Ok thats good news. So Next step? Get rid of that riser and enjoy your egpu

Im glad i read that you manage to get it work (in FricoRicos Post ) . What psu did you use?.Your RX480 it is factory overclocked and it draw way more power than 150 watts. Did you try to under-volt it and see if it solve stability issues?

Hello beonoz Just a thought . Maybe there is power issue. Under Windows try to undervolt the Rx480 and see if the freezes continues.

Hello FricoRico and goalque Im going to build an egpu (akitio thunder2 + rx480 + dell 220w ps) for my late 2011 imac (i5 2400s) My imac has the thunderbolt1 port and discrete gpu 6750M .I believe thunderbolt 1 will be good enough because rx480 performs well in low bandwidth. I saw scores from EXP GDC setup and if that scores are true the performance is around 85% of desktop performance. Just a silly question because im lost in this part. Did you manage to get internal screen to work or only works on extrenal display? I will use under windows 10 + sierra when apple officially release it. Thanks

I will do that steps but My thought is if HD2000 is supported with optimus switching gpu

hello Is this possible also with HD2000? if i can enable intel HD 2000 maybe i can run eGPU (GTX970) in imac's internal monitor/ All i need is to disable amd 6750m and enable intel HD 2000 for optimus . Thanks Mike

Thanks for your reply, my imac under windows has iGPU, The intel HD 2000. On osx intel hd2000 it is not suppoorted. So that is the reason i believe external gpu may be possible in internal monitor.

Please i cant find any information for imac, only for rmbp. Do i have to drob this project or is possible?

Dear all Im somehow lost but i start to figure out what happening. I have 2011 imac i5 2400s and amd 6750m and TB 1 . Is possible the egpu thru TB? Do i need external monitor or i can use imac's internal monitor? im planning to build GTX970 egpu but i had to know if is possible for my imac. Thanks Edit: The egpu is for bootcamp and windows 8.1 only, i dont plan to have egpu on OSX Sorry for my english
