System-specific DDR3 kit for Dell Optiplex 790

This 8GB kit contains two 4GB unbuffered DIMMs built to match the Optiplex 790 memory specification. It targets owners of that desktop who want a straightforward capacity increase without configuration guesswork.

DDR3 1333 CL9 1.5V 240-pin non-ECC

The modules run at DDR3 1333 (PC3 10600) with CL9 9-9-9 timings at 1.5V. The Optiplex 790 requires non-ECC unbuffered DDR3 at this exact speed and voltage; any other generation, ECC type or voltage will not work in this system.

Two-slot kit leaves two slots open on a four-slot

The Optiplex 790 provides four DIMM sockets with a 32GB maximum. Installing this pair fills two slots and adds 8GB, leaving the remaining two sockets available for future expansion up to the platform limit.
