Hi, I have a problem with my eGPU, I cant get rid of Code 12. I have the following stuff: Acer 5750G (2630QM, 540m (deactivated in BIOS), HD 3000, 8GB RAM) (There seem to be several people who use an eGPU with this notebook, so it should work somehow) 650W PSU EXP GDC 8 mpcie Gigabyte GTX 960 4GB I did the DSDT override and the device manager shows me the large memory, but it doesn't use it. I also tried the pci compaction in Setup 1.3 and set it to 36-Bit and followed different instructions I found on the web, but Code 12 stays. Even if I try to only get the iGPU in 36-Bit space, it doesn't work. Could my DSDT Override have been faulty somehow? Even if it shows the large memory section in the device manager? If you have any idead, please write! Thanks in advance EDIT: Can you do a PCI Compaction 36 Bit without a DSDT override? In that case I'd try.
