[Q] Quadrant Benchmark Frequency changes 400, 600, 800mhz but never 1Ghz?

Hey all,
Noob here, i noticed under "current frequencies" in the Quadrant Benchmark that it jumps between 400 and 800mhz but ive never seen it at 1000mhz. Is this normal or should i bring it to the sprint store to get it checked out?
Thanks!

Quadrant probably doesn't need the whole 1000 mhz to complete its tasks. You should instal set cpu and set it to performance mode and then try it

hmm im currently running stock, i need to be rooted inorder to use setCPU right?

that's right.

News flash: Quadrant sucks and is woefully inaccurate, use SmartBench 2010 or GLBenchmark.

Yes quadrant sucks. About your question... It shows the frequency that it's running at that time. It's not made yo run at 1000 all the time for battery purposes. When u start quadrant, since it's an intensive on your CPU, I'm sure it scales to 1000. Mine didn't used to show 1000 either until I starting using CPU tuner.

yeh, i know watcha guys mean, thanks!

Under volting

Okay so I'm pretty much familiar with the whole oc situation that's pretty much putting the phone anything above 1000mhz right?
But what exactly is uv? I thought it was just having the maximum below 1000 but it seems there's a way to go a lot lower than that?? I'm not sure if I'm just confused or what's going on.. but I seen ppl saying things about having their phones on stuff like -125 to 200 mhz or something like that
How could u go negative or was I just not feeling well when I thought I read something like that..? Can anyone help me out please lol

oh my gawd noob......just kidding
Overclocking pushes the cpu frequency aka speed.
Underclocking limits the cpu frequency.
Overvolting pushes more voltage/battery to the phone to stabilize/add preformance, however there will be more heat and more chance of ruin.
Undervolting takes away voltage to help lower comsumption of battery and in some cases helps the cpu run cooler and faster or even more effieciently.
How To:
Download voltage control from the market. Open it, and go into the voltages tab. Press the frequencies that are empty. You can tap the whole thing and it will bring up the bar for voltages lower it on free version or add voltage on the paid version only.

undervolting is all about getting the least battery drain on each frequency. -125 means they are running 125 mV below stock. The downside is if you run to low it will freeze your phone and you may have to do a battery pull..thats why i dont go above -25 on 900 and 1000mhz but can get -125 on 200mhz. I disable 100 mhz because my phone has problems with it and havent seen any difference in battery. Each persons phone will be different, some can only do -25 on each frequency. Download Voltage control and toy around. Just dont SET AT BOOT until you've used the settings for a few days.

And be careful... setting uv too low can cause in erased data and dat corruption... and that includes your sd card!!!!

Thankss everyone
I use setcpu now I used to use voltage control
I tried once messing with the upthreshold or whatever that is and messing with frequencies but ill see what I can find out on my own
I usually don't mess with any of the advanced settings or frequencies
I just always sent my phone to like 100-400 mhz when I'm not really using it
And 400-800 when I'm actually using it and it always runs smooth and nice but if there's a way to make it save even more battery and still perform well then I wanna find out lol

Voltage control

Can someone give me some good settings for voltage control. I'm on ACS ICS samurai assassin. And get a better understanding of it. I use my phone to play games text surf web and watch movies.

This is going to be a long post........
Once downloaded there are a lot to do but in general there are i/o schedulers I think that's how data is handled Idk google is ur friend. Anyways govenors handles the cpu and "governs" the frequencies it needs to be pushed to depending on what the kernel is telling it via touch input wifi cell signal etc etc. And on the sliders are the frequencies. The max is the max amount the cpu will be pushed and the min vice versa. In the voltages tab you use these to disable or enable frequencies..... tap the grayed out cpu picture.... to enable.... then you tap on the numbers to open the sliders and this will allow you to undervolt this takes the stock voltage your battery puts out and lowers it to put out less battery. For some guidelines ill post what I use but every phone is different.

