Edit updated links to 2701 bios 2701, names in links fixes some bugs and raises settable fmax offset. this is still based on the same AGESA version as 250x so dont expect any difference in Fclockiness against that version.
Hi guys, just a little update about my bios 3003 issues: seems like disabling global c-state fixes system instability for fclk>1600Mhz. My system is now running stable at fclk=f_ram=1800Mhz, without random restarts or whea errors.
Searching around seems like first gen ryzen idle state freezes/restarts was solved modifing the following bios setting: Advanced -> AMD CBS -> Power Supply Idle Control
As far as i know Ryzen2 series should not suffer from this problem, isn't it? Infact my system was rock solid with all bioses relased before 2311.
Some news about Crosshair VIII + Ryzen 3900X + Bios3003 stability. After some researches and experimentation i found that these settings makes my system fully stable without whea error or random resets:
I did it 1900MHz FCLK with 4x8GB 3800MHz cl14 (bios 3001) what i did first ... i did put all the stuck timings and speed (enable docp) for me it like this 14-16-16-36 3800mhz
then i did the voltages dram voltage 1.5 b-die SOC 1.125 vddg ccd 0.980 vddg iod 0.980 clod vddp 0.800
Now dont use 1900 fclk, first you use 1833fclk and then f10 so your motherboard use the voltage we sit After the reboot with the new settings ,enter the bios again and use 1900fclk and f10 again. For me my pc has working without errors or issues for a week.
