hello all i have a nookcolor running cm7, i didnt really want to ask this question cause i no it has been asked alot, i searched and didnt really find a clear answers, so ill ask this one time and save this link from here on out so here it goes... what is a safe cpu speed when you oc the nook? how do you figure out what is a safe speed? the max,min and the goveners to choose? thank you all!
Hi! I thought that this would be a great place for my first post. I've been running CM7 for 8 or so months from an 8gb uSD card. I had my settings on 300mhz min and 1.1ghz max. I've heard of people running at 1.2ghz with no problems and others who had to clock down to 1.1 for stability.
I've since switched to CM9 and I love it so far! I have been trying 1.2 for a while and have had no issues. ymmv
As far as the gov, I use "conservative" for the battery life. "Performance" would be better for speed, "on demand" is a compromise between the two, I think. "Interactive" I have no idea about!
EDIT: There is a good explanation here in the first post: http://forum.xda-developers.com/showthread.php?t=843406

Hey all, I bought a Wildfire for my girlfriend this morning, I should be receiving it in the next couple of days. I had dropped a post in the WildPuzzleROM thread as I am liking the look of it, however I got no reply. So it seems I'll have to clutter the place up with another thread. Here is my original post:
Kalavere said:
Hey folks, I am considering getting a Wildfire for the girlfriend, she's sick of her pathetic Samsung something or other. This ROM is just what I am looking for, close to stock Sense with a decent kernel. However I was a little concerned about the CPU and it's lack of power, so with that in mind I have a couple of questions regarding it.
Is the CPU underclocked when used with the stock kernel, and how does it fair with the 768mhz overclock? How does it affect batterylife as well? I get a good day out of my OC'd Desire, I don't want to leave her short of juice.
I really like the look of the phone, I'm sure she'd love it, but I don't want her with an underpowered device (Not that she'd care, but it's just another device for me to tinker with. ) so I figured I'd as you fine lot first and see if it was a little firecracker when rooted with Froyo.

So as you can see I am curious about the battery life when using a 50% overclock, and wether or not the CPU is underclocked by default with the stock kernel. I don't want to burn out the her CPU just so she can get a few more smooth frame rates.
Any light you guys can shed on my questions would be greatly appreciated.
The overclock is on demand , i get about 12 - 18 hours with it set at 254 mhz - 768 mhz
Hope this helps

The CPU on the stock rom is ok. If u want something faster, look at the htc legend (wildfire has no gpu either)
I have moved from CM7 to Hombase 5.4, and found that setcpu no longer seems to do anything. on CM7 it worked as i had hoped, underclocking the phone when i was doing low intensity stuff like texting, and pushing it up to full power for videos etc. now it does nothing but tell me core temps, which are always high as its always running at 1Ghz.
Can anyone explain how to get it back to underclocking?
Many Thanks
Try a different kernel.

This is a known issue with the OC faux kernel. I was running into the same problem with his enhanced stock kernel after using webtop. After reflashing the enhanced stock 0.2.0 it would still get stuck at max 1Ghz after using webtop, but a reboot would get the underclocking working again.
I only tried the webtop hack to see if I could get it working. I haven't gone back into it at all so I don't know if this is something that will reoccur. Although I will say that with my day to day use I have not run into any clocking issues since.
Thanks, is there a page somewhere which details which kernels do what and which would work with my rom?

This is the page for faux's kernels. As far as details, start reading and searching through that thread as well as the threads for any ROMS you are using. 99% of the time people will either have the same problem (and possible fix), the other 1% of the time they will identify a bug (i.e. maxed out CPU).
Keep in mind faux does have different kernels for Froyo, GB, and CM7.
For some reason even if I move the slider from 1300my to 1000, when I touch the screen with at least 3 fingers for a few seconds it pegs out at 1300. I read our cpu's are daisy chained so to speak
so the 2nd core kicks in when needed. I tried cpu tuner and it gives the option to powersave and only use one core or if you choose performance it will allow Both cores. Just might be setcpu isn't designed fully for our dual core setup.
thanks for the link to kernels, but i cant find one for HomBase, or a Kernel only download on the homebase thread. i have the Version2, which has some blur, but only the 1.0Ghz clock kernel. where could i get the 1.3GHz download by itself, to see if that might help, as its the one CM7 had iirc
Thanks

Get the 1.3 from the faux thread that I linked to. They're in the very first post...
CM7 is the only ROM that has its own custom faux kernel. For all other ROMS just match the kernel to the build the ROM is based off of (Froyo or GB). If you're using V.2 of Homebase then use the GB one.
Update: Also, there are other kernels out there. I was only using faux's as an example since you were using CM7 and Homebase.
thanks, ive now got the 1.3Ghz kernel installed successfuly, but it still seems like setcpu will not underclock. i dont know if its normal, but the "Scaling" option is greyed out, and i cant get access to the Advanced tab. is there something im doing wrong in setcpu itself?
thanks again

Lack of underclocking is a known issue with the latest OC kernel. I'm unclear whether it's actually a bug with the kernel or with setCPU not supporting dual core devices. But yeah, there's a problem with it right now. I'm on the stock enhanced, and other than the webtop issue I mentioned above, it works fine.
Scaling/advanced are not available, this is something that is determined by the kernel you are using not the app.
ok so if i understand you right i would be best off using the stock enhanced kernel (for now), as it will underclock fine?

