deprekate

Well I ended up using the GTX750ti in my tower. I re-installed a fresh install of Win7 on my laptop (still UEFI). I am trying the ATI HD5670 I pulled out of the tower. I still get the code 12. I have tried hot booting and only turning it on when the windows 4 dots appear. Neither work. Do I need to do the DSDT override again? Or is it just impossible to get ANY eGPU working on a UEFI Windows 7 8460p? (I also have an HD5750 but I am waiting for a 6 pin power cable to arrive in the mail. I don't want to buy a GTX660 and still have the code 12)

I have an HP 8460p, it is dual booting OSX and Win7 (so it is using UEFI). It has 16GB of ram and a PE4L 2.1b. I bought a EVGA GTX750ti, and followed all the steps in the DSDT override, got everything to compile and, loaded into the registry. I can see a new Large Memory entry in device manager (but no other Memory entries, which i think is correct. the guide just has two Intel HD graphics circled in red for some reason). I have tried the fixes, removing Device manager entries/restarting/hot pnp. I still cannnot get the "Code 12" to go away. I was going to try the setup 1.30, but then I saw that it doesn't work for UEFI (although beta might?). 1) So my question is it possible to get the 750ti running on UEFI Win7 with 16GB ram? 2) Or should I eBay the 750ti and pick up a "GTX560Ti, GTX660, GTX660Ti GTX670, GTX760, GTX770", or some other card you recommend? 3) Is there any card/possibly of the eGPU and same card working on my OSX partition?
