i use v4 710 w/infinte's .6 stock odex. v4 710 always reads @ 691.21mhz.

what is the reduction in voltage with the uV version??

thank you thank you
[Hero CDMA Android Development] azr6:
So what is the difference between these two below if I have the damage control rom? One is just a little faster then the other?

Damage Control(has ramdisk from 2.09,will work in 2.08 and 2.09)

DarchKernel vUV 768mhz for DamageControl

DarchKernel vUV 710mhz for DamageControl

Did the new kernal come out or is uv the latest one?
[Hero CDMA Android Development] urushiol:
They are identical except one has a default of 768mhz and the other has a default of 710mhz. Both can be clocked to a max of 768 using SetCPU, or Overclock Widget.

vUV is the newest, hoping to release a revised UV with htc synaptics driver once darch gets the bugs out. He compiled one a few days ago, I plugged in the ram disks and such, and flashed it. It goes for about 2 minutes, then hardlocks, regardless of CPU clock or memory management settings. So it's most likely going to be a few days, Darch is going to have to locate the problem, recompile the kernel, then I'll need to mate it up to the proper ramdisks and test it.

We'll get there!
[Hero CDMA Android Development] azr6:
Thanks for the response. So is there honestly a big difference when it comes to 768 or 710 mhz? Seems kinda odd that those are the two choices...almost like their is a logical reason for it.

Maybe so you aren't run your phone at max speed all the time? With this kernal does it ever slow the phone off? Maybe while it sleeps or such.
[Hero CDMA Android Development] chromiumleaf:
Some phones can handle processor speeds of up to 768mhz, other phones can only SAFELY handle speeds of 710mhz. I think the 768 people are a lucky few... I can't say if there's much of a difference because I've never been able to run my phone at 768mhz.

These kernels have an 'ondemand' feature -- meaning that the processor automatically goes really fast when it needs to, and slows down big time when it's not needed (such as when the screen is off and/or the phone is sleeping, etc.) Generally this way you get better battery life out of your phone on an average day.
[Hero CDMA Android Development] azr6:
Gotcha. So is there anyway to find out if your phone can run the faster kernal or do you just do a trial and error type test.
[Hero CDMA Android Development] junkshow:
You could use Overclock Widget or SetCPU to see how fast your phone can run before it locks up.
[Hero CDMA Android Development] urushiol:
Usually the first things to start messing up if your on the ragged edge of stable are the camera will start crashing and you will start getting network drops that require an airplane mode toggle or restart to get to reconnect.
[Hero CDMA Android Development] azr6:
Which doesn't happen when running at the 710 kernal?

I will give that one a try first and see how it goes.
[Hero CDMA Android Development] c00ller:
Can't wait for vUV with HTC synaptics :D
[Hero CDMA Android Development] Papa Smurf151:
Putting the final touches on my next rom tonight. Any chances the new UV kernal will be up by then
[Hero CDMA Android Development] urushiol:
Currently darch has been unable to find a solution to the lockup with the new UV. I will keep everyone posted!
[Hero CDMA Android Development] xzjn9p:
Is it possible to get a kernel just like this (691 no free mem tweak) for fresh? I personally think V4 is the best for performance. I'm near a charger all day and UV really isn't that important.
[Hero CDMA Android Development] darchstar:
here u guys go, my latest kernel with all meh latest mods, which includes undervolting, and some mods found in cyanogen's supersonic kernel. this zip only includes a zImage and some modules. if u are a noob, wait for someone who knows what they're doing to put it into an update.zip, or start learnin :p

darchroms.pocketdevelopers.com/zimages/do_not_flash-kernel_wlanko_ramzswap.zip

lol, wtf r u talking about? sorry, im not gunna read this whole thread to find out :p.
[Hero CDMA Android Development] foolforfood:
Darch, this seems to be awesome and amazing, just curious if this includes the HTC synaptics drivers?
[Hero CDMA Android Development] johndoehizzle:
any1 wanna make the new kernel flashable? lol pleaseee :o
[Hero CDMA Android Development] urushiol:
I just saw this, I'm on it =) Thanks darch!
[Hero CDMA Android Development] whatsleft4her:
how soon til we see a new release?
[Hero CDMA Android Development] urushiol:
You sent me a UV kernel with HTC synaptics, which after 1 or 2 minutes after boot would slow and eventually lock up. I sent you a PM about it, and a logcat. =) DOH!
[Hero CDMA Android Development] BlaqkAudio:
From the looks of it, it does. I have it flashed on my phone right now, and it's working wonderfully.

