Exact-match DDR5-5600 server upgrade

This 128GB DDR5 5600MHz PC5-44800 Registered ECC RDIMM is built for the Supermicro X14SDV-36C-SP3F motherboard. It delivers the precise 4Rx4 rank structure, 1.1V operating voltage and CL46 latency the board's memory controller expects for full-capacity recognition at rated speed.

Registered architecture and 288-pin form factor

The registered (buffered) design offloads the memory controller so every populated slot runs stably at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots — not UDIMM or SODIMM sockets — and the modules ship without heat spreaders.

Verify your configuration before ordering

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. This kit provides a single 128GB module; confirm the maximum per-slot capacity and total system limit your platform allows.

Questions about this item

Does this DDR5-5600 RDIMM run at 5600 MHz when installed in the Supermicro X14SDV-36C-SP3F?

Yes, the module is spec-matched to the board's DDR5-5600 (PC5-44800) memory controller so it will be recognised at its full 5600 MT/s rated speed.

What physical slot does this 288-pin registered DIMM require?

It fits a standard 288-pin DDR5 RDIMM socket; the board must accept registered ECC DIMMs, not UDIMM or SODIMM slots.

What population order should I follow when installing this 4Rx4 kit?

Consult the Supermicro X14SDV-36C-SP3F manual for the approved DIMM population sequence and install modules in the exact slots listed.
