32GB DDR4 LRDIMM module

This is a 32GB DDR4 LRDIMM module built for Dell PowerEdge and Precision Workstation servers. It operates at 2133MHz with a 1.20V supply and uses a 288-pin registered ECC design. The part number is A7910489 and the standard is DDR4-2133/PC4-17000.

Suitable for compatible Dell servers only

This module suits administrators upgrading or repairing the listed PowerEdge and Precision Workstation models such as the R630, R730, T630 or T7910. It is not for desktop PCs, laptops or non-Dell servers that require unbuffered or standard RDIMM memory. Buyers needing different capacities, speeds or form factors should look elsewhere.

Registered ECC LRDIMM form factor

The registered ECC LRDIMM form factor is the single specification that decides fitment. Only systems qualified for load-reduced registered DDR4 DIMMs at this voltage and pin count will accept it. Verify the exact model against the supported list before purchase.
