I'm asking both. I've been bouncing back between Chad's and Tiamat. Last night I got brave and lowered my min mV to 775 @ the 3 lowest frequencies up to 245mHz. And then lowered the first two 25 bringing them to 800. And 245mHz to 825 vs 850 that it was. Using smartass screen off min 128-384max. Left my phone for about 30 min and no lockups. Then charged all night. No problems. I'm going to push it more today. Will report back.
[Droid Incredible Android Development] byrong:
Gotcha. I can't find any printed min/max specs online, but just like over/underclocking, I'm sure you're already outside the manufacturer's recommended range. They will always set ranges conservatively, and you are already using values that don't work on some people's phones.
[Droid Incredible Android Development] thisguy23:
@Chad. Do u have a lock on the kernel bottom min/max voltage? Because even if I set the numbers to 750 they only drop to 800. I like your kernel but you gave us permission to mess with the vaules. Thank you for your help.
[Droid Incredible Android Development] byrong:
Are you just setting the min that low? Just because you set a min does not mean that HAVS will use that value. For example, if you set 128000 to min 750, max 900, HAVS might still stick closer to the 900 level.

If you actually want to try going down to 750, set it as both a min and a max at the desired frequencies (just for testing).
[Droid Incredible Android Development] thisguy23:
That's what I did. 750min/Max for the 3 lowest freqs. Once I rebooted I was at a 800 min/Max.
[Droid Incredible Android Development] byrong:
Rebooting always resets the voltage table to its default. You need to manually set the values on each reboot or create a boot script that will set them.
[Droid Incredible Android Development] scottjb:
Is anyone using Preview 2 on MIUI 1.3.25.1? I had Preview 2 installed on CM7 #32 and am pretty sure it was charging quickly, maybe 1.5% per minute. I installed Preview 2 on MIUI and it charges slowly, maybe .5% per minute. Does the ROM ultimately control the charging rate while the kernel only makes it possible to charge more quickly?
[Droid Incredible Android Development] thisguy23:
I'm using testfix5. All great here
[Droid Incredible Android Development] thisguy23:
I see well I made my own voltages up to 1113mHz. Soon as I can get to my computer I will post my numbers. Is there somewhere I can go to see all of htc's values?
[Droid Incredible Android Development] scottjb:

[Droid Incredible Android Development] scottjb:
Thanks. Which ROM?
[Droid Incredible Android Development] thisguy23:
MIUI 1.3.25.1
[Droid Incredible Android Development] chad0989:
Absolute min is set at 800, absolute max is set at 1325.
[Droid Incredible Android Development] thisguy23:
Is it unstable lower than 800 and higher than 1325?
[Droid Incredible Android Development] POQbum:
it's unstable at 800 ;)
[Droid Incredible Android Development] chad0989:
Yes, its unstable at 800 (under any load) and 1325 is the max so people don't burn their phones up.
[Droid Incredible Android Development] thisguy23:
Here's my voltage table that is working stable, only been running for a few hours. Will report back.

[Droid Incredible Android Development] chad0989:
If this proves to be fine for people then I'll lower the minimum more for the next release since going to low is just going to lock up phones, not burn them up. Haha
[Droid Incredible Android Development] thisguy23:
Just a heads up. The numbers above 998MHz are not stable. I don't OC so if you do then take a look at them. I just had 2 lockups while trying to type this message. I'm running stress test on all freq's right now. Will let you know what I find out. Great kernel Chad.

If anyone is wondering...

[Droid Incredible Android Development] scottjb:
Second time this happened to me. I ran MIUI and after about a day, I lost 3G. The device kept switching between 3G and 1x. As soon as I put back the stock Sense ROM, I got solid 3G as usual. This happened on 1.3.18 too. :confused: Ever happen to you?
[Droid Incredible Android Development] thisguy23:
Not in a few months. Like in October 2010. All gravy for me.
[Droid Incredible Android Development] thisguy23:
? For everyone and before anyone ask; I did try to Google it. Lowering our voltage to save battery actually slows the CPU right? Ex: 384MHz @ 950mV vs 384@1200mV. Which is faster?
[Droid Incredible Android Development] chad0989:
Should be the same. Unless its unstable. Which could manifest itself lots of different ways.
[Droid Incredible Android Development] wildland:
Just a note to people testing voltages... Make sure you do some sort of stress testing. I had some setting which were working fantasticly around the house, but locked up the phone while using the gps and writing to the sd card simultaneously (google mytracks gps tracker).
[Droid Incredible Android Development] cheez99:
Chad, any plans on cooking up a new .38 kernel?
[Droid Incredible Android Development] thisguy23:
Very true. The only problem I have right now is a lockup while typing on xda. I raised 998 V 25 to 1225. Will report back but it seems to be much better now.
[Droid Incredible Android Development] morrisdan:
Chad, Time to put the oven on 2.6.38.2 and start cooking.

