4GB DDR4 2133MHz ECC UDIMM Server Module

This 4GB DDR4 ECC UDIMM module runs at 2133MHz with CL15 latency and 1.20V operation. It is built for servers and workstations that require error-correcting unbuffered memory. The single-rank 1Rx8 design uses major-brand chips on a 288-pin DIMM. It serves administrators upgrading or repairing compatible Dell platforms.

Capacity and headroom for light workloads

Four gigabytes provides enough space for basic OS tasks, single-threaded services, or entry-level virtualisation hosts. The 2133MHz speed and ECC protection maintain data integrity under sustained loads. Headroom runs out quickly with multiple VMs, large databases, or memory-intensive applications that exceed the module's capacity.

Replaces Dell A8661095 and SNPN8MT5C/4G

This module is a direct equivalent for the Dell part numbers listed, letting you restore original capacity or add a matching stick to an empty slot. The jump is worth it when a failed DIMM causes errors or when a single-channel configuration limits throughput. Systems needing higher density or registered memory must use different modules.

Questions about this item

Will this DDR4 2133MHz ECC UDIMM run alongside my existing DDR4 2133MHz ECC UDIMM modules?

Yes, if your current modules are also DDR4 2133MHz ECC UDIMM at 1.2V with CL15 timing, they will operate together at the lowest common speed and voltage.

How can I confirm the module is detected and ECC is active after installation?

Enter the system BIOS or UEFI and verify the memory shows 4GB at 2133MHz with ECC enabled; run a memory diagnostic such as MemTest86 to confirm error-correction function.

Does the package contain only the 288-pin DIMM or are extra parts included?

The box contains the single 4GB DDR4 2133MHz ECC UDIMM module only; no additional cables, brackets or tools are supplied.
