4 GB DDR4 2133 ECC UDIMM module

This 4 GB DDR4 2133 MHz ECC unbuffered DIMM uses a single-rank 1Rx8 organisation and runs at 1.20 V with CL15 latency. It is built with major-brand chips and carries a 288-pin form factor for server and workstation platforms. The module is validated as a direct replacement for IBM-Lenovo part numbers 46W0808, 46W0809, 4X70G88315 and 4X70K14183.

Suited for ECC-capable servers needing

This module fits systems that accept DDR4 ECC UDIMMs at 2133 MHz and require only 4 GB per slot. It is not for builds that need registered or load-reduced memory, higher densities per module, faster DDR4 speeds or non-ECC consumer DIMMs. Buyers whose platforms demand RDIMM, LRDIMM or capacities above 4 GB should look elsewhere.

Steady throughput under continuous server workloads

ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long-running compute or virtualisation tasks. The 1.20 V standard voltage keeps power draw predictable when all slots are populated. Unbuffered topology adds minimal latency, so sustained bandwidth remains consistent without the registration delay of RDIMMs.

Questions about this item

What motherboard slot does this 288-pin DDR4 UDIMM need?

It fits a standard DDR4 UDIMM slot on a server or workstation board that accepts 1.20V ECC unbuffered memory at 2133 MHz.

Will this CL15 1Rx8 module run with existing DDR4 2133 ECC UDIMMs in the same system?

Yes, it will operate at the common 2133 MHz speed and 1.20V voltage, though the memory controller will use the slowest timing among installed modules.

How can I confirm the module is detected at 2133 MHz with ECC active after installation?

Check the BIOS memory information or run a hardware utility such as CPU-Z; both should show 2133 MHz, 4 GB capacity, and ECC enabled.
