Server DDR4 16 GB module

This 16 GB DDR4 ECC UDIMM runs at 2933 MHz with CL21 latency and 1.2 V operation. It is built for servers and workstations that require error-correcting unbuffered memory. The dual-rank 2Rx8 organisation fits standard 288-pin DIMM slots. Desktop and laptop systems are not supported.

Replaces non-ECC or lower-capacity sticks

Swapping standard unbuffered DIMMs for this ECC module adds data-integrity protection for critical workloads. The jump is worth it when your platform explicitly lists DDR4 2933 MHz ECC UDIMM support and you need 16 GB per slot. Systems limited to registered memory or lower speeds cannot use this module.

Installs in standard 288-pin slots

Align the notch, press evenly until the latches click, then follow the system manual for channel population order. Common issues arise when mixing ranks or speeds across channels, or when the BIOS does not recognise the 2Rx8 configuration. Verify supported memory specifications before installation.

Questions about this item

Will this 288-pin DDR4 UDIMM fit in my server's standard DIMM slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and 1.2V voltage required by compatible server and workstation motherboards.

What is the correct way to seat this dual-rank ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the system recognises the full 16GB and ECC function in BIOS.

When should I expect to replace this 2933 MHz CL21 memory?

DDR4 ECC UDIMMs have no moving parts and typically last the life of the server; replace only if memory diagnostics report correctable or uncorrectable errors.
