. It targets server administrators who need full-capacity population at rated speed with error correction active.

Straightforward installation

Each module slots into a standard 288-pin DDR5 RDIMM socket at 1.1V; no heat spreader means clearance is not a concern. The only common issue is ignoring the motherboard's required DIMM-population sequence, which prevents the system from recognising the full 512GB.

Verify manual limits before ordering

Confirm the board's maximum supported capacity per slot and approved population order for 4Rx4 modules in the Supermicro X14QBH+ manual. Buyers who need a different total capacity or unbuffered UDIMMs should select another kit.

Questions about this item

How can I confirm the kit is running at the rated DDR5 6400 speed with CL52 latency after installation?

Enter the server BIOS or UEFI and verify the memory frequency reads 6400 MT/s and the CAS latency shows 52; the registered ECC design ensures the controller recognises all eight 64 GB modules at the specified 1.10 V.

What exactly ships in the package and are any extra components required?

The box contains the 512 GB kit as eight 64 GB 288-pin DDR5 RDIMMs; no heat spreaders, cables, or additional parts are included or needed for installation.

Which capacity or version should I choose if my Supermicro X14QBH+ manual lists multiple population rules?

Select this 512 GB 8 x 64 GB 4Rx4 registered ECC kit (part MR51200-944K8) when the manual calls for a full eight-DIMM population at DDR5 6400 with 1.10 V CL52 timing.
