So I recently rooted my Galaxy Nexus and other than using WidgetLocker I haven't done anything to my phone to take advantage of my root and SU privileges. This is my first phone that I have done this too so this is all a major learning curve which brings me to my question(s): (1) Can the phones memory be over locked? [If yes....] What are the factory Memory Times and what is a safe level to overclock them to - and How? (2) What is the factory setting for the processor and what is a safe and efficient overclocked setting? Is the Highest (but again safe and efficient) level a noticeable change? (3) Overclocking the GPU can reach a maximum setting of 512Mhz (correct?) What is the default setting for the GPU and is overclocking the GPU to the highest (but "safest" & efficient) level noticeable and worth the trouble? (4) How do I overclock my phone? I know that (probably) a kernel replacement is going to be the answer to this question but I was wondering if maybe there is a script I could run in recovery console or terminal, whatever...instead of replacing the entire kernel. If the kernel is the only way, does this effect future ICS system updates? What is the best (most stable, most features, best for overclocking) kernel for ICS/GalaxyNexus? - I dont know poop about kernels. (4a) with the kernel loaded, what apps do I need to snatch from the market to actually overclock my Galaxy Nexus? Try to recommend free ones please =P (5) Since I am replacing the Kernel, should I dive in 100% and flash a ROM too? Yes?: what is the best (very very stable, fast, efficient, tweakable) ROM out there for GNexus? do roms do anything to assist in the overclocking process? The only reason I would consider a ROM too is because I want Wifi/USB Tethering, Facebook contact syncing, and a few other things.. but only if there are overclocking tools too! Does flashing a ROM eliminate myself from ICS updates(pretty sure the answer is yes)?? (6) I am currently on a stock kernel and "rom" (if u couldn't tell...) but I am rooted and using Launcher Pro (free version) and I am happy with it but out of the other launchers which is the best (fastest, easy to use, customisable)? If I flash a custom ROM will a custom launcher be necessary or do they cone with tweaked launchers? I had other questions but I can't think of it right now, I'll update the OP and thread if I think of anymore. Thank you so much community members for taking time to answer these questions!!!
