LV vs. ULV kernel?
Just wondering if there is a particular advantage to running the low voltage 1.0GHz kernel over the ultra low voltage, or vice versa? Both of them run quite stably on my phone, but I've read a couple of horror stories about ULV kernels permanently limiting the capacity of some phones' processors to handle various kernels at reasonably cool temperatures :\ Am I just being paranoid? Or am I really safer with the LV over the ULV?
I am using Chevy's kernels because they run cooler than P3's for me. Thanks Chevy!
id say just paranoid - if its stable, run the ULV
From what I understand, ulv uses less battery. Not a ton less, but some. But the lv I believe starts up a bit faster than ulv

The ULV kernels would cause the processor to use less power, therefore increasing battery life and running cooler.
In theory, under-powering a device can be damaging if there is not enough power to switch on the circuit, it can cause "feedback" through other parts of it.
I would say, however, that if your system runs stable on a ULV kernel, than you should be fine to run it. Motorola has built in some pretty good safeguards, so I would think that any potential damage from it would be limited, and quite a few people run the kernels with no issues.
Worst case scenario: You have insurance, right? :)
You would know it if you werent to use an uLV kernel. Some cant even boot with uLV kernel flashed. If you can and things run smooth, then its good for you. I personally use uLV 1.2, no issues to date. Good Luck,
Josh, how long does your battery last?
I can't even run the 800Mhz ULV. The first time I got a random reboot 5 minutes into a sleep timer app. The 2nd time I put one on (newer version) I was lucky to get into ROM Manager and choose a different one, actually I think I had to restore a backup. It was so unstable for me the first time it booted I actually didn't get past unlocking the screen. LV works fine for me though. Like joshk says, if you're not supposed to be using a ULV kernel you'll figure it out pretty quick lol. Guess I got one of the more average chips off the wafer :( I guess it could be worse, at least I'm not stuck on MV (which I believe is actually stock?) kernels.
I had been using 1.25 ulv since the day it came out, it ran super cool and I had battery forever, but more recently I have been trying to stick to the recommended kernels for each ROM. SS 4.6 came with an lv 1.1, i believe, so I just re-flashed a ulv 1.1, and it runs great. I have used anything from 1.25 ulv to 800 mv successfully, so no problems there.
Does P3 make a ulv kernel? His page P3Droid Kernels
seems to only have SV and LV
