Exact-Match DDR5 Server Upgrade

This 64GB kit contains four 16GB DDR5-6400 RDIMMs rated at CL52 and 1.1V. The modules are registered ECC with 1Rx8 organisation and use the 288-pin form factor required by the Supermicro H13SSL-NT motherboard.

For Populated Enterprise Boards

It suits administrators who must fill every slot on a compatible Supermicro platform with registered memory that the controller recognises at full speed. Builders needing unbuffered UDIMMs, SODIMMs, or non-ECC modules should look elsewhere.

Sustained Registered ECC Stability

Registered buffering offloads the memory controller so all four modules run continuously at rated frequency without signal degradation. On-die ECC corrects single-bit errors during extended workloads, preventing silent data corruption that would otherwise trigger unplanned reboots.

Questions about this item

What motherboard must I already have for this 64GB DDR5-6400 RDIMM kit to be recognised at full capacity and speed?

The kit is validated for the Supermicro H13SSL-NT motherboard, which accepts 288-pin registered DDR5 modules.

How will these 1Rx8 registered ECC modules behave if I populate the remaining DIMM slots on the same board?

Registered architecture offloads the memory controller so every slot can run fully populated at the rated 6400 MT/s with ECC active.

How can I confirm the kit is running at its specified 6400 MT/s CL52 1.10 V after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should report DDR5-6400, CL52, 1.10 V and ECC registered for each of the four 16 GB modules.
