Server DDR4 ECC UDIMM

This 8 GB DDR4 module runs at 2666 MT/s with CL19 latency and operates at 1.2 V. It is an unbuffered ECC UDIMM built for servers and NAS devices that require error-correcting memory without registered signalling.

288-pin DDR4 slot requirement

The stick fits a standard 288-pin DDR4 DIMM socket and needs a platform that supports unbuffered ECC UDIMMs at the PC4-21300 data rate. It frees a second slot for future expansion because the capacity is delivered in a single rank of 2Rx8 chips.

Low-voltage operation

At 1.20 V the module draws minimal power and runs cool without a heat spreader. The absence of a spreader keeps the profile low for tight server chassis, while ECC operation adds only a small overhead to normal system thermals.

Questions about this item

Does the CL19 latency become a bottleneck during sustained 2666 MT/s workloads?

CL19 is the rated latency at 2666 MT/s; the module runs at this timing continuously under load.

How much heat does the 1.2 V unbuffered ECC UDIMM generate when running all day?

At 1.20 V with no heat spreader, the module produces only modest warmth and relies on normal chassis airflow.

What motherboard slot and chipset support are required for this 288‑pin DDR4 ECC UDIMM?

A 288‑pin DDR4 UDIMM slot with ECC support in the chipset or CPU is needed; the module uses major OEM Samsung, Micron or Hynix chips.
