32GB DDR4 2400MHz ECC RDIMM

This 32GB DDR4 2400MHz ECC Registered DIMM is built for Supermicro X11SDS and X11SDV server motherboards. It operates at 1.2V with CL17 latency and a 2Rx4 rank configuration. The module uses a 288-pin interface and contains error-correcting code for data integrity.

Server and workstation upgrades only

This memory suits administrators upgrading compatible Supermicro X11SDS-8C, -12C, -14C, -16C or X11SDV-12C-TLN2F systems. It will not work in standard desktop computers or consumer laptops. Builders needing unbuffered non-ECC modules should look elsewhere.

Registered ECC with 2Rx4 organisation

The single deciding specification is the Registered ECC 2Rx4 organisation, which must match the motherboard memory controller. Mixing this module with unbuffered memory will prevent the system from booting. Verify the Supermicro part number list before purchase.

Questions about this item

How much power does the 1.2V DDR4 2400MHz module draw when the server runs continuously?

At 1.2V the 32GB DDR4 2400MHz ECC RDIMM operates at standard DDR4 voltage, so power draw stays within normal DDR4 limits during all-day server workloads.

Which motherboard must I already have for this 288-pin ECC RDIMM to work?

It is validated for Supermicro X11SDS-12C, X11SDS-14C, X11SDS-16C, X11SDS-8C and X11SDV-12C-TLN2F motherboards; the board must support DDR4 ECC Registered memory.

Can I add this CL17 2Rx4 module alongside the Supermicro MEM-DR432LC-ER24 sticks already in my system?

Yes, it replaces Supermicro part numbers including MEM-DR432LC-ER24, MEMDR432LCL01ER24 and MEMDR432LSV01ER24, so it will run with those existing modules.
