ooohh kids :)

There is a link in first thread that points out to original VDD interface thread and explanes everything..

Or just modify the scripts I provided and flash via cwm so it applies on every boot

add drawer lag can be a part of a different launcher beeing used.. and, yes it's possible to lag because it increases speed of you cpu gradualy, try using Interactive governor instead

OC/UV thing is to try to achive the fastest DHD but the most power conservative..

I've seen people here that can run only my normal voltage version kernel and anything below that freezes their DHD. But there are DHDs that can run at very low voltages, than I've made scripts to lower voltages as they like ergo lowering battery consumption

Hope it's more clear now for some..
[Desire HD Android Development] LorD ClockaN:
New version UP

Hope recording is working as expected

No need to install any apk.. the update will do it for you

removed version with Simple I/O scheduling and normal BFQ for CFS version

everything else stays the same..

If you allready have vdd script applied, no need to remove it, just flash the new kernel
[Desire HD Android Development] vatranxxx:
Hey, 4.3 is much smoother than 4.4 :/

The new version is laggy when i scroll through the settings for example.

I use Bfq cfs.
[Desire HD Android Development] io53:
4.4 is smooth as butter for me. Try changing form smartass to ondemand.
[Desire HD Android Development] vatranxxx:
Thx for the reply but i tried ondemand too...normally i use interactive
[Desire HD Android Development] LorD ClockaN:
I didn't want to comment on that reply before, was waiting for someone to reply :)

4.4 smartass works great here..

Maybe for 4.5 I can increase MIN Wake Up Freq so it automaticaly wakes up on 700MHZ, not 400 like it's set up now.. than It will be, maybe, smoother
[Desire HD Android Development] Leechoonhwee:
Noob qns. So we shld flash the CFS kernel first then the UUV script all via ROM Manager yah???
[Desire HD Android Development] LorD ClockaN:
nah! :)

don't know about rom manager, I use it only for backup..

Boot into recovery and flash the kernel.. test it and than gradualy go to UUV script, because maybe your DHD can't work on very low voltages
[Desire HD Android Development] BumAround:
LorD ClockaN,

the holy grail I sought after is the best combination between smooth-ness and significant battery saving possible. Not really crazy about some benchmark scores or over-the-edge OC. :)

thanks.
[Desire HD Android Development] lukesky:
Okay, some feedback for the 4.4 version. I tried the VR CFS version with UUV and PUV and both worked. But looking at the extreme undervolt of PUV and I'm not so comfortable with that, not sure if a CPU can get damaged with too little voltage so I'll probably raise it up a bit myself.

I also tried the call recording. It works when I choose wav but doesn't work when i choose mp3. Anyway the recording quality is better, but the Call Recorder app doesn't have as many options as compared to Total Recall, so I'm going back to Total Recall to record my calls
[Desire HD Android Development] kuceens007:
Which cpu frequency? :D
[Desire HD Android Development] LorD ClockaN:
No damage of low voltage, only high

How do I know if I want BFQhs or VIO? I know I want FCs instead of bus, but not sure beyond that. Are the differences explained somewhere?
[Desire HD Android Development] Leechoonhwee:
What are the symptoms that my DHD cant work on low voltage? If there are problems, is there a script to go back to default?

[Desire HD Android Development] LorD ClockaN:
Check which one works best for you.

It depends on the type of work/stuff you do on your dhd

@Leechoon;

You get freezas and reboots

Have you looked at the link just below those sripts?

i listen to music and go on internet but have screen on quite a bit, what setup shall i have?
[Desire HD Android Development] stony2k:
Got the same Problem here too. I thinks it custom rom, not kernel related.

While using the smartass governer, it doesn fire up the max cpu frequeny immediately. It turns the frequery up step by step. This can cause the lag issue.

Try to use ondemand governer instead. If requested, it skips the other steppings and sets your max frequeny emmediatly, to have just in time the whole power handy.

It can cause freezes, lags and stability issues. If the CM7 team would use such settings/kernel for every "dumpuser", no one would use CM7 anymore. Undervolting is made for experienced users, which are willig to test a lot of setups, bevore they are really satisfied.

Some poeople are want to flash a rom and nothing else. They don't want wo test and try etc.

Undervolting doesn't harm the CPU due the low voltage can't burn your cpu.

Hellow,I want to join our school's wifi,it shows that it connected successfully,but every software shows no net connections.But in the same location,My iTouch 4G can browse websites easily, Now I 'm using itouch to post.I only want to know why my dhd has this problem,because I can use wifi in my home.Sorry for poor English.Thanks.
[Desire HD Android Development] LorD ClockaN:
Whatever :)

try setting min freq to 122, and max to 1075, governor smartass or interactive, and thats it...

