Feedback:-

kernel with 1.3ghz:-

After flashing kernel first time device didn't boot. I have to remove battery. Then in second attempt device successfully boot. But as soon as u set 1.3ghz frequency screen gets distorted & device gets completely hang. We have to restart the device. Tried 4 times but same result :( So overall 1.3 ghz is very unstable.

kernel with 1.2 ghz:-

Like always works perfectly. Not a single issue. :)

kernel with 1.25 ghz:-

I will post result later.

3009: very unstable

2009: is more unstable than 3009

1009: No issues
[Samsung Galaxy SL i9003] !n0x:
Tested. Will test others as soon as I can download them.

Setup: XXKPQ + Deodex + GPU Render + Touchscreen Improvement Mod

1009: Stable as always. No issues or anything.

Setup: min: 1200 max: 1200 smartass v2 (setCPU)

- for some reason, the min value always resets to 300 even after I hot booted it.

- responsive

2009: Quite ok.

Setup: min: 1250 max: 1250 smartass v2

- no issues found yet.

3009: Surprisingly, it's stable for me O_o and fast too. No FCs, no distortions or any abnormalities yet.

Setup: min: 1300 max: 1300 smartass v2 (setCPU)

- Gallery has been very smooth! And all the information loads quickly :)

- Opened a lot of apps at the same, no lag in between

- All in all, phone has been responsive as ever

- IDK yet about battery drain. I'll have to test it out some other time

i found wifi error on 3009..anyone had same problem?
[Samsung Galaxy SL i9003] DooMLoRD:
No overclock is battery friendly... It's for those who want more performance and are ready to sacrifice a bit of battery life...

1.20/1.25 GHz - 1400mV

1.30 GHz - 1450mV

I have tested WiFi to work fine on all the test kernels before uploading them.. check screenshots...

I HIGHLY RECOMMEND that u DO NOT SET MIN/MAX CPU FREQ TO HIGHEST POSSIBLE

atleast keep the minimum 300/600/800 MHz

kindly explain in details as to why it was "unstable"

its very much expected that 3009 will be unstable while 1009 will be stable...

whenever anyone is posting such info always provide as many details regarding ur test setup as u can (firmware/ROM, baseband/radio, cpu min/max, cpu governor used, i/o scheduler used, etc)... it will help us understand the testing conditions a little better and might help pinpoint the issue...

@ALL

Every device is different... Not all devices can handle low/high freq/voltage...

That is why multiple test kernels are provided so that u can test all for stability....

as an example take the case of the previous kernel... not all devices could handle 200MHz underclock... on Xperia X10, some devices couldnt even handle 10% overclock / 25mV undervolt...
[Samsung Galaxy SL i9003] skchattha:
Tested #3009

very stable; wifi working, Bluetooth working; data connection working; no FC, no lag; no hangup, no reboot, no SOD etc etc. in fact i never got any issue on any of DooMLoRD kernels be its matter of working on 200 MHz min or 1300 MHz max. :D

I did not test 1009 and 2009 as i know that will work obviously:D

and yes, i always use scheduler IO - vr; governor - Leonheart in both setCPU and no-frills.

#3009- stock kpq with framework customization no issues at all ! played brothers in arms for 15 minutes and no problems no freezes no hangs no lags :D all the cpu states work fine :) battery drain while normal usage is 1% for 4 minutes :) thats gud battery at such high clock :) + the device didnt even heat up much while gaming reached only 45*c (room temperature 29*c) so its al gud :)

Edit-tried wifi and its not working ! very strange ! its connecting but cant load pages or download ! it even gave me an "error" in the wifi settings and had to reboot the device and its fully functional on the 1009 version 1.2ghz one

I have ddkp2 i was with BAM v8 kernel till last 3hrs, whcih was super fast with good GPS and no lags, But i always prefered UC7 whcih was good in all respect but Lag was there, v9 is superfast as it is in BAM v8 no lags, and Quaterent Scre is 3192. i am using noCPUfrills to set these kernel settings, 1.3gz Smartassv2 and io as cfq. all is well till now, lets see for batter usage. wifi no issue, Bluetooth no issue, GPS in building having littel issue. where as BAMv8 kernel was fine in building. so look at it rest it is roocking. but in last 3hrs my device did not go in deep sleep mode even i set in nofrills tool. is that a bug or deep sleep is not implemented. you guys are roocking just 100mz to reach galaxy note.

