pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

@pastrychef DRM works with IGPU enabled from BIOS on SMBIOS 19,1 with these boot arguments;

shikigva=32
shiki-id=Mac-7BA5B2D9E42DDD94

But no Netflix on Safari. :cry:

Apple TV+ and Purchase movies work without any problem.

Is Netflix working on Safari with your SMBIOS iMacPro1,1?

Are you streaming from the Apple TV app or are you downloading? Downloaded videos have always played. It's streaming that is the problem.

Netflix not working on Safari tells me that HDCP is still not working right.

With iMacPro1,1, Amazon Prime videos work fine in Safari (I don't have Netflix). Streaming videos also work fine in Apple TV app.

I can add that with iMacPro1,1 (with or without iGPU enabled) Netflix works on Safari and Prime.

Yes, Apple TV+ App streaming works I didn't try downloading.
 
Did you test full shows or just trailers?

I tested full shows. Even, I resumed where I left on "See". It's really great. BTW shiki-id= is not changing your actual board-id number.

I test it with;

Code:
ioreg -lp IOService | grep board-id

And it's using my actual 19,1 SMBIOS board-id.
 
@pastrychef I tried first time the Overclock and I don't get any performance.

I used these settings;

Enhanced Multi-Core Performance Disabled (I tried Enabled also)
CPU Clock Ratio 50
X.M.P Profile 1
CPU Vcore 1.375V

And the Geekbench score is;

Before 36517
After 36815

BTW, how can I be sure, I am working on 5GHz?

Wow. 1.375v is very high... Be careful with such high voltage...

You can try the following guide on overclocking:

No, improvement. Many parameters in the video, don't include in the new BIOS. Geekbench score after following the video; 37015.

Enhanced Multi-Core Performance Disabled (I tried Enabled also)
CPU Clock Ratio 50
X.M.P Profile 1
CPU Vcore 1.280V
Load Line Calibration Turbo
C States Disabled

Ring Ratio and Uncore Ratio are the same things? In new BIOS no Uncore Ratio anymore.

Enable the Enhanced Multi-Core to allow all cores to go to 5GHz.
Uncore Ratio is called something else in the new BIOS... I can't remember the name...
