Genuine Dell Latitude 3390 Motherboard

This genuine Dell motherboard is designed specifically for the Latitude 3390 2-in-1 laptop. It arrives new and carries the manufacturer part numbers G1MGM, 0G1MGM and CN-0G1MGM. Repair technicians and IT departments use it to restore system functionality on compatible chassis.

Soldered Core i3-8130U Processor

The board integrates an Intel Core i3-8130U processor running at 2.2 GHz, which is permanently mounted and cannot be upgraded or replaced separately. Buyers must verify that this exact processor matches the original unit; systems requiring a different CPU or a socketed upgrade path cannot use this board.

Integrated Graphics Under Load

Graphics are handled by the on-board Intel HD Graphics engine, which shares system memory installed in the two DDR4 SoDIMM slots. During sustained workloads the integrated GPU relies on the laptop's cooling solution to maintain stable clocks, as no discrete graphics option exists on this platform.
