[Q] clocking cpu

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.

CM7 + Kernel?

Hello everyone,
I am a newcomer to the O2X world. My previous device was an Xperia X10 and having that device for a long time it was fairly easy to follow the forums and know what route to go, which rom to get or kernel, etc.. Now being introduced to Rom Manager, and this phenomenal (to me) device its like starting all over again. I flashed to CM7.1 nightly (yesterday) and the device just only seems to get better and better, although being honest, I truly loved the Music App 2.2.2 had, as well as the camera. I tinkered around a little to get those to work without any success yet.
In any event, my real question is about the kernels... running CM7.1 nightly, what is a recommended Kernel to switch to? I am not looking to overclock the device as I feel it just isn't necessary (used to the Xperia), so Im just looking to get any fixes, tweaks, been hearing about Voodoo Sound etc to just solidify the phone.. might someone be able to point me in the right direction? I had been reading the forums for days now since I got the device but still haven't found what route to go as all the features are completely new to me.
Any help would much much be appreciated! and I must add, there are mixed reviews on the O2X but my take thus far, Im completely blown away.

vorkkernel and swiftextreme

vork is good in ironing out cm and showing off large score in tests like(quantrant etc.) while
swiftextreme is very good on batterylife
but I still prefer stock cm kernel
welcome to the o2x forums btw

hi, welcome
i stick to vorkkernel(normal version), you can get app to install in market for free.
i run it on 1,2 Ghz, with sleep profile in setcpu with 816Mhz.
gives me about 35hrs battery life and great speed in everyday use.

I am on CM7 with swiftkernel, [email protected],2GHz and I am really satisfied. I get 36-48h of normal use with 3G on and the 2x runs as hell.
Only drawback from the swiftkernel: You get a wakeup delay (1 sec.) because the kernel locks the cpu down to 256MHz when the screen is off. (Which results in a higher standbytime.

Hah, I remember my X10, used to run TripNraver MIUI on that does he even still make roms?
Anyway would stick to the stock CM7 kernel if i were you, least problems with that (no SOD, BSOD etc). On vork / swift problems keep popping up (for me at least). CM7 kernel no problems

I really dont have any knowledge about kernel!! pls help me
i am using cyanogen mod 7 and i installed swiftkernel by overclocking to 1.2 ghz wont it damage my phone??? pls do reply thank you very much in advance .....

You always take a risk when overclocking. With 1.2 it's not a big risk, but there's always one.

Thank you so much!!! can you pls tell me which kernel is good for daily use ??? i am using cyanogen mod 7 ??? when i installed swiftkernel .. i realized that it was automatically overclocked to 1015??? is this fine???

Yo...
I'm using CM Nightly's, in last week I did the install the Vork Kernel, I think so good to diary use.
Now I'm using the #201 with Vork Kernel, all ok. No BSOD and others bugs.
You can use SetCPU with personal profiles.
I'm using max 1216mhz and Profile's Screen Off: max 816 min 216. All ok in this time.
Already did one week, no problems with this.
Just had problem with #202 CM, in #197 and #201 all ok.

so bro if i am running MIUI , what do i need to do to overclock it??
sill any of these kernals be good enough or is there any specific kernal for miui??

Benchmark-Scores low

Hi there!
I'm new to the Optimus 2x rom stuff. I used a Galaxy Spica before, which I rooted and installed some nice roms on.
On my LG it seems that the custom-roms I chose so far make no difference in speed compared to the stock rom.
Quadrantscore: ~2200 with WIUI 2.5.25 Stable (GB) and ETaNa STOCK_LITE 2.6.32 which is (according to Quadrant) below the O2X.
In some rom-threads I see scores of about 4000-6000 how do I reach that? Did I do something wrong?
greetings, and thanks for your tips
reijin
//PS.: I'm aware, that those scores are not a prefect representation of how the overall experience with a Rom is, but I'd like to know. At least the new Rom feels way better then the original stock rom.

Yeah it's a bit strange. I'm using cm7 on mine, the general performance is really nice and fast no complaints from me but running quadrant benchmark I get scores of around 2200-2300. My friends o2x hits scores closer to 3000 on the same rom. Both using temasek's kernel too.
Sent from my MB860 using xda app-developers app

I only have experience with ICS ROMs and kernels, but I can testify I've consistently had quadrant scores >4000. It's a complicated mix of the hardware you have (no two o2x's are the same), whether your kernel allows overclock, how optimized the io is, etc.
Sent from my LG-SU660 using xda premium

try to use antutu benchmark and see your score. and you're using stock lite which is 1.0ghz the clock. if you want to get higher score try HOC lite, and use OC/UV programs to control your clock cpu. i use pimp my cpu profile i set:
- daily freq: 216-1015MHZ.
- bench freq (like antutu,quardrant, necore, vellamo, and so on): 216-1418MHZ.
- and so on, what ever profile you want

You used spica and you don't know this basics?
Spica's angry anboys can tell you.
I can say that high quadrant scores can be resulted when IO rate is very high. You can cheat quadrant at it will think IO rate is high but it won't make phone a formula 1.
Use app2ad or something that uses ext partition and then run quadrant.
I am afraid y used spica and didn't know it.