If your dhd can handle low voltages try using -25 or -50 scripts....

UUV and PUV is better choice, but not every dhd can handle them..!

I was just yesterday on a little tour with my bicycle and was listening to Bon Jovi via music.apk (getting ready for the concert) for about half an hour.. no problms whatsoever... min 122, max 1380 as allways... I couldn't set the max volume on my headphones because it was too loud :P
[Desire HD Android Development] Freakgs:
Mine for example freezes upon boot and if it somehow manages to get beyond that it starts freezing later one.

I can only use -25mv.

So I was a bit unlucky with my phone (it also can't take 120 min frequency)

Update: Had to switch back from PUV to UUV, due my random os freezes.
[Desire HD Android Development] d.brown:
hey lord which case do you have is this the gel one from ebay?
[Desire HD Android Development] substance12:
Noob question. Are the first 3 links the kernels and the later 4 scripts used with them? I just flashed the cfs bfq without anything else. I'm not interested in extreme optimization or uv... But I do want the other benefits of the base kernel.
[Desire HD Android Development] gordec:
Thx, so if I just flash the 4.4 BFSqh CFS version, is there any additional voltage settings I should tweak? I tried OC/UV when I had the Samsung Captivate. I went up to about 1200hz and UV most to 100, and didn't notice any change in performance or battery life.

My main focus is to get better battery life from the stock CM7 without sacrificing performance. Any recommendations?
[Desire HD Android Development] LorD ClockaN:
you can see by the size of the files that the last 4 are scripts :)

Case is from ebay, but some sort of silicon non-transparent darkblue with barely visible sparkles :)

mercury is the name on the back

16$ I think

@stoney:

up the voltage some more in PUV script

@d.brown:

Just compiled newest cm7 for me with gps fixes and went to try it out and realized that the ****ING case was blocking gps signal.... and phone signal also.. SOB!!!
[Desire HD Android Development] Neoman:

[Desire HD Android Development] stony2k:
Right ;)

Any recommended values for editing the PUV-script?
[Desire HD Android Development] LorD ClockaN:
ADW EX.. you can chose the screen translations

@stony:

up the voltages from min to 1380 ba 25mV and try

that is still lower than UUV script

Are you running MIN 122 or 230?

If 122, set it to 230 and than try
[Desire HD Android Development] magnumforce2006:
Inspire 4g user here (in conjunction with the Ultimate Droid ROM). Just wondering what kind real-life battery advantages there are to using the UUV version as opposed to the full version.

Also, what governors tend to be best for someone who wants great battery but also hates, lag, lol. Smartass often lags the ui for me, but I've read OnDemand (which is smooth as butter) uses quite a bit more battery.
[Desire HD Android Development] stony2k:
I was already running on min 230.. :(

Already tried interactive-governor?
[Desire HD Android Development] lynxboy:
Use Ondemand with a SetCPU profile for screen off. I'm on 4.2 CFS UV and battery life is superb using OD and a screen off profile of 122-307. Make sure you calibrate!

[Desire HD Android Development] winsettr:
Would Interactive be considered between Smartass and Ondemand in terms of balancing power consumption and performance?

Running v4.4 CFS with a slightly modified PUV. No problem so far, Lord. :)

Also, I feel like it's smoother than 4.3 when scrolling the UI. ;)
[Desire HD Android Development] BumAround:
First was v4.4 BFShq CFS, PUV script, with all smartass, interactive, and ondemand governors tried one by one, and didn't like the intermittent lag. Min set to 230 as always. No freezes whatsoever.

Been using v4.4 VIO CFS instead with ondemand, PUV script unmodified, and it's NICE & steady! :)
[Desire HD Android Development] gordec:
Can the more experienced UC/UVs post some of their set up. Mainly what Kernel version and SetCPU settings, and battery life vs performance? Be useful to us nubs for reference. Thx
[Desire HD Android Development] lukesky:
is this the gps fixes that u're talking about : ace: use qcom libloc_api (MERGED)?

do u know what this gps fix does? I haven't upgraded to this latest cm7 version yet but my gps works fine even though i have a similar case as yours.. mine's a rubber-like case, not silicon though. I also read somewhere that such cases really do obstruct the gps antenna but i guess that's a trade-off between protection and functionality

[Desire HD Android Development] winsettr:
If I am getting UI lag with smartass at 230/1228, is it recommended that I raise my minimum speed up a level or two, or switch to ondemand/interactive? I know raising the minimum speed reduces the UI lag, so my question is which method should yield better battery life? Thanks!

