Target server and capacity

This is a 32 GB DDR5 registered ECC RDIMM built for the Supermicro H13SST-G motherboard. It delivers 6400 MT/s speed at CL52 latency and 1.1 V operation using a 2Rx8 organisation. The module suits administrators expanding memory in compatible Supermicro platforms that require registered DIMMs with error correction.

Upgrade path and fit

It replaces lower-capacity or slower DDR5 RDIMMs in the same server when the board's memory-population rules allow the 2Rx8 rank configuration. The jump is worthwhile when workloads need the full 32 GB per slot at the rated 6400 MT/s data rate and the platform validates this exact part number.

Pre-order checks

Confirm the motherboard manual lists MR51200-328K1 as a supported module and verify the required DIMM population order for your CPU configuration. Ensure the system accepts 288-pin registered ECC DDR5 at 1.1 V and that no BIOS limitation restricts the 32 GB capacity per slot.

Questions about this item

Will the 288-pin RDIMM fit the Supermicro H13SST-G motherboard DIMM slots?

Yes, the module is a 288-pin DDR5 RDIMM built to the exact form factor the H13SST-G requires, so it seats correctly in the server's memory slots.

What installation step is most often missed when adding this 2Rx8 registered ECC module?

The board's manual specifies a strict population order for registered DIMMs; skipping that sequence is the common error that prevents the system from recognising the full 32 GB at 6400 MT/s.

When should the 1.1 V DDR5 RDIMM be replaced in a production server?

Replace the module if ECC logs show rising correctable-error counts, if the server fails POST with the DIMM installed, or during a planned hardware-refresh cycle to maintain registered-ECC reliability.
