Does anybody know if it's safe to use SetCPU on the D2? The processor is fast enough. I'd just like to see if i can stretch the battery by underclocking it while the screen is off as I've read is commonplace on other phones. Thanks.
I would definitely like to know also cause if you can I would root right away

I rooted yesterday and setCPU was one of the first apps I installed - just for underclocking when asleep! Seems to have worked fine, no problems yet.
Yea I autodetected speeds and it seems fine. It won't allow you to overclock yet until we are able to either get a new kernel module to do it or a full kernel (bit off still, even droid x can't do that yet). I underclock when screen is off and that works just fine
ok. thanks. i've been running it for about 12 hours now to underclock with the screen off and so far, no issues. this phone is getting better by the day.
I've used SetCPU to underclock while the screen is off. My battery life is much better than before. I've also removed some of the bloat.

I too have been using SetCPU to underclock when the screen is off or when I'm in class. I haven't had any problems yet.
It's the first app that I've paid for but thats just because I'm cheap, but that's only because I'm a broke college student.
I'm running SetCPU 2.02 no problems. I'm actually running my phone underclocked to 800 and it's running fine. Screen off is set to 600.
The latest jt kernels and people's derivatives of them have not been playing well with SetCPU on my phone. It has been freezing up. Any advice on a certain version I should use or maybe settings issue?
Check to make sure profiles is not enabled. Using them will make your phone freeze and or not come back awake.
Also make sure your on conservative and not ondemand. I hear the ondemand is still being a little buggy.
Currently I'm running jt's oc kernel at 1.3ghz stable. Setcpu is on conservative and I have zero problems, only when I change to another setting does it have problems.
At this time what could I use setcpu for besides overclocking?
theres no point in using setcpu with jts kernels as theyre not overclocked...unless u need to UNDERclock for some reason

I'm using setcpu to underclock my phone (for bettery battery life), and I set up a few profiles to drop the speed down when the screen is off (100 min, 200 max), and when the battery is below a certain amount (100 min, 400 max), and it seems to be running fine. No freezes, no problem waking up.

JT doesn't have an OC kernel out. If you're using nemesis's OTB OC kernel then you shouldn't be using SetCPU, you should be using Voltage Control from market. SetCPU has caused some issues. This will give you orange CWM but you can always Odin the red one.
im running the extreme1.92x kernel oc'd at 1.4 but not sure about the best setup to save battery. i made one profile for charging i put in on max. not sure what to do with the advanced tab settings.
Profiles are really dependent on the user and their needs. The one piece of advice I can give you is to make sure you have a profile set up in case your phone starts to over heat. An OC'ed phone maxed during a charge may get quite toasty.
any suggestions?
Imo dont o/c. Let the kernel operate the way it is setup. O/c cause reboots, phone heating up, and freezes.

I'm running Adrynalyne's 4.4.7 kernel and use the following and get really good battery life with no overheating and no lag. I don't do a screen of profile because the governor seems to handle that pretty well.
Normal 1024 max 245 min-Smartass governor
Profiles:
Battery < 25% 768 max 245 min-On demand Governor
Charging 1280 Max 245 min-Smartass governor

Does that actually work?
I thought you had to choose a default governor and setup profiles accordingly.
I didn't know you could setup profiles with a governor that wasn't active or chosen on boot.
the thunderbolt is so fast already theres really no need to over clock. i left it at stock for normal, toned down to 768 when <30% battery and down to 368 when screen off. its a little slow for about half a second when waking up but the battery life is amazing. i can make it through a whole day without charging with moderate use. also running ziggys bfs kernel on virusrom and that added a ton of speed. way better than overclocking that drains your battery
im not asking about overclocking or profiles, just want to know about advanced settings. everything is set to default -1.

What Rom are you using?
Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.024GHz max with ondemand governor and most importantly SIO Scheduler. Try these n you will have amazing performance and better battery life. Let me know you opinions

No matter how precise I click, I can't get SetCPU to set 1024mhz. Closest I can get is 1036. What gives? lol

Haha, I couldn't tell if you were being serious or not but each kernel has speeds at different increments. 1036 will probably be as close as you can get to 1024.