[Desire HD Android Development] stony2k:
Have a look at this: http://xdaforums.com/showthread.php?t=937080&highlight=battery

Can't tell you this for sure but I think yes.

I'm running on smartass, stepping 122 - 1075 MHz. Kernel and UV @ my sig.

Are you running with PUV? If higher (>UUV) you can change your min-frequency to 122 and try ondemand/interactive instead. There you should get better results.

Tried -25mv settings? ;)

Edit: Here are some gorvenor infos taken from http://www.setcpu.com
[Desire HD Android Development] skinny-dipper:
Thx bro i'll give it a try :D
[Desire HD Android Development] zenkinz:
I have been running CM7 stock for awhile, and finally decide to try out LorDMod customise kernel. Unfortunately, I am not getting good performance (both qualitative through quadrant and qualitiative through own gut-feel) from both v4.4 BFS and CFS. I didn't try to undervolt version, and would think it'll be worst than w/o undervolt.

CFS seems to be worst, quadrant only shows 1000+ score and with BFS overclock to 1.5Hz (same as my stock CM7), I could only get 2400 (on stock CM7 I could get 2800)

I know quadrant doesn't mean anything, but so far the score versus my own experience are very consistent, i.e. the phone feels lag.

I'm back to stock CM7 now. (even my restore feels faster than the CM7 stock kernel i flashed) wonder if the custom rom is based on a different branch of CM7 source code?
[Desire HD Android Development] Mullicious:
Hey guys, could I just double check I'm doing this right?

Basically, downloaded 4.4 - BFQ - BFS, wiped cache, and Dalvik, flashed all well. Stuck the cpu on 122-1228, On Demand govenor.

This ran smoothly, very nice infact, so; I've downloaded -25mv, flashed it. (Didn't wipe anything this time?) And the phone is stable, and relatively smooth. However, in the CPU options (Using MDJ's UD 1.8), the lowest voltage is still 122. I then flashed -50mv, to which the phone crashed. So, I cleared cache and dalvik again (God knows why.) And reflashed the -25mv file.

The phone is on, stable, but still only mentions 122 as minimum. Smartass is a bit choppy, but On Demand is butter.

So basically, what I'm wondering is; have I done this right? Any mistakes? Am I running at 122, or -25mv from that? Just a tad confused, and slightly new to the kernel/UV game.

Also, if -50mv crashes, will the UUV be totally out of the question? Is that the next 'Lower' voltage'd file?

Hope someone can help, but really nice kernel Lord, smooth as hell, my phone has never been as snappy.
[Desire HD Android Development] stony2k:
Just edited the voltages as you told and flashed them. Wish me luck for now ;)

You did everything right, congrats for this :)

Well, if -50mv crashes, UUV will crash too, because its more undervolted then -50mv. But you can try to set your min-frequency to 230 and try -50mv again. Do you have setCPU running or only UD with cpu options?
[Desire HD Android Development] Mullicious:
I just installed setcpu, however I'm guessing that maybe it's a bad idea to have two CPU controlling programs going at once?

I'll try the -50mv at 230, thanks. I think I've got the jist of it now!

Edit: Thanks, It's very rare I get things right first time, so I'm glad I got it going. Not exactly rocket science, but hey-ho, whatever gets you through the day. :p
[Desire HD Android Development] lukesky:
firstly, what CM7 build are u using? is it the latest? I'm using #42 with Lord's 4.4 CFS VIO UUV kernel and it's definitely faster than what you're experiencing. Quadrant gives me 2400 at 1075mhz.

secondly, what gov are u using? with smartass i realised that it's not the max cpu freq that u set that determines lagginess in the launcher, it's actually the min freq. I'm using 230mhz as the min freq and it feels fine. if it doesn't feel fast enough for you, up the min freq 1 notch higher and see if that helps.
[Desire HD Android Development] justin0307:
Hmm I am on CFS cm7 too but I get scores of around 2500-2800. Min 230 Max 1382 ondemand.
[Desire HD Android Development] Mullicious:
On my setup that I mentioned above, I get 2700 quadrant on 122-1228, On Demand.

