Exact-match DDR5-5600 ECC RDIMM kit

This 256 GB kit comprises two 128 GB DDR5-5600 RDIMMs built for the Supermicro X14SRA-T motherboard. Registered ECC architecture with 4Rx4 organisation and CL46 timing matches the board's memory controller requirements. It targets administrators upgrading compatible Supermicro servers that demand registered error-correcting modules at the rated speed.

Installation follows standard RDIMM procedure

Align the 288-pin modules with the keyed slots and press until the retention clips engage; the registered buffer adds slight resistance compared with unbuffered DIMMs. Common issues arise when population order in the manual is ignored or when mixed-rank DIMMs prevent the full 256 GB from being recognised. Verify the approved slot sequence before seating both modules.

4Rx4 registered ECC at 1.1 V decides fit

The combination of 4Rx4 organisation, registered buffering, ECC, and 1.1 V operation is the single specification the X14SRA-T memory controller expects for full-capacity operation. Modules with different rank structure, voltage, or without registration will not be recognised at 256 GB or will fall back to reduced speed. Confirm your platform requires exactly this configuration before ordering.

Questions about this item

How can I confirm the kit is running at DDR5 5600 with CL46 after installing it in the Supermicro X14SRA-T?

Check the BIOS memory information screen or a hardware-monitoring utility such as IPMI; it should report 5600 MT/s and CAS latency 46 for each 128 GB module.

What ships in the box and is anything else required for installation?

The package contains two 128 GB 288-pin DDR5 RDIMMs; no additional parts are needed if the motherboard has free DIMM slots.

Should I choose the 256 GB (2×128 GB) 4Rx4 kit or a different capacity for the X14SRA-T?

Select this 256 GB kit when the board's memory-population guide lists 128 GB 4Rx4 RDIMMs as supported and you want to fill two slots at the rated 5600 MT/s speed.
