[Q] SetCPU settings for Epic?

Being new to the Android world, I'm a little unsure of what my settings should be for SetCPU on my Epic.
Looking for something that would offer a good balance of battery and performance without crippling the device too much.
Thanks in advance...

I keep mine short and simple. I am using a kernel at allows for overclocking so I set the max to 1.2Ghz and the min to 200Mhz. You can play around with the scaling to see which governor works for you best. It's really up to your butt-o-meter.
Under "Profiles" I have one single profile for "Sceen Off" that keeps my EPIC at 200Mhz when the screen is off.

Your epic doesn't freeze when you do that? No matter which kernel I use, if I set it so that my phone down clocks when the screen is off it freezes. It won't unlock and the only way for me to be able to use it again is to pull the battery out and reboot.

I set mines to min 100 max 1200 conservative scaling and its been almost 48 hours and I have yet to have a lock up or freeze up im using the Stoopid fast kernel posted in Android development, set cpu 2.03 and AOSP OC v2 ROM

Nope. Seems to love it. I guess my EPIC and my EVO share their love for UV + underclocking maybe they really are related

I keep my Epic 1.2 -600 , I'd recommend the Stoopid Fast Kernel as well. The phone is still quick and phone is better with battery life and a hell of a lot quicker when it comes to charging.

I have mine set to 100 Min / 1200 Max. No problems that I can tell.
MixUp kernel.

What about the advanced settings? Can somebody explain to me what they are for?

when i input my own settings it wont show the settings. it just says 1 if at max and 0 if anything else. i love the app i just dont think its really working. i'm wondering if the kernel i'm on allows it to change cpu speeds.
running suppernova build 1.5
kernel 2.6.32.9 (not sure what that means)

i was always told to leave it on concervative scaling for sgs phones. Conservative won't allow my phone's screen to toggle on if my max is over 400. If i set it to ondemand, it works just fine at 400mhz.

I forgot where I read it but it was when I sold my Evo and moved to this section of the forums. I'll look around some more and see if I come up with something but I thought it was something like "Until Froyo gets officially released Set Cpu can't work with it. I bought set cpu a long time ago and didn't use it since. I'm about to throw that bad boy on though to see if it makes any difference.

It's not that SetCPU doesn't work with froyo, but the stock kernel on froyo already scales between 100mhz to 1000mhz without it. I do not have it installed and when I run a system monitor mine usually idles between 200mhz to 400mhz and ramps up whenever a notification comes in or syncing starts.
Just did a screen cap and the phone it idling at 135mhz.

thats true.
also. setCPU messes with your 4g connection to connect. i wasent able to connect when i turnned on the setcpu but i was on the stock conservative setting. i think 4g requires alot of cpu usage that setCPU dosent recognize. SMH

G2 benchmark... numbers sucked!

Just flashed enoms g2 rom and I cleared up what I can, tried making it efficient.I ran some benchmark tests on quadrant standard and was kinda disappointed in the numbers. My bests score was low 1100 after that it was 850,900, 835... very basic stuff any suggestions???
Sent from my T-Mobile G2 using XDA App

If you ran the benchmark on battery power, try plugging the phone in. Sometimes the CPU will underclock itself to save power. If that doesn't work, download SetCPU (google it) and make sure that the max speed is set above 800 MHz.

On the stock G2 ROM I was getting 1600-1800... maybe it's the ROM your using

Yeah this is the typical range for a stock G2.
Those scores in the OP are so low, its almost like hes underclocking or something. Or possibly a running application using a ton of resources?

i got 2064. but i was running virtuous.

im running enom's rom and i had it underclocked at 768 and i was still able to get 1609

Perhaps the kernel has an undervolting profile built in and it's triggered by a < battery percentage?

What should I have my phone clocked at with enoms rom?? I dnt have much running at all I dnt understand why its so slow, I was gunna flash the latest kernal and try that... clock settings please anyone
Edit: jus tweaked my clock on spareparts. I switched cpu governor from ondemand to performance and the clock setting. I put underclock at the lowest and overclock at the max highest... benchmark test put up a 2200... I feel as if this will drain battery like crazy only time will tell... what do u think, should I drop the overclock? Is it safe at that high number???

If I run with Flippy's kernel, CM 6.1.1 Stable and OC my phone to 1.8 GHz, I can get a Quadrant score of 3037 (screenshot below). With it OC'd to 1.4 GHz (my normal OC setting) I can get around 2500.

If I'm averging 2500 I'm fine wit that my current settings are Enoms Rom
Using enoms cpu controls
Cpu governor: performance
Max frequency: 1,516,800
Min frequency 245,760
I dropped 3 percent in battery writing this message.... my main concern is battery and overworking the cpu.... I'm thinking about downloading set cpu and clocking the performance settings then set it for power save after a certain drop point........ does this sound logical?
Sent from my T-Mobile G2 using XDA App

When you set your cpu to performance it means your cpu will stay at max all the time and it never goes down which is why you are getting bad battery life.
There is no need for that.
Yes you can do that with setcpu

[Q] Low Quadrant Scores

I know that this tool isn't a good indicator of performance... but when I see other people with the EVO getting 1200+ and I am at 800-900, I am starting to wonder if there is a setting wrong. My phone occasionally feels sluggish. Any idea's what the cause could be? using an AOSP rom with Tiamat Kernel

Have you ran it off of a fresh reboot?
I find my best scores were when I rebooted let it sit for 3-5 min after reboot, and then fire it up.

