" rel="nofollow - I recently upgraded my MB AB250M Pro4 to the latest 4.70 BIOS and it is working fine.

I have a Ryzen 7 1700 CPU

However the settings for overclocking are a bit different than before. I have no issues using

Ryzen Master to get the CPU clock up to 3.6 or higher and the machine is stable.

When I set the BIOS CPU Frequency to 3200 and no voltage change, the machine boots, but

I get partial screens, can't login, black out put on screens. Machine is useless. When I put

it back to default settings, it works fine again. Default on this CPU is 3000 I believe.

I was previously with the 3.x BIOS able to get 3600, so something is wacky. Anybody else

have similar issues? The overclocking in the BIOS is useless at this point.

I assume the BIOS CPU frequency field is MHz, not GHz (like 3.2) It was MHz before. Of course nothing

says, so I can never be sure.
