Overclock Kernel Question

So I found a kernel on the Fascinate forums that was built off of our EC10 froyo source that was from nemesis2all and I saw that he had added the ability to overclock and undervolt from within the ROM so I installed it just trying (backed up of course) and found that it does indeed work.
I then got the Voltage control app from the market and started playing around doing Quadrant scores throughout after each change. I found that at 1200 mhz I was getting 1600s instead of 1400s and the phone ran great. But when I tried 1400 mhz the phone froze up and restarted while doing the CPU section of the Quadrant test so I reverted back.
My question is, what would be safe to stay at for general use?
Second question, how do you use the voltage app to undervolt I see the settings but I don't know what to set them too.
Here is the link to the kernel

1200 has proven to be the most stable overclock, any higher and it will freeze up eventually.
With voltage control, the way it works is that you set the max clock and then it will give you increments that the phone will automatically clock to within the guidelines you give it. Then for each increment you can set the voltage it will use. Just look around and experiment with voltages, see how low you can go without having issues and never set it to apply at boot unless you know that's what you want, other than that go crazy and a reboot will fix it if you have a problem.
I recommend keeping setCPU installed along with it, that way you can still force it to underclock or overclock or whatever. It all depends on how much you use the phone and what for.

Thanks sage I'm glad someone who knows what their talking about replied lol.

I've been running overclocked at 1.3 and undervolted at least 50 for a couple days now. Only one issue and I'm not even sure it was related as it janet happened again. I posted my settings in the otb thread if you're curious.

H'm, I tried going up to 1.3 and it would freeze up after 5 or 10 minutes every time.
Like I said, 1.2 is the only one that has proven to be safe for everybody... not each phone is exactly the same and if akellars CPU has a soldering that is done a little bit different than mine, it might allow him to clock a little higher. who knows
Sent from my MIUI SCH-i500

I've been running it for a week @ 1400 -25 undervolted and haven't had any issues. The new 1.6 gives me trouble. I don't think there's enough overvolting in that one to make it stable for pretty much anyone. I use the 1400, 800, 400, 200 steps all undervolted @50 except 1400 which as mentioned is -25. Battery life is good because during sleep it doesnt really hit the high end and by not having the other steps its snappy when in use. Fastest this phone has been by far. I don't use setcpu because I think it and the voltage app conflict. That was nemisis's instruction to install it.

Yup I'm just lucky 1.4 worked for me too but I didn't see much of a performance difference so I didn't see the need to stress the cpu out anymore than I already was. battery life had been awesome for me with my setup as well.

[DISCUSSION] PB&J Frequency/Voltage

I just wanted to start a post so everyone can share which setting are working for them insted of digging through the PB&J OP.. Im running at 1400 mhz.. I havent started tinkerimg with the voltages yet.. Also if there is any info anyone thinks people should know about let me know and ill added it in

900 right now with the voodoo fix. Seems snappy enough for me.

please someone post on this because my phone crashed so much I had to do a full Odin an wipe. Used many kernals...but this ones kill in me. Any post of how to set up pb&j would be much appriciated.

I messed with my settings.. I have 1400-1100mhz knocked down 75mv and everything 1000mhz and under I knocked down 100mv... Its working fine for me

I don't understand what problem you are having? Did you have PB & J installed and started overclocking and the phone crashed? If you were using the Voltage Control app then it should have just rebooted and reset the clock speeds.

I'm impressed you got 1.4GHz stable at -75mV. Can it run stability test for 30 minutes without crashing?

Lol I dont know what stability test is but ive had this setup for over a day and no reboots or anything.. When I say -75mv I mean 75mv under what default is... At 1.4ghz default voltage is 1375mv and I have mine set at 1300mv.. Idk if thats what you were saying by -75mv

Over 1.2GHz = Lock

Hello everyone. I have had my Nexus S 4G for about 2 weeks now, and I have tried everything I can think of. However, I cannot overclock my phone higher than 1.2GHz. If I set it to 1.44GHz (or even 1.3GHz in most kernels), within the first five minutes, it locks up, requiring a battery pull. I have tried just about every kernel. Trinity, Netarchy, Matr1x, everything. However, I get the same result. I am assuming that it is just my phone. I know that when I had my Evo, it didn't want to OC past 1.1 GHz stably, but the refurb I got from Sprint ran at 1.21 GHz like a champ. I was just wondering if anyone had the same issue, and if so, if it was possible to alleviate this problem. I would love to run my Nexus at 1.44 GHz, because some of the Quadrant scores look amazing.
Thanks again for reading,
StompySan

After running Quadrant twice with it set at 1.3, I got a lockup. 100% not responsive. Had to pull battery.
EDIT: I tried benchmarking my phone with CF-Bench, thinking maybe it could have been a fluke with Quadrant, and had the exact same results. At 1.3 and 1.46GHz.

1.2??

Ok if neither of those work I need you to do 2 things.
1. Raise all voltages by 30
2. Set it to 1.2 ghz
Sent from my Nexus S using XDA App

I can overclock without reboots to 1.2. Any higher than that is when the problem arises.

