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

[CaseySJ]

@billybuck092, awesome -- thank you for sharing your experience!

 

[CaseySJ]

...Im super happy with my new monitor!!

Everything is super crisp and sharp! Today I worked at Photoshop and fcpx and the experience with this monitor was amazing!!

Glad to hear it! So no need to fuss with a TB3 connection??

Glad to hear it! So no need to fuss with a TB3 connection??

Not really I think. But I will try it out just to share my results with other ppl who are interested for 5k monitors over tb connection.

Because DisplayPort 1.2 supports 4K at 60Hz, most 4K monitors are DP 1.2 (even if they have a USB-C video input [not Thunderbolt]). When we step up to 5K and 8K monitors we need DP 1.4. The Alpine Ridge Thunderbolt controller does not support DP 1.4. But Titan Ridge on the Designare fully supports DP 1.4.

Apple, however, plays a trick with 5K monitors by sending two DP 1.2 streams to the monitor at the same time.

@CaseySJ - Ahhh! I think I understand now. Thank you for all the clarification!

@skroutz999 - did you buy an LG 34Wk95U? I absolutely love that monitor, but I've read that many people had image retention (maybe burn-in) due to the "nano" part of the nano IPS technology. I'm curious what your experience will be over the next few weeks. If you can, keep us updated on how you like it!

You guys have tremendously helped me in getting the 128GB of RAM working. However, running MemTest I ran into some problems ... these are the results:

*** Address Test Failed *** One or more DIMM address lines are non-functional.

This is what my configuration on Clover looks like (it goes on with Slot 6 and 7, as I have full 128GB of memory installed):

To be sure: this is the Memtest I ran (as recommended in the trouble shooting guide):

MemTest for Mac OS X Tests your RAM

I don't think the RAM is not working hardware wise, as I also did a full memory test running windows and no mistakes were showing up. Could these mistakes be just due to the wrong attribution of 8 slots vs the actual 4 slots? Did you also do that Memtest? What were the results?

I just ran a test in single user mode which has been on my todo list for awhile. I ran memtest all 1 for one round of testing.

It took almost 5 hours to complete but I did not get any errors at any point.

@CaseySJ - Ahhh! I think I understand now. Thank you for all the clarification!

@skroutz999 - did you buy an LG 34Wk95U? I absolutely love that monitor, but I've read that many people had image retention (maybe burn-in) due to the "nano" part of the nano IPS technology. I'm curious what your experience will be over the next few weeks. If you can, keep us updated on how you like it!

I searched a lot about this monitor and It's actually the first time I hear about this issue. Time will tell though. I will keep you updated.

I thought I had done everything right and everything seemed to work fine with the changes so that Bluetooth would be taken into account as an internal port. This was until this morning when Bluetooth is unavailable in the menu and appears as disabled in the system preferences. No matter how many times I click on "activate", nothing happens. However the bluetooth module is well detected in about this Mac. Did I do something wrong? Can we fix this or should I use a Bluetooth dongle instead?

 

[faithie999]

here's a strange one. never encountered this before.
I have started using Samsung Bar usb sticks. they have a sturdy metal body.
the USB ports on the top of my case (a ThermalTake of some variety) have their metal perimeter flush with the top of the case. when I touch the Bar usb to the metal perimeter as I'm inserting it, the computer immediately reboots. using any other usb stick does not cause the reboot, even though there is a metal perimeter on the usb stick. I used a coin to "short" the two sides of the USB port but that doesn't cause a reboot. it's something intrinsic to the Bar usb stick.
so I thought I would try using a USB Hub plugged into the case's top port. the hub I have has the metal perimeter of the ports slightly recessed into the plastic housing of the hub, so 4 times out of 5 I'm able to insert the Bar without causing a reboot. however, if I insert it just right (wrong!) the Bar housing touches the metal inside the port and causes the reboot.

Thanks for checking it out! If you look two post further, I have found out that there was not Memtest problem showing up on my backup. So, probably FakeSMC replacement with VirtualSMC or some of the other modifications of "going the extra mile" has caused it.
Would you share your full settings, including Clover? Did you set up iMac Pro or iMac 19,1?

I'm in love with this app called MonitorControl, using your keyboard (works with Magic Kb too) you can control the brightness and volume of your display IF it supports DDC. Can't recommend it enough. Even if you use a real Mac with a Non-Apple external display... this is gold. In case you use brew, it's on cask too: brew cask install monitorcontrol
