  • ECC UDIMM corrects single-bit errors automatically
  • Single-rank 1Rx8 layout simplifies memory channel population
  • 2 V operation matches standard DDR4 voltage

Server DDR4 ECC UDIMM

This 8 GB DDR4 2666 MHz module uses ECC Unbuffered DIMM technology with a single rank x8 organisation. It targets administrators upgrading compatible servers or workstations that specifically require 288-pin ECC UDIMM memory. Desktop and laptop systems cannot use this module.

ECC error correction

The ECC Unbuffered design detects and corrects single-bit memory errors without adding registered buffering latency. This improves data integrity for workloads that demand consistent accuracy while keeping timing at CL19 and standard 1.2 V operation.

Straightforward DIMM installation

The 288-pin DIMM seats in standard DDR4 UDIMM slots following the motherboard manual channel population rules. Common issues arise when the platform expects registered DIMMs or a different rank configuration, so verify the memory specifications before installing.

Questions about this item

Will the CL19 timing require any adjustment or replacement as the server ages?

The module runs at a fixed CL19 latency; no timing changes or replacement are needed during its service life.

What limit appears first when this ECC UDIMM runs at 2666 MHz continuously?

The 1.2 V operating voltage and single-rank design keep thermal output low, so the DDR4 2666 speed ceiling is reached before any thermal throttle.

How much heat and noise does the 1Rx8 1.2 V module add during all-day operation?

At standard 1.2 V the stick produces minimal heat and has no moving parts, so it adds no audible noise to the chassis.
