I need a link to a tutorial for the Epic. I want to learn about how to manage the relationship between the two. It appears that my phone is capable, has the correct kernel but I don't know how to do it safely and correctly. I will use the Tegrak app when I learn what to do...
Overclocking and Undervolting

In short, a higher clock speed can require more electricity. More power = More Powerful = Faster
Lower voltages can cause instability at higher speeds, but can be used at lower speeds (such as at idle), resulting in a pretty aggressive power savings when the phone isn't taxed or idle.
Every processor has different tolerances to non-standard voltages and clock speeds. Your mileage may vary, just because my Epic is stable at 1.5ghz (sadly it really isn't...), doesn't mean that yours will be.
Increasing power will also increase heat, which can decrease the lifespan of your phone. Take it one step at a time, use the phone for a day or so, than step it up a little more until you eventually find the highest level (hanging, locking, odd behavior), than dial it down a couple from there. In my humble opinion a 1.2ghz clock speed at standard voltage is more than enough to give the phone some oomph.
For the undervolting at lower frequencies, same thing, do it a bit at a time, and dial it up a bit if you get to a point that it won't wake up, or locks up at idle or non-processor intensive tasks.

I hate to tease but at 100/800 Mhz with the Lazy governor (not offered on the Epic) I can pull 24+hrs of battery and pull Quadrant scores in the low to mid 3000.... LOL....
Punch that baby up to 1.4 Ghz and I can pull in the mid 4000 scores....
I know... I'm teasing... Me and my Nexus S4g....

Does Tegrak work? I tried to reset the freq but it tells me I need to use the paid version. Do I? Am I doing something wrong? An whats the diff between core voltage and internal voltage?

Hey, I got a solution to ur hate mail. I'll switch my Epic for ur Nexus S4G.

You know I wouldn't even mind really... I never had any real issues with my Epic... I know the ROMs, I know what works and what doesn't and if something didn't play up to my expectations I would just modify stuff by mixing mods and stuff together to get what I wanted.Hey, I got a solution to ur hate mail. I'll switch my Epic for ur Nexus S4G.
Hence, that is where ACE ROM came in back some time ago...
The Epic is a very capable device and if treated correctly it will treat you good in return.
so I bumped it up to 1100 and my q bench sliced in half. What on the trgrak app was I sposed to Adjust? It's still a little spooky for me.
I'm just using the voltage control app that came on the rom. I have the Mhz set at 1200 set on on demand. lowered all the voltage settings below 900 mhz threshhold reducing the voltage a little more as I went down the lower thresholds. So far very stable and fast. 2400 + on the quadrant benchmark

Which rom are you running Keith? I am on ACSICS v5.The app that came with it is Voltage Control Lite- no ability to change voltage settings. I am still wonky on the relationship between threshold, voltage etc. Where can I learn more about it - don't want to brick.
Same rom as you ACS ICS v5. The voltage lite does allow you to change voltage setting. Look for the voltage tab near the top of the screen or swype right to left to change screen. I like this program as it goes back to your original settings when your phone crashes and you reboot. So until you have a good stable setup you are safe. Once you have a stable setup, you can hit the settings button and choose to "save as boot settings" only then will it not reset back to stock settings on reboot. So play with it all you want as it will always go back to stock when you boot. Even when you save the setting at boot, you can always recover your original settings through the flashable zip file you can install through cwm.

I know Quadrant Benchmarks aren't everything, but I am happy to say that I am tying a stock Galaxy SII in Quadrant with a score of close to 3500
I am running Samurai Kernel 1.0.4 (came with SleeperROM) and using SetCPU with scaling of ondemand with a max of 1200.
I switch scaling to conservative most of the time to increase battery life which drops Quadrant into the 2500 range

Haha. That's just mean, Paul. If I didn't love ACE ROM so much and respect you so much for making it, I'd def have some harsher words for you!
Even with GB, I'm not pulling anything near those scores

You have some competition. My Epic 4G simply flies at 1.5 Ghz with a optimized rom

Hey paul what do you think I could pull with my nexus running trinity at 1.54? Lol maybe I should see if I can fry an egg?
