X299 - Open Core support

[DrMacabre]

what issues are you running into?

I can make a clean install of mojave but as soon as i migrate my user account from my old SSD (Mojave+clover) i can't even boot back to the clean install. My first idea is i need to clean my old SSD of clover as they mention it in OC guide before trying to import my user. I walking on eggs here, yesterday i crashed my old probook with el capitan so the only OSX left is the clean install i'm currently using to write this and a windows 10 SSD. Also i don't have any sound but this is secondary and can probably be easily fixed later. I went to OC because it was my only hope to reinstall OSX without any working OSX around but i'm kinda lost as many others with all the SSDTs stuffs. Also most of you are now running catalina on sage 10g which doesn't help in my case.

I'm using unpatched BIOS 905 and CSM is still enabled since i can't see anything when i disable it. Doesn't seem to prevent anything. Is disabling CSM really mandatory ?

I think I've solved it. The limit was linked to the maximum capacity of Coffee Lake processors/platform of 64/128 GB. With new generation Intel processors that allow using 128/256 GB, in another forum, I found the solution, that I've not yet well understood ...

Yes, depending on you CPU you can add 128gb or 256gb above 6 cores but mine is 10 cores and i couldn't even get to the bios. The ram was working on the system it was coming from, i think it was a Z390 or something. The only option i could have tried was using some compatible ram to get to the bios and disable XMP to see if the corsair was working at a different clock but i didn't had my actual ram at the time and they guy who sold me the ram from took it back without making any problem. I hope you can make it work, i gave up about looking for a solution after a few days. What's really weird is that the 3600 or the 3000mhz LPX in 32gb are listed on the asus compatibilty chart but not the 3200...

Hello, after a day fooling around with opencore, it seems like i missed a few things, i can boot but as soon as i try to migrate my user from my old system, i can’t anymore . Please could anyone share an EFI folder for the asus ws x299 sage (not 10g) with a 7900x for mojave?

I can’t use the one from Izo1 as it seems made for catalina and i have no clue about what to do to make it work with mojave.

You need to use SMBIOS iMacPro1,1 for Mojave. MacPro7,1 is only for Catalina.

Sorry, I expressed myself badly. I'll list below the materials that I would have chosen following your build, indicating some doubt.
My build could be:
1. Motherboard: ASUS WS X299 Sage/10G. I don't know what BIOS will be on board on arrival, but I can flash the latest, right?
2. CPU Cooler: Fractal Design Celsius+ S36; It's silent? Can I overclock CPU with that?
3. CPU: Intel i9-10940X: I'd like to have the option to expand the RAM to 256GB in the future and I've read that it's easiest to overclock as 10980xe
4. RAM 4x32GB Corsair Vengeance 3200
5. SSD: Sabrent Rocket Nvme PCIe 4.0 M.2 2280 1T + 1 unit 8TB U.2 micron or similar + various HDD
6. GPU: Sapphire Radeon VII
7. TB3: ??? I maint to Gigabyte Titan Ridge Thunderbolt but now it is unfindable
8. WiFi/BT: as Broadcom BCM94360CD I have found various models, among which I cannot choose; I also found this: MQUPIN FENVI T919 Scheda Wireless BCM94360CD;
9. PSU: Corsair RM850X: is it enough to power the system even in overclocking?
10. case: CoolerMaster Cosmos C700P

I forgot something?
Thanks for your time

1- My CPU ( only ) use 400w under overclocking @4.9Ghz. 850w might be too low. ( I have a 1200W PSU )

2- Contrary to the popular belief, 360 AIO CPU are perfectly fine to do high Overclocking.
Checkout at my scores in Cinebench without delidding. ( AIO Thermalake FloeRing 360)

I've been connecting to the Thunderbolt header. Maybe I mistakenly understood that the pin jumping was for Designare users who also had an add-in card. Maybe I'm getting carried away here-- but if the header is not required for us-could it be possible to have a 2nd Titan Ridge? (!) I'd love...

Been seeing a lot of people just asking for other peoples EFIs to get started or referring to izo1s or shaels EFI. Unfortunately their EFis are a little outdated and are tailored to their specific builds so it's not ideal to just copy their EFI and expect it to work.

While I highly recommend reviewing the OpenCore vanilla guide linked in post 1,

I've updated the BASE-EFI folder in my github that should be valid for all ASUS X299 boards.
Instructions can be found here: https://github.com/shinoki7/Asus-X299-Hackintosh#base-efi-configuration

Updates:
1. Added USBInjectAll.kext and enabled XhciPortLimit (Kernel-Quirks).
2. Added IntelMausi.kext for Ethernet.
3. Changed alc-id to 1.
4. Removed TSCAdjustReset kext and moved it to here. https://github.com/shinoki7/Asus-X299-Hackintosh/tree/master/Kexts/TSCAdjustReset. These are already configured by core count. Just rename the file and remove '-(corecount) and copy the file to your efi folder under EFI-OC-Kexts.

2. Once properly setup, it's highly advised to create your own USB kext.

Once people have created their own, please let me know so I can add it to my GitHub

Yes that’s where i started, i’ve been following kgb’s guide for the sage 10 but was unable to boot my old os after swapping the board.

Not in my case, i went straight to OC guide and followed all the steps. Unfortunately, i’ve never been too familiar with ssdt on my previous builds, chameleon or clover has always made everything much easier.

In your opinion should I change the RAM to corsair vengeance 32 gb with different clock?

Check the compatibility chart on asus website, i can’t load it right now, you have a different CPU, may be you are going to be more lucky than i was.

RAM's most important part is how fast it can move data, so timing and MHz matter. CL16 and below @ 3600 are expensive in terms of RAM. CL14 @ 3600 is much more expensive.

Having fast ram makes things feel speedier, but I'm pretty happy with 3200MHz @ CL16. Better quality RAM like Samsung B-Die (which I think they stopped manufacturing) is still expensive.
