DroidX: Tranquility 3.6.0 with DarkSlide Theme and Overclocked at boot 1225 no problems!!
Not bad i guess, if you wanna compare quadrant scores (which really arent that important) my X usually hits 1750-1850, give or take. Havent ran tests on other stuff. I prefer the "seat of pants" feel....if it runs fast in my hands Im good.

Sure the scores have meaning; and as to yours, unless that DX you have is one of the very few, you may overclock it at 1450 but it wont run without reboting. Nevertheless, if it does, my hats off to you. My phone stays on until I repower it. This Rom seem fine to me and I've yet to find something not working. Will I keep this Rom? Might, might not, I change Roms about once a week.
Ps. Be true to ANDROID and toss that apple!!!!!
