      In dual monitor config, VRAM always working at 1250 MHz. When it will be fixed? R9 290X.

              This is normal and has always been like this. As soon as you enable a second and or third monitor the memory clock jumps to it's max i.e 1250 for our 290x. With one monitor it will drop to 150 unless you do something graphical oriented.

              Even with my old 5870 and 3870x2 it was the same.

                  It's nice. But its a bug. Nvidia working stable, and similar in one two or three monitor conf. Doesn't heat and consume extra electricity. I want to AMD fix it.

                  My English is far not perfect, will try to say maximum simple. There's another way, every time when it's not needed I can reduce the vram clock in global overdrive. But it's uncomfortably.