You can use Wikipedia for the scheduler info. Once you look into it you'll know why I didn't wanna type all those details in here from my phone. Lol, but yeah set that to SIO, Take off ENABLE data always on. N you should be better let me know.

Go to manage applications and clear data from set CPU and when u go back in to set CPU you will have to hit auto detect n if ur kernel has that frequency you'll be able to click it.

Honestly, I'm down to 1512. A notch above that proved unstable as far as I can tell. I can run benchmarks fine upwards of ~1800, but I'll get random force closes and boot loops if left for any extended period of time. Also have issues with display not coming back on (menu lights and led backlight work, but no image). The stability test app is pretty much worthless too. Let it run for 6 hrs no errors. When I turned it off, BAM restart.
So what is your max, truly stable, OC?

edit: just for archival's sake, using Anthrax-CDMA-Sense (v1216) with Scott's 2.08.651.2 Stock Rooted ROM.
That's interesting...
I'm using the same Kernel with Scott's 'senseless' ROM and I have my clock set to 1.836 with no issues.
I'm no expert but have you tried using a super wipe (or just manually wiping everything including system) and reflashing?

My first 3D was pretty stable at 1.94 but when it started getting the black screen of death I got it replaced through sprint. The Refurbed one they gave me (the one I have now) freezes if I go to 1.6..
I used to do 1.94 but it gave me random reboots (nothing fatal)
I stick to 1.5 smartass when the battery is greater than 50%, then 1.2 smartass, and .8 conservative at 15%.
On charge it's 1.7GHz lagfree
Depends on your CPU, they all arn't created equal. I'm stable at 1.9 GHz with no reboots. I'd say that 1.5 is a good mark, seeing as the HTC Rezound has the exact same CPU as the Evo 3D, just clocked to 1.5 instead of 1.2.

This is interesting. I bet the CPUs, while manufacturing wise are identical, are chosen based on thier bin level for the different devices.
After writing this post I cleared Dalvik cache and switched my kernel to RCmix-evo3d-v7. I ran it at 1.62 or something like that while I was running around Christmas shopping, so it had heavy use. Google nav, lots of phone calls, texts, Pandora, etc with zero issues (especially that display issue I mentioned is gone, thank god). After getting home I was so impressed with it that i stepped it up to 1.782, and we'll see about that, although I'm not holding my breath.
Basically I learned that your overclocking potential (or maybe more accurately system stability regardless of overclocking) is greatly influenced by your kernel.
Akasa Fox, mind sharing your kernel version, ROM and version, and hboot and any other potentially relevant information I may be forgetting? I'm impressed with your performance.

I like this approach of different clocks and governers based on bat level. Is this a pro feature of the Antutu app?

The kernel does have a decent bit to do with your max OC, but it also has to do with the CPU you have and if it was made on a good day at the foundry or not and how good a section of the silicon it came from.
I used to run RC Mix kernels before Chad was around, but those kernels always ran MUCH hotter. When playing a game my phone would literally be almost too hot to touch. Chad's Anthrax kernels have always been cool and after playing a game for a while (same game, same amount of time) the phone is just a bit warm. So you may be able to go farther with an OC on RC Mix kernels, but your phone's lifetime for its processor is going to be a whole lot less. At the temp it was hitting id bet it is well above its max rated temperature level and degrading the processor substantially.
Some people may not be able to OC far, but how far can you undervolt? Many times those who cannot OC very high can undervolt like crazy (me included) and those who can OC much higher than most also cannot run really low voltage levels. My phone is 100% stable @ 192MHz on only 700mv. Thats the lowest Chad allows, Id love to see if I can be stable even lower. I am also 100% stable @ 1188MHz (HTC Stock) with only 987.5mv. But the most I have ever been able to overclock stably (even with RC Mix kernel) was 1.6GHz, with the max benchable being 1.72GHz. Any higher and the phone insta locks up and reboots. No matter what voltage.
Hm, that's a good point. I'd like to push the undervolt limits as well to see what its got. That anthrax kernel I mentioned in the first post was terribly unstable for me, but maybe I should give it another shot after researching the super wipe method mentioned a few posts up. Is there a version of his kernel that everyone is having good luck with? Or is the latest one the best?
Also, I don't see voltage options in the antutu program. What are you using for your oc/uv utility?
Thanks.

