Compatible DDR5 upgrade for Dell OptiPlex

This 16GB DDR5 4800 module is built for Dell OptiPlex 7000 Tower, 7010 SFF Plus, 7010 Tower Plus and XE4 Tower systems. It delivers a JEDEC-standard PC5-38400 speed at 1.1V with CL40 latency in a single unbuffered UDIMM. The upgrade is designed for owners of these specific desktops who want a straightforward capacity increase.

Suitable for listed OptiPlex desktops only

The module fits the four OptiPlex models named above and replaces Dell part numbers AB883074, AC027075, SNPG00XJC/16G and SNPK7G24C/16G. Builders using any other motherboard, laptop, workstation or server platform should look elsewhere because the pin-out, voltage and SPD programming are tailored to these systems.

16GB capacity in a single 1Rx8 UDIMM

Each stick provides 16GB organised as one rank by eight chips on a 288-pin DDR5 UDIMM. This density means one slot adds 16GB without mixing ranks, which is the deciding factor when the board has limited slots or requires single-rank population rules.

Questions sur cet article

Will the 1Rx8 rank layout ever need to be changed or the module replaced?

The module is a single 16 GB 1Rx8 DDR5 UDIMM; no internal components are serviceable, so replacement would only be needed if the stick itself fails.

What limit appears first when the memory runs continuously at 4800 MT/s CL40?

The JEDEC-standard 1.1 V operating voltage and CL40 latency define the sustained performance envelope; the module has no heat spreader, so thermal headroom is set by the system's airflow.

How much heat or noise does the bare 288-pin DIMM add during all-day operation?

With no heat spreader and a low 1.1 V DDR5 design, the module produces minimal extra heat and adds no audible noise; system fan behaviour depends on the OptiPlex chassis.
