AMD High Sierra Kernel Release and Testing

Normaly OpenCL is way faster in Mac OS X, because its optimized. But other side, the OpenCL Driver for AMD in Mac OS X is buggy. (Blender Szene Fishy_Cat will be rendered without showing hairs) In Geekbench the CPU Test in MultiCore is almost as twice as good as in Windows. Mac OS X is performing much better there. I have the Water-cooled edition of the Frontier, I don't believe that it is a Fan Issue, its a general Issue. (Look on the GPU Meter on the Card, getting to 80% every few seconds. Thats the reason why Fan getting faster)

The drivers for the vega are a bit premature, last year we had similar problem witht the RX 480 or Polaris 10 Cards. But, it only took a couple of beta updates to fix it, this is an issue that has drawn on for some time with Vega. I wonder if apples use of vega in the iMac Pro has a fan or if it’s a system fan or two for the whole computer? It may explain it but they also know that older MacPro users are switching to these cards. I hope they adjust the drivers soon, they are much better than the originals in the first betas of HS.

I guess Apple is using Heatpipes for the Vega in the iMac Pro and is cooling the whole System with the 2 Fans. (including CPU...)

I really think about buying a real iMac Pro (smallest Version). Its just a Masterpiece. Performance is really good and Cooling-System is good and quiet. (I never suspect that)

This would make sense I suspected this for some time but haven't checked into the iMac Pro specs.    We have 9 Vega IDs in the AMD10000Controllerkext but we only have 3 models available to date.   6 more Vegas or variants to find.

I've installed macOS 10.13.2 on my Ryzen 1700 with Asus B350F motherboard. Thanks to all the core contributors to this forum. I'm unable to load Nvidia Web Drivers for my MSI Lightning X 1080Ti. Can you help me?

Your able too boot up? What’s the issue? Have you tried to install web drivers?

Tried this does not work.

Thanks for answering.  The only thing that works is to use 12.6 kexts.

 

This is weird for this card, it used to be one of the only AMD cards to work in El Capitan and Sierra without a helper card or IGPU.    Now it doesnt work anymore.

Still doesn't install for me

Did you try boot arg. nv_disable=1

Did you try boot arg. nv_disable=1

I did, thanks for the reply! Fixed it by redoing the disk setup process.

 

Right now at post install, done the post command from the usb, facing boot problems.

 

 

Early boot complete. Continuing system boot.

And then it poofs a crapload of lines and reboots. Can't seem to get past that phase. Gonna try re-running the post command again. [EDIT, doesn't work]

 

Reinstalling the entire again.. 

 

Different issue came out.

MAC address? wew..

I followed the pre and post commands and the exact procedures as stated. Nothing wrong there, furthermore I reinstalled and redid the entire procedure twice already. 

 

Nevermind, reinstalled with AMDHS, way easier and it works

Hmm, maybe its just the Nvidia WebDriver? The Webdriver is full of bugs and in many cases bad performance. (Additional to this the AMD Kernel is destroying much performance, with Nvidia GFX more than with AMD GFX)

 

I've been poking around and it may be we are getting a default PCI slot support for i386/32 bit.    I noticed this the other day in IOReg it read PCI0@2 i386.   This would explain the lower performance especially for Nvidia cards as they have announced that they will be dropping 32 bit support for future drivers.    

 

It's just a hunch so far but it may have to do with the unsupported CPU status and "not serialized" status of the PCIE slots.    See the pic and the DSDT compile error message 64 assigned but 32 bit enabled.

A little further digging resulted in this.   Check out the IopCIFamilyKext and i386 support for PCI@2PCI the 0x80604? 0x0fffffffff assignment.    Then check out the IOReg IOPower @ IOPP or GFX0 the same set of default numbers.    This may be the cause of the issue if we can assign new defaults to get 64 bit support maybe we can fix our graphics support to Intel levels in OSX?

 

Please try this with an Nvidia card using DPCIManager and IOReg.    Lets see if we can duplicate this.

Interesting....