Ha. Thanks again for all your work.
[Droid Incredible Android Development] thisguy23:
Chad what is the new testamo? And is there somewhere you have a writeup on these test kernels?
[Droid Incredible Android Development] chad0989:
No write up on them as they're not for general consumption. I compile on my server, move the files to a web accessible dir and grab them to flash for my own testing purposes. At any given moment anything you find in there that I haven't posted or told someone to try, may not even boot or may be buggy as hell.

And testamo is just the name I've been using for testing the new display driver I'm working on.. since I can only test amoled because I don't have an slcd. Once I'm done with it I'll do the slcd part and have some others test.
[Droid Incredible Android Development] chad0989:
When I have the time. I patched one up to .38 the other night and it compiled but didn't boot and I haven't gotten a chance to mess with it since.

Right now there isn't too much of an advantage to going to .38 as many of the major changes I have pulled into my .37 testing branch already or don't really affect us much. Hence why I haven't spent too much time on it. I likely will get around to it at some point though.
[Droid Incredible Android Development] thisguy23:
Thank you for explaining. Can't wait for some new kernel goodness
[Droid Incredible Android Development] SomeGuyDude:
I just can't wait for the latest .37 update!
[Droid Incredible Android Development] jprow507:
I just can't wait for the Sense update LOL!

New voltage tables for me

Well, since I got rid of the flu, ive started tweaking my voltage tables again.

I had to up a few higher ones in the 1ghz range. I did more testing outside of the home, in different areas where signal was less. I've used the table below for about a day with no problems. In that time period i have: Watched a movie, used gps and maps for about 30 minutes, installed a few apps, played 3 versions of angry birds and Air hockey, played mp3's using Miui's built in player and also Winamp, surfed the web using 3 different browsers, used the phone for about 2 hours of phone calls, loaded up and played with misc apps, and sent a few messages here and there. So far no lockups.

It's nice to see others tweaking the voltage tables too. I tried to use 800 800 as my lower voltages for the 128-245 range, but my phone seems to like 800 825 much better.

Oh and For the last 24 hours, I overclocked the phone as high as it goes, so I know the voltages at the high end work for my phone at least. Anyway, someone who has been tweaking try my numbers and see how it goes for ya. Thanks!

Just dropped by to say I got AMAZING battery life the last few days with the preview 2, and with quick charging my phone was full again at the end of my 45 minute commute. Had the first lockup since installing it the day chad mentioned it.

Very nice work, chad. Best kernel I've ever used. Donation sent.
[Droid Incredible Android Development] Jrkoffjonson:
If you need a tester for slcd shoot me a pm. :)
[Droid Incredible Android Development] bradm23:
Testing out preview 2. Battery life is better than 3/18 release. It does seem a little bit choppier not being as smooth as slayhers or 3-18. I also had an issue where the lock screen is very dark untilled I unlock it. I am not sure if this is kernel related, however I didn't notice this happening with 3-18.

Thanks for all you hard work Chad!
[Droid Incredible Android Development] win7x64:
This happens to me whenever I am in the sun :-/
[Droid Incredible Android Development] JetBomber117:
This happens to me randomly a lot. Not sure what causes it.

I also have the opposite, where I'm in the dark and my screen will come on full brightness at first.
[Droid Incredible Android Development] win7x64:
Oh, yeah, that's what I meant. When I'm in the sun, the screen comes on dark. When I'm in the dark, the screen comes on at full brightness. I have the brightness set to 100%, non-automatic (since that's the only way to see anything when i'm in the sun >_> AMOLED)

[Droid Incredible Android Development] wildland:
Since you're on CM7, give the automatic backlight a chance - and set custom levels -- CM Settings->Display settings->Automatic backlight->>Use custom-checked->>Edit other levels... in there you can easily determine what your current light sensor levels are and set appropriate brightnesses - on my phone anything above "2600" sets screen brightness to 255 (100%) and I can walk out of my dim house into full sun and within seconds my screen is fully bright and as readable as it gets... Works for me (there's much more detailed discussion in the giant CM7 thread for more info/advice on setting custom levels).
[Droid Incredible Android Development] chad0989:
Here's another preview for those who are getting itchy since its taking me so long to get this out...

