Exact-match DDR5 upgrade

This 32 GB DDR5 6400 MHz CL52 registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H14SST-GE motherboard expects. It installs as a 288-pin module and runs at its rated 1.1 V speed without manual tuning.

Server builders needing registered ECC

The module suits administrators populating every slot on a Supermicro H14SST-GE for maximum capacity and error correction. It is not for desktop boards that accept only unbuffered UDIMMs, nor for systems that require SODIMM form factors.

Fits 288-pin RDIMM slots

Each stick occupies one registered DIMM slot and draws 1.1 V, leaving the memory controller free to drive a full population at 6400 MHz. The registered design reduces electrical load so all channels remain stable at the rated frequency.

Questions about this item

Does my Supermicro H14SST-GE motherboard need a specific DIMM population order for this 2Rx8 registered module?

Yes, the H14SST-GE manual defines the supported capacities and approved DIMM population order; follow that sequence so the 32 GB module is recognised at full capacity and runs at DDR5-6400.

Will this 288-pin DDR5 RDIMM work in a board that only accepts unbuffered UDIMMs?

No, this is a registered (buffered) RDIMM and requires a motherboard designed for registered memory; a UDIMM-only board will not accept it.

How can I confirm the kit is running at its rated 6400 MT/s and CL52 after installation?

Enter the BIOS or use a system-information tool to verify the memory speed shows 6400 MT/s (PC5-51200) and the CAS latency reads CL52 at 1.1 V.
