I currently have my Droid overclocked at 900 MHz and it's running quite nicely. My question is what do you all have yours set at and have you noticed any negative side effects? I want to go higher but not too far into dangerous territory.
I found that the Droid will tell you if your pushing to hard. Mine can go to 1.1 and run fine, but anything over that I get bootloop's and heat issues. My wifes can go to 1.25 and run fine, some people have been higher then that but thats seems greedy.
I also have it set to 800 for battery life. Some droids can run higher clock speeds no problem (as mentioned earlier) with low voltage kernels to help keep them cool, that is if you don't mind the battery drain.
I've got a 2800mAh battery on, so I'm not worried about power.
That said, my Droid is running CM7RC4 and ChevyNo1 LV/1GHz kernel 250/1000 on demand. I'm past 100 hours on this charge and headed for 125 or so.
I'm only on wifi, though, not hooked to a network yet. I'll probably jump on next month.
Now I'm running Prime's deprimed kernel at 900mhz. When I first started overclocking, I would set it at 1.2ghz. Later saw it was pointless because my phone didn't like being set that high. Actually made it slower.
If you do try different kernels, I suggest loading a few to the sd. That way if you bootloop your not stuck, just boot to recovery and flash another. This saves time by not flashing a backup. If you do have bootloops, try a different kernel that's either lower in frequency of one with higher voltage.
