Dell DDR3 1GB Laptop Memory

This module is a 1GB DDR3 stick rated at 1066MHz with a PC3-8500U specification. It uses a non-ECC design with gold contacts and carries the Dell part number F680F. The unit is a working pull removed from a tested system and verified to function correctly. It targets users maintaining or repairing specific legacy Dell desktops.

Upgrade for OptiPlex 780 and XPS 430

The memory directly replaces or adds to the original equipment in OptiPlex 780 DT, MDT and SFF chassis as well as the XPS Desktop 430. The jump is worth it when those machines currently run with less than the maximum supported capacity or when a failed module must be swapped for a verified working unit. No other platforms are confirmed by the supplier data.

Verify DDR3 slot and model number

Before ordering, confirm the target computer is one of the listed OptiPlex 780 variants or the XPS 430 and that it accepts DDR3 non-ECC SO-DIMM modules. Check the existing memory configuration to ensure a 1GB addition matches the system's slot population rules. The part number F680F should match the label on the module being replaced.

商品問答

Will this DDR3 module fit the SO-DIMM slot in an OptiPlex 780 SFF?

The OptiPlex 780 SFF uses full-size DIMM slots, while this module is a laptop SO-DIMM with gold leads; it will not fit that chassis.

What is the correct way to seat this F680F stick, and which step do people skip?

Align the notch on the module with the key in the SO-DIMM slot, press firmly at a 30-degree angle until the gold leads disappear, then press down until both side clips click; the step often skipped is verifying both clips have fully engaged.

How do I know when this 1066MHz module should be replaced?

Replace the module if the system fails memory diagnostics, shows repeated blue-screen errors tied to memory addresses, or cannot maintain stability at the rated 1066MHz speed.
