well i got up to 1.4 (140x10), but when i try 10.5x133 windows wont load. tried 1.8V, though its on a A7A266, so i dont know if thats really 1.8V or 1.89. I still am relatively new to all this so if anyone has any ideas let me know. also, how much voltage is too much for a t-bird? heh, right now, since the multiplier is a pain to change on this board, im running 10.5x100, 1050.
