How to build your own iMac Pro [Successful Build/Extended Guide]

[kgp]

Hello, KGP! Need your help!..
I builded same hack, according to your guide, with small difference. 7940x, ddr4 crucial elite3000, GA1080ti,x299primeDeluxe,970evo/apfs. System test 10.13.6 and 10.13.6SU. bios same you guide
All work good. Premiere with 4k video and lots of effects, working perfect. but if i send a queue render to adobe media encoder , hack freezes and no longer responds except reboot. all bench work good. render in ffmbc same freezes. CPU use 30-50%max

1.) What about AVX and AVX-512 offsets in your BIOS settings?
2.) Flash your mobo with actual BIOS firmware (1503)
3.) Disable MSR lock in BIOS settings
4.) Disable xcpm_core_scope_msrs in config.plist
5.) Uncheck KernelXCPM in config.plist! Skylake-X works native!
6.) Uncheck AppleIntelCPUPM in config.plist
7.) Remove FakeCPUID from config.plist
8.) Add SmUUID to config.plist
9.) SSDT-X299-HDEF.aml will never work without SSDT-DTPG.aml
10.) Remove drivers64 directory from EFI-Folder
11.) Update Clover or use my actual EFI-Folder distribution

Did you ever read my guide? Does not look like. All works good? If so, that would be really a miracle...

Good luck,

KGP

1.) avx set to 3
2.) avx 512 to 2
3.) msr disable
4.) tscaadjus fix and use
5.) bois last 1503
6.) Clover update

if I load cpu with a 100% script. then intelpowergadget shows 200-240wt load and works in this mode for hours. if i start rendering adobe , computer hangs in 5-10 minutes

@kgp , Hi KGP, I just switched my 1080ti to SAPPHIRE NITRO+ Radeon RX Vega 64, and changed to the water cooler too. it works fine, but just one problem, it's black screen after sleep. my main board is x299 Gigabyte aorus gaming 9, CPU is 7940x. Here is my clover EFI file and exported IORegistryExplorer file. could you please guide me how to solve this black screen problem? Thanks!

Talking about a black screen on wake... can you access the computer remotely? I guess the latter will not be the case.

1.) I clearly state in my guide not to use MatchOS entries for kext and kernel patches, if you use one, you should use MatchOS entries anywhere.
2.) What for do you use a port limit patches, while implemented a kext with 7 HS ports, only?
3.) How do you expect the kext to work without adding any SSP ports?
4.) Moreover four HS ports in your kext have UsbConnector number 3 (USB3.0) and the respective SSP ports therefore would be compulsory.
5.) Are you using a ASUS Aquantia 10GB NIC? Or what is the reason for enabling the AppleEthernetAquantiaAqtion.kext patch?
6.) What for do you use the NVIDIA com.apple.driver.AppleHDAController.kext patch having a Vega?
7.) AppleALC is outdated.
8.) When using SSDT-X299-Vega you should also use SSDT-X299-HDEF
9.) Remove "drivers64" directory
10.) Clover is a mess and outdated, implemented efi-files are from February, June and November 2018. No consistent Clover build..

etc.

Anyone using Premiere Pro here with a Vega FE?

I had export system freezes with CC2018 and just tried CC2019 and this issue hasn't been fixed.

Basically any timeline with OpenCL, Metal or Software Only renderer and exporting to hardware or software H264 from premiere freezes the whole system.

This can be easily replicated if you have Chrome open with 4k YT video playing (try multiple windows/tabs) while exporting

My friends,

From today, I will be on holidays and hardly able to connect for some days.

Enjoy, have fun and thanks for your patience,

Thanks, KGP, the MatchOS entries was made by FB-Patcher, I just removed it and related kext. your SSDT-X299-HDEF not work for me, my sound chip is ALC1220, not S1220. the drivers64 folder removed and rebuild official clover. but black screen still happen after sleep. Tomorrow I will try to use HDMI to connect my 32UD99 monitor, now it's connected by DP, might it's the main reason of black screen?

No.. both DP and HDMI should work flawless including sleep /wake, always supposed that you use Whatevergreen.kext.

New BIOS for Designare EX, supporting the newest X299 chips.

I think they will be going on sale November 12 or later this month. I'm eyeing the i9-9980XE
