CMS 2GB DDR3 module for OptiPlex 780

This 240-pin DIMM delivers 2GB of DDR3 1333MHz memory for Dell OptiPlex 780 DT, MT and SFF desktops. It runs at 1.5V with CL9 latency and unbuffered, non-ECC operation. The single-rank 1Rx8 stick uses major-brand chips and installs directly into any of the four available slots.

Passive thermals and standard DDR3 power

Without a heat spreader, the module relies on case airflow and the low 1.5V DDR3 voltage to stay cool during typical office workloads. Power draw follows the PC3-10600 specification, adding minimal load to the system's existing power budget. Silent operation is assured because no active cooling is present.

Adds capacity to a 16GB ceiling

Each slot accepts up to 4GB, so this 2GB stick helps move a configuration toward the 16GB maximum supported by the platform. The upgrade is worthwhile when the current total is below 8GB and multitasking feels constrained. Buyers needing more than 16GB total or registered ECC modules should look elsewhere.

Questions about this item

How do I install the 240-pin DDR3 module in my OptiPlex 780 and what step is often missed?

Power off and unplug the desktop, open the case, align the notch on the 240-pin DDR3 stick with the slot key, press firmly until both side clips click shut, then verify 1333 MHz operation in BIOS — the step most people skip is confirming the speed after boot.

What maintenance or replacement will this 2 GB DDR3 1333 MHz stick need over time?

No routine maintenance is required; keep interior dust-free and ensure the 1.5 V supply remains stable — replacement is only necessary if you expand beyond the four-slot 16 GB maximum or a module fails.

What limit appears first when this CL9 1.5 V unbuffered DIMM runs sustained workloads?

The 2 GB capacity ceiling is reached before thermal or voltage limits, causing swapping on memory-heavy tasks; the module runs at standard 1.5 V with no heat spreader, so temperature stays within DDR3 norms.
