4GB DDR4 2133 ECC RDIMM for Servers

This 4GB DDR4 2133 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1.2V with a CAS latency of 15 and uses a single-rank x8 organisation. The module is not compatible with standard desktop or laptop computers.

Upgrade from non-ECC or lower-capacity modules

The jump is worth it when your workload demands data integrity through ECC and the platform requires registered DIMMs. Adding this module increases the memory pool for virtualisation, database or compute tasks where single-bit error correction prevents silent data corruption. Systems that only accept unbuffered memory cannot use this module.

Straightforward 288-pin DIMM installation

Align the notch on the 288-pin module with the slot key, press firmly until the retention clips lock, and follow the system manual for channel population rules. Common issues include mixing registered and unbuffered DIMMs, exceeding the maximum rank count per channel, or installing in unsupported desktop boards that physically accept the module but will not POST.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 DIMM form factor and 1.2 V voltage, so it fits any server or workstation slot designed for DDR4 registered ECC memory.

Do I need to populate specific channels or follow a sequence when installing this single-rank ECC RDIMM?

Install the module in the slot order shown in your system manual; the common mistake is placing a single module in the wrong channel, which can prevent the server from posting.

How do I know when this 4 GB ECC registered module should be replaced?

ECC corrects single-bit errors automatically; if your system logs show uncorrectable errors or repeated correctable-error thresholds being exceeded, plan a replacement.
