Mac mini 2012 + Rx480 | Need some help please always freeze

Recommended Posts

Hello,

 

Just finished my eGPU setup but there is a lot of problem prevent it operating normally. Before I get Rx480 I try with ATI HD 5850 everything is easy, no modification at all windows 10 auto find driver and run stable. That's is why I go for Rx480.... here nightmare begin

 

My Current system is

Mac mini 2012 -> Connect Monitor B

Highpoint RocketStor 6361A

XFX Rx480 GTR Black Edition -> Connect Monitor A

 

 

Let's start with mac side.

I setup clean install macOS sierra with Goalque's Auto eGPU, everything fine. Reboot.

During boot screen my screen flick (Monitor A eGPU) then eGPU fan whirl up and system freeze.

 

Next try, I unplug Monitor A that connect with eGPU. macOS boot normally show Intel HD 4000 and R9 XXX then plug monitor A. Everything works! But Unigine benchmark seem to crash every time but LuxMark work fine.

 

Problem is next restart it freeze again, I have to un-plug HDMI and re-plug every time it boot.

This is not optimal, is there a solution?

 

Windows 10 side is a Horror

When I use HD 5850 there is nothing to do at all, works perfectly except HD4000.

Now with Rx480

 

First - I install Crimson 16.10 .... Error 43 = Reinstall driver / Windows not fix this (FAIL)

Second - Reinstall Windows BOOTCAMP as UEFI = Black screen / HD4000 not working at all  (both screen unusable/no fix possible) (FAIL)

 

Third - I change to Crimson 10.7.1 non WHQL .... Intel HD 4000 Works / Rx480 Error 12

With Error 12, I use DSDT Override - Kaboom!

HD4000 Stop working but Rx480 Manage to boot with AMD Xconnect, BUT after few second monitor down system freeze and reboot a short while.

 

Is anyone know what I went wrong?  

 

Thank you in advance.

 

ps, I haven't try Setup 1.30 since I don't have Paypal account

Hello beonoz

 

Just a thought . Maybe there is power issue.

Under Windows try to undervolt the Rx480 and see if the freezes continues.

I can't get this to run at all. If it possible to enter then Error 43,12 else system crash 1-4 sec after boot (but manage to get 1080p + AMD Xconnect show up)

Im glad i read that you manage to get it work (in FricoRicos Post 

) .

What psu did you use?.Your RX480 it is factory overclocked and it draw way more power than 150 watts.

Did you try to under-volt it and see if it solve stability issues?

I manage to get it work on Windows 10 now thanks to Tech Inferno Fan and FricoRico  for advice :)

 

It because of PCI Express Slot power draw. I use Highpoint RocketStor 6361A that have 2 molex, first one main x16 board and second one x4 Thunderbolt board.

First setup I use 1 Rail to connect both ( I saw this setup before with GeForce ) it give me system shutdown after login Windows (if driver works)

 

Then after some advice about power, I put one rail per board. This give me stability to boot. Anyway with x16 riser (no molex) system crash half way thru benchmark, with direct x16 connect everything work fine.

 

My Rx480 is XFX GTR RX480 Black Edition a bit heavy overclock with 1338 MHz GPU Clock. Only Crimson 16.7.1 work for me, other one give me troubles.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?

      Hi,
      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
       
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

       
      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
       
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
       
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

       
      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
       
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
       
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
       
      1) laptop on table, playing GTA V 1080p

       
      - first minute (GPU core 1045MHz)

       
      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

       
      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
       
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

       
       
      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
       
      Greetings!
       
      I will describe next step when I get all stuff I need!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.
