Exact-match DDR5 RDIMM for Supermicro H13SST-GC

This 32GB DDR5 6400MHz module uses the 288-pin Registered ECC form factor your server's memory controller expects. The 2Rx8 rank structure and 1.10V operating voltage match the board's native specification so the full capacity is recognised at rated speed.

Upgrade from slower or unbuffered memory

Systems running at lower DDR5 speeds or using unregistered DIMMs cannot populate every slot at full capacity. The registered architecture offloads the memory controller while ECC corrects single-bit errors on the fly, making the jump worthwhile when stability and maximum population matter.

Sustained-load behaviour with registered ECC

Under continuous workloads the buffered design keeps every populated slot running at 6400MHz without controller overload. ECC protection operates cycle by cycle, preventing silent data corruption and unplanned reboots during extended production runs.

Questions about this item

Will the 288-pin RDIMM fit the Supermicro H13SST-GC motherboard slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots required by the Supermicro H13SST-GC motherboard.

What is the correct order to populate the DIMM slots during installation?

Follow the motherboard manual for the approved DIMM population order; server boards often require specific slots to be filled first for proper memory controller initialization.

Does the module require any firmware updates or ongoing maintenance after installation?

No firmware updates are needed for the memory itself; ensure the system BIOS is current for best compatibility, and the ECC function will correct single-bit errors automatically during operation.
