Dell G15 5511 replacement motherboard with i7-11800H

This genuine Dell OEM system board is built specifically for the G Series G15 5511 laptop. It arrives with an on-board Intel Core i7-11800H octa-core processor and discrete Nvidia RTX 3050 graphics. The part restores original performance for owners of that exact model.

Integrated i7-11800H and RTX 3050 change repair

Because the CPU and GPU are soldered directly to the board, the replacement delivers the full 8 cores, 24 MB cache and up to 4.6 GHz boost alongside 4 GB GDDR6 video memory in a single step. No separate processor installation or thermal paste application is required. The discrete graphics are reinstated without additional parts.

OEM board matches factory mounting and connectors

The board uses the Dell JHTH3 part number and aligns with the original chassis screw points, display cable, keyboard ribbon and power jack. Port layout, Wi-Fi module slot and battery connector remain identical to the factory unit. Swapping the board restores all I/O without adapter cables or case modifications. || Builders needing a different GPU tier or a socketed CPU cannot use this board.
