Apple only adds support for GPUs they use themselves. Which effectively is limited to what they want to support on the MacPro as Apple Silicon Mac use Apple's own GPUs. Navi 23 (6700 XT) was released before the Navi 22 (6600). As all Navi variants are very similar, this strongly indicates they...

Geekbench does not represent real world performance very well, a more consistent benchmark would be CB23 for example

Zen 3 should be running in 1:1 up to 1900MHz / 3800 MT/s. If you go over that the BIOS will set the fclock down. With a little luck you could get fclock to run manually at 2000 MHz, but might need some voltage tweaking. Setting the timings manually to 3800 would be the easiest and more stable...

I don't understand russian, but there are no drivers for the 6700 XT in macOS. People tried spoofing the device ID, but so far I never heard of anyone getting it to work.

The RX 6700 XT is not supported by macOS as it is a Navi 22 chip. macOS 11.4 added support for Navi 21 (6800/6900) and macOS 12.1 added support for Navi 23 (6600) so far. Also, some MSI 500 boards have BIOS issues preventing Monterey from booting.

Running them at 4133 gets you worse performance than running at 3800 due to fclock/mclock not being 1:1 anymore.

You should check your RAM settings, they currently run pretty low at JEDEC specs. You should check if they have an XMP profile for 3200 to 3800 MT/s.

The I211AT is currently not usable on Monterey. AppleIGB kext does not work reliably. Either use Big Sur or buy a supported NIC if you want to use ethernet on Monterey.

Add -v to the boot-args

There seems to be a regression in the 12.3 Beta crippling Navi 2 cards.

B550 only has Gen 3 lanes from the chipset. Only X570 also supports Gen 4 for all PCIe lanes. I think there is one B550 board that uses lanes from the x16 slot to provide 2 additional M.2 slots with Gen 4. But on most boards, the secondary M.2 runs only with Gen 3 from the chipset. I agree, the...

The Samsung NVMe SSD will result in long boot times on Monterey as the TRIM timeout is broken. On Big Sur and lower it was not noticeable as TRIM was just not performed for the most part. Also, MSI boards are a hit or miss regarding Monterey due to BIOS issues. Since you're using Zen 2 you...

Apple did some changes in Monterey that broke SmallTree. If you need Ethernet on Monterey, you'll have to buy a cheap, supported NIC. Be it a PCIe card or an USB dongle.

MSI is not recommended if you want to use macOS Monterey. Many MSI 500 boards have a BIOS issue that prevents Monterey from booting. Only workaround is using Zen 2 and a very old BIOS.

True, but like TRX40, there might be significant work required to get macOS to run bare metal.

@madvinegar The issue has been documented pretty well here: https://github.com/dortania/bugtracker/issues/192 It's an issue with most Samsung NVMe SSDs. On Big Sur you won't notice it (besides 8sec longer boot time than with other SSDs). Though since TRIM does not work correctly, your SSD might...

@Shaneee Not quite, although Threadripper CPUs are very similar to Epyc and the Sockets are physically identical, the platform isn't. Threadripper uses a chipset similar to Ryzen (TRX40 is basically X570), while Epyc is an SoC without a dedicated chipset. Threadripper Pro is more similar to...

I'd advise against using a Samsung NVMe SSD, their TRIM implementation is broken. TRIM will not work properly on Big Sur, and on Monterey the timeout does not work anymore so it will cause long boot times (like 2-3 minutes).
