Just wanted to say thanks for this guide! I just got a 7950 in the mail today and within a couple of hours I managed to go from about 140 Kh/s to a solid 600 Kh/s and only 66 degrees (fan at 56 percent).  I know I have more room to play right now but I am at 0.962 v, 1000 Mhz core clock and mem at 1250 with an I=18.  No hardware errors.  Very pleased and I know this saved me a TON of time! 

Now, does anyone know where I can attend a crypto-anonymous meeting, I think drugs are less addicting...
