Hi All, So I lashed out and bought a new gtx 1070 to replace my gtx560 Ti (What can I say, medium quality and 30fps most of time in fallout 4 is enough). My z77 chipset mobo and i5-3750 has been flawless and does everything I need it to so - its bene chugging along nicely for 4 odd years now. When I removed the old 560 plugged the new GTX1070 in the damn machine won't post. I stood there with a finger in my ear for a few minutes adn noticed that the mobo has a DIMM LED that would come in. First thing I did was pull one stick from the dual channel arrangement and what do you know the video card works, machine posts and boots (60 fps at ultra quality is NICE). Anyone have any suggestion ? Putting the 560 back in with both sticks of RAM does not present the same problem. I suppose I could flash the bi or something.
