Ryzen 9 and B450

[Brok3nBob]

I have been looking around for a straight answer on this and have have seen conflicting information.

so what I am wanting to know is can you run the beefy ryzen 3900/3950 on a B450 motherboard?

my system spec of current: 

 

ryzen 2 2500x

aurous b450m mobo (bios updated to latest version so know can support ryzen3, but to what end?)

32gb corsair vengance 2400mhz

aurous nvidia gtx 1050 TI 

240 gb kingston SSD

480 gb Kingston SSD

1tb toshiba 5400rpm

Generally yes but probably not that great on that mobo, for what i know gigabyte b450s have weak vrms

Gamers Nexus had a good video on which boards to reuse for Ryzen 3rd gen. In it they only suggest a few motherboards to reuse for Ryzen 9, your's is not on the list. The motherboard's VRM is going to be the main limitation going to a 12 and possibly a 16 core, you are most likely going to need a new board to keep that powered.

Bios updates are horrible at the moment ive been bug testing for 2 days and i still cant get it to boot @Brok3nBob

thanks for the input guys currently running an f40 version of the bios on the mobo generally works ok with current cpu, so what wouly be the max amount of cores you would go for?

You most likely could, there was someone who tried a 12 core on the cheapest B350 he could find and it ran with no issues... now would it last long? Probably not.

But the thing is, if you don't overclock and you actually have a decent B450, as long as you have enough airflow you will be fine.

You could, but I personally would not recommend it.

The Gigabyte Aorus B450 M Looks like a 11-phase VRM, but in reality, it is just a 4(x2) + 3 setup -- not a true 8 + 3.

 

I would recommend that you consider a different motherboard, if you are going for a $500+ USD Processor, especially if you have ANY plans to overclock those 12 cores.