[Q] Best Galaxy Ace Overclock Frequancy... And something else thanks

Hey guys
I know their probably another thread out there with this in it but... Yeah. But go ahead troll me lol, im still a bit of a noob.:silly:
Anyways, i have a Galaxy Ace s5830. I have Beats with smooth sense ROM. I had it upto 883MHz Yesterday but after i turned it off then back on ROM Toolbox reverted it to 806MHZ. 883MHz seemed a lot faster even though some people get theirs close to 1GHZ
My phone afterwards rebooting had issues such as the phone becoming un-responsive when i was even doing nothing (maybe the overclock to 883MHz had some short term effect?) But the phone seemed fine after safely turning it off then back on several times. Still works perfectly i got scared when it started to become un-responsive. But it works well now i have also used pimp my ROM, and the scripts work like a charm. Especially the call quality one (it uses bravia engine or something?). But with pimp my ROM wi-fi and network tweaks it completely broke wi-fi saying wi-fi connecting... Then saying under the network name 'Error'. Dam it took so long to get the IP address then said error like i said lol
At the frequency 883MHZ the phone seemed stable and faster than ever before, i did change it in small increments
So just wondering, what is the safe and most reliable frequencies to set it at? I currently use 225Min and 806 Max. With the userspace governer.
I know the terms of ' Safe ' and overclock don't mix (sorta like water and my dads S2 :crying: ).
Im also considering buying a 2450MAH battery from ebay for about 5.99 AUD. Any suggestions on should it be okay and better? But i mainly would like to knwo about the overclcoking lol.
So yeah, basically what is a good frequency to set it at? Is 883MHZ okay? Am i going to fry it out or completely brick or damage the phone or cpu if i set it at 883MHZ? Would love to buy a new phone but i need to save im only 14
So yeah please help me and you could help others too. Please be welcomed to troll me
I plan on having this phone another 3-4 Months before i consider buying the S2 or Galaxy note when their cheap (like really cheap)...
Like i said please help, and feel welcomed to troll me when you do help :highfive:
Man i feel like a Rebel when i overclock

That battery is a fake and has been confirmed as such. If you want a higher cap. battery get a 1500mAh or 1600mAh. I don't like messing with the clocking, good luck to you.

Thanks

Thank you for informing me that the battery is a fake ... But the seller has like 96%/100% seller rate or something?
Thanks for all your help, i hited like
Sorry for my 'Noobiness'.
What battery do you reccomend? or should i consider getting a AA battery to USB power charger?

i'm pretty comfortable with 825 or 844 mhz

It's pretty good with 614 MHz lol

Running smooth even on 614 Mhz.

Right now I am just using the stock one. I personally wouldn't change my battery to anything other than stock, but people have reported that 1500mAh or 1600mAh work well. I wouldn't use anything that has a higher capacity than that though. Also, if it's very inexpensive it's probably not real.

Clocking actually goes on the rom. I've seen people having OC over 1gHz & still stable with the mad kernel but I gave up clocking as I didn't see much of a difference & also underclocking started giving me FCs on some heavy apps while it was all fair in the unclocked state. And again, there's no such thing as a best frequency. You find your own values. What works well for him might mess up your phone rebooting all by itself. Stock batteries are always fine & they also keep you under warranty. Anyone ever wondered why the phone manufacturers didn't implement clocking as a part of it ? Stability is the word. I've seen here, I've seen there. East or west, stock is the best ! Try keeping as close to stock as possible, just to have that extra touch of safety & stability

Hello all.
I was reading this thread and became interested in overclocking. In my case my device is:
Samsung Galaxy Ace GT-S5830L (labeled as GT-S5830 by CyanogenMod)
CyanogenMod-7.2.0-cooper stable (Android version 2.3.7)
Kernel 2.6.35.7-perf-CL882825 ([email protected] #21)
I was checking in CM settings -> Performance -> CPU settings that I could adjust min and max clockspeed, but in max frequency the maximum one is the same processor's speed, 800 MHz. So my kernel doesn't support overclocking.
After a search in the forums I found there are plenty of custom kernels for this legacy device. But I'm relatively new to the kernel world, so I wanted to ask you for advise. What custom kernel could I try for my device for overclocking? Or King Android, what custom kernel are you using?
It'd the first time I do the overclocking stuff, I'd like to try it to see if some higher quality mp4 videos (which are run by MX Player only in software acceleration) can run better, as well as some games and emulators.
I'm also kind of a noob as you can see. If you want to troll/scold me...
Thank you all.

