Dell OptiPlex 3080 and 3090 Memory

This 8GB DDR4 UDIMM is built for Dell OptiPlex 3080 SFF, 3080 Tower, 3090 SFF, 3090 Tower and XE3 systems. It delivers a straightforward capacity increase for office workstations handling everyday productivity tasks. The module follows JEDEC standards to ensure a warranty-safe upgrade path for these specific platforms.

Sustained 2666MHz Operation

The memory runs at PC4-21300 speed with CL19 latency and 1.2V voltage under continuous workloads. Unbuffered, non-ECC design means it behaves like standard desktop memory during extended multitasking sessions. Backward compatibility with 2133MHz and 2400MHz allows stable operation if the system defaults to a lower frequency.

Tool-Free DIMM Installation

The 288-pin UDIMM slots into the motherboard without extra cables or brackets. Most cases only require opening the chassis side panel and pressing the module until the retention clips click. The main risk is inserting the stick backwards or not seating it fully, which prevents the system from posting.

Questions about this item

How much power does the 8 GB DDR4 2666 MHz CL19 module draw at its rated 1.2 V?

The module runs at the standard DDR4 voltage of 1.2 V, keeping power draw low during continuous all-day operation.

Does my Dell OptiPlex 3080 or 3090 need anything beyond a free 288-pin UDIMM slot to use this memory?

No extra hardware is required; the stick fits any vacant 288-pin DDR4 UDIMM socket in the listed OptiPlex models.

Will this 2666 MHz CL19 kit run stably alongside existing 2133 MHz or 2400 MHz DDR4 modules?

Yes, the module is backward compatible with 2133 MHz and 2400 MHz DDR4 and will down-clock to match the slower sticks.
