Certified Supermicro Server Memory

This 32GB DDR4 2666MHz ECC RDIMM is built for Supermicro platforms that require registered, dual-rank modules. It operates at 1.2V with CL19 latency and carries the Supermicro MEM-DR432L-HL03-ER26 certification.

Suited for registered DIMM slots only

This module fits servers and workstations that accept 288-pin registered ECC memory. It will not work in systems that require unbuffered UDIMMs or non-ECC memory, so buyers needing standard desktop RAM should look elsewhere.

Verify registered ECC support first

Check that your motherboard and BIOS list 288-pin RDIMM support with ECC registered operation at 2666MHz. Confirm the platform accepts 2Rx4 dual-rank modules and 1.2V DDR4 voltage before ordering.

Questions about this item

Does my motherboard need 288-pin DDR4 RDIMM slots to install this 32GB module?

Yes, this module uses the 288-pin RDIMM form factor and requires DDR4 RDIMM slots on a compatible server or workstation motherboard.

Can I mix this 2666MHz ECC Registered DIMM with older DDR4 ECC modules running at a lower speed?

The system will typically downclock all modules to the lowest common speed, but mixing registered and unbuffered ECC DIMMs is not supported.

How can I confirm the module is running at 2666MHz with ECC active after installation?

Check the memory speed and ECC status in your BIOS/UEFI or use a system information tool such as dmidecode or CPU-Z to verify 2666MHz operation and ECC Registered mode.
