Server-grade DDR4 ECC RDIMM

This 32GB DDR4 2400 ECC Registered VLP DIMM is built for Supermicro SuperStorage 2028R and 6028R series servers. It operates at PC4-19200 speed with CL17 latency and 1.2V power draw. The 2Rx4 registered design ensures signal integrity in multi-DIMM configurations. It will not work in standard desktop computers or alongside unbuffered or load-reduced modules.

Sustained workload stability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption under heavy I/O. The very-low-profile form factor fits dense 1U and 2U chassis without airflow obstruction. JEDEC and RoHS compliance guarantees consistent timing across all qualified Supermicro platforms.

Single-module 32GB capacity

One 288-pin module delivers the full 32GB upgrade, replacing Supermicro part numbers MEMDR432LCL02ER24, MEMDR432LCV01ER24, MEMDR432LCV02ER24, MEMDR432LHL01ER24, MEMDR432LHL02ER24, MEMDR432LSL01ER24, MEMDR432LSL02ER24 and MEMDR432LSV01ER. Buyers needing mixed-rank populations or unbuffered memory must select a different module type.

Questions about this item

How much power does the 1.2V 32GB DDR4 2400 module draw when the server runs all day?

The module operates at 1.2 volts, the standard DDR4 voltage, so power draw stays low even under continuous load in a Supermicro SuperStorage system.

What must the server already have for this VLP 288-pin ECC Registered DIMM to work?

A Supermicro SuperStorage 2028R or 6028R-E1CR12H with free DDR4 RDIMM slots that support 2Rx4 registered ECC memory at 2400 MT/s.

Can I mix this 2Rx4 CL17 stick with the Supermicro MEMDR432LHL01ER24 modules already in my 2028R?

No — the manufacturer highlights state this registered ECC memory cannot be mixed with unbuffered or load-reduced DIMMs; all DIMMs should match capacity, speed and manufacturer.
