Hello im just wondering if people are oc'ing their g1 since i be seeing people putting down speeds 384. If it is possible can you explain how to oc?
if you have a cyanogen build then it has scaled cpu which is better than overclocking imo, but all you need is root and an overclocking app from the market. i recommend set cpu or overclock widget. then you set it to your desired speeds and there you go.

Hi,
Sorry for the newbish question but I noticed Dalingren released new kernels today(02/23) and they all run at stock speeds. This is my first try with a new kernel and am running Froyo Customized 0.6.8. Just wondering what is the proper way to OC these new kernels? Do we have to use a SetCPU type program or is there a setting somewhere I am missing or a file that needs to be edited? I just don't want to break anything by doing it the "wrong" way.

Yes, you would need to use SetCPU to hit the higher clock speeds. I set my profile to vary between 800 and 1100 MHz OnDemand. I also set my "screen off" profile to vary between 300 and 600 MHz OnDemand so I reduce battery consumption when not using the NC.
It has worked well for me, been using that strategy for several weeks on the older version of the kernel. Just updated to the new one today and it still works great!
SetCPU is available in the Market for $1.99, but the developer makes it free to XDA members here: http://forum.xda-developers.com/showthread.php?t=505419
Its a really nice gesture to his fellow modders, so if it does what you need please consider buying it for $2.
this is a good way to go. I have been using it on my HTC Hero and now on the Nook.
It does not have profiles like SetCPU it is just clean and simple.

This is basically the same settings is use also. I set the lower threshold on my profile to 600. Go ahead and spend the $2 on setCPU. It's easy to set, and works well.

SetCPU for HC4-v2
I installed setCPU . But the top end limit is 600mhz. :-( I tried new kernals, old kernals... its always 600mHz.
What are the benefits of OC/UV (particularly for CM7)?
I know of improved performance due to OC, but what does UV do in regards to performance. Also, how does an OC/UV kernel compare to one without the option?
your processor doesn't need as much voltage as the stock settings--undervolting lets you save battery
personally i want to know.. do you have to UV to OC?

You can do either or both but don't have to do both. At some point UVing will cause a crash. Right before that point it can cause performance issues. See the link below for instructions on how to find an optimal UV level to maximize battery savings and performance.

OCing improves speed but can also cause stability issues. For a captivate this usually isn't a problem until you get past 1.2 ghz. After that, it depends on the kernel but I have yet to find a kernel that is completely stable past 1.2 ghz under stressful conditions. Samsung designed the processor to handle 1.2 ghz and in theory it can go up to at least 1.6.
Like everyone before me has said, OC will make your processor work more (which will eat up more battery, and send the temps a bit higher).
UV is a way to "fix" that problem by controlling the voltage used by each Mhz/Ghz range. The mini guide that QuarkGluonSoup posted is a great way to start off.
Most Captivates start have random errors past 1.2Ghz, but the highest I've seen (stable) are 1.4Ghz.

Odd as it sounds, my battery life on CM7 is close to 50% better when it is OC'ed to 1.2 ghz and UV'ed than it was on the froyo ROMs under the same conditions.
That really is odd :S I think I'll try it myself.
I'm running Overcome Hermes 2.0.1 on an AT&T GSM Galaxy Tab, and I'm using SetCPU for both overclocking and voltage control. Seems like everyone has a Galaxy Tab that can be overclocked to 1.4Ghz except me. I want to join the party.
When I overclock to 1.4Ghz, for the most part everything runs fine, but when the CPU really gets stressed I get crashes. This has forced me to disable the 1.4Ghz step. This is despite the fact that my CPU performs like a champ otherwise, and I've managed to undervolt all the steps except for 1.2Ghz by quite a bit.
Is there a way for me to give the 1.4Ghz step a slight voltage bump to improve stability? SetCPU doesn't seem to offer an overvolt option, is there a way to edit a file and manually change the voltage? Where are these voltages for the overclock steps being read from in the first place?

