I would like to thank Micutzu for finding this mod, it really seems to help. I am still testing, but I seem to be able to do 245 fsb with 2x256 BH-5 and 240 with 2x512, which is a big improvement. While it is still not enough, this should help me feel better about my AN7. I did the mod with a 25 turn 25K trimmer, which gives me a much higher range of voltages available, but I have not tested above 1.9v because my cooling is not adequate yet. I have a Thermalright NB-1c coming soon that will let me try higher voltages, but for now, I am quite happy.
