8GB DDR4 2666 ECC RDIMM

This 8GB DDR4 2666 ECC RDIMM module adds registered error-correcting memory to compatible servers and workstations. It runs at 1.2V with CL19 timing in a 288-pin DIMM form factor. The single-rank 1Rx8 organisation uses Samsung chips for stable operation under sustained workloads.

Upgrade from non-ECC or slower DDR4

Replaces unbuffered or lower-speed DDR4 modules when data integrity and registered signalling are required by the platform. The jump is worthwhile when the system board specifies registered ECC memory and the workload demands corrected single-bit errors without interruption.

Suits servers needing registered ECC

Ideal for administrators expanding memory in qualified server or workstation chassis that mandate registered ECC DIMMs. Not suitable for desktop boards that accept only unbuffered non-ECC memory or for builds requiring higher capacities per slot than 8GB.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's DIMM slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor required for registered server memory slots.

What is the correct way to seat this ECC RDIMM so the register engages?

Align the notch with the slot key, press straight down evenly until both side clips click, confirming the registered buffer is fully seated.

When should I expect to replace this 1.20V Samsung-chip module?

DDR4 server memory typically runs for the life of the platform; replace only if diagnostics report uncorrectable ECC errors.
