I'm back at it again on my Taichi X370/1700X system. I also have an ROG Hero VII/2700X system and the down clocking works as advertised on that system.

I just update the BIOS to P5.50
Set the BIOS to the defaults
Made sure everything was set to the standard defaults in OC Tweaker
Went to AMC CMS>Zen Common Options>Custom Pstate/Throttling>Accept>
Changed Pstate0 to Custom and set Pstate0 FID to 98
PState0 settings:
Frequency(mhz) 3800
Voltage(V) 1350000
Pstate0 FID 98
Pstate0 DID 8
Pstate0 VID 20

Pstate1..7 Auto

Went back to OC Tweaker and set the XMP to XMP2.0 Profile 1
Changed CPU Vcore Voltage to Offset Mode
Set the Offset to 0.00625
Changed the CPU and VDDCR_SOC LLC settings to Level 2

System runs at a fixed 3800 and the Vcore goes up and down based on system load. I cannot find the secret setting(s) that will allow this thing to down clock. I think I have tried every combination of Pstate settings and CPU frequencies and nothing changes when it comes to down clocking the CPU.

Help would be appreciated!!]]> Thu, 30 May 2019 21:10:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=8543&PID=63394&title=taichi-x370-bios-4-60-down-clocking#63394 <![CDATA[Taichi X370 Bios 4.60 Down Clocking : I used 3875 @ 135625 Vcore originally...]]> https://forum.asrock.com/forum_posts.asp?TID=8543&PID=50840&title=taichi-x370-bios-4-60-down-clocking#50840 Author: Ken429

I used 3875 @ 135625 Vcore originally under Bios 3.2 because that was the maximum my 1700X would run Handbrake without crashing or having to use excessive voltage and heat to go faster!  Everything worked as advertised, the system down clocked and lowered the Vcore when not under load.

I tried 3825 based on one of the many suggestions above.

I tried 3800 based on the last suggestion and it too had no effect.

Where are the experts that will agree that Bios 4.60 is flawed when installed on a Taichi X370 MB.  Again, does it work correctly on the Taichi X470 MB and a 2700X CPU?

So...since prior to Bios 4.60 everything was working as advertised I have given up chasing smoke and hope that ASRock fixes the down clocking issue (at least for some of us) in Bios version 4.70.  

In the meantime it is a minor issue since the voltage drops when the system is idle and the idle temperature is ~24C.  Don't know what is going on inside the CPU that could cause a problem running at 3875 @ ~.5 Vcore.  I wonder what the 2700X will do on this MB with the 4.60 Bios.


Try using an even number in 100's, rather than 25's.  I'm not sure why you went with those numbers anyway.  So, either use 3800 or 3900 and adjust voltage accordingly.

I had the minmum power setting in the AMD Ryzen Power Plan set to 40%.  That worked several Bios's ago!!  I changed it to 50% as you suggested.

Bottom line the system will not down clock but does drop the voltage when idle.

I wonder what advantage there is down clocking since the system idles at 24C.

Just an aside, it appears I have to go to into ASRock Settings to set the memory to Profile 1?!

Any other suggestion on what I'm missing?

Are you still loading up Ryzen Master?  Cause if so, that's your problem.  It's more than likely overriding your changes you are making in BIOS when you load it, hence why it doesn't move.

Have you tried setting the clock multiplier to 3.825ghz instead of 3.875ghz? I know it isn't ideal, but its the only thing that works for me, and I'm curious if it works for you too. I have the same problem on my Fatal1ty AB350 itx. It won't down clock any other way if I OC it.]]> Mon, 30 Apr 2018 20:36:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=8543&PID=50717&title=taichi-x370-bios-4-60-down-clocking#50717 <![CDATA[Taichi X370 Bios 4.60 Down Clocking : I tried clearing the Bios again,...]]> https://forum.asrock.com/forum_posts.asp?TID=8543&PID=50709&title=taichi-x370-bios-4-60-down-clocking#50709 Author: Ken429

Same as above except:

Pstate4...7Disabled

Neither work ed.  Voltage reduces when Idle but the system does not downclock.  The second set of settings used to work way back on Bios day 1 or 2.  Then somewhere along the way ASrock fixed the Bios so that the standard Advanced OC settings worked.  Now it looks like they've take three steps backword!

The only thing I haven't tried is clearing the Bios and then just setting Pstate0.  Is that what was done on those that have the system working "properly"?


You still have the same problem because you aren't doing it correctly.  

AMD CBS Setting
Voltage Mode = Stable Mode
CPU Core Voltage = Offset  (Value of what it takes to hit 1.35)
CPU LLC = Level 2
SOC Voltage = Auto
SOC LLC = Level 2

Pstate 0 = Custom
Pstate 0 FID = 9b  (play with this to get your desired overclock)
All other pstates at auto.


In Windows after you are done, you need to change the power plans minimum processor state to 25% or 50%.  

Your computer wasn't downclocking properly before either, cause what you had was an all core overclock.

Dont change CPU Multi in Bios higher as P.4.40 if you not will loss a lot of Bandwidth of Memory and Caches (AGESA 1.0.0.1a + has a Bug). Change it in Windows with AMD Master Tool. Then aso downclock works. 

If you still would use P-State, just set P0, P1 and P2 (for me it works) to Custom. And Change only P0.
