OWC 4GB DDR4 module for Dell OptiPlex 7040

This 4GB DDR4 2133MHz CL15 UDIMM is built for Dell OptiPlex 7040 SFF and Tower systems. It runs at 1.2V without ECC or a heat spreader. The single-rank 1Rx8 design meets JEDEC and RoHS standards for a warranty-safe upgrade.

Replacing slower or smaller DDR4 DIMMs

Swapping an existing 2133MHz stick for this module adds capacity while keeping the same speed and latency. The jump is worth it when your OptiPlex 7040 has a free 288-pin slot and the BIOS recognises non-ECC unbuffered memory at PC4-17000.

Check slot count and maximum memory first

Verify how many 288-pin UDIMM slots your 7040 SFF or Tower board provides and what total capacity it supports. This module is not for systems that require ECC, registered DIMMs, or a different DDR generation.

Spurningar um þessa vöru

Will the 288-pin DDR4 UDIMM fit inside the Dell OptiPlex 7040 SFF chassis?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor that matches the memory slots in both the 7040 SFF and 7040 Tower systems.

What is the correct way to seat the module so the retention clips lock?

Align the notch on the gold edge with the key in the slot, press straight down with even pressure until both side clips snap into place automatically.

When should this 4GB DDR4 2133MHz CL15 stick be replaced or upgraded?

Replace it if memory diagnostics report errors, or upgrade when your workload regularly exceeds the installed capacity and the system starts paging to disk.
