Exact-match DDR5-6400 RDIMM

This 64 GB DDR5-6400 registered ECC module is built to the precise rank, voltage and timing the Supermicro H14DSH motherboard expects. It targets administrators who need a single-slot capacity upgrade that runs at rated speed without manual tuning.

Verify DIMM population rules

Check your motherboard manual for supported capacities per slot, approved population order and any BIOS revision requirements before ordering. The board uses 288-pin RDIMM slots and will not accept UDIMM or SODIMM form factors.

Lifetime replacement and US support

The bundle includes a lifetime replacement warranty and access to free US-based technical support, giving a direct escalation path if a module fails validation or develops errors in production.

Questions about this item

Does the 64GB DDR5 6400 RDIMM kit ship as a single 288-pin module or do I need to buy additional sticks?

The package contains one 64GB 288-pin DDR5 RDIMM; no extra modules are included.

Should I pick the 2Rx4 CL52 1.1V version or a different rank and latency for my Supermicro H14DSH?

The 2Rx4 CL52 1.1V specification matches the board's qualified memory list for full-capacity operation.

Will the CL52 timing on this 6400 MT/s RDIMM actually run at 6400 in my H14DSH or drop to a lower speed?

When installed per the motherboard manual, the module operates at its rated 6400 MT/s with CL52 latency.