Ok now once you flash v9.0, go into setcpu and raise all voltages by 30
Now try 1.3

When you say all voltages, you mean even the ones that it already runs stably on?

No no, just the unstable ones
Sent from my Nexus S using XDA App

OK, so Quadrant ran fine for 5 tests, and CF-Bench ran OK as well. Should I push it up to 1.46 now?

Try it, and if you get a reboot, raise voltage for 1.46 by 10.
Sent from my Nexus S using XDA App

No lockups yet! I have ran Quadrant 5 times, CF-Bench 2 times, and Linpack a couple times. Seems to be doing great! I am going to test it more thoroughly tomorrow (it's almost 1AM where I live, lol), but it seems great right now!
I have never increased the voltages on a phone CPU before. I have done it on my brother's computer when I overclocked his processor, but I generally try to avoid it. I am just really paranoid to mess with the amount of power going through the processor. That's why I turned to the professionals in this case. Thanks again for your extremely quick reply.

Cool! you just needed a bit of a voltage push, that's all
let's hope 1.46 ghz runs well

Mathkid Ive never been stable past 1.3 so I followed what you told him to do and what do you know! Perfectly stable so far at 1.44 on apocalypse kernel!! Might have to try your 9.0 at 1.46 soon!
Sent from my Nexus S 4G using XDA App

So is there a limit to how far one should overvolt? I upped the voltage at 1440 mhz to 1550 mV. Did run rather stable except for "Lets golf HD!" which froze. I would really like to be able to run at 1440, but not sure what to do. Im using Apocalypse Talon 3.2.1.
Do you think your kernel would handle OCing better, mathkid?

Yeah you can try it out and if you need to raise voltages go ahead

FauxClock 0.8

Just wondering how folks are finding FauxClock 0.8.
I managed to find it and am trying it as I was on 0.72 and 0.75 didn't work well for me.
Any views ?

0.8 FC every time I start it, so I roll back.

Thanks, but now it keeps saying CPU1 is offline?

Keeps force closing, how do I fix it?
Sent from my HTC Sensation Z710e using XDA Premium App

Make sure you un-install old version first or wipe data if coming from an ealier version.
If it says CPU1 offline then it means that it's not needed and has shut down. I have opened it a couple of times and I have seen the second core is online and working but most of the time it is offline... better for battery life!
Working fine for me anyway with ARHD 3.6.7. Undervolted -50mv too.

Running stock ROM with faux123's kernel.
When CPU0 keeps staying at 1.5GHz, CPU1 still says it's offline.

I have the same, even when using the performance setting. Seems a bit odd, no matter what I use the phone for as soon as I open fauxclock one cpu is always offline. Did anyone have this on earlier versions?

I think that's just the aSMP architecture/Kernel. IRC the performance governor just fixes the speed at the maximum specified, it doesn't force both cores to be on.
I'll stick with 0.8.0, it does FC the first time after a re-boot but works fine after that. I like the screen off/on settings.
On another note I did find Faux123 0.2.3b9 best for my setup, lowest drain. I've not tried any other non Faux123 kernels yet.

same here...running 0.8 with intellidemand governor
i`ll test and see how performance is
second edit: why is fauxclock so underground.. isn't there an official thread?

I think it was all tied in to the Faux Thread. Since he's unfortunately stopped working on Sensation Kernels that thread has been closed.
Look in: http://rootzwiki.com/topic/4550-app08-beta-snapdragon-dual-core-oc-control/
TBH, I don't even know if it's compatible with other kernels, don't see why not but never tried. I guess the GPU and UV setting might not work with non Faux kernels.

Isn't this the same if we lower our frequency to minimum when the screen goes off. I am sure only cpu0 is used if its below 750mhz or so.

The G2x has no use for these quirks. Nvidia has some special battery saving things in the phone. That's why our phone does not use CPU governors. Just use the phone as is. You can over clock but don't set CPU profiles. The nvidia chip does everything itself.

Thanks for the info, I never knew that, coming from other Android phones. I was wondering why no kernel had CPU governor options enabled.

sorry man but the apk was takin down for a bit.. somthing about the PID making the app shutdown after being off for so long. script still works, and is recommended for now. ill post when apk is back up

thx also what are the permissions for the script cause im using root explorer

which kernels do this already?
I am pretty sure that I was running on only one core when on Trinity ELP when setting it at 750 MHz and lower. Also, the newer Faux 050b6 through 050b9 go to a single core limited to no more than 503 MHz whenever the screen is off.
Is anyone aware if the Trinity T15 shuts down the second core ever?
How about the stock LG or standard CM kernel?
How about Faux's kernels for stock based ROM's? I have recently been on Kwes and Buru stock 2.3.4 ROM's using Faux 014b2 at stock voltage. If I keep the MHz low, I swear my battery performance is better than it ever was using undervolted ELP on CM7 based ROM's.
I just did 35 hours :victory: of moderate usage (about 2 hours talk, 3 hours wifi web, 1 hour text) and still had 45% left in the tank! - With the stock battery that's nearly a year old now...:good:
