Don't update your BIOS just for new RAM

Probably not.

Unless you’re installing RAM that’s brand-new to the platform (like a new generation of DDR5 on a board that launched with early support), or you’re trying to run speeds way above the CPU’s official spec, a BIOS update won’t help. Most modern motherboards auto-detect standard capacities and speeds just fine.

The only real reason to update is if the RAM doesn’t work at all — system won’t boot, crashes under load, or runs at a weirdly low speed. That’s when you check the motherboard’s QVL (qualified vendor list) and consider a BIOS update. But don’t preemptively flash a new BIOS because you think it’ll give you better performance. It probably won’t, and you risk bricking the board for no reason.

Save the BIOS fiddling for when something actually breaks.
