Exact-Match Server Upgrade

This 16GB DDR5 RDIMM delivers 6400MHz speed with CL52 latency at 1.1V. It is built for Supermicro H13SRA-F and H13SRA-TF motherboards that require registered ECC memory. The 1Rx8 rank configuration matches the memory controller expectations for full-capacity recognition.

Registered DDR5 Constraints

Registered architecture buffers address and command signals so the memory controller can drive every populated slot at rated speed. ECC corrects single-bit errors in flight to prevent silent data corruption. This module fits only 288-pin DDR5 RDIMM slots and will not work in UDIMM or SODIMM sockets.

1Rx8 Rank Determines Fit

The single-rank 1Rx8 organization is the specification that decides compatibility with your board's population rules. Systems requiring dual-rank or quad-rank DIMMs will not support this module at full capacity. Verify the motherboard manual for approved rank configurations before purchase.

Questions about this item

Should I choose the 16GB DDR5-6400 module or a different capacity for my Supermicro H13SRA-F?

This exact-match upgrade is a 16GB 1Rx8 Registered ECC RDIMM at 1.1V CL52, the precise rank, voltage and timing the H13SRA-F memory controller expects so it is recognised at full capacity and runs at its rated speed.

What does the 6400MHz rating deliver once the module is installed in a server?

DDR5-6400 (PC5-51200) provides a 6400 MT/s data rate with CL52 latency at 1.1V, letting the registered architecture offload the memory controller so every populated slot runs at full capacity with ECC correcting single-bit errors on the fly.

How does the 288-pin RDIMM interface limit real-world use?

The 288-pin Registered RDIMM form factor is required by the H13SRA-F / H13SRA-TF boards; it is not a UDIMM or SODIMM, and the registered design allows full-slot population at the rated 6400 MT/s while ECC prevents silent data corruption.
