[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[rj510]

Serial numbers on some 27-inch models end in JV3Q. And platform ID is 0x3E980003 with AMD 580X driving the display.

Any knowledge of BIOS versions and release dates? Or, Board IDs?

Also, my intention was to disable the IGPU only when applying the 10.14.4 update, and to enable it afterwards. After the update, we no longer need "device-id = 0x3E9B" because the real device ID 0x3E98 is supported in 10.14.4.

Not sure I want to mess with it while everything is working. But would be nice not to have to inject the device ID if it is supported. Although, I'm not sure what benefit would come with this. Let us know what you find out with this. I'm also wondering about changing serial number and getting recognition of the CPU natively in the next few weeks. I would have to go through the iCloud, iMessage and Apple ID stuff again. I'll keep me ear to the ground for this one!

This being your first post, welcome to the forum! Interesting indeed that the i5-9600K has been recognized since 10.14.2.

The black screen problem you describe seems suspiciously like a BIOS --> Initial Display Output setting. The fact that BIOS screen appears with onboard HDMI and USB-C indicates that Initial Display Output is currently set to IGFX. Try changing that to PCIe 1 Slot assuming that your Sapphire RX580 is in that slot.

It currently is set to PCIe 1 and it makes no difference if it is IGFX, which I did try a couple of times over the past few months. Even with BIOS --> Initial Display Output --> PCIe 1 Slot selected only onboard video ports display BIOS screen. It is strange and I haven't been able to figure it out. If I need to access the BIOS or want to boot into Windows I just swap the cable to the onboard ports temporarily.

Ok Thanks... I will try now. What is your clover version at the moment? 4862? If you have a most recent one then 4862 where did you downloaded that?

Thank you!

I believe that's the one I have -- can verify later this evening. It was downloaded from SourceForge.

I just saw this Apple page (https://support.apple.com/en-us/HT201634) and it shows the iMac 19,1 as the 21.5" and the iMac 19,2 is the 27" (not vice versa as written in an earlier post). Apparently for the iMac 19,2 there are i9 CPU options. Perhaps those extra MMMM models numbers I found here (MMMx, where x can vary) are based on the chosen options within the base iMac 19,2 model.

Yeah. I found a serial number that ends in P.

I also mentioned in one of my earlier posts that according to apples own support document. 19,1 should be 21.5 inch and 19,2 should be 27 inch.

So iMac 27inch are shipping with 19,1? We’re you able to get one for an iMac 21.5?

Yes, but these may be limited to Intel i5 models. More data points are needed to draw a conclusion.

We’re you able to get one for an iMac 21.5?

They have one on display, but I didn't touch it.

Hey Guys thanks for all your help, I have a problem, a tow minutes, the messages of:
An error occurred validating the installer data, the download is damage or uncompleted.
Any Ideas? Thanks for your help.

you could try as it asks, re create the USB installer.

SanDisk make good USB installers.

Thanks for your answer man. I'm using a 16GB USB 3 SanDisk. Is this a typical problem? I mean the USB?
Thanks again.
