Exact-fit DDR5 kit for Supermicro X14SRA-F

This 256 GB kit delivers two 128 GB DDR5-5600 registered ECC RDIMMs built to the memory controller's exact rank, voltage and timing requirements. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Registered architecture with on-die ECC

Each 288-pin RDIMM uses a 4Rx4 organisation and operates at 1.1 V, offloading the memory controller so every slot stays stable when fully populated. On-die ECC corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

Replaces mismatched or capacity-limited DIMMs

The jump is worth it when a server shows memory errors, refuses to boot with mixed ranks, or cannot reach the installed memory ceiling. Buyers who need unbuffered UDIMMs, SODIMM form factors, or non-ECC modules should look elsewhere.

Questions about this item

What does the PC5-44800 rating mean for the DDR5 5600 speed on this kit?

PC5-44800 is the JEDEC standard name for DDR5 5600 MT/s, so the modules are specified to run at 5600 MT/s with CL46 timing at 1.10V.

What physical slot and form factor do these 128GB modules need on the Supermicro X14SRA-F?

They require standard 288-pin DDR5 RDIMM slots; the board must accept registered ECC DIMMs, not UDIMM or SODIMM.

What is the correct population order for the 2x128GB kit on the X14SRA-F, and what step is often missed?

Follow the motherboard manual for the approved DIMM sequence, then seat each RDIMM until the ejectors click — the step often missed is verifying both latches lock fully.
