AMD Radeon Navi GPU

[trs96]

The Maxsun cards we encountered in the Designare Z390 thread contain unrecognized device IDs. The cards were therefore incompatible with macOS.

It makes more sense to buy a genuine RX 570 with 2048 SP rather than a Maxsun card (they label as a 580) that costs much more and doesn't work in a hackintosh.

I have a Radeon 5700xt Sapphire Pulse. It never crashes and works great all the time. No problems at all that I can think of. I do video streaming, a little Final Cut, Photoshop, Compressor, and some others.

I get random black screen crashes... But this happens also on Windows sometimes. I think it's because I have a 144HZ display connected over display port.

I read that a lot of you have issues/bugs with your RX5700XT. I was planning to get one to upgrade to Catalina. Would you guys recommend to get a different GPU for a 24/7 uptime? It's really important to me that the system doesn't crash/freeze.

@Thireus,

AMD Vega 56 or 64 are also a great choice for a Hack and you can pick them up heavy discounted at the moment as they have been effectively superseded by the 5700 and 5700 XT. I have a Sapphire Vega 64 Liquid Cooled edition in my main rig and it's been super stable for the last four years or so. Have never encountered any GPU related issues with it ever.

Way more compute power than RX 580 and a good one will match or even beat 5700 XT in 32bit FP compute performance.

Sapphire is Apples preferred add-on GPU brand and tend give less problems then some of the OEM cards, if in doubt search the forums before committing. The only negative is that the Vega GPU's have a High TDP and draw a more current than more recent cards but as long as you have a good PSU you should be fine.

Cheers
Jay

So they've been busy. I had an issue since Catalina where my resolution would default to 1024 on my 4K LG. That's been fixed in 11.1 beta. No doubt AMD adding fixes as they continue to work on the Navi chips.

That's it. My system is now pretty flawless. Happy till I get an ARM-based Mac

Thank you for a great help.. as usually ... Appreciated also as usually

Hi there
Can someone kindly share best stable Device properties for RX5700 tx Shappire Nitro+.
Stable but powerful in Opencl and Metal
I found few but they are all adopted from other cards.
I bricked one already (messing to much) so looking for same already tested and working one.
Full config will be appreciated if possible...

Mate you can't generalize overclocking like that. Every silicon device has its own flaws & imperfections and therefore needs its own configuration. If you want stability, go for stock settings. If you absolutely want OC, boot up windows and tweak your settings there where tooling is much better. You can then copy the generated power play tables into OSX.

There is also a Sapphire brand 2048sp, it was a stumper, until we saw the specs on the box, so a good rule of thumb is to stay away from any 580 2048sp models.

Thank you for your answers @jaymonkey, @Gigamaxx, @Hackintoshron,

I decided to buy a Sapphire NITRO+ RX 5700 XT which I received today.

Everything went pretty smoothly. Here is what I did:

1. Replaced my old Titan X Maxwell with the NITRO+ RX 5700 XT
2. Opencore 0.6.3 with boot flag agdpmod=pikera using iMacPro1,1
3. Fresh install of Catalina 10.15.7 - Butter smooth
4. Migrated my data from High Sierra at the end of the install
5. So far so good. Dual display 120hz (HDMI and DisplayPort). No lags, no black screen, no bugs.

I can also boot on Windows 10 and use my Nvidia RTX 3900 FE (located in my primary PCIe slot).

I'll report back here if I notice any issue with the RX 5700 XT on Catalina.

Everytime you boot into windows you swap manually the cables from one GPU to the other?

Pretty much yeah. I use a DP Switch.
