Make sure you are cooling the NB properly though otherwise pumping volts into it could cause more instability than stability. I still really, really strongly encourage you to put the CPU overclock through the stress tests I identified. You need to make sure you are absolutely stable in terms of CPU, DRAM, and Uncore before you start searching for answers in pumping more volts to components.

believe me I am following your advice. Here is my current setup which has passed Prime95(8 hours), and Linx (25+ passes x 2)

Do you see anything that I could possibly tweak to get some higher BCLK with it?(forget the Crossfire issue right now)..I noticed a lot of my settings for voltages are currently set to Auto...perhaps I can benefit from some of these beings raised? I have read a lot of threads, but this seems the best place for me seeing as these settings have to do with the R2E MB...any advice is appreciated:
