How to extend the iMac Pro to X99 [Successful Build/Extended Guide]

[kgp]

weird on my board all my big slots say x16

I put the card in slot 1 but still only showing 8x and in says slot 4

do i need to update or refresh the driver or something?View attachment 288884

Look at your Graphics/Displays System Report!!!!

Important Notification for @ALL
Full PCI Controller Implementation established for the ASUS X99-A II

Based on already existing X99 and X299 PCI Controller Implementations formerly developed by @nmano, @TheOfficialGypsy and @shilohh, I finally achieved now also a complete PCI Controller implementation for the ASUS X99-A II and my particular system configuration.

At first place, the approach bases on an ACPI DSDT Replacement Patch Table Implementation in the config.plist of the distributed EFI-Folder. Note that by means of this ACPI Table detailed below, one already achieves full sleep/wake functionality with the ASUS X99-A II, bit very likely also with any other X99 mainboard different from the ASUS X99-A II.

For details and explanations see Section E.9.3) of the the originating post/guide.

At second place, the successful PCI Controller Implementation has been achieved by means of a newly developed SSDT-ASUS-X99-A-II.aml, which further bases on the the following constraints and assumptions.

1.) Gigabyte Nvidia GeForce GTX 1080 Ti 11GB Extreme Edition in PCIe Slot 0. Note that I just use one LG 38UC99-W

monitor, connected via Display Port (DP). Further note that HDMI/DP audio just works when connecting the monitor with the second Nvidia Display Port from the left.​

2.) Inateck KTU3FR-502U XHC 7-Port USB3.0 Controller in PCIe Slot 3.

3.) OSX WIFI Broadcom BCM94360CD 802.11 a/b/g/n/ac + Bluetooth 4.0 Controller in PCIe Slot 4.

For deviating build configurations and PCIe slot populations, the SSDT-ASUS-X99-A-II.aml has to be modified and adopted correspondingly by means of MaciASL and the IORegistryExplorer.



Else, the SSDT-ASUS-X99-A-II.aml attached below, considers also all on-board PCI controllers of the ASUS X99-A II.

Note that in line with the SSDT-ASUS-X99-A-II.aml, one also requires the SSDT-XOSI.aml in /EFI/CLOVER/ACPI/patched.

I will wait on your estimated user feedback, before officially implementing the entire part in the originating post/guide.

Enjoy and have fun!

Wrong screenshot. before i got to 8x and now its 16x but all i did was reseat the gpu...

Still getting reboots when i run a gpu intesive program. have tried goging up and down on driver version currently at 117 right now.

With the reboots im not sure how i can trouble shoot this. some times i can run gpu intisive program for more that 10 min then reboot and sometimes it reboots within 30 sec of running.

Feels like im grabbing at air...

Will this also work with the x99 deluxeii?

Will this also work with the x99 deluxeii?

You might have to remove all Inateck and OSX WIFI related parts from the SSDT-ASUS-X99-A-II.aml and add the implementation of the X99 Deluxe II build-in Bluetooth and WIFI Controller. Note that also the TBEX 3 PCIe controller is not yet implemented. If you use your GPU in a PCIe slot different from PCIe Slot 0, you might also have to adopt and modify the HDEF, GFX1 and HDAU parts in SSDT-ASUS-X99-A-II.aml, respectively.

How to enable Hardware Acceleration in Web Browsers with unofficially supported Nvidia GPUs. In, Chrome I can see the hardware acceleration is enabled but still while playing Youtube videos, I see my Cpu using 50% of resources.

And why your CPU should run at 100% while playing Youtube videos? This anyway would collapse your system.. The video acceleration should be performed by your GPU.

Yes, that's what my concern is. The video acceleration is not being performed by my GPU. It uses CPU resources rather than GPU.

Do you have your GPU in a PCIe slot that also supports x16 (16 PCIe lanes)?
