Hi, I'd like to use the Cooler Master Elite 130 case to build an eGPU. I would not like to use the paper clip trick in order to run it, but rather use the enclosure's original push button to power it on. To be more precise: A short press on the front panel power button should permanently connect PS_ON to GND. My idea would be to use a relay module to connect PS_ON to GND using the 5V standby current. Would that work or is there any other solutions for that? I saw other people recommending the swex atx but I haven't found any sources of information whether the desired push button behaviour would work; moreover, the swex atx seems not so easily available, found none on amazon/ebay. Switching off would be done then over the Akitio Thunder2 and the Mac Mini attached to the whole thing. Thank you in advance for any hints! Michael

I've got it resolved - I've had to provide AMDSupport.kext, AMDRadeonX3000.kext and AMD5000Controller.kext with an "IOPCITunnelCompatible" Key on <true/> and very important (THAT WAS THE MISSING BRICK) .... I've had to do a "touch /System/Library/Extensions" in order to rebuild the kext cache. Everything is working fine. 6 Monitors, each running smoothly, playing HD videos fluently.

Hi, I'm trying to get an egpu setup running and I've already tried with the BEAST v8.4d EXP GDC but that turned out to be too slow. Soon I realized: ExpressCard is my bottle neck. So I had to come to the following setup: 6 x Dell U2417H Monitor (DP-input, Mini-DP-input, HDMI-input) Akitio Thunder2 PCIe Box Gigabyte ATI HD5870 Eyefinity x6 with 6x MiniDP-output 600W-PSU Mac Mini late 2014 With the Akitio, I had to take out the board in order to fit the card into the slot. The Card is being recognized by El Capitan immediately, the 6 monitors are showing a picutre, I can arrange the monitors. All fine. Not. Because: The speed is not fine. Even with simple operations like moving around a window, it's slow as hell. It seems that there is no acceleration active. How can I find out which is the missing brick to the full solution? Is the Akitio Box the bottle neck and the whole thing is condemned to not work? Or do I have to check the drivers under Macos? Where can I look next? I've already looked to see whether the relevant kexts are loaded, maybe this helps you providing me with the right hint. bash-3.2# kextstat |grep AMD 138 2 0xffffff7f82d84000 0x125000 0x125000 com.apple.kext.AMDSupport (1.4.2) FF769178-12FD-3CB4-BBD7-B2FA5A99C45C <88 86 12 11 7 5 4 3 1> 139 0 0xffffff7f82ea9000 0x5f1000 0x5f1000 com.apple.kext.AMD5000Controller (1.4.2) 1CE0058A-3411-3A16-9CEB-410D96963BC2 <138 86 12 11 5 4 3 1> 147 0 0xffffff7f834fa000 0x22000 0x22000 com.apple.kext.AMDFramebuffer (1.4.2) 8BC41ECB-68F3-3579-9D12-5D03AA7BBEA0 <138 86 12 11 7 5 4 3 1> bash-3.2# find /System/Library/Extensions/AMD* -type f -exec grep -H 0x68981002 {} \; /System/Library/Extensions/AMD5000Controller.kext/Contents/Info.plist: <string>0x68981002 0x68991002 0x68E01002 0x68E11002 0x68D81002 0x68C01002 0x68C11002 0x68D91002 0x68B81002 0x68B01002 0x68B11002 0x68A01002 0x68A11002 </string> /System/Library/Extensions/AMDRadeonX3000.kext/Contents/Info.plist: <string>0x68981002 0x68991002</string> Maybe a screenshot of the Graphics Adapter in the system information helps you / see uploaded image. Any help would be appreciated. Kind regards