Preview 3 is a beast! Soooooo fast and smooth. Your the man
[Droid Incredible Android Development] GooTz66:
Flashing now!
[Droid Incredible Android Development] d08speed3:
Just gotta say that this preview is sooooo fast. Feels like a 2ghz phone haha
[Droid Incredible Android Development] ilhe1s:
Now I'm really interested. As soon as I get a decent charge I'm going to flash!
[Droid Incredible Android Development] HoochieCoo:
I'll give the latest a go tonight. SLCD here... will let you know.
[Droid Incredible Android Development] Div033:
I was experiencing some choppiness with preview 2 so I went back to the 3/18 build. I've just installed preview 3 and am not noticing the choppiness I had on preview 2. So far so good! Amoled here.

Sent from my Droid Incredible using the XDA app.
[Droid Incredible Android Development] crondable:
Battery seems better then preview 2, initially at least. I can agree with everyone else as well, seems much smoother.
[Droid Incredible Android Development] HoochieCoo:
Maybe its just because people are saying "OMG its so fast", but it does seem faster. Or smoother. Or something.

Edit: SD card speed improvements? Ran a speed test and its much higher than before.
[Droid Incredible Android Development] byrong:
I'm not trying to be a jerk or completely dismiss your observations, but I think making judgments about battery drain is very premature after only a few hours (3 hours after Chad released). It may well turn out to be true, but I think a much longer observation period is appropriate.
[Droid Incredible Android Development] zerf:
Sorry if this has been covered before but can we still flash the voltage tweak.zips with these preview builds as well?
[Droid Incredible Android Development] Div033:
Can someone else try running quadrant? I can't seem to get past the database writes benchmark. I'm not usually huge on quadrant scores and rely more on what I percieve, but curiosity got the better of me. I know this is only a preview kernel so I half expect Chad already knows about this, but if not then there you go!

It could also be my error somehow, hence my request for others to try running it with preview 3.

Edit:

It was just taking abnormally long. Again this isn't a huge deal to me, just being a tester. I scored 1150 first run and 1250 second run.

Sent from my Droid Incredible using the XDA app.
[Droid Incredible Android Development] zerf:
Well I just went ahead and flashed preview 3 then the voltage zip after. It booted fine for me. I also ran quadrant and got 1091 first run and 1262 2nd run underclocked to 883 on smartass gov :)
[Droid Incredible Android Development] byrong:
Sure, I just ran it 5 times. Highest score I got was 1585 (the fourth run)
[Droid Incredible Android Development] byrong:
Voltage tweaking still works, yes.
[Droid Incredible Android Development] win7x64:
Flashing preview 3 now. I tweak the voltages with a script that I put in /etc/init.d/. I tried out the voltages that were posted a few pages back but found them unstable at a few speeds (883, 921, and 930, and any overclock).

What is everyone using to test overclocks? I start out with just basic usage with the clockspeed locked at that voltage, and then I run the following apps: CPU Benchmark, Linpack for Android, and Quadrant (I disregard the results--I just check to make sure that it hasn't restarted). Then I run StabilityTest for as long as I can afford to at the time (sometimes only 5 or so, sometimes in the 20's).

Edit: Here are the voltages that worked for me:

http://dpaste.org/rXLH/raw/

Asterisk means thoroughly tested. On the 960mhz, though, a min of 1.1V worked for me, but the 921.6mhz would be unstable at all mins but 1.175V (weird, the max works at 1.175V too). I'm not sure how HAVS works, or what min really means, but I just moved 960mhz up to 1.175V because having a lower speed have a higher voltage made me doubtful of its accuracy :(

Does anyone one know how HAVS works, and if it is okay to have a min of over 0.1V less than the max?
[Droid Incredible Android Development] ilhe1s:
I'm running CM7 RC4 ran Quadrant and didn't get anything out of the ordinary. I got 1144 and that's the usual for me, but I will say that the P3 kernel flies. Looking forward to more. Keep it up Chad!
[Droid Incredible Android Development] Jrkoffjonson:
Ran quadrant too just for the hell of it with 235 megs of ram free, got 1215 on CM7-RC4 on your latest preview..not that quadrant scores really matter but besides that its been running VERY smoothly and I've been loving every build you have been providing us Chad! Can't wait for the next release and everyones incredible I work on and root I will put your kernel on :)

If you ever need testers just let me know, I work for Verizon so I'm willing to toss a phone away more or less haha
[Droid Incredible Android Development] crondable:
Exactly why I said initially. I charged fully before flashing the new kernel and noticed slower battery drain right off the charger then preview 2. So initially, battery seemed better.
[Droid Incredible Android Development] win7x64:
Anything from 100% to 90% of the battery does not matter since your phone is lying to you about the capacity anyway.

