I need to know how can I overclock DSP. I did search but couldn't find it. Is it mandatory to overclock DSP? 720p videos lags for me. Thank you.[/QUOT Yes the overclock is required depending on the content you are paying back. Ok... to overclock DSP. this had been explained many places, one could easily refer the wiki.but anyway, browse to below path(or your custom file path, i have my custom file there) and edit the profile which you currently use on a daily basis . usr/share/kernel-power-settings you'll find some thing like below # minimum frequency to use MINFREQ=250 # maximum frequency to use MAXFREQ=600 # list of frequency configurations: each "frequency:volt,dsprate" FREQS="0:30,90 125:30,90 250:38,180 500:48,360 550:54,400 600:60,430 700:60,430 750:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520" edit the figures in red to whatever you like (max 600) and save it. run below as root kernel-config load xxxxx now when ever you reach a certain cpu frequency the relevant DSP overclock will also apply. to ensure smooth payback/recording, you can lock the cpu to a certain frequency which will lock the dsp too. eg While watching a 720p movie, kernel-config lock 700 After watching kernel-config unlock ps: i've used the default profile above for explanation purposes only, use your own voltages for your device. hope this helps nkirk
