I did this along w/ a reset so that I could undervolt as well....followed by a reset of course. Should I try to do it again?
Thank you for the quick reply.

Does your rom have LeanKernel file in System/etc/init.d/
Try downloading/updating your Busy box from the Play Store.

Hmm....That I'm not sure of. I'll go and check and get back w/ yall as soon as I can!
Ok, so i checked the int folder and it does have "00leanKernel" inside says:
Code:
#!/system/bin/sh
VMIN=0
echo $VMIN > /sys/devices/system/cpu/cpu0/cpufreq/override_vmin
As for busybox....I"m not sure if that is on this ROM or not. If not should I install it? I found a BusyBox app on the play store that says its supposed to install busy box. Jus don't wanna mess up anything lol.

I did that, Normal Install. Reset. Atm it still looks like its hopping around. Generally staying at 1512 but also going as low as 1134 like before. Govenor/ ondemand, scheduler/row
Maybe the kernel still hasn't settled yet? I've had it installed for the last several days.

Aight, which kernel app are you using? It should only act somewhat iffy for about ten minutes after the initial kernel flash not a couple days. Also, is the phone hot while you're trying to adjust the OC?

I'm using SetCPU. Min set to 384. Right I would've thought it would've settled by now. Generally really w/ most kernels I've installed they've all had a tendency to jump up in heat kinda quickly. So yes it does generally get hot even while adjusting OC.
Yea, maintaining OC can be somewhat tricky depending on the heat produced. Does this continue to occur when you select "set at boot" option for the CPU?

If you're using the free version of Tegrak, your settings will not stick when you reboot. You have to have to the paid version to be able to "set on boot."

Wrong. On Imoseyon's kernel there's a command you can use to permanently use Smartass on startup. Look around for it in the thread. That, or you can modify the starting script for the kernel, but I have no idea where it's located.

Uhh I'm not wrong. To begin with, he was asking about the APP, in which I said "the app won't keep the settings if he's using the free version." THEN when he asked if there was anything he could do to the KERNEL, I said I didn't know.
My device is incompatible with this rom when I try and download emulator.

Ok, went back and read the OP. Still the same conclusion. He was asking about the app. I told him you can't do it with the APP. Therefore I answered his question. When he asked, "is there anything I can do with the kernel?" I said "I don't know."
Once again, I was NOT wrong. You can argue your point all you want but I'm done arguing with you.

I'm on Trickdroid v7.0.0 which should have the latest busybox. Are you saying I should install the newest busybox from market?
Can anyone confirm if this has a smart script that turns off CPU1 and underclocks both CPUs when screen is off?

No the latest is 2.0 something, use the 1.19.3 version because the latest doesn't have start-stop-daemon included.

Yes it puts it to the lowest state when screen is off by default, unless you change the profile off and set both min max high it will always knock it down.

No it does not, when using ondemand governor it adjusts the cpus when necessary. When cpu1 is needed it comes online, kinda makes the cpu1 off while sleeping unnecessary. I am thinking about adding the underclocking while the screen is off and while the phone is in use for a future releases. But this script doesnt use screen off to do anything.

It could be that you need to do a factory reset on your phone and start fresh, that could probably fix your freezing problem.
Also you might also want to look into updating your phone to LG's official 2.3.4 ROM, it is much more stable than the 2.3.3 ROM that your on.

I've gone so far as to completely wipe the 'sdcard' and start from scratch. Running 'lsmod' in terminal shows that the module is loaded, and the max speed I select shows under cpu in venom tweaks. This is driving me nuts! What can I do to troubleshoot?
When you flashed elemental, what did you set as your max CPU speed?
What program are you using to check / set CPU speed?

I've tried 1728, 1809, & 1890. I even tried speeds lower than stock, and it still runs at factory speeds, so I'm thinking something is wrong with the oc module, but I don't know his to check. I tried using the app built into viper, setcpu, and kernel tuner. I thought they may be conflicting, and that's why I wiped and started fresh.

For the first custom ROM for the Discover go here http://forum.xda-developers.com/showthread.php?t=2673097
These are stock ROM's for the Samsung Disover SGH-S730M. The will work on the S730G also. I have uploaded these so you can either return to stock or use as a base for your custom development. If you use for custom, please give a mention or a thanks as it took hours upon hours to bring the first flashable ROM to this phone.
Option 1 is bone stock, no root, no busy box, no over clock. After flashing this option CWM will ask you if you want to fix root before you reboot from recovery. Select no. If you want root, download option 2 or 3.
Option 2 is stock, with root and busy box added.
Option 3 is stock, with root, busybox and overclocked to 1000mhz
No other changes have been made.
I have flashed and test all three to verify they are flashing and working properly
Option 1 Download: http://d-h.st/S2R
Option 2 Download: http://d-h.st/cI9
Option 3 Download: http://d-h.st/5FZ
Installation:
1. Wipe data/factory reset
2. Flash
3. Wipe Dalvik
4. Reboot
Enjoy!
Waaoooo!, i download, try and come back you, great job
Edit: Install download Option 2, work

In the download option 3 you have set kernel with clock at 1000mhz, and he start at 122mhz too ? or it's 245mhz ?
I used option 2 with NoFrillsCPU for setting cpu at 122mhz. I listen music without problem with bluetooth too.
This rom is stable and no problem with battery. Again great job
Minimum is set at 122 max is 1000. It usually runs between 480 and 600, only boosts up to 800-1000 when needed. It's safe to run option 3, and use nofrills, cpu tuner, set cpu etc, and set the max to 800, then if your playing a game or watching you tube, and find your lagging a bit you at least have the option to bump it up to 1000. Then just set it back when your done. That's how I run it

The only thing I have found is flashing the "M" to the "G" you have to manually transfer the apn data after the flash. Or you can't send or recieve mms messages. Other than that no problems.

Ya that's completely to be expected, the M is from Canada, so it has different carrier APN settings. Easy fix. Just google your carriers APN settings and punch them in
