Gigabyte Z390 M Gaming build with working NVRAM

I tried but it still doesn't work.
I just made a video and put it on youtube for you to check.

You are getting a graphics error.

What kind of Vega 56 are you using?
Is your IGPU enabled or disabled?
How are your monitors connected?

What is Best Vega 64 for Hackintosh!

I have a Sapphire RX Vega 64 (https://www.newegg.com/Product/Product.aspx?Item=N82E16814202326) - it crashes randomly, usually under no load, I can run Luxmark for 30 minutes doing a stress test and it's fine. OSX loses connection to the graphics card and cannot restart it, screens goes black, I...

@arvinsim and @k1ngJu4n have the Vega 64 versions of your video card and were unable to get it to work right.

I don't know how to get that card to work. The port layout deviates too far from reference.

My Gigabyte Z390 M Gaming is extremely reliable now. I wouldn't have done this write up if I felt the motherboard was unreliable.

I was not trying to insinuate otherwise I appreciate everything you do mate!

You're going to have to get a PCI-e adaptor to use your Apple Wi-Fi/Bluetooth card. Stupid Gigabyte whitelists the CNVi slot to only work with Intel CNVi cards...

If you want Sidecar, you can just switch to iMac19,1 system definition and enable IGPU. It should run equally as well. I chose iMacPro1,1 for simplicity because I don't have a Sidecar compatible iPad.

My card is a PCIE card with a USB header that connects to F_USB1

I had a hunch it was due to the 5700 XT... Is your Z390 M Gaming reliable with your older video card?

"Built-In" vs "Slot-0" is just cosmetic. You can edit it to say almost anything in config.plist > Devices > Properties.

Not sure about DRAM Power... Are both systems using the same SMC emulator?

Hmm... Weird...

dart=0 is used to circumvent VT-d.
slide=0 is related to NVRAM.
agdpmod=pikera is a workaround for GPU black screen condition.
darkwake=0 is to change the darkwake behavior.

Both systems are set to iMac Pro 1,1

The 5700XT seems to be stable now in the older system,m with those Boot arguments.

As for setting things to iMac 19.1, I don't think that is and Option using the i9-9900KF as it has no IGPU.

Both systems seems to be running totally stable I'm going to add the Boot arguments to the Z390 M Gaming system and put the 5700 XT back into it and see if it works. They have both been running for about 15 Hours now with no issues during idle.

F_USB1 is how I have the USB ports configured so Bluetooth should be working for you.

Yes, with "F" CPUs, iMacPro1,1 is the best option. I have an i5-9400F.

I'm anxiously awaiting your test results with the 5700 XT.

On the ACPI tab in the drop tables I have DMAR on my ASUS system, and I don't have it on the Gigabyte Should I? I'm not sure what it does.

Also on the Gigabyte system currently XMP 1 is enabled in BIOS and Clover Boot tab says it is set to 1 instead of auto.

DMAR should be another method to circumvent issues with VT-d. I've never needed it on any of my builds... If you thing VT-d is an issue, it's probably better to disable it from BIOS.

If the system is stable with your current XMP settings, I would just leave it as-is.

Ok I have them swapped back and the Gigabyte with the 5700 XT is idling.

While that is going on I wonder if the reason there is no DRAM measurement on the 9900KF is because of the lack of. IGPU perhaps?


Also what would you recommend as a motherboard for a full ATX build with TB3 "hot plug capable"

What do you mean "DRAM measurement"?

What do you mean "DRAM measurement"?

On the Intel Power gadget on my ASUS system with the i9-9900K, it has a power reading for DRAM


On the Gigabyte system with the i9-9900KF it doesn't have this. So I'm wondering if it is measuring it for something having to do with the IGPU.


Also, just crossed the 5 minute barrier on the Gigabyte system, and it hasn't locked up yet.