I sent urushiol my update.zip for him to test out. It's based off of Koush's AnyKernel template, which theoretically could be flashed to any ROM.
[Hero CDMA Android Development] urushiol:
I ended up falling asleep last night, I just woke up and have to get ready for work quick! I'll dive in after work, later guys!
[Hero CDMA Android Development] Androidious:
I'm still noob enough to have to ask these questions below:

So, is this kernel able to be used with DarchDroid 2.7 at alll or no since DD 2.7 is AOSP? I haven't a clue about all this kernel stuff yet, as I'm still learning. Just wondering. If it is at all possible to use with Darchdroid 2.7, would anyone be able to make it flasheable and starting out at 710 mhz? Thanks to you all! Ya'll are the best around.
[Hero CDMA Android Development] chromiumleaf:
Yes, I think you would be able to use it on DD2.7. While DD is an AOSP ROM, it's still on an HTC phone....so the new kernel with the HTC synaptics driver should work better for anyone no matter what ROM they're using.

Correct me if I'm wrong anyone...
[Hero CDMA Android Development] c00ller:
I was curious of the same thing in the past, but urushiol said no, it's only for Sense ROMs.

Here are his responses..

http://xdaforums.com/showpost.php?p=7086870&postcount=148

and the next response has a link to a UV kernel for DD

[Hero CDMA Android Development] Papa Smurf151:
I don't think that will work unless someone packs it with the correct ramswap. Also not sure if u can use the HTC synaptic drivers for his rom. There is a reason he used the android drivers but hey who am I to say cause Im not that advanced yet
[Hero CDMA Android Development] chromiumleaf:
Great, thanks for correcting me quickly on that. I also don't know very much about kernels.
[Hero CDMA Android Development] c00ller:
I still want to know the voltages of the regular and UV versions. It has been asked several times but has yet to be answered. Hopefully someone can enlighten us!
[Hero CDMA Android Development] chefp:
Thanks for the awesome work! Running vUV 768mhz FreeMem with Fresh Hero 2.3.3 and it's stable.
[Hero CDMA Android Development] Androidious:
Yeah, ya'll are correct, I tried flashing the new kernel with DD 2.7, everything worked, except the touchscreen interface. So, it doesn't work with AOSP roms, yet... :) ONly with HTC Sense UI roms this new kernel will work with. Thanks anyway tho guys :P
[Hero CDMA Android Development] urushiol:
I'm not sure we know the actually voltages, but I believe the standard kernel uses "VID 7" and the UV kernel uses "VID 6", if anyone knows exactly what each VID on the HeroC is do enlighten us =). Building ZIPs atm.
[Hero CDMA Android Development] urushiol:
Darch thanks so much dude, this one works amazing, and I can verify it does have HTC synaptics. Uploading flashables in various varieties atm.
[Hero CDMA Android Development] Papa Smurf151:
Hey man check ur pm if u get a min. I sent u a msg
[Hero CDMA Android Development] MrGreg:
This has probably been answered before, but what are the advantages/disadvantages of the freememkiller tweak? I'd spend time reading through this thread but I gotta go chase after my 10 mo old right now :D
[Hero CDMA Android Development] urushiol:
PM sent!

All files uploaded and ready for testing, I have only tested the honeybun ones, they all work excellent, I'll let you all be the guinea pigs for the rest, do post feedback.

I have consolidated the kernels for freshrom with the ones using the stock 2.1 RUU ramdisk because after some checking, there are a few very tiny things different in the fresh ramdisk, but I don't think its going to mater. It MIGHT boot loop, if it does let me know and I'll swap out the ramdisks and upload a version for fresh.

