16GB DDR4 SODIMM for Dell OptiPlex AIO

This 16GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is built specifically for Dell OptiPlex 7480, 7490 and 7780 all-in-one systems. The non-ECC, unbuffered design matches the factory memory specification for these models.

260-pin form factor with no heat spreader

The standard SODIMM connector fits directly into the memory slots on the supported OptiPlex AIO boards. A low-profile design without a heat spreader helps clearance inside the compact chassis. JEDEC and RoHS compliance ensures the module meets the original equipment electrical and environmental requirements.

Verify your exact OptiPlex model before ordering

This upgrade only supports the three listed all-in-one variants; other OptiPlex desktops or laptops are not covered. Confirm the system currently uses DDR4 SODIMM slots and that the maximum supported capacity per slot allows a 16GB module. Buyers needing ECC, registered memory or a different pin count should look elsewhere.

Questions about this item

What DDR4 standard and speed does this PC4-25600 CL22 SODIMM run at?

It operates at the JEDEC DDR4 3200 PC4-25600 standard with CAS latency 22, so the memory controller will cap at 3200 MT/s.

What physical slot and notch does the 260-pin SODIMM need?

It fits a standard DDR4 260-pin SO-DIMM socket; the key notch matches the Dell OptiPlex 7480, 7490 and 7780 AIO motherboards.

How is the module installed and which step do people often miss?

Power off, open the chassis, align the notch with the slot key, insert the SODIMM at an angle, then press down firmly until both side clips click into the notches.
