I did more testing with 5 different memory brand/models, filling only slot 2, and slot 2+4, this time. G.Skill and OCZ, DDR-1066, 1333, 1600, 2GB, 4GB, 8GB sticks. None of them resulted in integrated graphics being available.

I understand that not all memory are compatible with all boards, but I find it hard to believe none of my 5 sets can make IGP appear, or usable beyond 2 DIMMs.
I just starting to have the same behavior with my Extreme 4 after re applying thermal paste to my CPU. How did you fix your problem with ram and integrated graphics