Please everyone read the first post, its VERY important to flash the module remover if you have used one of the other darch kernels, otherwise you may end up having 2 ramzswap.ko modules.
[Hero CDMA Android Development] urushiol:
Its changing the same setting that the market app "Autokiller" changes, except its changing the default in the kernel. It will cause androids built in task killer to kill applications sooner, before the free memory gets low.
[Hero CDMA Android Development] foolforfood:
Just flashed on Fresh 2.3.3 and I forgot how happy I could be with just using my screen immediately! Thanks a million!
[Hero CDMA Android Development] urushiol:
Very nice, so standard is the one you flashed? I will mark it as tested working with fresh then!

And I agree, the lockscreen delay is vastly improved!
[Hero CDMA Android Development] foolforfood:
Yeah I flashed the standard 710 with free-mem. I do love this...

Edit: Could be placebo, but Swype seems more responsive with this, but I could be wrong.
[Hero CDMA Android Development] urushiol:
I would agree also =).

537mhz versions will be released tomorrow, I gotta head out for the night.

EDIT: Once vUV 2 is thoroughly tested I'll remove vUV from the first post, and redo v4, fixing the default frequency settings and memkiller settings. That way well have an standard voltage and an undervolted overclocking kernel with htc synaptics driver =D
[Hero CDMA Android Development] MrGreg:
For those that have used both v4 and vUV, do you notice any performance differences between the two? As I understand, the undervolting is a potential trade-off between battery life and performance. Thanks!
[Hero CDMA Android Development] oldjackbob:
There is no performance trade-off merely for undervolting. Either your device functions normally when undervolting, or you experience some sort of malfunction due to insufficient voltage. But there is no speed-related penalty as such for undervolting.

Edit: Performance, in the context that you mean it, is strictly dependent on cpu clock speed, and is completely independent of voltage.
[Hero CDMA Android Development] secbrad:
Installed Standard 710 Free mem. Everything seems to be working and yes the lock lag is gone.
[Hero CDMA Android Development] urushiol:
Anyone got this up on damagecontrol yet?
[Hero CDMA Android Development] azr6:
Just flashed the Darchkernel vUV2 710mhz kernal on my DamageControl v2.09.01 rom. So far so good...really moving along nicely.
[Hero CDMA Android Development] c00ller:
Ahh I remember VID's being mentioned in the "original" undervolting thread:

/* MSM7201A Levels 3-6 all correspond to 1.2V, level 7 corresponds to 1.325V. */
enum {
VDD_0 = 0,
VDD_1 = 1,
VDD_2 = 2,
VDD_3 = 3,
VDD_4 = 4,
VDD_5 = 5,
VDD_6 = 6,
VDD_7 = 7,
VDD_END
};

So 1.325V on the regular and 1.2V on the UV kernel. ~9.4% decrease in voltage; not too shabby! Although I can't understand why they made levels 3-6 ALL 1.2V, that seems kind of silly to me. I'm actually surprised that our CPUs even need 1.2V for 528 MHz. My undervolted Intel Core Duo processor can do ~1.09V @ 2.0 GHz. I know the Snapdragon is fabricated at a 65nm process and so is my old Intel CPU. Maybe the Hero CPU is done at 90nm. Oh wells, end of thinking out loud...

Also, big thanks to Darchstar and Urushiol for this awesome kernel :)
[Hero CDMA Android Development] urushiol:
Nice find c00ller, thats the post I remember, just didn't feel like digging for it. Your right that it hardly makes since to have vdd3-6 the same lol.

I have history of overclocking so I have a degree of familiarity with voltages, clocks and such. 1.325v runs my e8400 to 4ghz, so 528mhz seems quite lowly =).
[Hero CDMA Android Development] urushiol:
Humm can anyone confirm swap is working?

adb shell

free

"swap total" and "swap used" will be more than 0 if its working. Not working for me ATM, i'm on honeybun, 691mhz. humm, perhaps I forgot to include a swap partition last time I repartitioned my SDcard.... LOL.

