Server memory kit for Supermicro X14SRA-F

This 256 GB kit contains four 64 GB DDR5 RDIMMs rated at 5600 MHz with CL46 latency and 1.1 V operation. Registered ECC architecture ensures data integrity and full-capacity operation when all slots are populated on the specified Supermicro motherboard.

Installation notes and common issues

The modules use the standard 288-pin RDIMM form factor required by the X14SRA-F; they are not compatible with UDIMM or SODIMM slots. Verify the motherboard manual for approved population order and maximum supported capacity per channel before fitting all four sticks.

Suited for memory-bound server workloads

Ideal for administrators expanding a Supermicro X14SRA-F system to its full registered ECC capacity with matched rank and voltage. Not suitable for consumer desktops, workstations requiring unbuffered memory, or any platform that does not support DDR5 RDIMM modules.

Questions about this item

How do I verify the kit is running at DDR5 5600 CL46 after installing it in my Supermicro X14SRA-F?

Enter the BIOS or use a hardware monitoring tool and confirm the memory frequency shows 5600 MT/s with timings at 46-46-46 and voltage at 1.10 V across all four slots.

What exactly ships in the box and do I need any extra brackets or cables?

The box contains four 64 GB DDR5 288-pin ECC Registered RDIMM modules for a total of 256 GB; no brackets, cables or additional parts are required.

Should I choose the 2Rx4 64 GB modules or a different rank for this motherboard?

The Supermicro X14SRA-F memory population rules call for 2Rx4 Registered ECC DIMMs, so this 4 x 64 GB kit matches the required rank and capacity per slot.
