Undervolt and underclock?...

Are they the same thing?
Sent from my ADR6300 using Tapatalk

no....underclock means to lower the clockspeed (from 1ghz to 900 mhz fkr example) and undervolt means to lower the voltage being delivered to the cpu at a given clockspeed.....you as the user can freely undervolt using setcpu but the kernel chef is the only one who can undervolt a kernel

Thanks!
Ok, 4 questions:
1)Does undervolting slightly affect the performance of the phone? If so, in what way?
2) Which kernel is better on the battery? Kingclick, our hydra kernel?
3) does it make sense to overclock slightly on an undervolted kernel.
4) which roms are most compatible with each kernel if there is a compatibility issue?

1. undervolting improves battery
2. hydra is better on principle
3. overclocking is never necessary....overclocking isnt needed at 1ghz, but if you insist in overclock, 1.113 ghz is good....or 1.15 but i wouldnylt reccommend 1.2
4. all sense roms work with custom kernels

I'm pretty sold on skyraider. But It s packaged with kingx. Have you tried hydra with skyraider? Does it perform better than king x and would you recommend it?

So if I have a stock rooted 2.2 Incredible and just want to save some battery, can I just drop a kernel in place and it will "just work" ? I have SetCPU lowering the clock when screen is off, would this be better?
thanks!

If I was you, I would flash your kernel of choice (mine is hydra ssuv v0.5) and definitely lower the screen off profile....and use a good Rom too...speed isn't always in the kernel you use, its in the Rom too...that's why I don't overlook....
And also, unpack and quadrant are just bragging rites, nothing more nothing less

[Q] Overclockable Scense kernals?????

Alright im having a real hard time with this. I have a scense rom and want to know if there are any overclockable kernals for it. I have not been able to get a strait answer on this and hope someone could help me. If there are what is a good one for battery life and charge time??

Ziggys471.com. they can be ocd an have good battery on z roms. What rom are you runnin.

im running Inc Rom 1.6 and if i do believe i still had a problem with the ziggy kernals but i will try again due to my google account getting messed up from the playstation hacking that occured. since then all my emails went haywire.

i meant to say i factory reset my phone so i didnt save the ziggy kernal but i think it still had graphical glitch bars when i tried it.

Actually it wasnt overclockable thats why i didnt keep it its the same as all sence kernals. This is a bummer because i like sence roms for the camera and they have no overclocking kernals that i found yet

Can u overclock the dinc and if u can how do u do it. Thanks in advance
Sent from my ADR6300 using XDA App

There are a couple of ways to overclock the dInc, but it depends on which kernel you use and what ROM you have. For froyo, Ziggy's are probably the best. Tiamat is very nice for AOSP gingerbread. An app called SetCPU can be found for free to XDA members on here. Just Google it. There's also a couple free apps on the market. If you're still using froyo, I suggest only Ziggy's because his will allow you to use scripts to change the speed and the voltage at every step and he lays it all out very nicely, including samples that you can just edit and mix together. The benefit of the script is it doesn't use system resources like an app would.
Pushing it to 1.153 should be hard with most kernels so long as they aren't undervolted. Some devices are stable at 1.19 and some even higher. Few will exceed 1.19 though. Overclocking and tweaking kernels can be an interesting thing. Most kernels with a sysfs or ramdisk will allow some kind of scripting. Definitely check out Chad's IncrediControl.

Another good kernel for ASOP Roms (both gingerbread and Froyo) is Incredikernel. Always check and see if the Rom you want to overclockable and if it doesn't say in the OP ask the creator of the Rom, they'd be happy to help you out. Also, make sure you know the correct way to flash a kernel. It's the same way you flash a Rom, so it shouldn't give you any trouble. Happy Flashing and Overclocking!

Thank-you guys. I'm using kingdom rewind 3d so ill ask joelz if it overclockable and if not...so be it. Once again thanks for the replies

None of the gingersense ROM's will be overclockable until HTC releases the kernel source. Which will happen sometime after we get the OTA. So it's either Froyo Sense or AOSP Gingerbread if you have to overclock.

