Server ECC RDIMM upgrade

This 16GB DDR4 2400MHz registered DIMM adds ECC error correction to Supermicro motherboards K1SPE K1SPi X10DAC X10DAi and X10DAL-i. It runs at PC4 19200 with CL17 latency and 1.2V operation. The module is built for server and workstation workloads that require data integrity.

Simple slot installation

Align the 288-pin edge connector with the motherboard DIMM slot and press until the retention clips click. The registered buffer adds electrical load so the board must support registered memory. Mixing this module with unbuffered DIMMs will prevent the system from posting.

Verify registered ECC support

Check that your Supermicro board lists registered ECC RDIMMs in its qualified vendor list. The CPU and chipset must both support ECC and registered operation. Systems that only accept unbuffered non-ECC memory cannot use this upgrade.

Questions about this item

How do I confirm the 16GB DDR4 2400MHz CL17 RDIMM is running at PC4-19200 after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 2400 MT/s with CL17 timings at 1.2V; the module will report as ECC Registered and 2Rx8 in the SPD table.

What ships with the OWC 2R4D42R816GB module and what must I source separately?

The box contains the single 16GB 288-pin DDR4 ECC Registered RDIMM; no heat spreader, cables or tools are included, and any additional DIMMs for multi-channel population must be purchased separately.

Which capacity and rank option should I choose for a Supermicro X10DAi that supports 2Rx8 Registered ECC?

Select this 16GB 2Rx8 DDR4-2400 CL17 Registered ECC RDIMM; it matches the Supermicro part numbers MEMDR416LCL06ER24, MEMDR416LHL03ER24 and MEMDR416LSV01ER24 listed for the X10DAi, K1SPE, K1SPi, X10DAC and X10DAL-i boards.
