Just recently upgraded to windows 10, when I set my clocks at 1866 D.O.C.P. or manual my system freezes when I web browse. My memory is rated at DDR3 2000, but the default is DDR3 1333. When set to DDR3 1333 it doesn't freeze when browsing but it freezes when watching videos after a while. i ran Windows Memory Diagnostic Test and CHKDSK in the command prompt and have no issues. Is it possible my RAM is failing me or my Northbridge? I have reinstalled Windows 10 and reflashed my BIOS but I'm still having the same issue.
