One good test to those who want to see visible OC changes, is to install ENNA (like a media center for those who dont know..i think lol). Booting speed; Gallery Scrooling..Wow, what a difference between the 600 Mhz and 900 Mhz. Still thinking to test the 900 Mhz with 500 DSP..but there are no much comments about it..i'm afraiiddddddd ahahahaha : ) Regards,
