Compatible DDR4 upgrade for OptiPlex 7040

This 8 GB DDR4 module runs at 2133 MHz with CL15 timing and 1.2 V operation. It is built specifically for Dell OptiPlex 7040 SFF and Tower desktops. The non-ECC unbuffered design matches the factory memory architecture of those systems.

288-pin UDIMM form factor fits standard desktop

The 288-pin unbuffered DIMM inserts directly into the motherboard without adapters. No heat spreader is fitted, so clearance inside the small-form-factor chassis remains unaffected. JEDEC and RoHS compliance ensure the module meets the original electrical and environmental specifications.

Limited lifetime warranty with advance replacement

OWC backs the module with a limited lifetime warranty that includes an advanced replacement programme and free technical support. The warranty-safe design means the upgrade does not void the system manufacturer's coverage. No additional software or cables are included in the package.