Just pumped it up to 1843200, performance and got 3500 quadrant. Pretty nice scores. I've found that is my phones limit, any higher and it crashes totally. WIthout fail. I'm glad I know my phones OC, and UV limits however. Just interesting. :)

Is it bad to have two CPU programs? (UD's own, and SetCPU)? Seems a waste not to have SetCPU since I paid for it, but if its going to cause conflicts, I'll leave it out. :p

Edit:

On SetCPU, I've set a screen off profile with Powersave. (122-460) and no hang ups/freezes during screen off time. Really fast to be honest. Very impressed.
[Desire HD Android Development] alexmason14:
Just thought id post my stats as tbh i f@%&$$" love this kernel :P Im using 4.4 Vio CFS UUV, on demand min 230mhz and max 1.22ghz with an additional screen off setcpu profie of 122mhz to 230mhz and my Dhd is flying, even more so since I added some new fly in UI animations to cm7 via metamorph, seriously i havent encountered ANY lag. Im also on the latest cm7 nightly. And my battery lasts for on average 16hours, moderate use, alot of music via my bluetooth headset, alot of web browsing, instant messaging and texting with a decent amount of calls aswell as some gaming. This is the best kernel i have ever used. Money will be coming your way lordmod! Oh and i get 2500 on quadrant with this setup ;). Average idle is 2ma, and 100 to 250 for music, browsing etc. :D

the -25 patch on mine, allows for boot, but the seconds its booted up, the phone completely freezes, even when I flash the working kernel I had before that though I get the same problem, the only way round is to restore my nandroid backup which has the working kernel already, really weird!
[Desire HD Android Development] LorD ClockaN:
Flashing kernel after script update doesn't remove the script

Use restore defaults script from first page.

A small request if you'd be kind enough to create a version of 4.4 CFS VIO without the 20% volume boost? or say 10% volume boost instead? Thanks
[Desire HD Android Development] michelD:
Lord ClockaN,

Really amazing !!

These are my results in short:

1° Stock original Froyo quadrant ~1.800; Standby consumption ~8mA (some peaks)

2° Coredroid 5.4 (2.3.3) quadrant ~1.400; Standby consumption ~5mA (but a lot of peaks !!)

3° Cyanogene 7.0.2 (originale kenel) quadrand ~1.800 Standby consumption ~11mA (no peaks)

4° Cyanogene 7.0.2 + kernel LorDmod 4.4 VIO: quadrand ~2.400 Standby consumption ~3mA (and sometime less !!)

NB:

all quadrant tests @1GHz. No under/overvoltage.

And of course everinthing run like a charm: no lags

I will now test with undervolting progressively...

Great successfully flashed 4.4 BFQhs - CFS + -50 edition 122/1380MHz. I am currently running Stability test since I used to run it when I OC/UV. Generally the teaching is to get 30 successful runs to deem it stable, then I run Neocore for another 10 min.

Anyone else do that? Or by able to boot into phone is a sign for stability for this Kernel?

Good I ran it, it froze @ 1380 during stability test. Gonna tone it down to 1200.

I guess there is no way knowing if it's the UV or the OC that's messing my phone up.

Update: Froze again at 1280, now down to 1150. See how this goes.

If this fails again, may need to Reset.zip and flash -25. Do you guys wipe dalvik and partition again if all u do is flash a different voltage setting?
[Desire HD Android Development] jpinky:
Thats probably overkill. Normally an UV fails immediately or within about 3 minutes of usage and definitely during or just after a quadrant/other bench run. If you're OC'ing and want to see the temperature effects then yeah, a few runs should show it.
[Desire HD Android Development] winsettr:
After some tweaking I am really loving this kernel, specifically BFQhs 4.4 with UUV; 122/1228 with Ondemand governing gets me around 12-18 hours depending on use and Quadrant scores dance around 2500. No lag, vs slight but annoying UI lag with Smartass.
[Desire HD Android Development] justin0307:
I have a question regarding voltage.

Since my min 230 and 307 have the same voltage, does that mean they consume the same amount of power? If I bump the min to 307, would that consume more power? The difference is so little that it might not make a difference, but I want to know. Thanks in advance! :D
[Desire HD Android Development] marshy73:
I'm on the same settings as you but using conservative governor instead.

Try it out as its supposedly the same as OnDemand expect not so aggressive.

There is negligible UI Lag and its really a good in-between of OnDemand and SmartAss.

I and a few others are noticing a significant drop in cellular speeds after flashing this kernel, like it doesn't support HSUPA.

Same phone (Inspire 4G), same radio (one listed in my sig) will get H+ speeds on the CyanogenMod 7.0.2 stock kernel but will drop to the standard 3G speeds once I flash to LorDmod. Phone status claims it's in HSDPA mode. Any suggestions?
[Desire HD Android Development] justin0307:
Just try different combinations and see which one you like the most. Read the first post about the differences between CFS and BFS before making the decision.

After you start to get comfortable with it, you can try the undervolt scripts. ;)