---------- Post added at 11:20 AM ---------- Previous post was at 11:13 AM ----------

Sorry guys Deep sleep also works after usb cable was removed from mobile, is it recommended to set in Nofrillscpu to have deep sleep tick or does kernel do on its own.
[Samsung Galaxy SL i9003] DooMLoRD:
device will never enter deep sleep when connected via USB cable...

deep sleeps gets controlled by kernel and by the wakelocks of apps... ideally device should be in deepsleep for 90%+ of the time, depending on usage... if device isnt entering deepsleep then u need to investigate which apps are waking up the kernel often...

[Samsung Galaxy SL i9003] skchattha:
1.3 GHz speed is wonderful but stability has concerns; had to go back to 1.2 Ghz due to:

battery consumption is high

few games like riptide gp, angry birds, chess racer etc. not working

Also few minor issues with camera

1.2Ghz is the best overall.

Edit: Keeping on 1.3Ghz, found a way. whenever needed reduce the frequency to 1Ghz for such games and apps.

[Samsung Galaxy SL i9003] alex88510:
So, today I test v09 #1009 and #3009 kernel.

first I flashed the v09 #3009 kernel, flashed from v07 OC kernel.

Everything looks great, boot with no issue, speed is great.

ran antutu benchmark and get 3148 score. before this is around 2900+-

min:300mhz max:1300mhz Gov:smartassV2 IO:deadline

then I boot into recovery.

wipe cache = OK

wipe dalvic cache(not sure the spelling) = show error E: path XXX (sd-ext) not remember the whole phrase.

wipe battery status = OK

reboot, then I go and play angry birds. No issue at all.

Capture some pic using camera, not problem.

Then I think of someone report said that the wifi issue.

So I go and test it, and problem came out.

The wifi is stuck there, can't connect nor disable it.

Here is the screenshot.

Then I tried to connect the phone to computer using cable(USB mode)

The computer seems cannot connect well, it saw the device but I can't browse any file neither from internal SD or external SD.

And then the phone turn off the screen (screen timeout) but I'm not able to wake the phone. Have to force reboot the phone.

After force reboot, wifi issue same, and then during tried to connect to computer, it stuck again.

Here is some profile I used in SetCPU.

Flashed to v09 #1009 kernel, wifi no problem, USB mode no problem.

Still testing it:p

[Samsung Galaxy SL i9003] supergaijin:
I've encountered this issue a few times when flashing, especially the combinations of cfroot universal (the version with EXTRA for changing boot logo) and uc kernel, both on uc5t6 and uc2009 test. the kernel would be reported as "unknown". flashing again as necessary makes it work without issues.

I did pit, kpe, kph, kpq (as usual when flashing stock, never any problems by itself), but then, the first couple times I flashed cfroot universal and test 2009, I had a few random restarts, and the first time was actually scary for a minute 'cause my "back" and "home" buttons stopped working, and my lockscreen wouldn't activate when I tried. flashing yet again for a third time seemed to solve the issue, but only after one more random reboot.

* and yes, I did wipe all caches and factory reset as needed. everything is playing together nice for now, with smartassv2 and vr.
[Samsung Galaxy SL i9003] longfeng:
Flashing KPH is a mistake cos you upgrade KPQ from KPH instead of KPE.

Me report:

Flashed 3009 - no problem, but experienced hot reboots.

Was investigating, arrived at conclusion hot reboots happened when CPU is at 1.3Ghz for a definite time.

