System-Specific DDR3 Upgrade

This 8 GB DDR3 1600 MHz DIMM is built for Dell Optiplex 790 MT, DT and SFF desktops. It installs in a single 240-pin slot and runs at 1.5 V with CL11 timings. The unbuffered, non-ECC module uses a 2Rx8 rank configuration and major-brand chips. Computer Memory Solutions guarantees compatibility with the listed systems.

Ideal for Single-Slot Capacity Increases

Owners who need more memory for everyday workloads and have a free slot will benefit. The 8 GB density suits the platform maximum of 32 GB across four sockets. Buyers who want ECC error correction or registered buffering should look elsewhere. Systems requiring a different DDR generation or pin count cannot use this module.

Ready-to-Install Single Module

The package contains one memory stick with no heat spreader or additional accessories. No software or drivers are required for operation. Product appearance may vary from the reference image. A limited lifetime warranty applies when purchased directly from the manufacturer.

Questions about this item

My Optiplex 790 MT has four DDR3 slots — will this 8 GB stick work alongside the original 4 GB modules already installed?

Yes — the board supports up to 32 GB total across four slots, so adding this 8 GB DDR3 1600 CL11 DIMM to existing modules is supported.

After installing the CM10246412800DIMM, how can I confirm it is running at the rated 1600 MHz CL11?

Open Task Manager’s Performance tab or run CPU-Z; both will show the module operating at 1600 MHz with 11-11-11 timings at 1.5 V.
