Server ECC UDIMM 8 GB DDR4 2133 MHz

This 8 GB DDR4 ECC UDIMM module runs at 2133 MHz with CL15 latency and 1.2 V operation. It uses a single-rank 1Rx8 organisation on a 288-pin DIMM form factor. The module is built specifically for servers and workstations that require error-correcting unbuffered memory.

DDR4 ECC UDIMM practical limits

The DDR4 2133 MHz standard tops out at the PC4-17000 data rate and requires a platform that supports ECC unbuffered DIMMs. Desktop and laptop motherboards cannot use this module because they lack the necessary memory controller and BIOS support. Mixing with non-ECC or registered DIMMs will prevent the system from posting.

Installation notes for 288-pin ECC UDIMM

Align the notch on the module with the key in the 288-pin slot and press firmly until both retention clips engage. Common issues include inserting the module into a consumer board that disables ECC, populating slots in the wrong channel order, and failing to update the system BIOS to recognise the new capacity.

Questions about this item

Should I choose the 8 GB single-rank module or look for a dual-rank alternative?

This module is a single 8 GB stick organised as 1Rx8, so it presents one rank to the memory controller; dual-rank options would show two ranks per DIMM and may allow higher total capacity per channel on some platforms.

What does the 2133 MHz rating deliver once the module is installed in a server?

The module runs at DDR4 2133 MHz (PC4-17000) with CL15 latency at 1.2 V, giving the bandwidth and timing the platform negotiates for ECC UDIMM operation.

How does the DDR4 ECC UDIMM 288-pin interface limit what I can use this with?

The 288-pin DDR4 ECC unbuffered DIMM fits only server and workstation boards that explicitly support DDR4 ECC UDIMM; it will not work in desktop or laptop slots.
