I'm running a Froyo Sense ROM, CPU is undervolted to 950mv, overclocked to 1.113. I am using full RAM (usually 200-300MB free RAM).
I also tweaked my autokiller ram settings and a few other tweaks. I just did a quadrant benchmark test, I think the results are pretty awesome. This thing is lightning fast. I want to see an Evo bench to compare, so I can try to beat it!
