hmmm... been using the Gigabyte Z77X-D3H for nearly a year

no problem till now, used to OC my CPU but my Artic Freezer 13 cooler is not build for the OC much so downclock back to normal...

stressing my CPU with Prime95 / 3D Mark 11 for few hours - survive

Intel also stated to run RAM at 1.5V on Ivy Bridge but this one I get the running XMP at 1.65V, also the system run flawless, no problem whatsoever...

can't sure about that rumor
