Asus X299 - Support

[tonzone]

Someone told me the issue with the i9 9820X has been solved in Clover 5028.
Can you or anyone else test this out please?
I currently don't have the same CPU at hand.

Thanks a lot!

Yes, zzmadd - great news! You can see the progress on this thread from page 5: https://www.tonymacx86.com/threads/i9-9820x-kernel-panic-on-install.269096/page-5
So we have not think about all newer 9xxx-Skylake CPUs, thank to Florin9doi!

I have checked frequencies multiple times and I saw system properly clocks the CPU correctly. In generale usage (SSE instructions) max frequencies spike to 5GHz as tuned in the BIOS and in Cinebench (AVX intensive) it operates according to offsets. I suppose the same behavior occurs in any app according to the instructions in use.

@zzmadd

Also, KGP had this discussion many times in the original X299 guide. If AVX didn't work, we wouldn't have to create the offsets. The KP we get at 0 offsets suggest that AVX is being used and pushing the system into unstable frequencies. If AVX didn't work, there would be no need for the offset as it would never come into play.

It's not unstable because you use AVX BUT because when you use AVX MacOS always runs any app at any time with such negative offset. If you drop the frequencies by such offset and set AVX to zero than it's the same.
if the system in the two scenarios behaves differently is just because of random better tuned voltages that are auto-adjusted by the bios. But that's random, you can have AVX to zero and lower frequencies and set a proper voltage yourself.

AVX doesn't work in MacOS. It's like dropping frequencies of the cores as it intervenes for all apps all the time and not only on those using the instruction set.

I don't agree. Apple uses many Intel instructions out of the box. We just never see it with real Macs because they don't have a BIOS to look at.

Obviously avx is fully supported https://github.com/apple/darwin-xnu...281fc08ae024145e84df927/osfmk/i386/fpu.c#L176 .

For avx power management, you need to look at xcpm. Pike Alpha was going to disassemble all of it and make an opensource library then he got a threat message and could not continue.

People need to remember hackintoshes are not real macs. Work needs to be done to make power management work.

I wasn't talking about support, I was saying Apple uses and someone else said macOS doesn't.

There's a lot going on with macOS on real Macs that we don't really know about as you said, we're not using real Macs.

i have instant wake issue.

if i click Sleep , my pc will go to sleep and then instant wakeup. so i need to click Sleep buttion again and it's ok.

custom USB already created.

anyone have the same issue?

Sleep is one of the issues that you should just give up on Hackintoshes. Whatever you do, something is not going to go well.

I tried really hard to fix sleep, and I can't wake it up with Bluetooth devices and when it does wake up, the USB drives are ejected.

I just gave up and leave it on or shut it down. It takes too much work to do ACPI configuration.

Just updated to 10.14.6
Easy update, so far so good!

It's worth noting, as many probably know, Clover 5018 doesn't have Aptiomemoryfix and no longer uses Driversuefi-64 folder and instead, just puts the drivers into a UEFI folder under the Drivers folder.

This worried me at first, but I replaced everything and added OsxAptioFix3Drv, did a test boot, and with success updated the OS. Everything seems to be working fine here.

From my many tests, DaVinci Resolve on MacOS uses AVX during decode of RED Helium footage. iTunes also seems to use AVX, not sure why. I may be wrong and misunderstanding how AVX calls work, but without AVX offsets I can boot fine until I try iTunes or playing RED footage DaVinci Resolve. Other things trigger KP without AVX offset, but those ones are repeatable.

iTunes links against Accelerate.framework which contains vecLib.framework. If you look at the instructions in /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libvDSP.dylib, lots of ymm and zmm register usage, https://forums.anandtech.com/thread...are-using-avx-and-avx2.2498660/#post-38722059 .

It's years I don't own a Mac.
All Intel Core simply have AVX not recognised.
