32GB DDR4 2400MHz ECC Registered RDIMM

This 32GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It uses a 2Rx4 dual-rank layout and Micron chipset for registered ECC performance. The 288-pin RDIMM form factor fits server and workstation platforms that require registered memory. Buyers who need unbuffered UDIMM modules for consumer desktop boards cannot use this product.

Supermicro Certified 288-Pin RDIMM

Certified as Supermicro MEM-DR432L-CL02-ER24, this module validates directly against qualified vendor lists for supported Supermicro systems. The registered buffer reduces electrical load on the memory controller, freeing the platform to populate more DIMM slots per channel. Builders must confirm their motherboard accepts registered ECC DDR4 before installation.

Standard Voltage DDR4 Thermals

Operating at the DDR4 standard voltage of 1.20V keeps power draw and heat output within JEDEC limits for dense server configurations. Registered buffering adds minimal latency while improving signal integrity across fully populated channels. The module relies on system airflow for cooling; no active cooling is included.

Questions about this item

Does the 1.2V DDR4 voltage limit how long the module can run at full 2400MHz speed under sustained load?

The module operates at standard 1.20V DDR4 voltage, which is the JEDEC specification for 2400MHz operation and does not impose a thermal or power limit that would throttle sustained performance.

How much heat and noise does the registered ECC design add when the server runs continuously?

Registered DIMMs include an onboard register that adds negligible power draw and no moving parts, so the module itself produces no noise and only minimal additional heat compared with unbuffered memory.

What motherboard feature must my system already have to use this 2Rx4 RDIMM?

Your motherboard must support DDR4 registered ECC memory with 288-pin RDIMM slots and be qualified for dual-rank 2Rx4 modules.
