My apologies if this has been answered but I haven't been able to find it ...
I'm running AvaFroyo V7 ROM on my rooted EVO, and installed SetCPU. Things are definitely faster. But it appears SetCPU only allows me to UNDERCLOCK (to save battery life, etc.).
Can SetCPU *not* overclock? What am I missing here ...
Thanks in advance!,
Jon
Overclocking has to be enabled in your kernel before you can set it ine set cpu.
It will allow you to overclock if you are using a custom kernel that is capable of the higher frequencies.

Thanks Steve!
Any recommendations ....?
I personally prefer Netarchy CFS 4.1.9.1 and I overclock to 1.19. King makes good kernels too..

Thanks, much appreciated!
Btw, what kind of clock speeds are you able to attain with those kernels?
-- Jon
Most of Kings and Netarchy's kernels can overclock to 1.26 but some CPUs become unstable at those frequencies. Mine runs real nice and safe at 1.19
Duh, my brain was on auto-pilot, didn't see the 1.19 in your previous post.
Thanks a bunch man!
Releasing my kernel ver10 which has NO OVERCLOCKING but has Undervolting. I'm pretty happy with the speed of Tegra 2 and I think there are a few advantages in keeping our speed in stock. Advantages IMO are as follows
1. Better Battery life
2. Less heat
3. Stability (unless it is too undervolted)
Update 4/25/11
Releasing PimpMyGtab and My latest kernel ver 11 with no Overclocking, just stock Speeds..Underclock using PimpMyGtab
Here is the link on how to use PimpMyGtab
http://forum.xda-developers.com/showthread.php?t=1018411
** If you get a scaling_governor error upon starting PimpmyGtab. It means you need to set your governor by going to Terminal and typing echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor or by installing CPU Master and choosing powersave in governor.
BIG THANKS TO CPASJUSTE for the app and kernel codes.
BTW, If you like my work, don't hesitate to buy me a beer
If you ike PimpMyGtab, make sure you buy PimpMyCPU (Source) from the market by Cpasjuste
Thanks.
Nice. I'm not a fan of overclocking, however undervolting DOES interest me. As soon as I get an opportunity, I may try this out.
Curious, what's the stock voltage?
OK, LMK how it goes.

stock - 750mv - 1000mv
Well I tried it out real quick, it works well (haven't verified battery life changes), but I had some questions:
Is there anyway to set the voltages explicitly? SetCPU didn't work with it (couldn't even change the freq or scaling governor).
I forgot your kernel doesn't support mounting the internal SD over USB. Is that something that will be fixed soon (assuming it's actually broken)?
I won't have my tab for a few weeks, sending it in for warranty replacement. So I won't be able to do further testing.
Thanks for the great work!
Hello clemsyn,
Try it out and battery life is soooooo gooood ... lot better than the OC 1.5GHZ one, of cause it run slower, but it's where i came to ask, if you could release one with the same voltage but for 1.2Ghz (which i guess it's stock speed)?
Many thanks for your hard work

OK here it is...this is basically stock voltage with OC to 1.2 ghz.
Thanks. Right now I'm tryingout the 700-900. Quadrant dropped from 2350 to 2150 going from ver9 to the UV.
I've been using the original kernel posted in this thread for a little while now. It has some strange slowdowns when the tablet first boots (from being powered off), but after that it runs great. Have not had any freezes, so it seems stable. Quadrant scores are ~ 2300.

Hmmm, for some reason my pad won't run any of your Ginger undervolted offerings (can't get past my splash screen). But I'm very happy with Ginger9... Thanks!

While the quadrant is down a little, I can't really tell any difference in performance when using the tablet. If the battery life improves then I will stick with this one.
sorry if this has been answered before, but the undervolted
kernel still has cifs support?
(just to check, you need clockworkmod to install this, right?)

thanks soo much for this. I've been wanting to undervolt but the overclocking for me was a deal breaker. 1ghz is fast enough for any android app imo. Gonna try this soon!!!!!

Seems like your tegra can't take the underclocked settings.
Well that sucks
just curious really as my phone never gets warm or anything running at 768mhz the battery life is also pretty good.
hey,
i don´t think so, because in the worst case your phone will take damage. But this ~770 mhz are about 250 more then before. Im happy with this xDDD
that is true haha, i just dont see it doing much harm if the phone will run stable higher at the same voltage or the tiniest bit higher
No, that's the limit of the MSM7225. (Achieved by adjusting the PLL to its max, any higher will overrun the limits of the chip, and cause it to most likely fail)
i would like to know, if its very bad for the phone, if you let it permanently run with full speed. Ok, if it will get very hot.. thats clear, but is it bad if you have the 77mhz and it is for example in silent mode, or when you listen to some music. Should you ever take some possible speed away, if its not need? (thx)
The hardware life will probably be reduced. By how much, it cannot be said definitively, but, I am pretty sure that by the time the hardware fails because of overclocking, the phone will have been retired long back.
What you are requesting (Dynamically changing speed) is exactly what Speed Governors (Performance, Internative, OnDemand etc) do. If you are on CM7, use Smartass Governor, because it's the "smartest". If not, then use Interactive governor.
i use ginger yoshi... and sometimes it sais that the sd was removed. Could overclock be a reason for this?
I dont think so. I got the same issue once, and formatting the SDCard fixed it.
ok i will try it thanks

I have a sense rom on the wildfire, so I will try Interactive Governor. Do I still need SetCPU in order to use it?

