OWC 2GB DDR3 1333 for Dell OptiPlex 790

This OWC module adds 2GB of DDR3 1333 memory to compatible Dell OptiPlex 790 desktops. It is a single 240-pin UDIMM rated at PC3-10600 with CL9 latency and 1.5V operation. The non-ECC unbuffered design targets standard desktop workloads. Condition is new.

Fits four OptiPlex 790 form factors without extra

The stick works in the Desktop, SFF, Tower and USFF versions of the OptiPlex 790. It plugs directly into an available DDR3 DIMM slot on the motherboard. No heat spreader is fitted, so it clears standard retention clips. JEDEC and RoHS compliance keeps the upgrade warranty-safe.

Suits owners wanting a modest capacity bump

Buyers who need higher density per slot or ECC error correction should look elsewhere. Systems already at the board's maximum module count cannot accept another stick. The 2GB capacity limits benefit for memory-heavy multitasking.
