anyone get the thunderbolt 2 dual to work on a z97a/usb3.1? can't get it to recognize on windows.
Tubeboggan, I've had the same problem and i've solved, at the end card is working only if i don't reboot but if I shut down mac no problems, card works!!
So,
for get it recognized in windows you have to check these parameters:
Go to...
Boot
Fast Boot = Disabled <<<<<< very important
Thunderbolt
Security Level = 'no security'
Wake from Thunderbolt Devices = 'Off' <<< also very important
AIC Support = 'On'
AIC LOCATION = 4
Thunderbolt PCIe Cache-line Size = '128' <- choose down to 32 if necessary SMI/Notify Support = 'On'
Ignore Thunderbolt Option Rom = 'On'
TBT Device IO resource Support = 'Off'
Reserved Mem per phy slot = '32' or up to '128'
Reserved PMem per phy slot = '32' or up to '128'
Well I've had to play something around with cache size and mem , at the end I've used 128 for every field.
Strange thing at the end in OSX is that audioboard via thunderbolt works but i don't see in sys info thunderball device showed and also it work only if i shut down and boot...no if i reboot. Or, let me explain,when i reboot it works randomly, expecially if i go back into the bios and modificate the mem & cache number.
I've read in other forum that maybe this problem is a reallocating problem?
