請教：mLink R外接顯卡的選擇

[afei]

看了這兩個mLink Thunderbolt外接盒實測報告：

現在產品比較多了，還有mLink R和mLink X這兩個產品：

有點搞不清楚mLink R和mLink X這兩個產品差異在哪裡，看資料都是可以裝PCI-E2.0，

現在想請教的是，mac Mini以mLink R外接顯卡，相容mac Mini有哪些選項？
在Apple Store找不到單賣顯卡頁面，不知藏到哪裡了？

問了官方網站，
原來「mLink R是給RED ROCKET專用的型號，mLink X則是通用型」！

還是要看個官方網站介紹才能詳細了解

01那邊有網友提示「Sonnet 」
找到2012年
「2. NVidia Quadro 4000 & Adobe Premiere CS6 - Thunderbolt Testing - Sonnet XMac Mini Server」這個影片：
看來當時那樣做，是為了MacMini的輕巧，
但是又為了補足顯示卡和儲存設備的不足，所以用Thunderbolt外接NVidia Quadro 4000和硬碟。

NVidia Quadro 4000應該是為了可以輔助render Adobe Premiere CS6 （影片是在show這個能力）

影片顯示是在mac OS下，這樣看來OS X可以自動抓到NVidia Quadro 4000驅動。

自己記錄一下，

剛剛在AKITIO臉書粉絲頁，看到這影片：

有人裝成功了！！
「AkiTio Thunder2 with Mac Mini 2012 OS X (10.9.4) + EVGA GeForce GTX 760」

用得是比較便宜的kiTio Thunder2Box：

不過，很好奇，
EVGA GeForce GTX 760很吃電，AkiTio Thunder2Box的供電足夠嗎？

[afei]

沒有想到thunder2box，是用Thunderbolt 2，
售價還比只支援thunderbolt 的mlink x便宜。

那個改裝者將資料PO在討論區：

以下是原作者po的步驟：

[NOTE] This an UPDATED GUIDE currently only works with OS X 10.9.4 version.

HARDWARE CONFIGURATION


Apple Mac Mini 2012 16GB with Intel HD 4000
AKiTiO Thunder2 PCIe Box


Corsair CX750 M
EVGA GeForce GTX 770 4GB
2x Thunderbolt Cable
HDMI
SWEX
Monitor (ASUS VG248QE / Apple Thunderbolt Display)


PREPARATION

Step 1 (Note: eGPU setup should be all disconnected)

Download and Install CUDA driver http://tinyurl.com/dxzoaww


Step 2

Download and install a modded NVIDIA Web driver
Usually, NVIDIA's official Web driver will do a system check. Official web driver can only be installed on MacPro 2008, 2009, 2010. If you are using a iMac or Mac Mini or MacBook Pro, you can't even install. But Modified Web driver avoids the system check. Modded Web driver file name is ModdedWebDriver-334.01.02f02.pkg.
File mirror: https://app.box.com/s/wa2tblhb4y5dtd3fgh1z


Step 3

Modify the following KEXT files from your Terminal and look for sections beginning with CFBundleIdentifier and add just before , the two following lines

kext.png
KEXT Files
/System/Library/Extensions/NVDAStartup.kext
/System/Library/Extensions/IONDRVSupport.kext
/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAController.kext




Every time you upgrade your OS you need to modify these KEXT files
Finally, clear the cache by issuing the following commandsudo kextcache -system-caches and shutdown your OS.
Warning: The following procedure at your own risk. Please be sure to take a backup in case of emergency.


Step 4 (Setup and connect your eGPU. I am using EVGA GeForce GTX 770 4GB Classified)

In my case, I have the following setup;
GPU card is connected to AkiTio PCI-e slot without the PCIe riser. AkiTio is powered by its supplied power adaptor
GPU card is powered with PSU thru its two 8 pins
Connect your AkiTio and Mini using Thunderbolt Cable
Connect your GPU and Monitor using DVI, Display Port or HDMI cable
BONUS: I have an existing Apple ThunderBolt Display, I was able to mirror my display. I connected my TB display to the extra TB port on AkiTio



A BIG Thank you to the following

Results

I no longer experience the kernel panic in my previous setup. I am not sure if its with the GPU card that I previously used (760). It appears that this time this is stable compared from my previous setup using PCI-e riser.

看起來還改了KNEXT!

硬體清單有一個「SWEX」，
不知道是不是這個？？




另外，EVGA這個盒子不知道什麼用途？？好像是把power裝進去？？
