32GB ECC Registered DDR4 Module

This 32GB DDR4 2400MHz CL17 RDIMM is built for Supermicro X10DR series motherboards including X10DRFF-ITG, X10DRFR, X10DRG-H, X10DRH-C and X10DRFR-T. It delivers error-correcting registered memory for servers, workstations and NAS systems that require 288-pin ECC RDIMM modules.

Thermals and Power Draw

Operating at 1.2V, the module runs at standard DDR4 voltage without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation in multi-DIMM server configurations.

Build and Compatibility Notes

The 2Rx4 rank organisation and registered design mean this DIMM cannot be mixed with unbuffered memory and will not fit standard desktop platforms. It replaces multiple Supermicro part numbers such as MEM-DR432LC-ER24 and MEMDR432LCL01ER24 for direct upgrade paths.

Questions about this item

How do I install this 288-pin DDR4 ECC RDIMM in a Supermicro X10DRG-H, and what step is often missed?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both latches click, then verify in BIOS that the 32GB capacity and 2400 MT/s speed are recognised; the step often missed is confirming the registered ECC type matches the board requirement and not mixing with unbuffered DIMMs.

What maintenance or replacement will this 32GB DDR4 2400 CL17 module need over its service life?

No scheduled maintenance is required; if a module fails it is replaced as a unit under the limited lifetime warranty, and the only ongoing care is keeping the server air filters clean so the 1.2V DIMMs stay within thermal limits.

What limit appears first when this 2Rx4 registered DIMM runs sustained workloads at 2400 MT/s?

The memory controller’s maximum supported capacity per channel and the 17-cycle CAS latency set the practical throughput ceiling before thermal throttling becomes a factor on these 1.2V modules.
