That's been my experience as well. Didn't want to mention it until more data became available, but it now looks like RX 4xx and 5xx series may already be optimized on macOS so no further optimization is possible. Will update the Radeon Boost micro-guide.
I can confirm this. My Open CL score was worse with Radeonboost.kext and metal the same on geekbench 5. RX580 nitro+

Here's the reply from adamsmasher who lives nearby in Northern California:
I'm also facing issues from Europe and have to use a VPN in order to access the domain.

** Micro-Guide: Radeon Speed Boost **
for Vega 56/64, Radeon VII, RX 5500/XT, RX 5700/XT
Please do not quote this micro-guide in its entirely. Post a link instead.​

CaseySJ, interesting question, I have two VEGA 64's one in slot one and one in slot 2. Do you think I should be loading both injection SSDTs in order to provide injections to both cards or does this not work like that??

Any insight would be appreciated, thanks

@scottkendall, have you tried the minimal 3 patch approach on the active partition of the Rev1?

2727->3737 at offset 0x35 (decimal 53)
A0 -> 20 at offset 0x81 (decimal 129)
FFFFFFFF -> 8680D315 (or whatever your controller device-id is, byte reversed) at offset 0xBA0 (decimal 2976)

It has worked on all the Alpine Ridge firmware I've tried so far (Intel Hades Canyon15d3 and Asrock Z370 itx/ac 15c0)
Hi @dgsga,

thanks again for the hint. I tried to apply those patches and was able to find the first two. The data at 0xBA0 looks like it's not the one that needs patching (I attached the section in case someone is willing to have a look). Where do those values come from? I'm unable to find any other reference mentioning those offsets / values so far.

[EDIT]: I decided to move this topic to an other thread since it doesn't fit in here very well.

My 590's metal scores were 2.74% worst with radeon booster kext

Osy86's Thunderbolt patcher (tbpatch) tool is awesome, but it won't work out of the box. We first need to configure and install the TbtOnPch SSDT, reboot, ensure that Thunderbolt Bus appears, and then run the patcher to modify the Thunderbolt chip. On an Alpine Ridge system, you might wonder why it's even necessary to flash the firmware when an SSDT will do the job! @Elias64Fr has a fully working Thunderbolt Bus on his Asus Maximus X Hero Maximus IX Extreme (with on-board Alpine Ridge). Firmware flashing is not necessarily required for on-board Alpine Ridge controllers.

Correction: Elias has Maximus IX Extreme.
Is this a light at the end of the tunnel for a non-external, software only, patching method to swap out the NVM on our built in Titan Ridge chips?? Potentially??

Yes -- one for each slot.

That applies to Alpine Ridge. For Titan Ridge, this post still applies.