His latest 100% Qualcomm based kernel is incredibly smooth. 100% stable for me. I'm giving this kernel a lot of praise considering I used to have crazy reboots and lockups on the older anthrax kernels.

Weird. Well, I will give it another shot before writing him off. I'm a noob so its entirely possible and probable that I did something wrong.
I found setcpu last night, but I didn't see any uv options. Does rcmix not allow for it?

My phone won't overclock for ****. At first it would do good and I could get around 1.7-1.8, now when I try anything after superwipe and wiping through nand, I can't get the thing to post at 1.5 and remain stable without lockups/freezing and slowdowns. The phone even has trouble at stock now. I haven't traded it in for obvious no s off reason.
1.78 GHz. I can do 1.83 but not very stable.
1.782 runs all day locked at that speed but I usually run bcblend kernel @ 1.512 max 194 min. Ondemand.

I know it was Virus' InfectedROM (Before the nightly), Software 2.08.651.2, HBoot 1.5 (HTC Unlock.) [Edit]: I'm almost certain the Kernel I used was Tiamat, hard to remember though, seeing as I traded out performance for battery life by switching to viper ages ago. (And that i'm a flashaholic )
im @ 49 hours uptime on RLS4 of my new kenel @ 1.94GHz IntelliAnthrax
..no RLS4 is not public yet -- testers will have it in 1-2 days
What do you guys think is better smartassv2 or ondemand? I usually use smartassv2 but im not sure with the rezound.
I'm using ondemand and its been perfect for me. no rebooted and great battery life.
I flashed incredikernel 6 the day it was released weeks ago.
I use on-demand, I have not had a single reboot/bootloop etc yet & the battery life is super.
I use on demand with the stock Kernel (using cleanrom 3.5). I drop the cpu down to about 1.ghz and set a profile for on demand between 192 and 760 something when the screen is off. I only dropped about 3 percent a few nights ago while sleeping (6.5 hours roughly). (the phone doesn't go into sleep mode and I dont have a battery saver). I don't get that with my heavy usage, but that is a big plus.
Where do you guys get the download for ondemand? Back in the day when I had the OG Droid, everyone used SetCPU. Doesn't seem to be the app of choice any more to set frequencies. I can't find ondemand (or smartass for that matter) in the market. ANy suggestions?
I had been using ondemand up until a few days ago. The last couple days I have been using interactive, and it seems like both battery life and performance are somewhat better, although I have no hard numbers to support this, and I have really random usage.

They're features on the kernel. When you install the kernel you'll be able to check which one you wanna use from the app. (SetCPU may be good, but it seems the apps of choice on the Rezound are AnTuTu or Systems Tuner Pro, I use AnTuTU.)
Or if you use incredikernel the app incredicontrol goes along with it perfectly and is 100% totally stable for me. I have tried every kernel there is both GB and ICS on my phone and incredikernel and the stock kernel are the only ones that will run stability test scaling stability test all night long without bootlooping.

Thank you so much for the reply. I am just sticking with the stock Kernal for now, but I was interested in undervolting the kernal while it's in sleep mode and while charging to see if I can save battery life. I just tried SetCPU, but was not pleased with the constant SU pop ups. It was keeping my screen awake. I think I'll five AnTuTu a shot.
If I ever load a custom kernal, I'll know what to keep an eye out for.
I have completely given up on undervolting at this point, I never once saw a noticeable increase in battery life but I definitely ended up with a less stable phone.........

What we need are more custom kernels.
I have undervolted (Incredikernel with Incredicontrol) and it's quite stable and the battery life is pretty good. I can get 12 - 16 hours with the stock battery with medium usage (texting, browsing).
Interstingly, it was 10 - 12 with OnDemand. Interactive seems to be better.

Have you ever tried leaving all the settings exactly the same and NOT undervolting??
I would be willing to bet the battery life would be almost identical.
CPU Tuner is awesome also. Might be the best.

Actually, yes. It did make a difference. Not as significant as on the Incredible, although that may be a difference in HAVS vs SVS.
But what works for one may not work for all.