It's working perfectly for me, except after webtop use (which I don't normally use).
I'm still having the same issues regardless of weather I choose power save or performance it will not underclock, and those are the only governors I get the option of :s

Lagfree, on Marc's Kernel. Awesome, but not in your poll.....
I think this should be moved to q&a.
My favorite: smartassv2
Why? It includes a stanby management, is stable and fast.

You shoulda posted in Q&A
But i use smartassv2 with my OWN custom settings and i use it because it gets great performance with amazing battery life
I am still working between different settings on TBD. Lagfree with Marc's kernel is good but I am now working with smartassv2 with custom settings. So far so good
Lagfree 128 - 1190
btw, this should be in the Q&A
It sucks that majority of governors have no description, so only way to decide between them is through trial and error (which is very tedious given the number of governors and differences may only be placebo) or by reading other's recommendations.
I was using convervative with a heavily customized settings, then smartass/V2/smoothass (switching between them, AFAIK they are very similar anyway), but now I'm testing Hyper as it's default on new DORIMANX.
moved to Q&A
Not sure if this is a thread to post this sort of problems...
Anyway, at the moment I got a HD2 running flawlessly HyperDroid-CM7-v5.9.0 with smartassV2 governor and I'm very happy with it.
The problem is that as soon as I switch to for example interactiveX governor I start getting freezes where the phone is left screen on and nothing else working.
I've been previously dual booting wp7 and android sd. Back then I had same sorts of freezes on android but would just tweak my auto memory killer to less aggressive settings to not get freezes. I'm a bit confused on this but after all quite sure that this is about something else than memory related problem.
Any ideas?
I have also tried few of these governors, but I think that there is no big difference between the better ones like hyper, ondemand etc. just a placebo when somebody release "new" governor
I recently flashed the newest Trinity Kernel on my Nexus 7. I still have the stock ROM. I tried to tweak the CPU settings with ROM Toolbox and the most I can overclock is 1400mhz. Why can't I overclock to 1600? Is it because of the stock ROM? I'm looking into Glazed Jelly Bean as a custom ROM but I'm not sure I want or need to use a custom ROM at this point.
Any suggestions?
Because he dropped the Max. You probably flashed A111 correct? That's a TSVZ meaning it is slightly over clocked and undervolted kernel meant for battery not for performance.

Mildly on topic question ... do you notice any imporvments with overclocking? My first experience with overclocking as on my Hero, and then Galaxy S1, but this N7 just feels so fast i cant see overclocking making it any smoother? lol
thanks

Nice, ill have to look into rooting sometime soon.
Ok, I got the a96 and I've flashed it...
Is there a detailed changelog for each version? The a111 said it was a 1600mhz kernel so I don't understand why it was dropped down to 1400. That's where my confusion was.
I did notice some increase in speed at 1400. I was having some stuttering issues with Dead Trigger and Minecraft PE, and they were less with the 1400. I've got it running at 1600 now but I don't know what it will do to the battery or how well it will perform. I'll find out later. I've run through the battery pretty quickly today, but I was tinkering with it A LOT so it's not accurate.
What kind of tweaks could I do using Rom Toolbox that would help me maximize my battery while overclocking to 1.6?
Dont over clock.. i dont even see a need to. I use the ondemand gov which stutters a little but using interactive clears that up. Also using the CFQ IO as it is the stock IO used. Its stock so its gotta be good . Also you should turn F-Sync off that helps quite a bit. Also you could toggle auto hotplug and make it only run two cores while gaming and then turn it back on when finished so that way it will hotplug cores as it sees necessary. You could also up the voltages a little bit, some CPU's dont like the lower voltage and that will cause stuttering and glitching just up them by 25mV and see if it clears if not try another 25mV.
I will try those things, but I really want to play with overclocking and learn what happens. This is my first Android device so I'm experimenting and playing around.
But I have one more question...I've overclocked to 1.5...I found 1.6 to be the same as 1.5. But it seems that after an hour or so, it resets to 1.3. in ROMToolbox. Why is this?
Don't use rom toolbox. Use the Trinity app. It sticks just fine for me. Besides you support the dev to make better kernels.

youre not the first
Overclocking past 1.4 Ghz doesn't result in any major usability improvements. I've gone up to 1.7 Ghz and the only thing it does is make my tablet really warm and unstable. All you really need for improving system performance is I/O tweaks to speed up app and page loading, and a little bit of GPU overclocking to help with the transitional effects.
and, to be honest, depending which trinity kernel im using, im using either 1100 or 1150mhz mostly. on a111 im using 1100mhz and on a96 i used 1150mhz. with those speeds everything is still fast but a bit better on battery
Overclocking
If you want a little more information about the the overclocking if you havent already you might want to check out http://forum.xda-developers.com/showthread.php?t=1788759 its the official thread of the trinity kernel for grouper.
Hey everyone, I have been on the hunt for the last few days for the best Kernel for my N7, in regards to performance. Earlier today someone turned me onto M-Kernel. I must say, it is very impressive. It has a built in 1.9 GHz overclock, that I was able to set via no-frills. I am running Clean ROM.
This is a multi-purpose post. First off, I wanted to let everyone know about my experience because I had a little trouble figuring out the best combo. The second reason is I would like to know if anyone knows of any other ROM/Kernel combos to get the highest quadrant score possible.
I have a co-worker who has a Galaxy SIII, and we have a friendly rivalry. I would really like to blow his phone away with my Nexus.
Thanks!
Check the link in my sig for my guide to the 'best' kernels. I don't think there is a lot of difference between roms in terms of benchmarks results.
