I'm right now using Beta chipset drivers for my Ivy Bridge-E and those are the latest chipset drivers from my motherboard's manufacturer's website. The previous ones are official drivers buy they don't recognize my 4820k and I have to use the beta drivers. I checked Intel's website for the latest chipset drivers for their X79 boards but they are very old drivers that don't support Ivy Bridge-E. I'm stuck with beta chipset set drivers unless someone here knows where I can get official chipset drivers that support my CPU. I'm using Windows 7.
