Hi
@justdatruth
just one more thing... for your ALC Audio configuration did you read/try this post?

it seems interesting, but of course I haven't tried it yet. Give it a try I you want, and see if it helps!

Hi again,
So..... I’ve spent pretty much the last 48hrs setting up and testing my DAW software on the box and I’ve noticed a few things.
Thunderbolt seems to be working well now, I even managed to get my LG monitor to connect via thunderbolt. The PCIe related settings seemed to have helped ensuring reliable detection of thunderbolt devices, but at the expense of sleep functionality. Now when waking from sleep I don’t resume connection to attached devices.
Audio over DP came back, then disappeared again, I think I have an idea what is going on with that but need to investigate further. I’ll try one of the other methods
@kgp suggests in his guide. It’s really not a big issue for me.
Now for the biggest issue.
While I’m still getting great benchmarks 40k+ on geekbench and 2.4k+ on cine (at 4.5ghz), I noticed that performance in my audio applications was noticeably worse than on my 2011 iMac (i7 2600). This doesn’t appear to specific to OS X either, I get the same issue within my windows partition. As an example an audio project consuming 8% cpu power on my iMac requires closer to 20% on this build. Comparing this build to my iMac, 7900X spends far too long running at lower frequencies with normal applications, around 3ghz on the iMac vs 1.2-2ghz. If I run a cinebench test, it causes the cpu to run at max frequency and my DAW actually consumes LESS cpu power, far less!
This appears at least with my limited knowledge, to be a cpu power management issue.
If I disable speedshift in the bios, windows will run the cpu at whatever frequency I set but OS X seems to ignore the bios setting and attempts some sort of power management. A better approach I guess would be to be able to define cpu states, again there is software to this in windows, it seems like it could be achieved with a custom SSDT with this build, but again my knowledge is fairly limited so I could be way off base.
I hope that makes sense. I’ve done a few searches and power management/p-states appear to be a bit of problem with the Skylake-X platform. If anyone has any advice on how to disable power management in clover/osx or in relation to this, even if it’s to say I’ve misdiagnosed the issue, I’m happy to hear it!
