Any Skylake System Definitions for Mac Pro 6,1 with Intel Core i7-6700K 4.0GHz?

What do you mean? The MacPro6,1 is not Skylake.

So, I think is all right!

Any reason why I'm not going up to 3900?

When I run, sudo ~/ssdtPRGen.sh,

I see this,
Scope (_PR_) {222 bytes} with ACPI Processor declarations found in DSDT (ACPI 1.0 compliant)

Do I need to change something in the bios to get to 39?
Attached a copy of my bios...

I can't do it. I download it manually but after i got that error (I have i7 6700 and smbios is imac 14.2)

Warning: 'cpu-type' may be set improperly (0x0705 instead of 0x0905)

- Clover users should read https://clover-wiki.zetam.org/Configuration/CPU#cpu_type

[dnetcrawler]

What do you mean? The MacPro6,1 is not Skylake.

Right know I have SMBIOS set up as iMac 17,1 and ran the script. Can the system be setup as MacPro 6,1 and run the script without issues? It's a Intel Core i7-6700K 4.0GHz Skylake.

 

[EDM9313]

I have everything on my build working perfectly except power management I think. Intel power gadget shows that I am stuck at 4.4 ghz (i7 4790k) with just a few dips below. I followed the script to generate the ssdt and I have attached my results from that. It looks better than without the ssdt, but I do not think it is working properly. Any ideas?

I'm trying to run ssdtPRGen.sh for a Sandy Bridge-E processor i7-3960X. It says is support on page one, but I'm getting the following:

I have to go with the others saying they don't see the point. I'm idling at lower clock than when I had my SSDT in clover. Granted, I feel like the idle should be a lot lower (6700k idling at 2.6GHz) but its better than with the SSDT where I was hovering between 4 and 4.5Ghz. I definitely feel like there should be more states below 26 if the low frequency mode is 800 MHz but what do I know...

Can anyone confirm working for Broadwell-E cpus?
