8GB DDR4 2666 ECC UDIMM for servers

This 8GB DDR4 2666 ECC UDIMM module is built for servers and workstations that require error-correcting memory. It runs at 1.2V with a CL19 latency and uses a single-rank 1Rx8 organisation on a 288-pin DIMM. The stick is a direct replacement for Dell part numbers A9845650, SNPD715XC/8G and AA335287.

Replaces non-ECC or slower DDR4 DIMMs

Swapping standard unbuffered non-ECC memory for this ECC UDIMM adds single-bit error correction without changing voltage or form factor. The upgrade is worthwhile when the platform supports ECC UDIMM and the workload demands data integrity over raw bandwidth. Systems limited to registered DIMMs cannot use this module.

Suits Dell servers and compatible workstations

Administrators maintaining Dell platforms that specify the listed part numbers will find a drop-in match. Builders whose motherboards require registered RDIMMs, need higher capacities per slot, or run consumer chipsets without ECC support should look at other memory types.

Questions about this item

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

Yes, the module uses the standard 288-pin DDR4 DIMM form factor designed for unbuffered ECC UDIMM slots in compatible servers and workstations.

What is the correct way to seat this 1Rx8 ECC UDIMM so the system recognises the full 8GB?

Align the notch on the module with the slot key, press firmly straight down until both side clips click into place, and verify the 2666 MHz speed in BIOS after boot.

Does the 1.20V DDR4 standard voltage mean I never need to adjust BIOS settings for this RAM?

The module operates at the standard 1.20V DDR4 voltage, so most systems will configure it automatically at 2666 MHz CL19 without manual voltage changes.
