Z690 Chipset Motherboards and Alder Lake CPU

I think I know what it is. You need equal number of P and E cores. Doesn't work on uneven P and E cores processors.
I bet, if you make equal number of P and E cores in bios and use the according with the processors number the SSDT-PLUG-ALT.aml, it will work.

Yes, this is exactly what I was thinking. Will try disabling two 2 cores.

Yes, this is exactly what I was thinking. Will try disabling two 2 cores.

Whether we disable two P-cores or two E-cores, the result is Should have 8 cores, but only 4 found.

It makes sense to disable two P-cores so that:

• Active P-Cores = 4
• Active H-Threads = 4
• Active E-Cores = 4

On the i9-12900K, we have this symmetry by default:

• P-Cores = 8
• H-Threads = 8
• E-Cores = 8

Disable 2 P cores. Enable HT and use this.

Bingo...I can confirm that this SSDT is working with all cores and HT is enabled. all you have to do is just enable providecurrentcpuinfo thats it. further testing is required...

Sir, if you allow me please to ask an off subject question, If I flash the Titan Ridge would I be able to use it on my hackintosh motherboard that has no thunderbolt header? my motherboard is Gigabyte UD5H Z77x..Thank you very much.

With 12700K? Please elaborate!
This is amazing

** CONFIRMED **

It is absolutely necessary to enable kernel quirk ProvideCurrentCpuInfo. Summary for i5-12600K:

• Hyper Threading enabled
• P-Cores = 4 enabled
• E-Cores = 4 enabled
• SSDT-PLUG-ALT.aml with Processors 0 to 7 (8 total) defined

You have 8P and 4E. You need to disable 4P in bios and use attached. You lose some power in hack and gain some power in windows or another OS. You have not the best processor for this situation (for now).

NO need to disable any P-Cores

Have you checked benchmark?

I have not yet assembled the build. I can return it and get a 12900K instead, If we fear the core count equality requirement will persist, I will add the extra $

 

[MatiCohen]

Yes with all core enabled

Can you share benchmarks?
