tomahawk max MSI B450 Tomahawk MAX [BIOS Question]

[Waqas409]

Right now my bios is 1 step lower from where they support the 5000 CPUs.

What if right now i upgrade my Bios to the latest, will my current CPU which is ryzen 5 3600 works or after the latest bios i need a 5xxx CPU?

Please confirm.

Thanks 

PS: i have read somewhere that if i do the latest bios, i will not be able to used the 3xxx gen ryzen CPUs eg: ryzen 5 3600

I think you are talking about certain CPUs no longer being supported when upgrading BIOS to support 5000 series CPUs due to the EEPROM limitation. This only impacted motherboard using 16MB or 128Mb BIOS chips. 

 

Your motherboard is not affected by this limitation and a BIOS upgrade will be fine (Due to it using a 32MB chip).

It will work just fine. Tomahawk Max does not loose CPU support with Bios updates. And even if it did, like some other boards with small EEPROM, it would loose only the support for the oldest/weakest models like the Athlon GE or the non-Ryzen AM4 CPU-s.