EDIT: lolol, that was it, swap will never work without a swap partition!
[Hero CDMA Android Development] markus_del_marko:
the lockscreen lag is horrid for me on fresh 2.1.2 running free mem 710.
[Hero CDMA Android Development] urushiol:
Are you getting lag anywhere else? odd
[Hero CDMA Android Development] vashing:
I'm using vUV2 with memtweak on fresh 2.3.3 and having great results. My only issue is overheating. I'm running around 40-43 degrees just browsing the web. Not even using wifi.
[Hero CDMA Android Development] urushiol:
This was reported by some who used vUV also, I wonder if theres something going on that causes some phones to apply more voltage at VDD 6 than at VDD 7? My personal experience is just the opposite, I run about 2-5 degrees Celsius cooler on vUV2 than I do on v4.

Whats everyone else temps like?

vashing, what MHZ are you running?
[Hero CDMA Android Development] dopedroid:
Running nfinitefx45 stock Rom with vUV2 710m. No lock lag anymore which is awesome but I do get random hanging while trying to scroll through home screens. Ie I will try to flick the screen over and nothing will happen. I have to wait usually about 2 seconds or so then it will be fine. Running setcpu but it is at stock kernel speed 710.
[Hero CDMA Android Development] mozman:
Also running on nfinitefx45's Stock ROM. Just flashed 710 UV2. But have not noticed the lag you are getting.
[Hero CDMA Android Development] markus_del_marko:
a little lag when using awd launcher but after awhile it settles down. do you have to be using sense for this because i removed sense & im using the vanilla lockscreen from the fresh rom. is that why i still get the lockscreen lag?
[Hero CDMA Android Development] chromiumleaf:
Yes the new UV2 kernels with the HTC synaptics drivers are specifically for Sense UI. If you have removed/disabled SenseUI, then you should go back to the first UV kernel on AOSP synaptics.
[Hero CDMA Android Development] umrico:
Forgive me as I am slightly lost, which version am I flashing for the latest Fresh Rom? (2.3.3)

[Hero CDMA Android Development] xzjn9p:

[Hero CDMA Android Development] Sparticuz:
is there going to be an aosp version with the tweaks from cm?
[Hero CDMA Android Development] chromiumleaf:
You will want to flash one from the first set of links....the one that says it's compatible with nfinitefx45 STOCK, ZenHeroFX, and Fresh.

If it doesn't work on Fresh, post back and let us know so that urushiol can make separate .zips specifically for Fresh ROMs.
[Hero CDMA Android Development] vita10gy:
I'm getting force closes on incoming calls here, and nothing I do seems to be eliminating it.

I'm running Fresh 2.3.3.

I've tried:

v4 710, vUV 701 (mem tweak and not), and now the vUV2 710

restoring my nand backup

reflashing 2.3.3

wiping and then reflashing 2.3.3

wiping then reflashing 2.3.3 then flashing vuv2

The last thing I tried there is what I'm currently on, I could call it last night, but now it FC's every time, even after reboots.

Maybe I'm crazy, but I don't thing 2.3.3 does this by default, my menu-menu unlock has been disabled since installing these kernals, even if I restore nand, reflash, etc. I read somewhere all you have to do to get the normal kernel back on was restore/reflash 2.3.3, but it almost seems like parts of this kernel are still hanging around.

At any rate, what should I try? Is there a stand alone stock kernel I should flash? What Sense based ROM is giving people the least trouble with this?

Edit: Just tried the 691 version w/mem. Still FC on phone call. Also seems to have rendered the phone unusably slow.
[Hero CDMA Android Development] markus_del_marko:
which kernel would i use? i don't see one for a non sense rom?
[Hero CDMA Android Development] MrGreg:
I'm using Fresh 2.3.3 with vUV2. When you wake up the screen, I notice there is still a delay before the screen comes on. Is that to be expected?

