Hello, I have E4310 with 16GB ram - works great under Ubuntu but I need to use Windows 7 from time to time and that isn't working. I loaded modified dsdt to extend the root bridge into 36bit space that I found on this forum (http://forum.techinferno.com/diy-e-gpu-projects/7476-%5Bguide%5D-dsdt-override-fix-error-12-a.html) but Windows is freezing on "loading windows" screen when more that 8GB of ram is installed. Any chance that someone could help me to solve this issue? Is it solvable?
