Thanks. No worries about that. You gents have a lot to do and imagine if every person in the forum said, "Sorry mate, I don't know." 
I was toying with the idea of lowering clock speed and under-volting
Reflashed my ROM and the O/C Deamon got installed this time. I do not have any games installed on my phone and none of my apps are that intensive (except maybe PicSay Pro and Photo Enhance Pro). I was thinking about running my DHD at Desire Z stock speeds and see it is makes a difference in battery life.
Basically, from 1150 MHz @1075 to 844 MHz @1025. I am sure that if I ran a processor intensive battery test it I would see some difference. But given that I use my phone in many short 5-10 minutes burst, with the display accounting for 40-60% of the use, I might be slowing things down... taking more time doing something and waste more power keeping the display up.

yup... you are exactly right... les is not always better.
if you do want to mess with clock speeds and voltages,may want to make a backup first,and change voltages slowly. dont make any big changes,do it in steps.
some phones can handle more UV than others,and it will let you know when its not happy with crashes and reboots. this is when that backup will come in handy,as the phone may not stay booted long enuff for you to change the voltages back in some cases

Yep, to what Scotty says, my DHD couldn't take anything more than a - 25mV across the board. Any more and it wouldn't boot.
You're best to start off small, test for a bit and once you're happy it's stable, lower again.
There's an app called System Tuner which will do it for you if you're not comfortable with the inbuilt Daemon. It doesn't change the specific system file for UV so if there are issues (it applies the values on a successful boot) and your device reboots constantly, it will restore the default values apparently.
No idea how it works, but I've used it no problem on my One X.

The built in O/C Deamon is pretty basic, no profiles, but I am happy enough with the pair of settings for wake and sleep.
Interesting to note is that since ARHD comes clocked at 1.15 GHz (instead of the 1 GHz default), the developer made a script (?) which you can run from the restore which will bring the phone back to 1 GHz. I am not sure if this changes only the speed of the voltage.
If it just changes the speed, than this will be good if you overclock to high. Run the .zip and it brings down you and you should be able to boot the phone again. If it does not adjust the voltage... might be risky to under-volt.
I was just toying with the idea...
I have gone back and forth between between 1150 MHz @ 1075 vdd and 1000 MHz @ 1050 vdd. The phone seems to lag a bit at the 1000 MHz @ 1050 vdd. Not regularly, but intermittently. Maybe 1050 vdd not enough to run it a 1 GHz?
I am not sure if this is correct but from a thread it appears that the default vdd of the DHD is 1100. If that is the case I am very happy with the 1150 MHz @ 1075. From my PC overclocking days a decade ago, any stable overclock you could get on stock voltage was very very safe.
