Genuine Dell AIO Motherboard

This new Dell motherboard is built for the Inspiron 22 3280 All-in-One desktop and includes a soldered Intel Core i3-8145U processor. It matches the original factory specifications for power delivery and thermal design. The board supports dual-channel DDR4 SODIMM memory and provides both M.2 and SATA storage connections. Integrated UHD Graphics 620 handles everyday display output.

Who This Fits

Repair technicians and system builders who need a direct replacement for a failed Inspiron 22 3280 board will find full mechanical and electrical compatibility. Buyers who want a socketed processor for future upgrades should look elsewhere because the CPU is permanently attached. Anyone building a custom chassis must verify that the 9.5 x 9.5 x 1.5 inch form factor and mounting points match their enclosure.

Deciding Specification

The soldered Intel Core i3-8145U with a 3.90 GHz maximum turbo frequency is the fixed performance ceiling of this motherboard. Since the processor cannot be swapped, the board is only suitable for workloads that this dual-core four-thread chip can handle. Confirm that your memory, storage and operating system requirements align with this level of performance before purchase.

Questions about this item

What does the i3-8145U's 3.90GHz turbo mean for everyday workloads on this board?

The processor reaches 3.90GHz under short bursts, so office apps, web browsing and light multitasking stay responsive while the AIO's cooling keeps sustained speeds lower.

How does the M.2 and SATA support limit storage choices?

The board accepts one M.2 drive and one 2.5-inch SATA drive, so you can pair a fast boot drive with a larger data drive but cannot add a second M.2 device.

Will the 9.5 x 9.5 x 1.5 inch board fit my Inspiron 22 3280 chassis?

Yes, those are the exact factory dimensions for the 3280 AIO motherboard tray, and the 1.3 lb weight matches the original mounting points and screw pattern.
