It should work, but no guarantee. Sticks will be running at lowest common speed though.
They might be on separate channels. Yes, it's possible to adjust 3000 MHz RAMs to 3200 MHz even if they aren't officially certified for that speed.
Yes, the memory controller operates at a single speed. You can attempt to boost the slower modules, but they may not function properly (such as failing to boot or causing instability).
