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

[pastrychef]

Just updated Mojave + Sapphire Nitro+ Vega 56 without any issues
I use the Vega_Tab kext to undervolt and tweak the Vega settings.
Can I do some more tweaking?
@pastrychef the second monitor only works with WEG, is that normal?

You can tweak as much as you like. Every card will have slightly different limits.

Yes, multi monitor does not work without WhateverGreen for me either.

I would have thought so too, but whenever I try to utilize the shikigva 1 or 57 flags, FCPX/Compressor fails to utilize hardware encoding/decoding for h.264. Using the flags does not lead to a hard crash of FCPX or Compressor, but the export will fail and real time h.264 decoding will be sluggish My EFI is essentially the same as that outlined by @pastrychef, with a SMBIOS of iMac 18,3, and 9900k and spoofed device id for the iGPU. I've kept Lilu and WEG up to date with the latest versions. It's good to hear your system works well, is your setup or EFI linked somewhere, perhaps it'll help me resolve this issue.

As far as I've read, the shikigva still seems to be a valid boot argument for WEG. @jaymonkey's guide still lists the shikigva boot argument in his lilu thread. Agree the github page does not list shikigva as a boot argument. But setting the different values has a definite effect on how FCPX/Compressor works on my system.

Yes. It's integrated with WhateverGreen. Not discontinued.

Hello Pastrychef.
Your manual helped me a lot to make my building.
But my video card RX580 Pulse works with artifacts.
The system High Sierra 13.6 detect it correct. When I select a background with mountains, a flicker appears in the lower left corner of the screen. If I select another background, flicker disappears.
I put it in slot 8x but no change.
And in Windows it works without problems.
Maybe you will have some ideas what to do with this?

Clover is 4871, Lilu + WhateverGreen latest.

I've never seen or heard of this.

Hi,

Someone ever experienced a crash / panic caused by intelmausiEthernet? I had sometimes a crashreport after wake from sleep. I've updated to latest 2.5.0d0 version and it never happened since.

Hi @pastrychef
I just learned that "Adaptive Mode" for CPU Voltage is broken. It will lead to 1.52V being sent to the 9900K (Used OCCT and CPU-Z to get these Numbers in Windows). Scary high! 1.3-1.4 is the safe area. I want to stay at around 1.3 max because of the heat.
This was with the newest BIOS 1802, but maybe this is also true for older versions.

So I had to change to "Manual Mode" and put in my 1.3V. This worked fine but gives me higher temps on the long run, because even if the Turbo is turned off after about 80 seconds of workload and the clocks will fall down to around 3,6 Ghz, the Heat will stay the same (because the voltage stays the same?)

I use:
Sync All Cores
48
LLC5
IA DC Loadline : 0.01
IA AC Loadline : 0.01
SVID: Enabled
SVID: Best Case Scenario


Could you please tell me the CPU-Related BIOS Settings that you use today?

Oh, and also AVX Offset -3

But in your fist post you said: we should not use this with OSX. Is that still true?
Does HWMonitor show a reduced frequency for AVX loads under MAC OS ?
I don't know which program uses it on Mac OS. Is Prime95 v29.4 build 7 with or without AVX?

?????? ... best scenario ???????....
how many fans do you have in your system and what type of high-performance water-cooler do you use? ... you have just an i3 .... I doubt you gave the double or triple for cooling system than the processor ...

@pastrychef Radeon VII hacked to work on Vega 10 drivers! 1802 MHz boost frequency. Is it possible for you to make a VGATabkext? You seem to be the master of fine wine with the Vega's. I tried with the Vega Frontier setting but it has a negative effect.
