ASUS B450M-K and 3200G APU?

TheLegendOfMart · 16 Jul 2019 at 08:09

I am dumb and didn't even think about CPU compatibility. My Haswell machine finally bit the dust so I thought I'd get a cheap motherboard and APU. I don't need PCIE 4.0 so the price of X570 wasn't attractive to me.

I know the 3200G is just a die shrink Zen+ and not Zen 2. Is there any chance this 3200G will just plop into B450 without bios update?

It'll need to have the BIOS updated. Unless you're lucky and it already has the updated BIOS on it already.

Balls. Since I bought them together hopefully they had the sense to flash it since they have a free flashing offer on. I didn't get it from ocuk they didn't have the board I wanted.

If not looks like I'll have to buy a cheap CPU...

asus b450m-k is a trash mobo. for the same price, asrock b450m pro4 is a better option.

only two vendors that can flash b450 without boot kit. Gigabyte - they'll flash the board for you or MSI with some model being able to flash off a USB without CPU

Why is it trash, because it doesnt have a lot of features? If you mean Overclocking I don't plan on overclocking a CPU in it so VRM heat doesn't bother me.

I wanted a cheap board... after some reading it also supports PCI-E 4.0 on both GPU and M.2 Slot with a compatible CPU.

it may not currently, but the asus m-k doesn't have any heatsinks on the vrms at all...alarm bells should automatically start ringing as to how cheaply it's made that asus couldn't stick 10p worth of metal on the board.

yes, asus has released their pcie4 support bios for older mobos, hopefully other oems will follow suit.

It will be running an APU, it's hardly going to be stressed...

It wasn't flashed with latest bios, I'll have to buy another CPU now
