Exact-match DDR5 RDIMM for Supermicro H14SST-GE

This 64GB DDR5 6400 module is built to the precise rank, voltage and timing the Supermicro H14SST-GE memory controller expects. It installs as a 288-pin Registered ECC DIMM so the board recognises full capacity at rated speed.

Capacity and registered headroom

The 64GB 2Rx4 configuration lets the server populate every slot at full density while the registered architecture offloads the memory controller. ECC corrects single-bit errors on the fly, preventing silent data corruption during sustained workloads.

CL52 1.1V DDR5 6400 specification

Rated at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, this module will only run at its labelled speed and timing when the platform supports that exact data rate. Buyers whose systems require a different DDR5 speed or voltage must choose a matching part instead.

Questions about this item

Will this 2Rx4 DDR5 6400 RDIMM work in a Supermicro H14SST-GE that already has 1Rx8 modules installed?

The board requires registered DDR5 RDIMMs; mixing ranks is allowed only if the manual lists the specific population order, so check the motherboard guide before combining 2Rx4 and 1Rx8 sticks.

How can I confirm the memory is running at 6400 MT/s with CL52 and ECC active after installation?

Enter BIOS or use a tool like dmidecode to verify speed shows 6400 MT/s, CAS latency reads 52, and ECC status reports enabled and operational.

Does the package include only the 64 GB DDR5 6400 2Rx4 ECC RDIMM, or are heat spreaders and cables also supplied?

The kit contains the single 64 GB DDR5 6400 CL52 1.1 V 2Rx4 288-pin ECC registered RDIMM; no heat spreader, cables or extra accessories are included.
