8GB DDR4 ECC UDIMM for servers and workstations

This 8GB DDR4 module runs at 2133 MHz with CL15 latency and 1.2V operation. It is built as a 2Rx8 dual-rank unbuffered DIMM with 288 pins for server and workstation platforms that require ECC memory. Desktop and laptop systems are not supported.

Straightforward DIMM installation

The module seats in a standard 288-pin DDR4 slot and requires no special tools or configuration beyond the system memory seating and channel guidelines in the server or workstation manual. Problems usually arise when the platform does not support ECC unbuffered memory or when population rules for dual-rank modules are ignored.

Verify ECC unbuffered DDR4 support before ordering

Check the system documentation to confirm the platform accepts DDR4 ECC UDIMM modules at 2133 MHz and can address 2Rx8 dual-rank sticks. Ensure the memory channel layout matches the module rank configuration and that the BIOS or firmware is current enough to recognise the module.

Questions about this item

How can I confirm the module is running at CL15 after installation?

Check the BIOS memory timing table or a tool such as CPU-Z; the SPD should show CAS 15 at 2133 MHz.

What comes in the package and what must I source separately?

The box contains one 8 GB DDR4 2133 MHz ECC UDIMM 288-Pin module; no cables, brackets or additional parts are included.

Which capacity and rank should I choose for a dual-channel server board?

Select the 8 GB 2Rx8 module and populate matching slots per the motherboard manual to enable dual-channel operation.
