    Help with power management for Gigabyte X299 Designare EX

    I do not own this board anymore. I never got TB hotplug to work on it, and AFAIK no one has ever managed to do so on it. The main iMacPro thread has extensive information about this board and how to set it up

    Edit: I had found a backup of one which I'm pretty sure used to work. It does: Scope (_SB.PC02.BR2C) { Scope (SL07) { Name (_STA, Zero) // _STA: Status } Scope (PEGP) { Device (EGP0) However, looking at the original...

    Can someone help me adapt the Vega Frontier, I now run both the nvidia 1080Ti and AMD Vega in this box and moved the Frontier to a different slot which is shared with the TB3 PCIe bus. The Vega used to be in the PC01.BR1A acpi path, now it is in PC02. But in PC02 you also have BR2A and BR2C. I...

    still interested to read about how high your CPU will go temperature wise when you run the Prime95 test, if you have an AVX offset of only 2/3, I'm guessing it will get *very* hot regardless of your cooling system. Now mine is nowhere as good as yours, still 2x360mm rad EK, but over 4.1Ghz for...

    You went over 100C whenever the CPU reached 4.8GHz, I'm not sure I'd like to try that in real life. Have you tried with Prime95.exe Torture test -> small FFTs? what temperature do you get? I had to set the AVX2/AVX3 offset to -6 to not go over 100C (and even at 4.1GHz, it's over 420W on the CPU!!)

    I still have a USB macos 10.13.3 installation disk, I've kept it preciously in case I ad to replace my motherboard. Happy to make a dump of it for those hoping to enable their Aquantia 10gig network card.

    The LG 5K2K let you set the Thunderbolt input to use DP 1.4. Using a MacBook Pro (also Titan Ridge), this leads to a black screen; but I've read report that DP1.4 wasn't supported on the MBP. However, I just got a Lenovo X1 extreme, which also has a Titan Ridge chipset; with the LG 5K2K...

    Yeah, 4xPCIe lanes shared by everything on the PCH, including the M.2 slot which is using 4 lanes all by itself already. Add the wifi card, USB and what else.

    Likely because someone look at the numbers, see where it can be connected (PCH) and realise that it would make zero difference in actual use, and so save 2c per boards.

    what's the difference? that "update" is the latest BIOS.

    What do you have in /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d ? When you run: ioreg -lw0 | grep IODisplayPrefsKey what do you get? Also, maybe try enabling the pref instead: sudo defaults write /Library/Preferences/com.apple.windowserver.plist...

    Yeah, all the other resolutions set the screen to 3440x1440 which looks awful That's what the <key>DisplayPixelDimensions</key> <data> AAAUAAAACHA= </data> fixes. It's trivial to remove SwitchResX. Start the SwitchResX app, in the top left "ScreenResX" menu (on the left of...

    Fully uninstall ScreenResX. My guess is thst you set the preference to always show the resolution. When you set a scaled resolution, what real resolution is the screen set at? 34401440 or 51202160? You see this in the screen settings, preferences second page down.

    I added a thermaltake thermometer to my watercooling loop. It serves no purpose as the AMD always reads 2C over the water temperature. I don't know how they could manage their cooler to be so ineffective and so noisy.