Not sure that's true. I'm overclocking the kernel on this Tbolt and there's no source released for it either.

It's not available on XDA anymore. I'm actually running Ziggy's kernel on it now. I'm gonna change my sig in a second.

I have found if the ROM is developed well enough, overclocking is not needed. You wont see too many benefits.

On 3G, not really. On fast WiFi or LTE, yes. That's when you're looking at situations where the device isn't waiting for data. That's where you'll see the bigger benefits of overclocking.

Kind of off topic, but what benchmarks (apps) are you guys using to determine the effectiveness of your overclock?

Doesn't really matter. Quadrant, linpack... you're comparing same setup to same setup. An overclock on one isn't going to yield comparatively different results when compared to any other... at least it SHOULDN'T.

This may be a stupid question...I am having trouble with all the kernels and ROMs determining what is a safe OC for my DInc. I am flashing CM7.0.3 now and I read that it's got OC built-in. I just wanted to OC to whatever is definitely safe. Is that 1.113 GHz or 1.153 GHz as indicated earlier in the thread?
Or is it something I'm going to have test on my device to see if it exhibits a specific symptom?

Your milage may vary, but usually when things become unstable you can't really naviagte to anything and you get a bunch of reboots, or so it has been in my case, but again YMMV.

Every kernel dev has his own choices for kernel voltage and that's usually the single biggest variable in what stable will be. 1.113 should be stable for most devices though.

Thanks for the responses. I tried 1.113 on CM7 (7.0.3) on my Incredible and I started getting constant reboots. I put it back to 998. Maybe I'll try another setting later.

[Q] Now that we have root...

......what ROMS work and how do we overclock?

Unless something has changed, all roms should work (that are made for the evo) and use setcpu to overclock. Please use the search button next time.

eh...I am coming from a DROID2 and setcpu is not the best way. I actually did a google search and only got info on the fact that someone did overclock, but nothing new to support his method was successfully Alpha'd....I was using jrummy's DROID2overclock before, just wondered if I missed anything in my google search about a similar app anyone has made for an EVO..
But thanks for the ROM info

Yea I used setcpu for the time I had my evo (a year) and it never gave me any problems. Just have "set on boot" unchecked to see if that clock speed is stable. I don't think there is an app made specifically for the evo but by all means, Google "evo overclock app" or something along those lines. Btw, all phones will not react the same to apps on the market. Just keep that in mind please

I guess what I am getting at is, on my D2 I could overclock to 1.1, 1.2, 1.3ghz but setcpu doesn't have a scaler to up my ghz(unless I am completely blind, which happens from time to time). I am currently stuck at the stock EVO clock speed.
What I am trying to figure out is how to overclock to 1.2ghz.
Thanks for the assist guys!

You need a kernel that has oc'ing capabilities. Depends on which rom you run, some only use certain kernels
We're comin from a pure power source.

If your using a sense Rom Lithid's Freedom kernel is pretty amazing and supports Overclocking and underclocking, as well as voltage tweaks that make your battery life awesome.

Personally, I don't buy into overclocking. It's really just not necessary with the EVO

Undervolting is done with kernels that support HAVS, setcpu on the other hand is for adjusting CPU speed frequencies, to undervolt you need either vipermod or incredicontrol with a kernel that supports undervolting and/ or overvolting.

Isc kernel

So im curious is there an overclockable kernel for ics that i can use with set cpu. All i see are stock kernels. Are we waiting for more development on kernels? On gb i could over clock to 1.7 which was awesome.

Doesnt work with cm9,miui, and apperently aokp, since im on aokp and it says kernal not available. Custom kernels would be awesome right now

To begin with we don't have the source. It's not as simple as splitting the zImage and typing in some numbers. Also, there's very little demand for OC'd kernels on this phone. Most people that OC do it to increase performance, reduce lag, play games, and a few other things. Basically they do it for a reason. The ones that do it just because or so they can show it off to their friends are a very small group. Since the majority don't feel overclocking is necessary on this phone there won't be too many OC'd kernels even when we get the source.
