By the way, what were you working on with your motherboard? Mobo boards are quite challenging to work with these days. I'm curious—did you manage it, and if so, how did you accomplish it?
Without a CPU it won't perform well, it can't even try to POST without the processing power. The only option is to update the BIOS if your board supports it, otherwise nothing more.
It was a bit tricky to find the correct place I think I adjusted it using the standoffs while installing.