And, yeah, benchies don't mean a whole lot in terms of actual performance.
[Droid Incredible Android Development] andrix10:
Preview 2 is pretty good
[Droid Incredible Android Development] bilbobrian:

[Droid Incredible Android Development] phaze one:
Downloaded preview 3 last night. SLCD here, so far everything seems to be running fine. I'll update later today.
[Droid Incredible Android Development] blastthenoise:
Are the preview kernels gb only? I'm dying to flash something. I switched to froyo miui weeks ago and I haven't flashed anything since
[Droid Incredible Android Development] rfarrah:
Pretty sure they are AOSP only. So I assume if you're running MIUI, you should be okay.
[Droid Incredible Android Development] texanaustinite:
First preview was giving me gps issues. Gps would lock on just fine using gmaps, but after a few minutes would lose signal, use towers for a few seconds, then back on gps for a few minutes before losing signal again.

No issues with gps on with stock kernel. Going to try preview3 now. CM7 #36 btw...

Thanks Chad.
[Droid Incredible Android Development] texanaustinite:
Use the froyo version.
[Droid Incredible Android Development] andrix10:
I mean preview 3 lol
[Droid Incredible Android Development] scottjb:
You can move to GB MIUI and use the GB kernels. 1.4.8 for the Inc should be out by tomorrow.
[Droid Incredible Android Development] blastthenoise:
I would except from what I just read at miui dev they have removed a few features in the power control widgets that I use and I have a few Apps that don't work with gb yet.
[Droid Incredible Android Development] phaze one:
So I downloaded preview 3 last night. Been running it all day. I'm an SLCD Inc and I've encountered no bugs or problems. Battery life seems comparable to 3/18. Snappy as usual. Will report back if I encounter anything unusual. So far so good, nice work Chad.
[Droid Incredible Android Development] Gahh Its Lee:

[Droid Incredible Android Development] J2theMatt:
Agreed to. I just wached 4 hour long tv shows I'm still at 26 percent.
[Droid Incredible Android Development] wildland:
Yeah, I'm getting that on CM7 Nightly 34 + Preview 3 here but I've done zero testing, so I can't even attribute it to the kernel myself - definitely an issue with one of 'em (or the combo :confused::p). If I have time I'll try to do some testing (including the latest nightly) tomorrow.

Edit: forgot to mention that otherwise preview 3 is performing fantastically for me...
[Droid Incredible Android Development] kioshi:
Preview 3 is insanely fast on cm7 rc4!

I really appreciate your work....this is my first and onlu kernal i have trird...the best done right the first time.
[Droid Incredible Android Development] d08speed3:
I wanna say battery life on Preview 3 isn't as good as preview 2 hmmm? Its not horrible tho. Ill have to keep observing.
[Droid Incredible Android Development] itsmefu:
Preview #3 is running great for me on cm7 latest nightly. Keep up there good work, I'll be donating as soon as I can.
[Droid Incredible Android Development] chad0989:
The kernel doesn't affect the gps. Gps is all radio and software. So it was likely some random issue since gps has always been flakey on getting a lock.
[Droid Incredible Android Development] scottjb:
Chad,

FYI--been using Preview3 on MIUI 1.4.8 for the past couple of days and it works well. In general, MIUI does not seem to allow fast charging like CM7 does, not sure what's going on there. I will pay closer attention to it to confirm. CM7 charges at about 1% per minute for me until it gets to about 90%, then it slows down. MIUI does not seem to get to 1% per minute--it stays a little lower than that.

On CM7 my phone would not wake on the first power button tap with the latest preview kernels and Smartass with 128 or 245. At your suggestion I tried Interactive and the problem went away. Interestingly, on MIUI the phone wakes on the first tap with Smartass and 128 as the minimum frequency. The only thing I noticed is a slight lag acknowledging the swipe to unlock MIUI at 128, but it works.
