Has anyone tried the FirePro W9100 in a classic Mac Pro (5,1)? Does it work, is it spiffy fast?
But as I mentioned, you can answer the question yourself in about 30 seconds by looking in your system folder.
Sorry I searched here, but the search didn't bring it up. Anyway, it seems this exists:
System ▸ Library ▸ Extensions ▸ AMD9000Controller.kext
So I'll take that as a "yes, it will work"...? Thanks
No, right click on the kext and Show Package Contents.
Contents -> Info.plist, search for IOPCIMatch and see if the Device ID is in <string> list.
<string>AMD9000Controller</string>
<key>IOPCIMatch</key>
<string>0x69201002 0x69211002 0x69381002 0x69391002</string>
those are device ids, I think you are in wrong controller
so, 6920 is device and 1002 is vendor (AMD)
9100 is 67a0
R9 290X is 67b0
try 8000 and 7000
<string>AMD8000Controller</string>
<key>IOPCIMatch</key>
<string>0x45001002 0x46001002 0x66401002 0x66411002 0x66461002 0x66501002 0x66511002 0x665C1002 0x665D1002 0x67B01002</string>
