OverClocking 101

FYI my mistake as I just talked to P3 he has not updated them o his kernel page yet. I thought he already had done them. He did mention he will try to get them updated this weekend at some point tho.

Thanks! I'll check the Web site again in a couple of days.

What speed are you after?

I think I have 1 or 2 of his kernels with the CPU temp monitor I just don't recall which speed they were. they are for Froyo tho and if I'm not mistaken they were of his LV with the 125 slot. They are on my comp at home, and seeing as I'm now onto the X i can't check atm.
 
Sorry if this question has already been asked:

Would there be a difference in voltage used or more importantly (for me) battery life between theses two situations:

A 125-800mhz kernel running on demand set 125-800
A 125-1250mhz kernel running on demand set at 125-800

Would the overall higher mhz kernel use more juice than the 800mhz kernel or vice versa enen though with all other settings being the same?

I hope my questions makes any sense.

i dont believe so. they top speed that each is set to is the same so its not gonna make a difference. its just the second one has the ability to go higher..
 
There are fewer steps between 125 and 800 on the 1250 kernel. That means you'll ramp up and down faster, but you'll be going "full bore" more so you might use more juice.

oh yea i forgot about that. man its been a while since ive been able to change kernels...
 
For instance, cvpcs has his 125Mhz Standard Voltage set to 0x27 and his Low Voltage set to 0x20.
Where did you find this info? I've been asking around and poking around with limited success. Is there an app or terminal command that will tell us this info on the phone, or do we have to just ask each kernel dev and hope to get an answer?

I'd like to compile a chart of each kernel's voltage at each clock speed to get clearer comparisons between each rather than just going off the arbitrary label of "LV" or "ULV".

I have asked most of the Kernel devs for that very information. Only two devs ever gave me a usable answer, P3Droid and cvpcs.

cvpcs gave me this link: arch/arm/mach-omap2/board-sholes.c at android-omap-2.6.32-sapphire from cvpcs's android_kernel_omap - GitHub

P3Droid gave me a link but at present I am unable to find it in my history.

Okay, so the information is only available at design time. I was hoping for a way to find it at run time so we don't need to rely on the devs' cooperation.

As expected, cvpcs handles this nicely by having his version control repository public. You can see he at least uses preprocessor flags so he can easily build all the same slot sets. I get the feeling P3Droid does this as well, as his sets seem to be consistent each release. I wonder if other devs do this as elegantly, or if they just manually tweak the source for each set of slots. I'm willing to bet that and a lack of an public VCS (if any VCS at all) contributes to the difficulty of getting this info from other devs.

I missed your post. I'm looking for the 125 - 1250, either LV or SV. Both worked well.

Sounds good, I'll take a look and see what I have. I kinda forgot myself about checking into it for ya. luckily my email notification came threw this time on the thread post.

If the kernel has a voltage in one or more of the seven slots that is too low for your phone, you will get overheating from the OMAP3430's ECC module kicking in to fix data read/write errors.
Do we currently have a good way to determine if/when this is occurring, or is it just watching for high temps and lag together at unexpected times?

I, at present, have found no way to monitor the ECC kicking in. So lag and heat are currently our only signs.
