Hello my friend how long have you had your system?
The reason I ask is that sometimes hardware starts to get tired especially if you overclock the hardware. So as time passes you have to change some settings to make sure your system stays at that overclock. That is what I think you have to do.
Change some of your voltages just a little higher and see if that helps.
It could just be your ram that needs to be looked at. I would run memtest (download ver 4.2 for the usb stick) and check to see if they are good.
Thank you for the kind words about ROG forum.