Trying it again after the phones been on a few minutes.
I used to use SETCPU and I thought maybe that screwed things up

If you want to increase scores why don't you put your Max frequency at 1190 and min at 1190 with setcpu. High scores are a thing of the past.

That is with my CPU at 1190. I am not trying to get a high score, but a score my phone should be able to get, you know? I see someone with an EVO get 1500 and then I am thinking something is wrong with my phone... I have the same phone..

Putting stock in scores is foolish though. 936 does seem a Tad bit low for sure. My set up is cm7 #36, tiamat kernel 3.3.5, JIT on, setcpu 1113 Max, 422 min smartass governor. I just ran a linpack and got 37mflops and 1200 in benchmark. This is the same set up I usually run on any rom or kernel. I try not to clock so high because it just drains battery. My evo actually can perform flawlessly clocked at even 998mhz. The only thing I notice different is that scores change and I don't really take a performance hit. Underclocking is the new overclocking lol. My last suggestion would be to play around with different kernels to achieve what you desire. Try savage zen!
Edit: just ran these 2 test just for you right now. Same results and I'm using same kernel you are.
~ d3rk

Run, it once, and then run it again right after w/out quitting. The if you run it multiple times (at least on my phone), all subsequent scores are on par with the second one which is usually 1-300 more than the first. Won't mean anything any different, but at least you might get some higher scores.
Also, you might need to try some different kernel combinations as well as different clock speeds. Mine usually does fine at 998 sometimes even at 921, but if I go too high it will start to slow things down. If you're not getting good results at 1190, try backing it off one setting at a time and see if you can get improved scores.
As far as comparing to other phones, even of the same make/model, you can't really do that. As long as they're in the same ball park, within a couple hundred, you're probably OK. Every phone reacts differently.
It also depends on the version of quadrant. You def can't compare diff phones running diff versions. I usually don't use it to compare to other phones, just diff setups on my phone. I know if I'm getting 1200 avg and then I all of the sudden flash a ROM and kernel and can't break 800 that something is probably wrong.
The most important thing is how the phone feels though. The fact that you say it feels sluggish leads me to believe you might need to try a diff kernel or see if something is eating up your CPU. Also, when you're over clocking, the min clock speed can effect your scores just as much as the max speed.

Ya give savage a go.

Ondemand governor

How to keep CPU downclocked? SetCPU gets pushed out of RAM...

Running Nottachtrix 1.2.1. Want CPU to stay underclocked for battery life...lasts way longer at 600mhz.

Use SetCPU to adjust the clock speeds.

System Tuner works very well for me.

Setcpu also. Never had issues with it.
Sent from my Atrix with XDA Premium

One issue that I have had with underclocking is that whenever I underclocked, the second core goes offline and stays offline forever. If you use system tuner, you will notice that the second core will remain offline unless you go back to 1ghz.

You only use both cores when you need it, and 99% of the time the Atrix does not need to utilize both cores. You will see them kick in working full time when using the lapdock. I use System Tuner with Faux 1.0GHz and mild UV on Nottachtrix 1.3.1. Everything runs fine as far as CPU utilization goes.

I know that you only use both cores when you need it but when you underclock to let's say 750Mhz or lower, the second core will go offline after a while and stay like that. If you play a game or watch a video, the second core will still stay offline and one way to find out is to go to the "Times" tab in System Tuner, and you will see that the second core has not been working at all even when you play intensive 3D games or watch HD videos. This happens only when you underclock.

If your phone isn't clocking to a certain speed, it doesn't believe it actually needs the second core. I think it kicks in after 800mhz or so

I believe the second core has to work when you are playing 3d games and watching HD videos regardless of the frequency. I basically want both cores to work at 750mhz but the second always goes offline and it never comes back. Even when browsing you can feel that its slower due to the second core not working.

[Q] UnderVolting.

I'm interested in undervolting my nexus 4.
My primary cause is to get better battery life and reduce heat.

Undervolting -25 can cause problems?
I heard that if you undervolt too much your device can be damaged.

You won't even notice -25, people usually undervolt -100 or more. I don't think it can damage your phone, it can only get unstable in which case you need to find stable voltages for your device (CPU).

These voltages are stable on my phone. Some users use even lower voltages on their "FAST" chip.
On stock ROM I did felt that phone is not as smooth as with default voltages but on Purity ROM which I use now I don't feel huge difference.
It does reduce heat if you undervolt enough.
About chips: Basically, when Qualcomm makes the APQ8064 chip that you see in our Nexus 4, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal, Fast, and Faster. The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. (Does this account for how some people's phones generate less heat? Maybe, maybe not. IIRC, there's like only a -100mV difference between Faster and Slow out of the box, however Faster CPUs should be able to handle lower voltages than Slow-type.)

If you want to reduce heat and save battery than undervolt your cpu.
Set -50 or -75 and use your phone (test it) for stability.
You can always set the stock voltages if you see that your phone becomes slower and you don't like it.

Just use your phone, play games, run some benchmarks, run StabilityTest app, take some pictures and or videos as well to see if there are any artifacts etc

What app are people using to undervolt?
I'm currently using SetCPU, but somehow i don't trust it to not mess with anything else, like the governor, ect; (any chance of that happening if i don't change anything?).

Trickster looks interesting.
As a question, how come you yourself use it over a more "common" app like SetCPU?
