Your hatred for realtek is unfounded - this is almost certainly an overclock issue. What volts?
Do 5 loops of IBT at max memory and post a screenie.
As per the information you have provided your issue is with the Realtech driver Rt64win7.sys. Go to your motherboard's website, find your motherboard and update to the latest onboard audio drivers.
It's been 3 days and no BSOD, thank you for your help!
Unfounded how so?, do a google search anyone that has had that BSOD is told to update the driver. I've done just now as the driver was a year old which was the latest from the gigabyte website!. Gigabyte are well behind.
