Exact-match DDR5-5600 ECC RDIMM kit

This 256GB kit contains two 128GB DDR5-5600 (PC5-44800) Registered ECC modules built to the precise 4Rx4 rank, 1.1V voltage and CL46 timing the Supermicro X14SDV-36C-SP3F motherboard expects. The 288-pin RDIMM form factor matches the board's physical slots so the memory controller recognises full capacity at rated speed without down-clocking or population errors.

Registered ECC limits for full-slot operation

Registered buffering offloads the memory controller so every populated slot runs at the full 256GB capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The DDR5-5600 standard caps transfer rate at 5600 MT/s and the fixed 4Rx4 organisation means this kit cannot be mixed with modules of different rank or voltage without losing stability or registered benefits.

Verify board population rules before ordering

The Supermicro X14SDV-36C-SP3F manual lists supported capacities, approved DIMM population order and any BIOS version requirements that are not covered by the kit specifications. Confirm the board accepts 4Rx4 Registered RDIMMs at 1.1V and that your chassis provides the 288-pin DDR5 slots this form factor requires.

Questions about this item

Should I choose the 2x128GB kit or a different capacity for my Supermicro X14SDV-36C-SP3F?

The 2x128GB kit provides 256GB total and matches the board's DDR5 5600 RDIMM requirements. Verify your motherboard manual for approved DIMM population order and maximum supported capacity before ordering.

What does the DDR5 5600 speed mean once installed in the server?

The modules run at 5600 MT/s (PC5-44800) with CL46 latency at 1.1V. Registered buffering lets every slot operate fully populated at this rated speed without downclocking.

How does the 288-pin RDIMM interface and ECC affect real-world operation?

The 288-pin RDIMM form factor fits only RDIMM slots on the Supermicro X14SDV-36C-SP3F. ECC corrects single-bit errors automatically while registered architecture reduces electrical load on the memory controller.
