128GB DDR5 RDIMM for Supermicro X14SRA-F

This 128GB DDR5-6400 registered ECC module is built for the Supermicro X14SRA-F motherboard. It runs at 1.1V with CL52 latency and a 4Rx4 organisation across 288 pins. The registered design allows full-capacity population while ECC corrects single-bit errors on the fly.

Who this suits and who should look elsewhere

This suits administrators upgrading the named Supermicro platform with the exact rank, voltage and timing the memory controller expects. Builders using consumer boards, UDIMM slots or systems that cannot accept registered ECC DDR5 modules should look elsewhere.

The specification that decides fit

The 4Rx4 registered ECC configuration at 1.1V and CL52 is the single specification that decides whether this module will be recognised at full capacity and run at its rated speed on the target motherboard.

Questions about this item

What motherboard slot and DDR generation does the 288-pin RDIMM require?

The module fits a 288-pin DDR5 RDIMM slot on the motherboard.

Can the 4Rx4 registered ECC modules run in a system that currently uses 2Rx8 unbuffered DIMMs?

No, registered and unbuffered DIMMs cannot be mixed; the board must support 4Rx4 registered ECC DDR5.

How do I confirm the kit is running at 6400 MT/s with CL52 after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed DDR5-6400 and latency CL52.
