I bought a new motherboard recently because my old one broke down.
I'm running Windows 7 Home Premium 64-bit, and with my old motherboard I was able to use all 4 GB's of RAM. When I switched to the new motherboard I could only use 3,25 GB RAM. I went in to Bios and enabled the Memory hole remapping -setting, but then the graphic card driver won't work, and it seems like the graphic card uses both its own memory (512 mb) and shared memory. If I go back in to Bios and disable Memory hole remapping I can only use 3,25 GB again, but the graphic card driver works instead. Is there any way to use all 4 Gb's of ram and get the graphic card driver to work again?
