16 GB DDR4 2666 MHz ECC registered server memory, Dell A9810562 compatible, 2Rx8 1.2 V 288-pin, 100 % tested
This 16GB DDR4-2666 registered ECC module is built for servers and workstations that require error-correcting memory. It operates at 1.2V with a 2Rx8 rank configuration across 288 pins. The module uses major-brand chips from Samsung, SK Hynix or Micron. It is validated as 100 percent compatible with Dell systems carrying part number A9810562.
The module serves as a direct replacement for Dell A9810562 memory at more than 60 percent off OEM pricing. It maintains the original factory warranty because it originates from the same manufacturers used for OEM branded modules. The jump is worth it when expanding capacity or replacing failed sticks in supported Dell servers without paying OEM list prices. All orders ship with identically matched modules to avoid mixing revisions.
This memory suits IT teams extending the life of existing Dell infrastructure that accepts DDR4-2666 registered ECC DIMMs. It is not for desktop PCs or consumer motherboards that only accept unbuffered non-ECC memory. Buyers who need different speeds, capacities or form factors should look at other modules. Systems requiring registered ECC DDR4 in a 288-pin package at this speed and voltage will find a tested, warranted match here.

Align the notch with the slot key, press firmly until both retention clips click, and verify the 2Rx8 rank registers in BIOS.
Replace if memory diagnostics report uncorrectable ECC errors or if the server logs recurring corrected-error thresholds.
