Genuine Dell Latitude 7490 Motherboard with i3-7130U

This new OEM motherboard carries part number 43Y54 and fits the Latitude 7490 series. It arrives with an Intel Core i3-7130U processor soldered in place, running at 2.70 GHz with two cores and four threads. The board measures 11.5 x 7.5 x 0.5 inches and weighs 0.45 lbs, matching the original chassis layout exactly.

Suits owners fixing a failed board

Buyers who need a newer processor generation, more than two cores, or a socketed CPU upgrade path cannot use this part because the i3-7130U is permanently attached. Systems requiring discrete graphics or a different chipset should look elsewhere, as this board relies on integrated Intel HD 620 graphics and the Intel Q270 chipset.

Soldered i3-7130U decides compatibility

The processor is not removable, so the motherboard only works as a direct like-for-like replacement for a Latitude 7490 that originally shipped with this same CPU. Dual DDR4 slots support up to 32GB of memory, while storage options include M.2 NVMe or SATA plus a 2.5 inch SATA III bay. Connectivity covers USB 3.0, HDMI, audio and power through pre-mapped mounting points.

Questions about this item

Which Dell Latitude 7490 motherboard version fits my laptop?

Part number 43Y54 is the specific board built for the Latitude 7490 series and comes with the i3-7130U processor already soldered in place.

What does the 2.70 GHz i3-7130U actually deliver in daily use?

The dual-core, four-thread CPU runs at a steady 2.70 GHz with 3 MB cache, giving enough speed for office apps, web browsing and HD video playback.

What storage interfaces does the board support and what do they limit?

It provides one M.2 slot that accepts NVMe or SATA drives plus a 2.5-inch SATA III bay, so the SATA III link caps sequential throughput at the SATA III ceiling.