Hi you can try FireKernel or BlackHawk kernel. Use the search function to find them easily. Both supports Overclocking and are made for CM7. [MAKE SURE THEY SUPPORT YOUR S5830L]
At the moment I'm with Democracy ROM which is based on unofficial CM7 and I don't really feel the need of overclocking. It is all smooth with firekernel at
Min 245
Max 806
Governor smartassv2
Sent from my... oh wait, who cares?

I did my search.
Maybe I forgot to mention I haven't installed a custom kernel before... Does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I already mentioned what CM7 I have installed. It's the "official" stable one.
Would OCing help to improve videos and games performance? i.e, faster, no lag...

You can set it to whatever your phone can handle. Mine can't go past 844Mhz otherwise apps start force closing and such. If your phone is completely stable at 883Mhz then you're good.
As for the battery, no. It's a fake. Buy a 1500mAh like I did. Works like a charm and it brought 3. Lasts a little longer and it's really amazing. Had it for a while now. Still have one in the pack, only been using 2 when I don't get to charge my phone. Really handy.

OCing helps the phone over all. But remember, without much free ram, OC won't really change much. You need a balance of ram and CPU. Like me, I use swap and OC to 844Mhz. Even if it's a low OC, it's still better than nothing.

1. @SuperAce609: I have 104 Mb free RAM out of 278 Mb total RAM. Mine is Galaxy Ace S5830L with CM 7.2. Would OC work for me? Up to what frequency?
And how can you have 600 Mb of RAM? Is your device really an Ace?
2. There's still a doubt I haven't been able to find out myself: does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I was suggested FireKernel or BlackHawk ones...

Any help?

1.- Every Ace is diferent..some Ace's can go up to 960 Mhz while other just 844 Mhz, the thing is: try it yourself overclocking in small jumps. Swap is a small amount of memory of your SD card, that Android use it like if where RAM, but decreases SD card life...
2.- Some Kernel came Built in on Some particullary ROM's but generally cames on a CWM Flashable zip; FireKernel & BlackHawk are specially for CM7; In my opinion FireKernel is the best... And there are others like Battery Extender Kernel or NimsKernel but these Kernel are only for Stock ROM's...
I hope you find useful my info...

Thank you, Blake2893.
Then there's just 2 doubts left, if you don't mind.
There's a fair number of custom CM7.2 roms with FireKernel in the developer forum. Is there one you or someone else could say is the best in terms of stability and least number of bugs? Or is that something I should test myself in the S5830L?
The Ace S5830/S5830L has 278 Mb total RAM by default. If I understand well, you're implying I could modify SWAP partition in order to increase RAM and, probably if lucky, with this make OC work better. How can I do that? Do I also need a custom kernel/rom for that?

The best stable Roms so far are the stock GingerBread based ones... but if you aks me about CM7 there a few like Apocalypse rom(ICS styled ROM) with the FireKernel that suports swap I think...
and for Swap you only need a Kernel with Swap enabled and a SWAP Partition on your Sd card...

lets see im fine and stable with 979 mhz without reboot for 9 hours
overclock is depend on your hardware

best over clock freq.

Best Kernel for RR ROM

Hello.
I'll be unlocking my bootloader soon, at first I wanted to install the Xiaomi EU rom but then I found out about all these beautiful ROMs and I couldn't decide.
I don't like the Pixel Experience ROM because I don't have that freedom of editing/customize the theme etc.
The Resurrection Remix ROM seems the best in that case, and I've heard it's also great performance wise.
What Kernel should I use with it? Does it drain much battery? More than standard MIIUI?
Thank you in advance

Generally, the kernel included with the ROM will be most stable, I use RR Oreo + Gabriel back then, it was almost compareable battery life (or drain a lot more) but heats more than what Xiaomi.eu + Gabriel for me and that might just be what makes RR drain more.
You can try Clarity and maybe it performs better, but generally I like Gabriel better because of how much you can tweak the kernel

Clarity sounds cool, which version should I download?
There's one with the CPU overclocked and one without the overclock

Obviously without overclock is best with your battery, if you want a balance I would set the BIG cores at stock frequency, and overclock the LITTLE cores for whatever, which I am not sure if Clarity can do, but I heard 2.9 has been good, though you will miss out on lots of updatea up to 3.7

Clarity works very good no issues latest version is 3.8
