32GB DDR4 UDIMM for Dell OptiPlex

This 32GB DDR4 2666MHz CL19 module 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 that need more headroom for multitasking and larger datasets. The unbuffered non-ECC design matches the standard desktop memory architecture used in these models.

Check your OptiPlex model and slot layout

Verify the exact OptiPlex variant — 3080 SFF, 3080 Tower, 3090 SFF, 3090 Tower or XE3 — before ordering because memory-slot count and maximum supported capacity differ between chassis. Confirm the motherboard has a free 288-pin DDR4 UDIMM slot and that the BIOS is current enough to recognise a 32GB 2Rx8 module at 2666MHz. Systems limited to lower densities or speeds will not accept this upgrade.

JEDEC compliance and backward speed support

The module meets JEDEC standard specifications and is ROHS compliant, ensuring a warranty-safe upgrade that follows the original equipment manufacturer profile. It will automatically clock down to 2133MHz or 2400MHz if the platform requires those speeds, so installation remains simple without manual configuration. No heat spreader is included, keeping the profile low for tight small-form-factor chassis.

Questions sur cet article

Does the 32GB DDR4 2666MHz UDIMM arrive as a single stick or a kit, and is any tool or bracket required for installation?

The module is a single 32GB 288-pin UDIMM. No tools or brackets are needed; it installs directly into a standard DDR4 DIMM slot on the compatible Dell OptiPlex systems.

Should I choose the 32GB CL19 module or a lower-capacity alternative for a Dell OptiPlex 3080 SFF?

The 32GB 2Rx8 module maximises the memory capacity per slot on the OptiPlex 3080 SFF. Select a smaller capacity only if your budget requires it or if the board limits total memory below 32GB.

Will the PC4-21300 rating run at 2666MHz on a Dell OptiPlex 3090 Tower, or does it down-clock?

The module is rated for 2666MHz CL19 at 1.2V and is backward compatible with 2133MHz and 2400MHz. On a 3090 Tower it will operate at the highest speed the platform supports, up to 2666MHz.
