Compatible Supermicro H13SSW Memory

This 16GB DDR5 RDIMM is built for the Supermicro H13SSW motherboard. It delivers registered ECC operation at 6400 MT/s with a CL52 latency and 1.10V voltage. The module uses a 1Rx8 organisation and 288-pin form factor for exact fitment.

Suited For Registered ECC Servers

It suits administrators who need a single 16GB registered ECC DIMM that matches the board's validated population rules. Builders requiring unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or larger capacity kits should look at something else.

Speed And Latency Decide Fit

The DDR5 6400 (PC5-51200) rating with CL52 timing is the specification that determines whether this module runs at its rated speed on your platform. Verify your system documentation supports this exact speed and latency combination before purchase.

Questions about this item

Should I choose the 16GB DDR5-6400 CL52 1Rx8 RDIMM or a different capacity for my Supermicro H13SSW?

The module is a single 16GB DDR5-6400 CL52 1Rx8 registered ECC DIMM; add identical modules to reach the total capacity your motherboard manual allows per channel.

Will the DDR5-6400 rating actually run at 6400 MT/s on the H13SSW?

The board's memory controller negotiates speed at boot; with this exact-rank 1.1V CL52 RDIMM it will operate at the rated 6400 MT/s if the CPU and BIOS support that data rate.

What does the 288-pin RDIMM form factor limit in practice?

The 288-pin registered ECC RDIMM fits only DDR5 RDIMM slots — not UDIMM or SODIMM sockets — and the registered buffer lets you populate every supported slot at full speed.
