i have tried to up the voltage a little but it did not work. I have found the problem and it was qouted here already about the epp settings. I found that if I had my ram at the 533 divider ( which is in epp mode) then it would unlock settings for my ram to allow the clocks to go higher but when I set my ram to any other divider(200, 266, 333, 400) then all those extra higher settings would disapear and it would no longer allow me to run my ram at the higher frequencies. I have seached and searched for a way to unlock the epp moder all the time but can not find anything on my motherboard. But thats ok I will be updating to a MSI 890FXA-GD70 around christmas time with either 3 5850 or 2 6870 dont know yet but i am really excited.
