Radeon Compatibility Guide - ATI/AMD Graphics Cards

Yes, I'm also anxiously awaiting 10.13.4.

I don't think I want to bother going through the method in that thread. My system is running so well without a DSDT, I don't want to mess with it. I'm confident that 10.13.4 will get it all right.

Do you have IGPU enabled? I tried launching FCPX, and the system reboots almost immediately. The issue disappeared when I set IGPU to "auto" in BIOS, which basically removed it from OSX entirely. Incidentally, after doing this, the Vega GPU shows "Metal: Supported" in System Report, whereas before it was marked as GPUFamily1 v3.

Has anyone had an issue like this with a Vega FE?

A restart of Photoshop fixes it...but kind of annoying.

I'm anxiously awaiting 10.13.4 too. I do wish they would hurry along with it!

If the 10.13.4 Beta 5 is anything to go by, the Fans have not been fixed (tested on WX9100 + Vega 56 (Reference).

I hope it does, but since the Fan is running high in 10.13.2, 10.13.3, 10.13.4 (beta 5) - I think we might have to look for 10.13.5 and beyond. Also when the fan blows down (it does this if you work with "some" H.264 video, and some websites), it also clocks the card down considerably (a 195.000 score in geekbench can drop to as much as 155.000 when the fan goes "silent").

@jirshaidat What card do you have, since it's silent all the time? Can you share Geekbench OpenCL / Metal scores with us?

I can confirm that my Gigabyte RX 580 Gaming 8gb works OOB with High Sierra 10.13.4 public beta 5

The card is the Asus ROG Strix. Benchmarks attached. It's Worth noting that the fans were on idle (no movement at all) throughout those tests.

Thanks for sharing this! Looks about right for Vega 56 (and a little above as i guess it’s clocked a bit higher then reference).

Putting a 64 vega bios on a reference vega 56 will net you between 190.000-205.000 on each score, not sure if it works with Asus Strix?

Sounds intriguing. Any risks?

If the card has dual bios, should be ok?just make sure to test temperatures (VRM etc). I’m sure the core is fine, but not sure if all components will be cooled down under heavy load.

Just tested 10.13.4 beta 5 - and Vega 56 flashed for 64:
199.xxx in OpenCL and 207.xxx in OpenGL.

Not sure how much this translates in apps like Final Cut Pro X.

Prior to trying to flash your Vega 56 with Vega 64 firmware, make sure that your Vega 56 has Samsung HBM2. If you have Hynix HBM2, you will brick your card.

@jirshaidat Use GPU-Z in Windows to see the HBM2 vendor. This is all new to me, and my card is fine so i guess i was lucky!
