Why isn't it specified? Did you create that profile?
I'm actually not 100% what happens if they are not specified.
But I think it just means it will not be used even if you specify beyond the limites.
Like if you specify 1500Mhz, it just won't go that high.
or it may not idle at 0Mhz so you are going to be hit in terms of power saving.
Higher voltage is always more stressful to the cpu.
But that is if it is beyond what it can handle.
Stock @ 250-600 will be not much diff to Ideal @ 250-600.
Although technically, Ideal will use less voltage and hence potentially use less power.
Why are you trying to use such profile anyways. I don't recommend it.
I recommend you stick with LV/ULV/IDEAL profiles. Many have issues using IDEAL voltages. If so, use LV or ULV.
Then just set the limits manually and set the avoid frequencies manually. (if desired)

I think I'm -very- lucky with my N900.
I set the xlv profile, tested each freq. up to 1150, and then started lowering voltages until it locked up/generated artifacts.
I have this running stably(tested with videos via Mplayer) for at least 5 minutes:
I'm not sure - Now that I have it (seemingly) stable OC'd up to 1.15GHZ, should I mess around with even more settings to improve batterylife/other stuff? Currently, I have it limited to 1.10GHZ; no need to run 1.15GHZ unless I find something that really needs it.

I don't think lowering the voltage much lower is going to give you any noticeable improvement in battery life. (Unless you max out the CPU at 100% with LCD turned off)
So if it's stable at xlv voltages, try ideal profile and if it's stable, no need to go much lower. It might look stable when playing videos/games but it may still be causing minute errors which may mean data corruption during file writes etc which you definitely want to avoide. Higher voltage does not mean "bad" unless it becomes the catalyst for overheating etc.

The main reason is this:
"9. I do not recommend using the command:
kernel-config default <name>
This makes your custom configuration the default settings"
This it seems to me is wrong, and I thought it had been pointed out before. Point 9 goes on to say that you get into a reboot loop if you have bad default settings. But Titan's kernel has protection built into it for if you get into a reboot loop, and I didn't see that mentioned in point 9. So I think it's inaccurate. You actually get a message saying that you rebooted unexpectedly and your default settings haven't been used.
Also, I like Jakiman's document and the way he is quick to update it if anything new comes up.
Here is the location of Jakiman's doc.

@jakiman: Incidentally, how DO you check for file write errors?
I'm running 500-850 on stock starving for around a month now (250-700 for another month before that) and I've seen little by way of rebooting or other errors. Or any OBVIOUS data corruption for that matter.
But seeing that other people struggle with XLV, I do get worried from time to time.
Also, are there any benefits from changing the number of steps the CPU cycles through? I mean, for 500-850, the CPU goes 500-550-600-700-750-800-850 - any gains by limiting that to, say 500-600-700-850 (by deleting the unwanted steps)?
Theoretical or otherwise.

Hi!
Ive been using... euhm... some kind of kernel, which Im not really sure of...
basically any time I restart my device, I input "kernel-config load ideal" followed by "kernel-config limits 500 900"
I havent had problems at all, only thing Ive noticed is when my device is locked and I slide out the keyboard and shut it without screen- or keypresses, sometimes it wont relock. this gets fixed by a restart, and Im not sure if its really related.
Works flawlessly at 500/900 on the ideal settings, besides the infrequent slidelock thing. Havent seen any drop or gain in battery, not sure if I should be.

Is it possible/smart to use only the two (500 & 1100) frequencies? No steps in between. The battery will drain much faster I guess.
Edit:
How much time does it take the CPU to go from 500 to 1100 with steps between the frequencies?
