Hey happy new year...
My system specs are 3930k, xfx 7970, corsair ax1200, force Gt
but good news everything works once more... turns our my first Dimm port stopped working and as soon as I filled up another red Dim port it worked fine booted to the bios (4.1 I think, the latest one because when I had problems earlier I flashed the latest bios). I rearlly don't understand because now everything works again and it is in the same config as it was before. I am guessing the bios was the problem but I am probably going to RMA the board because of the dim switch+ I had noticed earlier as well that it only saw 3 of my 4 sticks.
Cheers
