Nice system - just did the pencil unlock on my bro's duron 600, easier than I thought it would be. Those bridges look small, but you'd be surprised how easy it is to draw a blob on each one without crossing over. I had a few goes at it cos I went straight for the higher multipliers (8.5x, 9x) and upped the voltage to like 1.7, 1.75. It didn't post, so i assumed it was the bridges - turned out the voltage needed to be 1.8V. Have fun ocing that GeForce2MX if you're willing to risk it. Mine came with NO cooling on the gpu, still went from 175/275 to 210/310 np. Slammed a blue orb on there, got to 220/310 (can't go any higher with coolbits reg edit). Got me about 600 extra 3dmark points. Have a look at the beginner's articles on the front page if you haven't already, they helped me a lot. Hope you get your gig!