Played Angry Birds, browse through the net using stock app browser... no problem. But when playing Gameloft, playing high resolution movies, at a certain time the phone freezes from 1-5 seconds then hot reboots, meaning to say phone rebooted immediately that you can no longer see the Samsung logo and that it will instantly show you the boot animation signifying phone rebooted - but a hot reboot.

So, flashed 1009 instead. Played Gameloft, played high resolution movies, no reboot - stable.

Not to mention, 3009 got no problem for me about GPS, Wifi, Camera, Messaging, Benchmarking, etc.

[Samsung Galaxy SL i9003] arindammanidas:
As Doomlord said, there will only be one version from now on. It is better that way. If you don't want overclock then select 1000 Mhz as maximum frequency in No Frills CPU Control or Set CPU.

I personally Use SETCPU app.

Gov:SmartAssv2 & Default Scheduler(Since Setcpu has no option for that)

Just perform the Following Steps in ur Device:

-> Install Fresh Stock ROM ( Try DDKP2 )

-> Install UC Kernel V8 OC.

-> Enter CWM( Recovery Mode)

-> then Wipe Data, then Wipe Cache, then Wipe Dalvik Cache.

-> Download Seperate Ex4 Addon Apk From AMit`s CWM Post http://xdaforums.com/attachment.php?attachmentid=819056&d=1324066597

-> Convert Your System to EXT4 System by Using Ext4 Addon Apk By Amit.bagaria

-> Then Install UC Kernel V9 3009 and Set Freq to 1.3GHZ and Test.

These Are the Steps I Followed In my Device , I hope it Works For others Too...:cool:

I'm still using 2009 with no distortion or reboot issues even after doing kpe->kph->kpq as always (yeah, I'm taking a shot at you, longfeng, for saying I'm wrong when I never have any issues after successfully installing it :p)

since a few others had said 3009 was causing problems I didn't even try it. what did you do when installing 2009? any wiping or anything else? what are your settings?

yups we have been trying the same... but currently we both are really busy with some work so we will continue work in a few days...
[Samsung Galaxy SL i9003] inciongd:
Some quick facts for those new to overclocking in general:

Just a few things I like to mention which I think would be useful once we get past 1.3 GHz. This is for new guys to overclocking --electronics engineers and experienced overclockers can ignore this :P

Imagine chip production as baking a pizza in the oven. Our chips were once part of one large round pie or "wafer", which has been sliced to little pieces or "chips" and then packaged and put into our phones. As with a pizza pie, each "slice" of a semiconductor chip is different. Some will have more pepperoni, others would have more onions, others would have more cheese -OR- some chips would have more more leakage resistance, thinner or wider electrical pathways or more or less heat resistance etc.

This is why not all chips will be able to overclock the same level.

Now as DoomLord has informed us, UC v09 has the following specs:

1.20/1.25 GHz - 1400mV

1.30 GHz - 1450mV

Notice that there are 2 values. Frequency and Voltage.

See, a chip needs a certain voltage to work properly in on a certain frequency. Lets just say that the higher the frequency the higher the voltage needed to run the chip.

So, for those that are unable to run 3009 or 2009, this means that your chip or "your slice of the pie" probably has less cheese in it than others. For your chips to overclock properly, you may need a bump in voltage to to boot at 1.25 or 1.3 GHz.

Maybe if your phone does not work for 3009 and 2009 values, it would work with these values:

1.20/1.25 GHz - 1500mV

1.30 GHz - 1550mV

But, since the voltages are higher, there is more risk of frying your chip. Making it put out more errors or making it stop functioning altogether. And, like every pizza slice is different, every chip has a different breaking point.

Some chips will break at 1.1 GHz and a small voltage bump, others will not break even if you push it to 1.4 GHz and a higher voltage bump.

I would just like to highlight the risks for everybody since probably in the future we will be going to even higher frequencies.

Test your phone incrementally, don't flash the highest clocked kernel immediately.

Start with the lowest first, test for stability then move on to the next higher clock. Once you get some instability, you are near the limit or your chip, just stop, and maybe flash the next lower clock.

Unless of course you are really ballsy and it does not matter if you break your phone! :D
