Hi All, Don't know if anyone else has this problem. If I OC Asus Strix x 2 to +70gpu and +400mem 3dmark (Dx 11) locks up almost immediately. If I run Time spy with same OC - complete's run approx 12000 3dmarks. Same thing happens if I run a game in Dx 11 or Dx 12 - the Dx 11 will lock, the Dx 12 title runs as smooth as. Any ideas for a fix? Thanks, Nate.