Not all phones can handle that UV though, it might freeze some and obviously doesn't freeze yours. Hell haha mine can past that haha. But still some can even UV a lick of -25

Yep on froyo if I tried to uv 200 to even -25 my phone would instantly freeze... now on gingerbread I can uv 200 -175 (and probably more but haven't tried yet!) And it is super stable... my bros epic cant uv past -100 at 200 so every phone is defenitely different...

Lol... my bro got this phone after the update to gb (about a month ago) so I will have to have him go back to a froyo rom just to see if he can uv froyo better or worse... I guess curiousity is gonna get the best of me!

Tegra 3 and SetCPU

Does using setCPU with the Tegra 3 and it's 5th core muck up the Tegra 3's native power saving capability (ie. using the fifth core as a low energy solution for minimal activities)?
Has anyone seen tests of battery use with and without?

What I have seen from my use over the past week or so with SetCPU is that you can set the governor and the minimum clock both of which have an effect (although minimum clock is not strictly adhered to).
I don't believe the 5th core is exposed to the android OS so SetCPU shouldn't effect that at all.

I'm testing the beta and no it does not effect the max 100% of the time the tegra power management seems to kick in. I have informed mike (setcpu author) about this issue he is looking in to it.

I guess set cpu is not supported quad core yet

As James pointed out, the 5th Slave core is Transparent and not visible to Android, so it 'shouldn't' be effected by SetCpu

It supports quad core CPU scaling, the question is about the 5th core.
That the 5th core is invisible does make it seem like it wouldn't effect this issue, however I would like to understand a bit more about how it works to be sure.
From what I understand, when processor use is low and the CPU is scaled below 500mhz(?) then the 5th core alone is used, whereas at higher frequencies the other 4 cores are fully engaged.
I would just be worried that setting the CPU speed through methods other than whatever method HTC/nvidia had arranged for might negate this benefit. It'd be good to know from the setCPU guy what's going on, since he likely understands a lot about how CPU scaling works...

Here's my Feedback on using SetCPU with HOX:
When trying to underclock my phone
Max: 1000 Min:51
Result: rebooted within 5 minutes and then kept on doing this untill I reset the SetCpu settings to phone defaults and uninstalled
similar user experience here: http://forum.xda-developers.com/showthread.php?t=1596992&highlight=setcpu
I have seen that there is an app created for the HOX:
CoreControl: http://forum.xda-developers.com/showthread.php?t=1652136
I want to give this a go and I feel this a relevant topic to be stickied maybe under a different Topic Title ie. Custom CPU settings
Will install CoreControl and revert...
BTW: what settings have you tried using with SetCPU to underclock that doesnt result in a random reboot and that works, also what version of setCpu are you using

system tuner will allow to set the clocks for T3 properly

CoreControl is for enable/disable cores, not for overclock/underclock, I've been using it for a while, at least my HOX doesn't heat up much

I can now concur with @vegasphinx it doesn't heat up as much and I dont notice the difference besides the toastie popping up every so often saying CoreControl has been granted SU
can any of you give me an idea how to setup the Battery Stats within CoreControl

It crashes because there's no kernal that supports overclock/underclock.

Downclocking to save battery live?

Hi,
I am running a wicked v2 rom, had an idea yesterday to try to downclock cpu to potentially increase battery live. Used SetCpu, set ut to ~1.4ghz, governor is powersave. No performace hit that i can notice, outside benchmarks. On my first day now, will see how it works out. Anyone done that, any statistics?

ive been doing this since the first custom kernel was released. you get a few more hours depending on how much you downclock

downclocking always worked on my nexus 4
On a side note doesn't the powersafe governer set your phones cpu to the lowest clock speed at ALL times. As in if your minimum clock speed is 300mhz then its going to set your phone there forever?

just curious why you would buy a phone with 4 cores clocked at 1.9 ghz and dropping it???
thats like buying a 500 horsepower car, and detuning it minus 200 hp... whats the point?? Im not cracking a joke, its a serious question

Well, the plan is to get a zerolemon battery when it comes out. And i really cant see and performance hit, otherwise i would not really sacrifice... Assuming performance doesnt suffer, why not squeeze some battery life out and run a phone cooler?
