Cm7 overclocking??? - EVO 4G Q&A, Help & Troubleshooting

Is there a kernel I can flash that will allow me to overclock past 1113 for cm7? I'm not worried about battery,HDMI or wimax. Thanks in advance.
Sent from my home phone.

Also do I use the set CPU app or the one built into cm7?

I am using SavagedZen (first link), and can overclock to 1190, which is about the highest I have seen for overclocking, the other kernel that is fairly popular for CM7 is Tiamat (second link) and I believe that they support overclocking also (not sure how much though).
If you are using a smartass governor, you will want to use the built in overclocking feature of CM7, but you will probably need SetCPU and profiles for the other governors

Set cpu help

Okay so I disabled the battery tweak and just started using set cpu. My set cpu doesn't have a lot of profiles or options even. I would like to know if someone could point me in the right direction. Thanks in advance.

The profiles are user defined so if you havent made any, there won't be any to choose from. What are you trying to do?
I'm trying to make more profiles, or smarter ones. I wanna see what everyone else has..

Honestly, I don't even use profiles anymore, I just let HAVS do its thing. When I did use them, I used screen off @245 and low batt set to 15% @768.
A HAVS kernel?

Yep. When my phone sleeps, it really SLEEPS. I can go all night without losing a single % point.
This site has two profiles setup for SetCPU

I'm curious about what kernel to use. Kings#11 sucked, netarchy cfs was bad..and seems like the only one tolerable was stock but I need to have good battery power..I'm currently using ziggy471

I am getting great battery life with MikFroyo and stock kernel. If you use a HAVS kernel be careful overclocking it, increasing CPU speed with decreased voltage from the HAVS can harm your phone
Sent from my PC36100 using XDA App
I'm getting annoyed with these kernels. So far the only ones that work are ziggy471 and stock 17. I really want to switch to myns two point two rls 5. Problem with that is I don't want to upgrade my radio and lose something. So how do I upgrade without fixing the radios?
Sent from my PC36100 using XDA App
I updated my radios and then downgraded my PRI back to 1.77, its easy and works great.

Overclock and kernel question

I would like to boost my performance a little bit either through another kernel or overclocking or both. How do you overclock the Dinc, and do some kernels overclock better than others? Thanks for any help.
Certain kernels have higher overclocking ceilings than others but none are "better", per se, for overclocking. Check out setCPU or CM7 has overclocking preferences built in.

Ok cool.
I am running cm7 but also have setcpu, is one preferred over the other? And as far as overclocking, do you just start increasing the speed slowly until you get it where you want or it becomes unstable?
Sent from my ADR6300 using XDA App
I would just use the built in OC of CM7, I've heard that using both can cause conflicts. And yes, just bump up your frequency bit by bit and if you start getting reboots or freezes, dial it back. For AOSP kernels, I've founds incredikernel to work really well, then invisiblek, then tiamat. Though incredikernel does have a lower OC ceiling than the others.

"kernel manager pro" in the market may also be useful for you. It keeps up to date on which kernels work specifically for your device and you can flash from the app. I'm currently using Tiamat 4.0.2. It will clock to 1228MHz

SetCPU Issues

I'm having problems with the so called "sleep of death".
I make all my profiles and leave the defaults for conservative. Minimum is set to 200mhz and max for screen off is 600.
It seems like no matter what I set the clocks to my phone never wakes up from sleep. I have to pull the battery to turn it back on.
Running SFR1.1.1.

Edit
Is it the screen off profile?
If you're using the included kernel for SRF 1.1.1 don't use a screen off profile, set it to conservative, and minimum cpu at 200mhz. It should be fine with those settings.
Its on the first page of the SRF thread.

Switch to paid version of Voltage Control. It's optimized for us now.
Having issues with setcpu freezing up my phone even with no profiles.
If voltage control is optimized for epics I may buy it. Underclocking really boosts battery life.

Are you set to conservative?

All profiles were set to conservative, yes.

What was your lowest freq set to? Some phones don't like 200 at all
Sent from my armed and operational battle station.
Wasn't Conservative deemed buggy for the Epic? And ondemand was the better option?
The new twilight kernel, which is included in SRF 1.1.1 is fine with conservative.
There is a free version of voltage control too. Uninstall set cpu and try that first and see how that works for you... if that doesn't help, maybe you should flash a different kernel.

Yup. I believe this is posted a few times on the ACS thread. Go with Genocide or Vision. Now on demand will drop below 200 even if its set at your minimum but may very well still work.

Someone correct me if I am wrong, but I thbought there were also problems by using profiles at all.
Have you tried getting rid of the profiles? (After backing them up, of course)
Sent from my SPH-D700 using XDA Premium App
I use the Vision kernel with SetCPU to ondemand with NO issues at all I had profiles enabled at one point but it seemed redundant because I had it set to ondemand. If you have it set to anything other than ondemand then I can see using profiles.

Cpu tweaks

What is the best app out there for tweaking cpu and stuff? Tegrak, extweaks, setcpu or what?

I've used antutu CPU master in the past but nowadays the ROMs I use have that function built in so there's no need for a 3rd party app. Anyway, I liked antutu bcuz u can tweak the scheduler as well as the CPU and governor.

Extweaks is pretty good. No-frills gets the basic job done.

Well. Depending on what ROM I'm running. I use the following
SetCPU
Voltage Control
Pimp my CPU
Tegrak Ultimate
ExTweaks
Out of all of them. ExTweaks has the most options but it is kernel specific. For just undervolting and adjusting the clock speed and governor and such I personally use SetCPU if the kernel supports undervolting and if it doesn't I use Tegrak Ultimate.

I can't get setcpu to work on stock. Causes my phone to reboot as soon as it goes to sleep. I overclock while in sleep mode but nothing crazy.

Tegrak Ultimate gets my vote.
I've used tegrak, setcpu, and voltage control. I like the voltage control interface better.

Set new cpufrequency on shell(any number)?

Can I set new frequency by shell?
Currenty I'm using sysfs(voltage control, vdd level) enabled kernel.
I want to set clock that isn't not on the table.
(most overclock apps like SetCPU only can select clock from table.)
Uxcl S6 and most kernel had 1516800(stock) instead 1476900(BeastMode) for 1.5GHz it's hard to undervolt.
Even freezes 1225 vdd. (1476900 stables on 1200 vdd.)
Want to set 1476900 on uxcl or virtuous kernel etc. without modding kernel's table don't have source for that

I think the frequency needs to be supported by the kernel. I don't know.
