Server memory upgrade

This 64GB DDR5 registered DIMM is built for the Supermicro H13SST-G motherboard and targets administrators who need to expand capacity in production servers. It delivers ECC protection and registered buffering so fully populated slots remain stable under continuous workloads.

CL52 6400MHz timing

The module runs at DDR5 6400 (PC5-51200) with a CAS latency of CL52 at 1.1V, matching the exact speed, voltage and timing the board's memory controller expects for native recognition and rated performance.

288-pin RDIMM fit

The 288-pin registered form factor fits only motherboards that require RDIMMs — not UDIMMs or SODIMMs — and follows the H13SST-G population rules detailed in the system manual. ECC corrects single-bit errors on the fly while the registered architecture offloads the memory controller, freeing the platform to run every slot at full capacity.

Questions about this item

What does the 6400 speed rating mean once this module is installed in a Supermicro H13SST-G system?

The module runs at DDR5 6400 (PC5-51200) data rate. The registered buffer lets every populated slot operate at that rated speed without down-clocking.

How does the 288-pin RDIMM interface and registered design affect what the memory controller can do?

The 288-pin RDIMM form factor is required by the board; the registered architecture buffers address and command signals so the controller can drive a fully populated configuration at full capacity.

What physical slot and clearance does this 64GB stick need to fit the H13SST-G?

It installs in a standard 288-pin DDR5 RDIMM slot. No heat spreader is fitted, so it clears standard server DIMM spacing and CPU cooler overhang.
