Quick system info

Anyone notice in the quick system info the processor says armv7 processor 662mhz. I assume that's just an error and its really 1ghz right?

I believe the phone has something similar to Intel's Speedstep. At idle the processor speed drops way down and it only increases as far as necessary so as to save power.

The CPU is automatically scaled as demand/load increases. 1ghz is the max when under heavier load, so it's to be expected that it would be running at 662mhz when you bring up system info. Don't worry... that's normal.

well i refreshed it like 20 times, I even see it hit 162mhz

how about free memory? I had a ton of apps open it said 20mb free is that normal?

BogoMIPS is NOT the same as MHz on the Nexus!
Multiply that 662 by 1.507!

ohh ok lol

Undervolting Thread

This thread has been created to share Undervolting Settings (UV).
Undervolting makes CPU/GPU/Modem to consume less power, thus extend battery life. This is allowed by flashing modified kernels that allow UV (Thanks to raspdeep's work). One can use Voltage Control to change settings (Thanks to xan).
Setting format is -x mV for a given CPU clock as used in xan's app: [1200Mhz] [1000Mhz] [800Mhz] [400Mhz] [200Mhz] [100Mhz]
What are your settings?
PS: Please edit your very first post with settings instead of reposting. Thank you!

Stable: 50 50 75 100 100 100
1200 max: 50
1000 max: 50
800 max: 75

I am currently running 50 50 50 75 100 100 with no stability problems. It has made 4 back-to-back quadrant runs and a couple days of general usage without any crashes so far.

Undervolting doesn't work well with my phone the same with overclocking. I can't undervolt 1000Mhz and above because it causes much stability issues here. I can only undervolt 100-800Mhz with settings < 100mV.

My system hangs in sleep mode when I have setCPU or Superpower with sidekick on.

I have the max cpu capped at 800mhz using SetCpu.
Undervolted -50 for 800mhz 600 400 200 and 100 each.Phone was at 50% last night and 6 hours later it's dead.Battery was completely discharged.All i did was set everything at 50Mvs less.Correct ? i think i'm missing something.Do help.thanks.

Negative effects come in the form of stability issues and random reboots. Is doesn't physically damage the processor. By lowering the core voltage supplied to the CPU, you also decrease the noise margin for the CPU to properly differentiate between logic 1 and logic 0. This is why -75, for example, works for some and not for others because processors are not 100% identical. The obvious benefit UV is lower power consumption.

I'm also using Tegrak's overclock apk for some time now (from beginning) and it's really good!
Just lower the core voltage (start with cpu level 0) until it's unstable (random reboots), then add a few mv (+5) to make it stable again (no reboots). do this for every core frequency (only one at the time, so you know witch one is making the system unstable). I never touch the internal frequency... Undervolting will NOT damage your CPU (overclocking can if you're not carefull)
Don't be stupid testing just a few hours, test (stress test) for days. Only then you are sure it's stable
These are my settings:
(rock stable after a few weeks => playing asphalt6, running quadrant and smartbench hours a day for a few weeks,...)
cpu level 0
frequency 1000
core 1205mv (-70) => could get it stable at 1200 but had one reboot after one week, so I added +5
internel 1100
cpu level 1
frequency 800
core 1105 (-95) => could get it stable at 1100 but had one reboot after one week, so I added +5
internel 1100
cpu level 2
frequency 400
core 950 (-100)
internal 1100
cpu level 3
frequency 200
core 825 (-125)
internal 1100
cpu level 4
frequency 100
core 825 (-125)
internal 1100
Now I know what my lowest core voltage is, I can start overclocking (not for now).
I'm on stock deodexed JVP 2.3.4 with Hardcore (latest) Speedmod (partition EXT4), Tegrack Overclock Ultimate and Voodoo Control Plus (holy combo => Quadrant 2400+ (no OC, just UV) and wow, what a great battery life!
edit: yes, I need to update my signature

^ Typo??????????
internal voltage @ 100Mhz is 1000mV by default, so you are overvolting.

Default value is 950mV on my phone according to pimpmycpu. According to SamHaLeKe's post, he's reducing his by -125 so 825mV is correct
I'm new to UV, and just experimenting. My current values are
1200 = -50mV
800 = -50mV
400 = -100mV
200 = -100mV
100 = -150mV
Seems ok so far, more aggressive cutting gave me reboots

$$$

The most i could get from my phone w/o stability issues
1500 - 50
1400 - 50
1300 - 50
1200 - 50
1000 - 50
800 - 75
400 - 100
200 - 125
100 - 150

Starting from 1000MHz, I'm using these values :
-50 [1000]
-75 [800]
-100 [400]
-125 [200]
-150 [100]
No stability issues since then !

Mine are;
1000 : 50
800 : 50
400 : 75
200 : 75
100 : 100
Works great for me

my phone now cold as ice. and greatly stable

I'm a noob at this UV stuff but I'm quite interesting about that.
I tried with Control Freak, should I set first a low voltage on 100Mhz and try to stress the cpu only with this change on 100MHZ? or should I set all voltages and test?
thx for help

1200Mhz 2700 6200 1120 4380 40
maybe there could be another mode that will use
500mhz most of the time [for normal using or one app using Cpu]
and when playing or using heavy 1000Mhz
[Dev]
i see that memory score is not linear
maybe could fixed by our greatest devers

I hope u do understand that these results are total bullcrap.
The newest dual core chips dont even get 2.7k scores in that benchmark.
Something in the desire HD build farks up the scores simple as that.

