Questions about this item

Which processor socket must my existing CPU match for the WMJ54 board?

The board uses an LGA1155 socket, so the CPU you already own must be an LGA1155 part.

Will the WMJ54 fit in the chassis I currently use for my OptiPlex 3020 SFF?

Yes, the WMJ54 is built for the OptiPlex 3020 SFF form factor and mounts directly in that chassis.

What should I check first after installing the WMJ54 to confirm it is working?

Power on the system and verify that the POST screen appears and the BIOS recognises the installed CPU and memory.