If you do a quick search, there's a voltage control app floating around these forums.. voltage_control_gt.apk i think..
Donate version of voltage control supports over volting. Bear in mind increasing boltage doesnt necessarily mean more stabilty at certain clock speed.
But it does mean a higher chance of ruining your motherboard.
i am fairly new to rooting phones. i just installed cyanogen 7 on my htc hero. works much faster than the stock. had heard that you can overclock the cpu. i downloaded CPUmaster free and lets me clock cpu to 768MHz. have been doing some research on this and have come across a few things. so really just one question; 1) what is the fastest you can clock the cpu with it still being stable?
help with this would be very much appreciated!
Depends on a variety of factors and every Hero is different. Depends on the ROM your running, kernel, etc. You can play around with capped and uncapped kernels but no one can really give you an exact # but you..u'll just have to try tinkering with the settings. If your wise you will just select one of the governors located in Cyanogenmod Settings. I prefer SmartassV2,min. 362 max 691 its efficient and takes care of everything while prolonging the life of your battery. Also remember that overclocking for an extended period of time will overheat your phone and could cause damage, so keep an eye on the core temp while playing with ur cpu settings.

Some phones can't take more than 691, some can handle 768. I have found, for my phone, that 245/710 works great for me. I can see a marked improvement in snappiness at 710 over 691, but not really much at higher frequencies.
I used to use OnDemand as my scheduler, but with the newer .35 kernel I have liked the SmartassV2; I don't have any issues with music cutting out like i would with smartass or interactive. CM7, or most any of the roms built off of that, have the option in CM Settings to adjust both the frequency and governor so you don't need to install a 3rd party app to do so (it's under the "performance" heading). I also like to go into the spare parts app and set my animations to fast; that's just me though. I think the new CM7 builds have Jaybob's .35 kernel now instead of the .29. I have not seen an uncapped kernel that goes beyond 768 in a long time. There was one that jasonmaloney compiled that did 806 (I think) but that was pulled by him as it isn't good for the phone. just test it out and see what you like with what you have installed on your phone. Every phone is different even though they are the same.
What kind of success/failure are people having with overclocking and undervolting?
I'm doing this through ROM Toolbox Pro. Is there a better way? I'm a n00b with some of this stuff.
I have the phone overclocked to 1200mhz and all cpu levels are undervolted by 100mV.
Im doing so to get more performance, and better battery life. Just wondering what settings everyone else is using.
Also I'm using CM 10.1, with the BlueMint Theme.

Every phone has different limits. It's just like PC overclocking, no two CPU/MB/RAM combos are exactly the same. In general most of Captivates will handle 1200 step OC with default voltages. Not too many will handle 120% live OC though. It doesn't matter what tool you use to OC. All tools try to play with the same kernel settings. In my experience UV saves very little battery but increases significantly the chances to get stability issues. This is why I never play with UV. My particular phone can do 1400 step OC or 1200 live OC with 1350mV. I run it on 1200 step OC @ default. Also, keep in mind that different ROMs/kernels give different OC results.
RE: undervolt
I agree with Val D that undervolting will not show any significant benefits. Overvolting has helped me with stability while overclocking. I use the free Voltage Control app for voltages, or the free NStools app. Rom Toolbox is a great app too- I use it for many other things- stick with what works for you. Currently I am running at 1200Mhz step, at 120% Live OverClock to get CPU up to 1440Mhz, and ARM voltage of 1350mV at that 1200Mhz step. Rock solid. Battery life suffers a bit, but I run this way for gaming. Day-to-day regular usage I just set to 1400Mhz step and no Live OC, default voltages. I have run fine in the past at 1500Mhz, no Live OC. Overclocking the CPU tends to make my phone a bit snappier and more responsive. A big battery drain that affects my phone is an app such as Gmail running in the background, or leaving wifi enabled when not in use. Setting the phone to Airplane mode has been a big battery helper too (I do not make any voice calls on this phone anymore). Governor and scheduler setting can also have a big effect on battery life. I searched for this post I made a while back that linked to two great articles on studies of battery life and voltages, and ended up reading through them again:

Great information. Edit: just figured out how to link articles in my signature.
Thanks guys. I know each one over clocks differently. Just looking for some rough outlines. Thanks for the links. I'll be reading up on those. I have extensive computer over clocking experience, but on e phone its a whole new ball game. Basically trying to make this phone last longer.
I'll have to learn what live OCing is vs step OCing.
Thanks again!

I just do 1200mhz OC using CyanogenMod 10.1 - the option is in the performance menu. So far no problems.

Awesome. Didn't even realize that as there. I've been using ROM Toolbox to OC to 1200MHz.

overclocking to 1200 mhz will made any difference ?

I really didn't notice much of a difference in speed or responsiveness using CM 10.1.
