  • 288-pin RDIMM form factor matches the Supermicro H13SRA-F/TF slot and population rules exactly

Exact-match 64 GB DDR5 RDIMM for Supermicro

This registered ECC module delivers 64 GB at DDR5 6400 with CL52 timing and 1.1 V operation. It is built for servers that require the precise rank, voltage and timing the memory controller expects so the full capacity is recognised and runs at rated speed.

Upgrade from lower-capacity or slower DDR5 RDIMMs

The jump is worth it when your workload needs more memory bandwidth and error correction across every populated slot. Registered architecture offloads the memory controller so all slots run fully populated at full capacity while ECC corrects single-bit errors on the fly.

Practical limits of DDR5 RDIMM on this platform

Motherboard population rules dictate supported capacities and approved DIMM order. Consult the system or motherboard manual for those details before installation to ensure compatibility and correct configuration.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Supermicro H13SRA-F motherboard slots?

Yes, the module uses the exact 288-pin Registered DIMM form factor required by the H13SRA-F and H13SRA-TF boards, so it seats directly in the server's DDR5 memory slots.

What is the correct installation order when populating all channels with these 2Rx4 modules?

Follow the motherboard manual's DIMM population sequence for 2Rx4 Registered ECC memory; the common mistake is skipping the prescribed slot order, which prevents the system from recognizing the full 64GB capacity at 6400MHz.

Does the lack of a heat spreader affect long-term reliability in a fully loaded server?

The modules are built with major OEM chips rated for 1.1V operation; registered ECC architecture handles thermal load per JEDEC DDR5 specs, so no additional cooling or spreader replacement is needed over the service life.
