512GB DDR5-6400 ECC RDIMM kit

This NEMIX RAM kit delivers 512GB of DDR5 memory as four 128GB registered ECC RDIMMs rated at 6400 MT/s with CL52 latency and 1.10V operation. The modules use a 2Rx4 organization and 288-pin form factor built for server platforms.

Suited for Supermicro H13DSH upgrades

The kit matches the Supermicro H13DSH motherboard's requirement for registered DDR5 RDIMMs with ECC, allowing full-capacity population across supported slots. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC memory, or a different speed grade should select another product.

Check motherboard manual before ordering

Verify the H13DSH memory population rules, maximum supported capacity per slot, and approved DIMM installation order in the system or motherboard manual. Ensure the platform firmware is current enough to initialize the full 512GB configuration at the rated DDR5-6400 speed.

Questions about this item

What motherboard must I already have for this 512GB DDR5 6400 kit to be recognised at full capacity and rated speed?

The kit is verified for the Supermicro H13DSH motherboard, which expects 288-pin registered DDR5 ECC RDIMMs at 1.1V with CL52 timing.

How will these 2Rx4 registered ECC modules behave if I keep older DDR5 RDIMMs in the remaining slots?

Mixing ranks or timings can force the controller to down-clock all channels; the board manual should be consulted for approved population rules before adding these 128GB modules.

How can I confirm the 512GB kit is running at DDR5 6400 with ECC active after installation?

Check the BIOS memory information screen for 6400 MT/s speed, CL52 latency, registered mode and ECC enabled across all four 128GB modules.