To use overclocking and governers on sense roms, oc kernel and application like setcpu are must. Setcpu has governers too.

I don't know anything about overclocking on my Samsung Vibrant T959. I tried to.. I installed the Glitch Kernel HL. with CM7. Can't get to 1.2 ghz at all. I don't know what to do... Do i have to mess with the mVs at all? Please help I'd appreciate it. Anyone recommend an app to use to overclock? I'm using Voltage Control atm... Please help. Thanks.
Set cpu in my opinion is the best app to overclock.
Simply Honey 5.0 w/ 1.2 Bullet kernel. Badass Rom \m/
Agreed, setcpu would be your easiest bet.
Just install, open, slide the bar to 1200 or whatever you want.
I would recommend putting a widget on your home screen.
Makes it really easy to see what you're set on, and easy to modify.
Also, you can create profiles, like under clocking to 400 while the screen is off.
Install quadrant to get a rough idea of how the overclock is according affecting performance.

I disagree with these 2... voltage control is fine... and oc is very straifhtforward... get oc kernel, use oc app to oc... forget wut they said about the profiles, from my exp, they only make things worse. Just oc and dont touch mvs

Antutu's CPU master is another OC alternative for ya, if you are too cheap to spend money on SetCPU that is.
setcpu. best so far for me

- Agreed! that messing with voltage is more trouble than its worth.
- Disagree! that profiles make things worse. It really depends on the settings. You should never UNDERclock your "max" to anything less than 800mhz.
For example: I have 1 profile set, its a High temp profile. When the phone reaches 125F setcpu resets to 800mhz(max) - 200mhz(min). Until the phone cools to under 125F then setcpu bumps it back to 1.7Ghz(max) - 200mhz(min).
Trust me this happens often and I'm glad I have that set, haven't had any problems with it.
Setcpu seems to be easy for me!
hello xda
this is one of my first posts, and beacuse of that, i am not permitted to post in the development section af the G2/desire z forum.
i have a little problem on my desire z running virtuous unity 2.35.
i use setcpu to overclock my phone to 1.7 Ghz, but after a while it automatically underclocks to 1.2 Ghz.. does anyone know why?
Thanks in advance

set cpu only overclocks to 1.7ghz when you actually need it, like when you are running graphics heavy apps or you are multitasking alot. it underclocks to 1.2ghz at times because you dont need 1.7ghz and only need 1.2ghz, this also saves battery life. if you want it to run at 1.7ghz all the time you need to set your governer to preformance. hope this helps
You shouldn't be using SetCPU if you are on Unity. There is already an OC interface built-in to the ROM, and it works better than SetCPU.
From the Virtuous website:
Virtuous. overclocking daemon will automatically be disabled if an overclocking tools (such as SetCPU or CPU Tuner) is installed. Installing these tools is not advised, as the virtuous_oc daemon responds far more rapidly to screen state changes than any Android (Java) application.
But as evilcuber already mentioned, CPU clocking down when not needed is normal. The OC you are setting is a MAXIMUM, not a MINIMUM. You set how high it can go, but that doesn't affect how the CPU can clock up and down below that upper limit. If you want, you can set the minimum clock speed higher (or as evilcuber mentions, use a different governor), so its running at 1.7 GHz all the time . But you are just wasting battery life when its not needed. You might see some slight performance increase by running at max clock speed all the time, as it avoids any delays in CPU speed stepping. But the battery trade-off is probably not worth it.
Think of it as your car's engine revving at maximum RPM all the time, regardless of what speed you are actually moving at, or even when your car is parked. It makes more sense to just rev the engine up or down when the speed is needed. Not a perfect analogy, I know. But you see what I'm getting at?
also if u want a gui, u can download the virtuous overclock app
ohh i may not have expressed my self good enough.. i know about how the governors works (at least some of them), and the problem is that, i choose 1.7 Ghz, and quit the app, and then when i get back, the clock is adjusted back to 1.2 Ghz. maybe i should just uninstall setcpu, and let the daemon do the work?

Ah, I just upgraded to Unity 2.35 today, and noticed the OC GUI is no longer packed in. Just find the file by using the search function in the Unity thread, to install the GUI.

But which governor?
I would uninstall SetCPU. As I already said, the Virtuous team does not recommend it. It doesn't perform nearly as quickly as the built in daemon. Install the GUI app, if you want to tweak the daemon settings. If the dev of a ROM is as clear about recommended something as they are with the daemon (vs. SetCPU), its a good idea to follow their advice.
Got the same problem with setcpu.
You should try what they say above.
I run unity 2.37 : use virtuous OC gui(virtuous overclock controller) with temp+CPU widget to monitor your speed, temps, mem, etc.
With the new unity kernel you can OC up to 2.0 ghz
solid advice

You're very welcome. Be sure to click the "Thanks" button, if my post helped you!
Also, on Sept. 12, the Virtuous team recommended OC/UV Beater as a interface for overclocking the Virtuous OC Daemon. I've been using this recently, and it works great.
