Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

[inapis.crazy]

Can someone succinctly explain the load line calibration option in the vision d bios and what it does and what is the best setting?

I was playing around with it and set it from auto to a few settings and settled on medium (the ‘low’ setting resulted in application crashes under sustained load). Temps in cinebench r20 have dropped a full 9 degrees at the same Vcore voltage. Just trying to understand. I’ve overclocked the 10700k to 5.1 GHz all core. In macOS, temps during a cinebench run were kinda hot at 85-86 degrees. I’m using a kraken z63 cooler, and macOS doesn’t have the benefit of adjusting the pump speed in response to temp. When I run cinebench in windows, same bios settings as above, temps were in the 70s but in windows I have the benefit of NZXT ramping up the pump/fan speed responsive to system temp.

Now with the load line calibration bios tweak, the system consumes less power and generates less heat under sustained load. I’m now getting a respectable 77 degrees @5.1 GHz overclocked in macOS. which is awesome, considering a real iMac20,1 (that is not overclocked to 5.1 GHz all core) hits 99 degrees and throttles down during a cinebench run. Thanks.

I'm no final authority but I can describe my novice understanding so far. LLC is used to counter Vdrop. Vdrop is the voltage drop you see when the processor is under load. You might set 1.4v as Vcore in BIOS but under load the processor might actually be at 1.3v. You can see this under HWinfo in Windows. You use LLC to deal with this Vdrop.

The ground is muddy because there are a lot of different variables for determining what voltage your processor is getting. VID is generally ignored because that's what the processor thinks it wants. VCore is what you fix and what the MB tries to give but it retains the right to adjust it if needed. VR Vout is generally the measurement of the voltage just before the processor gets it but not every motherboard has the ability to measure it. Vision G and Vision D should be able to measure VR VOUT.

One major issue is that most overclockers use an ASUS board for tuning this. Thus mapping ASUS LLC values to Gigabyte is tough.

We hope so.

Yup! Vermeer is coming and it is looking sweet.

Thanks!! I will research this further.

Please try SwitchResX to enable 4K60 if nothing else works. I purchased a license yesterday for my new Gigabyte B550 Vision D with an older AMD R9 GPU, and SwitchResX works wonderfully.

unfortunately I only get 2560x1440 @ 60Hz are you able to get 4k60 on your z490 Vision-D, could you test it, please?

Sorry for my poor English, use Google Translate
I recently installed macOS, the model used is iMac20,2, and USBInjectAll_v0.7.5 is used. Because there is no driver for the ax201 wireless network card, I did not notice that USB does not have HS14 at the time. I released a new Intel wireless network card driver, and then I started to try to drive Bluetooth and wifi. However, Bluetooth can't be driven anyhow, and then I found that there is no HS14 port in Hackintool.

To this end, I tried many methods but couldn't get it, and I didn't find the answer in my domestic forum. It took a long time to find here. This is because of the USBInjectAll problem, and then I also tried to use the USBInjectAll_0.7.6 you released. Although the HS14 port is displayed in Hackintool, it is still not in the IORegistry. In the computer system information, the Bluetooth still shows the message not found. , The same is true after changing the model to 20,1, I think it may not be perfect yet. In addition, if you use "iMac20,1_USBInjectAll_v0.7.5_z490.kext" in the forum on 20,1, it can be perfect. But it can only be used in 20,1.
These are some of the problems that I have encountered, and I hope they can be resolved in a follow-up update.

Hello @LX45682,

Welcome to the forum. We intentionally disabled HS14, but it is very easy to enable it. Simply disable SSDT-UIAC-VISION-D-V2.aml in OpenCore Configurator, and add SSDT-UIAC-VISION-D-HS14.aml attached below. Be sure to copy the file into OC/ACPI folder and add an entry in OpenCore Configurator.

How many hackintoshes are you gonna build lol. Have you or are you gonna create a Vision Dd B550 thread ?

This is my plan:

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

noup Does it happen on Hackintosh when connected to the SAME external enclosure? If you have another large drive, connect both to the MacBook Pro, transfer your files to the new drive and see if the new drive also exhibits the same problem on the Hackintosh.

As to how many Hackintoshes I'm going to build, well when there's an interesting new opportunity I cannot refuse, then I cannot refuse...

There are a couple of scripts to run which sorts out most issues. The latest beta versions of the apps now work without patching via the scripts. Probably Adobe working with Apple to remove Intel specific stuff out so that they will run on ARM. Some plugins don't work (yet) as they should, eg Topaz Denoise, even though they work on their own.

I noticed that your profile says TRX40 with Threadripper 3970X. Are macOS patches available now for both TRX40 and 3970X or are you using a Rube Goldberg machine that layers VM over VM?

That looks correct. The scaled resolution will be 2560x1440 @ 60Hz. On a 4K monitor we scale the graphics to 2560x1440 instead of displaying them at 3840x2160 (which would be too small to see).

Vermeer might make me build another one... especially if big Navi will be supported on Mac. I might do a small form factor AMD build though...

Also, have you seen this? Vision D RTX 3080 is coming. Far sexier than other boards I’ve seen thus far.

here’s to hope that a similar big Navi AIB comes too.
