NEMIX RAM 16GB DDR4 2666 ECC UDIMM CL19 2Rx8 memory upgrade

SKU CH-A38W-1P8F3

16 GB DDR4 2666 ECC UDIMM module with CL19 latency for workstation memory upgrades

  • Total capacity16 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL19
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • 16 GB capacity expands workstation memory headroom
  • DDR4 2666 speed delivers high data throughput
  • ECC protection detects and corrects memory errors
  • Unbuffered UDIMM design fits standard desktop slots
  • 2 V operation reduces power consumption

Hynix-Compatible ECC UDIMM

This 16 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.20 V operation. It targets workstations and servers that require error-correcting unbuffered memory for stable operation. The single stick simplifies capacity scaling in supported Hynix platforms.

288-pin unbuffered design

The 2Rx8 organisation fits standard DDR4 UDIMM slots without registered buffering. No heat spreader is fitted, keeping the profile low for dense server chassis or compact workstation boards. ECC circuitry protects data integrity during sustained workloads.

Upgrade from non-ECC or smaller kits

Replacing standard unbuffered DIMMs adds single-bit error correction for mission-critical tasks. The jump is worthwhile when your motherboard supports ECC UDIMM and you need 16 GB per slot at 2666 MHz. Systems limited to lower speeds or non-ECC memory cannot use this module.

Questions about this item

What DDR4 speed and peak bandwidth does this module run at?

This module operates at DDR4 2666 with a PC4-21300 peak transfer rate.

Does the 288-pin UDIMM need a heat spreader or extra clearance?

No heat spreader is fitted; the bare PCB fits standard DDR4 slots without additional height clearance.

How do I install the ECC UDIMM, and what step is often missed?

Power off the system, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then enable ECC in the BIOS — the step many skip.
