Compatible upgrade for Dell Optiplex 780

This 4GB kit contains two 2GB DDR3 DIMMs built to run at 1333MHz with CL9 timings. The modules are unbuffered, non-ECC and operate at the standard 1.5V. They are designed specifically for Optiplex 780 DT, MT and SFF desktops.

Verify your desktop form factor and slot count

The kit fits DT, MT and SFF versions of the Optiplex 780 which provide four 240-pin DDR3 slots and support up to 16GB total. Confirm your chassis type matches one of those three and that free slots remain for the two sticks.

Two matched sticks enable dual-channel operation

Installing the pair together lets the memory controller run in dual-channel mode for higher bandwidth. The package includes only the two DIMMs; no heat spreaders, cables or software are supplied.

Questions about this item

Does the 2 x 2 GB kit include anything besides the two 240-pin DDR3 DIMMs?

The package contains only the two memory modules; no extra cables, brackets or tools are supplied.

Should I pick the 1333 MHz CL9 1.5 V version or a different speed for my Dell Optiplex 780?

The Optiplex 780 DT, MT and SFF are specified for DDR3-1333 (PC3-10600) at 1.5 V, so this kit matches the required speed and voltage.

What does the 1333 MHz rating mean once the RAM is installed in the Optiplex 780?

The system will run the memory at 1333 MHz with CL9 timings, giving a peak transfer rate of PC3-10600 across the four DIMM slots.