If you look at the quadrant advanced score, you'll notice it only gets those scores because of the I/O score. The processor one is about the same or a little more than teh Nexux 2.2, so if you underclock to 500 mhz you may get a total of 1600, but your processor score will suck badly and your phone will lag and really suck.
Keep your max at 998 and your min at 245 and use smartass and you should be fine.

My HD2 has been running smoothly with 245-998MHz smartass for weeks now, battery life has been great too.

Quadrant scores are useless. RUn it, then run it again, you'll get different results.
I don't use SetCPU at all, it's just not needed.

According to my Quad Test im getting a total of 2196 with 245-998mhz with smartass on SetCPU my CPU: 4450 Mem: 1127 I/O: 4716 2D: 273 3D: 412 Work that one out

Nice!! Btw, I think you gotta try the the Linpack in multi-core test, too. It should show score of more than 150+ MFLOPS, may reach even 250!!!

That's not something I would do.
say (3+3+3/3)=7 and that's not average.
it should be ([test1+test2+test3]÷3= End result)

You mean do the "+" math and "=" before using "÷"?
Because thats how I did.

[Q] OSD cpu measuring app

Hi guys,
I'm trying to understand how and how much thermal throttling influences my LG G2 performance while using games; to achieve this I need some app that can show me, in real time, osd on-screen-display while I'm playing, the usage of the 4 cores of the snapdragon800. I'm more interested in their frequencies than in load percentage.
I tried to search on the web, but I didn't find what I'm looking for, but, I saw a video (this: https://www.youtube.com/watch?v=J6Z6_nx1bUU ) in which there is exactly the app I'm searching for (the one on top left "multicore usage" ... I don't know if other boxes are from the same app).
Someone knows this app's name? or can recommend me an app with the same features?

Hey!
While I don't have the knowledge of an app that does exactly what you want, I've read countless times that the SD800 starts at max load and then throttles down as the CPU gets hotter. It would be interesting to see exactly HOW much it uses.
What I've done, though, is to start playing Asphalt 8 and having a CPU monitor from Android System Tuner on my home screen. I'd then play a bit, then quickly go home and open the CPU monitor. First 5 minutes it was at 2.26Ghz, then it throttled down to 1.95 Ghz and finally after about 10 minutes it throttled down to 1.72Ghz.
Now these times arent quite precise bit it should give you and idea of what to expect. I'm more than interested in hearing what kind of results you get, so go for it!

I'm doing a similiar thing with Trickster mod to see how much time is spent on every single frequency... but it's very difficult to understand something in this way. The only thing I can say is that my snapdragon800 throttles like hell....
In 30 minutes playing:
only few seconds at 2265, 1958 and 1728 MHz (the same for 960 and 1190 MHz... I think this 2 frequencies are unused in playing)
2 minutes maximum for 1574 and 1497 MHz
Most of the playing time is at 1036 MHz and 1267 MHz....
But, generally I can't say at what frequency Thermal throttling is influencing smoothness.... this is why I need some app like computer programs such as atitraytool or msi afterburner... this is the only way to understand precisely.
However, I discovered that the benchmark used in the video of the first post, is a "Qualcomm" tech demo with built-in osd... but I'm unable to find and download it

What PVS bin is your SD800? You can check that in the hidden menu.
Keep in mind that there's another factor to determine the smoothness which you shouldn't forget - The frequency of the GPU. It might be interesting to monitor that too.

Hey for now you can try cool tool from play store which won't give multi core stats but it does display the constant change in frequency

Well PVS is basically how "good" your chip is. It is a scale from 0-6 where 6 is the best and describes how many volts your chip needs to achieve maximum frequency.
You can check it by entering (on a D802)
3845#*802#
Then go into "Settings" AND "Version Info" - scroll down and see.
Naturally, the lower your PVS bin is, the more heat your phone will produce since it needs a higher voltage to acquire same frequency. This also means more throttling.

It's 4
I think it's quite good (infact I have -50mv, that is 2 steps less with trickstermod, on every frequency)
However, I found "PerfMon" here in xda... that has a floating window that monitors every single core usage and frequency (just a pity it doesn't monitor temperature...)

Also I noticed that gpu stays at 320MHz max while it should be 450 (in trickstermod it's correct)
Performance "gpu" governor works (but kills battery staying always at 450 MHz)
Simple_OnDemand "gpu" governor gets phone into bootloop

cpu throttles at 75c first ti 1.9 ghz, as the phone heats up more it will drop to 1.7. Phone will shut of at 92c.
and yes i got to 92C turning off throttling on CM and running antutu, wouldn't advice it ^_^

Weird. I found my cpu being throttled down to 1.57 ghz @ 69 degrees. Mine is pvs bin2
