Very nice overclock on that 1600+

That's the board my friend wants to buy, I'm gonna send him a link to this thread. Are you using all 3 power connectors? Is that 4pin connector for boosting the RAM voltage? I gotta say I liked my AK31A when I had it and thought it was a great budget overclockers board, it looks like Shuttle is continuing to improve their enthusiast's boards.
EDIT: Harkwave.com is your site I take it?
