Hi all. I have a problem...
Hardware:
ASRock x99 Extreme 4
Intel Xeon E5 2658 v3 ES
16 gb 2133 corsair
GTX 1080 inno3d x2
Mac OS 10.13.6 (17G5019)
SMBIOS Mac Pro 6.1
latest Nvidia web driver installed
video card is working fine in system no freezes or lags but only in UI, but in benchmarks my 1080 really sucks.
CPUPower Management working fine, usb, all working fine except this, maybe someone knows what is the reason?View attachment 384130View attachment 384131
Sell your Nvidia and go for a Vega 56 or 64.

Good luck,

I have to agree with @kgp performance on my 1080ti has degraded on every security update. Saving up so I to can go the AMD route to end my frustration.

New 10.13.6 SU EFI-Folder

New EFI-Folder EFI-X99-10.13.6-SU-Release-iMacPro1,1-020219.zip with Clover_v2.4k_r4862, yet disabled USB port limit patch and macOS independent XCPM_performance patch valid for 10.13.4+ and all version of 10.14.

The correct macOS independent XCPM_performance patch valid for 10.13.4+ and all 10.14 versions reads:

Code:
Find:    C1E30848 63D389D0 48C1EA20 B99901
Replace: C1E308B8 00FF0000 31D29090 B99901
Fully vanilla EFI-Folder that should work with 10.13.4+ and all versions of 10.14, always provided that one also uses a truncated 15-port XHC USB kext in addition, with disabled USB port limit patch in the config.plist (default).

Enjoy and have fun,

Native Nvram Work ASUS X99 Deluxe @dgsga

"@D-F Just thought I'd throw my research into the mix. I have found that you can enable NVRAM writes in Asus AptioV bioses my replacing the NvramSmi SMM module with the combined SMM/DXE NvramSmi module (same GUID) from older bioses that allow NVRAM writes. You also need to delete the NvramSmiDxe driver module when you do this replacement. Unfortunately this only seems to work for Asus boards. Have tried using the combined SMM/DXE module in ASRock bioses but no go. So it seems to be that NvramSmi implementation is where the issue lies, unfortunately I don't know how to proceed from here..."

What I've done, using uefi toold i've deleted NvramSmiDxe GUID 54B070F3-9EB8-47CC-ADAF-39029C853CBB from my asus x99 bios then replaced with NvramSmi GUID 842A454A-75E5-408B-8B1C-36420E4E3F21 Replace as is w/ z170nvramsmi.ffs (extracted as is from Asus Z170 deluxe bios 1801).

For now nvram is working without any problem, be back soon with updates !

Well I guess that I can say that regardless of any body can say, I'm proud of my self cause I still can follow instructions. And here are the results after doing so tweaks to the system and creating a SSDT.aml file and placed it at the proper place as been said. Thanks to the knowledgeable person that create this guide and the contribution of others making comments and results finding I have come up with some great findings and here are they. Now most definitely this results and future tweaks will motivate me to buy a VEGA 64 to have a complete also close an iMacPro1,1. Ever since my initial setup I been using iMacPro1,1 system definition and they have stick Mojave and now High Sierra, I decide to stick w/ high Sierra cause drivers acceleration in which Mojave don't have w/ Nvidia, regardless on high Sierra the Nvidia card don't perform well on FCX pro neither DaVinci there are 3 reasons now to change to AMD. And regardless my actions I'm still going to do some DONATION!!. stay tune.

Congrats to your system and build! And congrats that you managed everything by yourself! You can be really proud of yourself!
