Hello, I updated my Asrock AB350M to 4.6 BIOS (3.0 before) and my system slowed down considerably. Sometimes RyzenMaster or CPU-Z see the base clocks, and they do not see those made in the BIOS. This is progress ??? Is there anything I should change? Is this BIOS broken? W.T.F

Updated BIOS to 4.60 -> on default settings voltage is way off and temps which are usually 33-35c are now 60-70c but I haven't left it running very long at 1.392-1.42V - tried turning core boost off so I don't know what's wrong. It also says 3.19 in windows setting

Manually overclocking it back to default 1.23v and it won't save either.

Is there a config I can fix this? concerned about damaging ryzen otherwise I'll revert back to 3.30

updating bios is no joke lol will straight up fry your components

I found also a bug in 4.50.

In CPUZ and BIOS my Ryzen is 3.6Ghz but in windows and cinebench its only 3.19ghz.

Which is correct?

I dont want to revert 3.20 because i can now run my ram to 2800mhz

Flashed 4.60 
Still no memory overclocking in OC Tweaker like it was in 3.30 for non XMP memory stick :(

Reverted back to 3.30]]> Sat, 27 Jan 2018 15:21:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=7247&PID=44022&title=ab350-pro4-bios-4-40-oc-mode-change-switch#44022 <![CDATA[AB350 PRO4 - BIOS 4.40 OC Mode Change Switch : ZTR wrote:Did anyone try the...]]> https://forum.asrock.com/forum_posts.asp?TID=7247&PID=44015&title=ab350-pro4-bios-4-40-oc-mode-change-switch#44015 Author: php42

i tried it. asrock OC mode is fixed now.
DRAM voltage still locked to 1.35v. anything over 1.35 won't save.
they seem to have added an option to adjust SoC voltage on the ab350 pro 4, hidden in the AMD CBS settings somewhere. it takes a VID instead of an absolute voltage (similar to pstates). there is no way to tell what this translates to in volts so i didn't touch it. default value is 0 so who knows.

i reverted back to P3.30.
once they fix DRAM voltage it'll be a solid upgrade. stability is otherwise hugely improved (for me 4ghz will now boot into windows, previously 3.9 wouldn't even post).

I've set it over to AMD CBS for now. The RAM timings and voltage still appear to be correct, but with 2400mhz I don't think XMP settings really factor into my build's particular set of RAM. The "XMP" profile has always been the same as stock timings.

Thanks much for the info.

Thanks!

use AMD CBS. asrock mode is super buggy in the new bios so the only way to get reliable results is with a pstate overclock in AMD CBS mode. note that this means you can't use XMP profiles and will need to set your ram timings manually unless you want to run stock ram.

this update seemed to provide a HUGE stability improvement, but at the cost of a whole new swath of bugs in the BIOS. DRAM voltage seems to reset to 1.35v at boot. this is fine for me since it suddenly seems to be stable at that voltage but YMMV.

EDIT: just noticed you were running stock, in that case it probably doesn't matter as auto settings should be the same in either mode.

Can someone tell me what is the max voltage I should go for when OC'ing my ryzen 3 1200? I heard something like v1.42 is the max safe voltage. Or can it go a bit higher without damaging the CPU and decreasing it's life span? Thank you :)

Every chip is different, but as a general rule, it's best to try and keep the voltage as low as possible and still maintain stability, so there's no recommendation that will work in all cases.

Personally, I undervolted my Ryzen 5 1600 deliberately to keep temps in check and was able to get a stable OC (tested) to 3.7GHz at only 1.28 Volts. 

IN my case, I started with the clock speed I wanted (not pushing the chip too hard) and then backed the voltage down from the 1.35 Volt default until I hit the lowest stable voltage I could reliably achieve at that speed.
