32 GB DDR4-2400 ECC RDIMM for servers

This module delivers 32 GB of registered DDR4 memory rated at 2400 MT/s with ECC protection. The dual-rank 2Rx4 organisation and CL17 latency suit multi-socket platforms that require error correction and signal integrity under sustained load.

Upgrade from smaller RDIMMs or non-ECC memory

Replacing lower-capacity registered DIMMs with this 32 GB stick increases density per channel, reducing the total module count needed for a given memory footprint. The step is worthwhile when the platform supports DDR4-2400 registered ECC and the workload benefits from higher capacity without exceeding the memory controller’s rank limits.

Fits DDR4 RDIMM slots with ECC support

Installation requires a server motherboard that accepts registered DDR4 ECC DIMMs and can operate at 2400 MT/s with CL17 timing. The registered buffer reduces electrical loading on the memory bus, freeing the controller to populate more slots per channel while maintaining stability.

Questions about this item

Will this 2400 MHz DDR4 RDIMM fit a standard 288-pin server slot?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor for server motherboards.

Do I need to configure anything in BIOS after installing this ECC registered DIMM?

Most server platforms detect the 2Rx4 organisation and 17 latency automatically; just ensure ECC is enabled in BIOS.

How can I tell when this 32 GB module should be replaced?

Run periodic memory diagnostics; replace the stick if correctable ECC error counts rise or uncorrectable errors appear.
