ASRock/Other board issue with JAVA games/apps - All/Multi CCD cores not being utilized.

I'm unsure on what may be causing this as mentioned below, It's likely have something to do with the ASRock bios.
The ASRock (OCF) board bios that this issue is happening on is extremely "minimal" compared to an ASUS/Gigabyte board, I'm unsure what could be affecting it like this.

As a demonstration I've attached a video below showcasing a Java Game (Minecraft) Running on Lunar Client and using Adoptium 21
I've tried different Java runtimes including atleast 2 versions of each as well as (Feather Client) & Default MC.

CPUSetSetter for Java works correctly on ASUS motherboards (X870E Apex/Strix), Not sure about other boards/manufacturers.
Every other application/game I've used works fine, As show in attached video I try run every application from CCD1 (freq)

• 9950X3D - X870E Taichi OCF
• Global C-State Control (in BIOS): Enabled
• X3D Gaming/Turbo Mode (in BIOS): Disabled
• CPPC Preferred Cores (in BIOS): Frequency (I have tried all available options)
• Game Mode: Disabled

*note when utilising both ccd's (all) normally, expected fps in the shown scenario is aprox 4.5k-5.5k

Extra info I forgot:

• Option in-game to limit FPS when unfocused. (15)
• All demo videos are identical, this was just a showcase.
• Using Affinity to set the cores have the same affect.
• Still unable to find any indiactors in BIOS to determain why this is being caused.

Not limited to JAVA written games.

From what I'm seeing in the video I'm not seeing any unexpected behaviour, other than the entire Avg CPU column somehow being 0.0%.

This is what I can tell from your video:

• With the Freq mask on javaw.exe, all the heavy CPU usage is on the frequency cores. (Except the load on CPU0, which is Windows doing interrupts and driver tasks). That seems normal.
• With the Cache mask, the load on the frequency cores is heavily reduced and the heavy usage has moved onto two of the cache cores.
• And finally the All mask (which does the same as ) lets Windows completely decide which cores the game can run on. Because your CPPC Preferred Cores is Frequency, Windows will first prefer to use the frequency cores. Only when the frequency cores are (almost) fully used it will start to really make use of the cache cores. And because Minecraft is only using 2-3 threads heavily, there is not enough load to also make the cache cores kick in. So the CPU load will stay on the frequency cores.

Could you clarify the issue a bit more? What's the behaviour that you're expecting to happen exactly? Are you expecting the CPU usage to be both on the frequency and the cache cores at the same time?
