I'm having a weird RAM issue with my Kingston hyperX blue memory I have 4x2gb of it. It is supposed to be as fast as 1600mhz, but at BIOS it is 1333mhz.
I have tried to change it to 1600mhz with 1.65V but i can't get it to boot with those settings.
I also have overclocked my CPU @ 3.8 ghz, though I don't this has anything to do with it.
Here is CPU-Z validation http://valid.canardpc.com/2886841
