DELL Inspiron Vostro 3470 SFF Motherboard YP9G7 H370 LGA1151 SR405 laptop replacement part

Dell YP9G7 SFF Motherboard

The Dell YP9G7 is a genuine OEM replacement motherboard for Inspiron and Vostro 3470 Small Form Factor desktops. It uses the Intel H370 chipset with an LGA1151 socket to support 8th and 9th Gen Intel Core, Pentium, and Celeron processors. This board is intended for repair technicians or owners restoring a compatible Dell system. Buyers needing a different form factor or chipset cannot use this part.

Build Quality and Connectors

The board follows Dell's proprietary SFF layout measuring 10 x 9 x 2 inches and weighing 1.4 lbs, designed to fit exactly into the original chassis mounting points. It provides two DDR4 DIMM slots supporting up to 32GB of memory alongside SATA and M.2 interfaces for storage devices. Integrated graphics output relies on the installed CPU. The fixed port arrangement matches the Dell case I/O shield without modification.

Practical Limits of the H370 Platform

The H370 chipset caps memory at 32GB across two slots and does not allow CPU overclocking. Only 8th and 9th Gen LGA1151 processors are electrically compatible, so newer generation CPUs will not function. The SFF dimensions restrict expansion card height and length, limiting add-in card choices to low-profile models. Systems requiring more than two memory slots or additional PCIe lanes need a different motherboard platform.
