In my setup I can relate to these options:
OC tweaker: Overclock mode (speed bus) (option auto/manual) manual: bclk(mhz) cpu frequency and voltage (vid) change soc/uncore oc mode (options: auto disbaled enabled soc/uncore oc voltage (VID) (auto) cld0 cddp voltage control cld0 cddg ccd voltage control DRAM etc below ############### Advanced/amd cbs: performance custom core pstates accept Options auto/custom) custom give: pstates freq mhz pstates vid I went through alle menus under both main sections - didn't see the power supply idle settings. I also searched the nvram.txt for possible combinations. Could you check the codeshare is posted if 'I need better glases' ? :D Already much appreciated for your help sofar! |

On ASRock boards, after updating the BIOS, going to: OC Tweaker > OC Mode , setting it to AMD CBS, and then going to Advanced > AMD CBS > Power Supply Idle Control, and setting it to typical current idle. Press F10, and then Enter to cement it. The UI might be confusing otherwise.

I managed to get nvram.txt from winsce - Anybody which settings I need to change ? There are some obvious ones with Cstates but just like to fully unlock and have c3+ states.

no worries!
advanced/cpu configuration/pss support was already on enabled the article also mentioned disabling advanced/cpu configuration/smt disabled made not difference (still on pkg(os) c3 max) all the other mentioned in the reddit post might be already inapplicable of it's version. At least I couldn't find them in my p3.40 |

HI ! Thanks for replying and helping to solve the c-states issue!
I've been searching in the bios for the two setttings: Cool Quiet: enabled Power Supply Idle Control: Typical I didn't see them. I've checked advanced/cpu configuration and also went through all the overclocking items. Did I miss them or is it like some b450m forum messages I found that asrock removed these? Would you know where the two settingss are located in the p3.40 version for b550m ? Most likely I missed them... |

I'm trying to to achieve lower power consumption on 'idle' for my server.
It idles around 18-19 watts having nothing attached. Running RKE2/K8S around 21-22. I've noticed in powertop it only offers c3 state and not like my other machines upto c10. Asrock riptide B550M P1.40 Ryzen 7 pro 4750G gskill 64 gb I've found AMISCE (SCELNX or SCEWIN) to be able to unlock bios and enable the hidden feature for an intel based motherboard. As discribed here: https://askubuntu.com/questions/1483343/c-states-not-fuctioning-on-ubuntu-server-22-04-please-help#:~:text=So%20you%20have%20to%20enable/change%20hidden%20BIOS%20menus%20by%20using%20AMISCE%20(AMI%20Setup%20Control%20Environment)%20utility%20v5.03%20or%205.05%20for%20Windows%20(it%20can%20easily%20be%20found%20on%20the%20internet).%20So%20you%20have%20to%20install%20Windows%20and%20to%20enable%20Administrator%20password%20in%20your%20BIOS Amisce (scelnx) errors: AMISCE not supported on this system So has anybody else solved this problem not having higher c-states for an amd/am4 motherboard ? I'm happy to wreck the motherboard attempting to achieve this. |
