Server-grade DDR4 for Supermicro F618R2

This 32GB DDR4 2400 ECC registered DIMM is built for Supermicro SuperServer F618R2 series systems. It delivers 32GB of 2400 MT/s memory in a single 288-pin VLP module operating at 1.2V. The 2Rx4 organisation and CL17 latency suit multi-socket server boards that require registered memory with error correction. Standard desktop platforms cannot use this module.

Sustained throughput with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing the module to maintain stable 2400 MT/s transfer rates under continuous multi-threaded workloads. ECC detects and corrects single-bit errors in real time, preventing data corruption during long compute jobs or virtualisation tasks. The 2Rx4 rank structure supports high-density population across all DIMM slots without exceeding the platform's electrical limits.

Replaces Supermicro MEMDR432L series DIMMs

This module directly substitutes Supermicro part numbers MEMDR432LCL02ER24, MEMDR432LCV01ER24, MEMDR432LCV02ER24, MEMDR432LHL01ER24, MEMDR432LHL02ER24, MEMDR432LSL01ER24, MEMDR432LSL02ER24 and MEMDR432LSV01ER. The upgrade is worthwhile when expanding total system memory beyond the factory configuration or when replacing failed modules in deployed F618R2 chassis. It cannot be mixed with unbuffered or load-reduced DIMMs.

Questions about this item

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

The module operates at 1.2 V, the standard DDR4 voltage, so power draw stays low even under 24/7 server workloads.

Which Supermicro SuperServer models must I already own for this 32 GB ECC registered DIMM to work?

It is validated for Supermicro SuperServer F618R2-RC1+, F618R2-RC1PT+, F618R2-RT+, F618R2-RTN+ and F618R2-RTPT+.

Can I mix this 2Rx4 CL17 registered stick with the unbuffered ECC DIMMs currently in my F618R2-RC1+?

No, registered memory cannot be mixed with unbuffered or load-reduced ECC modules; all slots must use the same registered type.
