Server-grade ECC RDIMM for Supermicro

This 32GB DDR4 2400MHz CL17 registered module is built for Supermicro motherboards K1SPE, K1SPi, X10DAC, X10DAi and X10DAL-i. It delivers error-correcting, buffered memory required by workstation and server platforms. Standard desktop systems cannot use this module.

ECC registered design changes compatibility

The registered buffer and ECC circuitry alter electrical loading on the memory bus, so this DIMM must not be mixed with unbuffered memory. It replaces Supermicro part numbers including MEM-DR432LC-ER24 and MEMDR432LHL02ER24, ensuring drop-in validation for the listed boards.

32GB single-module capacity at 1.2V

One 288-pin 2Rx4 DIMM provides 32GB of PC4-19200 bandwidth for virtualization, database or NAS workloads. Headroom scales with available DIMM slots on the target motherboard; buyers needing more than the board's maximum supported memory must add modules rather than exceed the platform limit.

Questions about this item

Will the 2Rx4 rank layout or registered buffer need any firmware updates on a Supermicro X10DAi?

The module is a 2Rx4 registered ECC DIMM tested for the listed Supermicro boards; no separate firmware is required for the memory itself.

What limits sustained throughput on this DDR4 2400 CL17 kit?

The JEDEC PC4-19200 2400 MT/s rating and CL17 latency set the maximum sustained bandwidth.

How much heat and power does a 32 GB 1.2 V registered DIMM produce in a server running 24/7?

At 1.2 V the module draws minimal power and has no heat spreader, so airflow across the PCB keeps temperatures low.
