Can i flash bios on a b450 motherboard while a 3000 Ryzen CPU is installed or do i have to flash it before i install the CPU ? does it matter?

No. The board has to be made compatible with the CPU before the CPU will work. I think there are a few boards out there that have a way to update BIOS without a CPU installed, but I doubt any of those would be B450.

Aerocool DS are the best fans you've never tried.

The B450 Tomahawk? Huh. I thought that feature was limited to high-end boards for some reason. Good to know...

A lot of MSI b450 baords have that feature, even low end ones like the A pro or the gaming plus.

Outside of MSI there are only 5 other board who have a bios flashback and none are b450

Depends on the motherboard you have. Only some have that feature, for most you need a ryzen 1000 or 2000 cpu first

I was thinking about the MSI b450 pro and 3800x or 3900x
the thing is I'm coming from Intel and plan to put everything at once(from what i have seen the pro has flash)

the more ironic thing is that MSI only has 1 board with BIOS flashback on X470, that's the M7. No idea why they did it.

No, Probably not. Have a look at the AMD boot kit, its an athlon CPU they lend you for a few days so you can update your bios.

No doubt something they were working on while tirelessly making sure their first-gen Ryzen boards would have the best RAM compatibility in the business.

Flashback button will not work with CPU installed. Leave the CPU and RAM out with nothing else connected. Just plug in the CPU power and 24 pin.
