Genuine Dell OEM motherboard for Inspiron 14 3421

This replacement board integrates an Intel Core i3-2375M processor running at 1.50 GHz and discrete Nvidia GT730M graphics. It is built specifically for the Dell Inspiron 14 (3421) models that originally shipped with dedicated graphics. Installers must verify the part number R20C0 against the existing unit before ordering.

FCBGA1023 soldered CPU and fixed GPU layout

The processor and graphics chip are permanently mounted, so no socket swap or graphics upgrade is possible. Connectors follow the original 3421 chassis design, meaning existing cooling assemblies, display cables and I/O ports align without modification. The board arrives as a direct drop-in for the factory systemboard.

Restores discrete-graphics 3421 units to working

This part replaces a failed motherboard in Inspiron 14 3421 laptops that were configured with Nvidia graphics; it will not fit the integrated-graphics variant. The upgrade value applies only when the original board has failed, since the soldered i3-2375M and GT730M offer the same performance as the factory specification.

Questions about this item

What processor socket does the i3-2375M use on this motherboard?

The i3-2375M is soldered in an FCBGA1023 package, so there is no removable socket.

Which laptop chassis does the R20C0 board fit?

It fits the Dell Inspiron 14 (3421) chassis with discrete Nvidia graphics.

How do I install the R20C0 motherboard, and what step is often missed?

Remove the old board, transfer the CPU heatsink and discrete GT730M cooler, then reconnect all ribbon cables; the step often missed is reapplying thermal paste on both the CPU and GPU dies.
