AMD K10 Architecture - technical explanation by InsideHW

how much voltage should be put in HTT? Mine is on 'Auto' right now because i dont want mess with it.

shouldn't need to increase the HTT voltage much if at all
I only increased HTT voltage on my 6000+ by about 0.1-0.2V to lower the difference between it and core voltage (when I was pushing 1.6-1.7V vcore)
