I just got my mobile barton and I'm stuck at 12.5X200=2500mhz. If I choose 13 and above, it chooses much lower multipliers for some reason. I have heard of a wire trick or else cutting a bridge on the CPU, but I can't seem to find any info on the internet. Does anyone have a link of how to do this? Thanks! :)
