2012 Mac Mini + RX480@10Gbps-TB1 (Highpoint RockerStor 6361A) + Win10 [boeonoz]

Recommended Posts

Before start I have to thanks Tech Inferno Fan and FricoRico  for advice, I almost give up and put Rx480 into the box for sales.


Here! I better tell you about issue of my current setup as I know some of you planning to get eGPU, so you won't have to headache later on. I will post what I remember first and add up later.


This setup are not running with DIY eGPU Setup 1.30 since I have no PayPal account, if you want me to try then please get 1 license from Tech Inferno Fan for me.


Issue - Windows side

- First avoid running Windows 10 1607 Anniversary update (Continue Below)

- Currently can't find a way for iGPU to run (Error 45 - Not Connect) / This can be problem when you try Boot option since eGPU will operate after Windows Load.

- New driver not working after 16.8.3 (Series 16) / 10.9-10.10 (Series 21) will show error 43

- Beware of power issue of PCI Express slot draw. For power use 1 Rail per board molex else Rx480 will not operate and keep restart after Login Windows 10

- Riser will not work with high load (Not sure of Themaltake P5 Riser)

- Driver still buggy (You may face Error 12, 43, 31 during setup up to what you choose)


Issue - Mac side

- Only work with macOS Sierra

- With 10.12, Every time you boot have to unplug HDMI/DisplayPort else will result in Boot Freeze (But got Metal running)

- With 10.12.1 Beta4 Can boot with display on but Metal is not on (In testing)


My system

Mac mini 2012 with i7 3615QM - 16GB RAM - Thunderbolt 1

Highpoint RocketStor 6361A - TB2 x16 Case

XFX GTR Rx480 Black Edition

Seasonic X-650 Power Supply

Cooler Master Elite 130


Before I start all this I test my system with ATI HD5850 first, everything smooth plug and play experience.

Compare with my old desktop (i5-750)

I test most system with FF XIV Heavensward Benchmark since I have it on my nas and easy to test.

With this I confidence that Rx480 will be working 100%, so I go with AMD... hah nightmare.

Start with Rx480 on Windows 10 BOOTCAMP (MBR)


About Windows 10 1511 and 1607

As issue said, for RX480 Driver that can be use with eGPU is Windows default 16.6 to 16.8.3 (old series) with new series 16.9+ will result in error 43.

AND!! AMD old driver are no go with Windows 10 1607 - This will result in system freeze with gibberish black greenish screen during game play, AFAIK Overwatch is not playable. Anyway benchmark can be fully run on 1607 without problem.

But Windows 10 1511 also have some issue with Driver installation and stability, for me I cannot get Compatibility Mode show up in 1511 but 1607 is fine. (When compatibility mode on I seem to get about 3%-5% boost over normal in static benchmark)


Ok, let's start.


My setup run with Normal Bootcamp with 2nd drive kit of macmini

Boot with eGPU off if you have multi monitor connect over HDMI port else Intel HD won't get driver install

1. Install Windows 10 1511

2. Install Bootcamp driver

3. Turn off and power on eGPU then Boot


Then this will have 2 option, second one have about 50% chance that it will work.

4a. Install Crimson 16.9+ (It will result in error 43 but don't mention it) go for 5a

4b. Install Crimson 16.8.3 (This is the best one that work during 1st installation, but if it not then Black Screen) go for 5b


5a. If you go for 4a then do DSDT Override now (search for it).

6a. Install driver by extract AMD 10.8.3 and go with Update driver select "Let me choose" browse /Packages/Drivers/Display/WT6A_INF/C0306357.inf and select Rx480

You will have a driver without Vulkan API Install but able to run benchmark and games. or you can try install normal way thru AMD Setup, if lucky and install went smooth you will have fully operate driver with Vulkan and compatibility mode but I mostly end up with GPU fan whirl and freeze.

***Extra*** You can try use AMD Cleaner at this step and don't restart then install Crimson 16.8.3 Setup, if success you will have full driver with compatibility mode.



5b if you able to complete driver installation (XConnect running) then do DSDT Override (or skip but I run in some problem when in games) But if you get black screen go 6c.

6b Just Restart and everything will work fine. You have optimal install experience, but iGPU still no way to work.

6c You can use AMD Cleaner and go retry with 4a. and follow 4a route.

LuxMark 3

I got some issue during writing this article, fan spin 100% without doing anything and still spinning.


Mac side - macOS Sierra


Require monitor connect with iGPU

unplug/turn off eGPU

1. Boot into macOS Recovery

2. Disable SIP (search "Rx480 Sierra" and you will get all How-to)

3. Edit AMDRadeonX4000.kext (/System/Library/Extensions) info.plist (copy and edit other place) add 0x67DF1002 after/before 0x67EF1002

4. Run kext Utility to repair permission

turn on eGPU

5. Run goalque's automate eGPU script via terminal

6. Set goalque's script in -a mode


Anyway I still can't find a way to boot with hdmi/display port plug-in without freeze in 10.12


Hardware Setup


CoolerMaster Elite 130 is totally for Highpoint RocketStor 6361A


For power use 1 Rail per board molex else Rx480 will not operate and keep restart after Login Windows 10, we are not using GTX. This cause me a few day to find issue and fix since I saw other people use 1 rail to power both molex (This is thanks to Tech Inferno Fan and FricoRico)


I can fit anything without drilling any hole. Btw I use 2x120mm Noise Blocker PL-1 fan by mounting 120mm in side HDD bay since we didn't need any extra drive. (I remove CM fan out since it is so loud)



For board mount I use upside down 4 female HEX M3, 2x6mm and 2x8mm since the bottom panel is level. (I don't drill just use for support since I will loce GPU card anyway)



Mount TB board and GPU, there some trick to bring silver back plate there but it is not hard... just try it.







For my setup there is no soldered or drill any hole to case. I feel safer with this.


EDIT: 26/10/2016 Add extra picture of 3 pin -> 2 pin FAN Cable Now my fan start stop with system. (it just arrived from China)

More pics here.


This is what will happen when playing Overwatch with Windows 10 1607 Crimson 16.8.3



This is also happen sometimes ... I have to re-install driver to fix (GPU Core running at MAX 1338 and not back to 300MHz idle) / This one I mange to install driver 16.8.3 without issue, so I don't have to modified DSDT but anyway I still do it later on for stability). But GPU is not really run at 100% as you can see in Process Explorer, only core max but anyway consume high power and hot.

Normal should be like this

      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?

      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.
      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.