When it does come on, it is responsive right away to input, so I can definitely see an improvement from vUV.
[Hero CDMA Android Development] urushiol:
Yes, I believe you will see the screen on delay even in stock 2.1 RUU kernel. If you play around with it for a bit you will see that if you lock the phone and then immediately unlock it the screen comes on almost instantly, its only if you let it set long enough to drop into sleep that you experience screen on delay time. I believe its simply the phone taking a sec to wake up.

If I could wake up that quick I would be thrilled!
[Hero CDMA Android Development] umrico:
TY! I totally overloocked the note that said nfinite, stock, zen and fresh...need more coffee too early :)
[Hero CDMA Android Development] cephraim:
UV2_710_M for stock working great on nfinite's ROM! Thanks!
[Hero CDMA Android Development] urushiol:
If I understand these things right as long as your using an HTC rom, not an AOSP rom, then the kernels using HTC synaptics should provide better performance regardless of what launcher you are using.

I will test later with ADW launcher, I've had issues with screen switch lag using ADW if you leave its settings at defualt, I'll mess around a bit let you know what seems to work best on my end.
[Hero CDMA Android Development] uf20wop:
i'm a noob at this overclocking thing

but as far as cpu temperatures goes, would they actually be lower than the stock kernel since the cpu is undervolted?
[Hero CDMA Android Development] umrico:
overloocked=overlooked...im a fail today :)
[Hero CDMA Android Development] urushiol:
Menu+menu unlock is controlled by /system/app/HtcLockscreen.apk and is disabled in all Fresh Roms for the heroc; it is not controlled by the kernel.

Nandroid restore overwrites the boot.img, so it is getting all the OC kernel out when you restore. You should be sure and wipe data, dalvik and ext though before restoring.

If you wipe everything, flash fresh 2.3.3 and NOTHING else, you get FC on incoming call? You should try redownloading the rom, or trying the stock 2.1 RUU from NfiniteFX45, or honeybun by beezy420 at androidcentral. There is no reason you should have FC on call on a clean wipe+flash with stock kernel unless the rom zip is borked or your phone is borked.
[Hero CDMA Android Development] Chrizmas:
I have been using one of the original UV roms (710mhz for Damage Control) for the last few days and have noticed significantly lower temperatures during long calls and data usage. The battery seems to last much longer for these as well.
[Hero CDMA Android Development] urushiol:
Just from using vUV2 for a day or so its been significantly cooler than v4 and about the same or slightly less than stock, especially during calls.
[Hero CDMA Android Development] Androidious:
Nice work...

I too have flashed this kernel over the top of my Fresh 2.1.2 (which was previously using the GodMode #89 kernel -- including the FCs for phone app and wifi tether stop problems). Since flashing this kernel, I must say, I haven't had ANY FCs and I was able to stop wifi tether without any issues.

VERY nice work guys! I'm even getting better MFLOPS benchmark results on this kernel than any other OC kernel I've tried! I'm getting about 2.9's lately now. Wish I could get up there with the 3's, but hey, beggars can't be choosers.

Nice job ya'lls! Very nice!

Thanks for the hard work!

I get incredible battery life with this kernel, but I don't seem to be able to receive phone calls. Calling people works but my phone doesn't ring when I have incoming calls. Doesn't ring for my sprint or my google voice number. I'm more than happy to try and help you debug what can I do?

(I've switch back to Toast-godmode oc kernel for now).

I'm running damageless 2.09.01.
[Hero CDMA Android Development] urushiol:
Can anyone else confirm this? This is an interesting problem, it think the damage kernel has the ramdisk from 2.08, perhaps we need 2 different versions for damage, damage 2.08 base, and damage 2.09 base?

Does anyone have any input on this or know for sure if 2.08 and 2.09 have any changes in ramdisk? I know this is mentioned but not confirmed here....

[Hero CDMA Android Development] Jus10o:
The damage 2.09 is just the newest sprint release. So the fresh kernel should work with damage 2.09. (if 2.08 doesnt)

Also someone reported on my OC kernel thread that the newest boot.img and the 2.08 one seemed to have the same ramdisk. I never actually looked.

If you need help with applying ramdisk and kernels, im always willing to help.
