NEMIX 8GB DDR4 ECC RDIMM

This NEMIX RAM module provides 8GB of DDR4 2666 ECC registered memory for compatible Hynix servers and workstations. It operates at 1.2V with CL19 latency and uses a 1Rx8 chip organisation. The 288-pin RDIMM form factor fits registered DIMM slots in supported enterprise systems.

Installation and common issues

The module installs in standard 288-pin DDR4 RDIMM slots and the manufacturer notes that upgrades typically take a few minutes. Always consult the system manual for the correct slot population order and maximum supported capacity. A frequent issue occurs when mixing registered ECC modules with unbuffered non-ECC memory, which prevents the system from booting.

Pre-order checks

Verify that your server or workstation specifically requires DDR4 2666 ECC registered RDIMM modules and supports 1Rx8 rank configuration. Confirm the motherboard accepts 1.2V operation and that the BIOS is updated to recognise the module capacity. Ensure the chassis has enough clearance for the bare module, as no heat spreader is included.

Questions about this item

How can I confirm the 8 GB DDR4-2666 ECC RDIMM is running at CL19 after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 2666 MT/s with CAS latency 19; the module will also show as registered ECC.

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

The box contains one 8 GB 288-pin DDR4-2666 ECC registered DIMM (1Rx8, 1.2 V); no cables, brackets or additional parts are included.

Should I choose the 1Rx8 version or look for a different rank configuration?

This module is a single-rank 1Rx8 design; select it when your server or workstation requires a 1Rx8 registered ECC DIMM at 2666 MT/s.
