Is anyone having trouble getting keeping the system stable running using F4-4000C19D-16GTZ Gskill dual channel RAM using the XMP profile 1 settings of Timing 19-21-21-41, it shows on the QVL for this board as being able to run at rated speeds but I was getting BSODs or Overwatch crashes if I kept it at that speed, had to drop back to 2133mhz to keep system stable. Memtest showed no errors, and all drivers in device manager were updated manually going thru each device.
