Helloooooo community!
I have a question...
I'm using HD2 with nand android and the rom
MDJ's CyanogenMod 7 v. 2.6
I installed the SetCPU and I managed to OC my device @ 1536MHz
I stess tested and it is stable, plus I'm using it for 2 days now!
stock temps after stress test: 33c
OC temps after stress test: 35-37c
My question is, is it safe to leave it as it is?
Cause according to temps, I don't think I have problem...
Also my profile is "On Demand"
Max: 1536MHz
Min: 245MHz
Thanks!
Hi,
From what I understand, on demand will not OC your CPU to 1.5 ghz, but use the CPU according to the performance it requires. If you use really intensive apps, CPU *might* go to 1.5 ghz, but it really just raises about as high as what's being used. I wouldn't recommend 1.5 ghz OC on your phone for a long term use. You never know what might happen.
Alot of people do it though, but my phone isn't stable at 1.2ghz so I'm not one of them.

hi, i've got a htc wildfire.. well obviously considering i'm posting in this section
anyway, i've installed wildpuzzle 0.8 with the overclocking kernal, what i'm wanting to find out is....
when running setcpu, the cpu will change it's frequency depending on usage.
but what about if setcpu isn't installed and you use the rom to overclock to say 748.. will the cpu stay at 748 permanently, or will it drop down and up natively depending on usage, like setcpu does??
thanks
i would say without set cpu or a specific speed framework, it would revert back to standard 528max 480min
which overclocking kernel have you got, be aware that if you have 130 kernel and overclock, wifi hotspot will not work, you can see phone but you won't be able to connect, you need to use 055 kernel from wildpuzzle 8.0.11 thread.
a small side note, i have just recently changed my overclocking from 691max to 652max, no discernable difference in speed, linpack for 691mhz was 2.9, for 652mhz i'm still getting 2.8 mflops, but huuuuge difference in battery life.
691 max struggling to get 2 days, 652 max after 24 hours i still have 82% battery left.
how do you see this mflops thing? and is it like a cpu score?

Download Linpack For Android from the market, and, Yes, in a way, it is like a CPU Score.
You might have already figured out that HD2 can be overclocked as high as 1.5 GHz on its powerful Qualcomm SnapDragon Processor. Many people run their devices on default clock speed, but there are few of us who overclock their devices to get max out of it. So i have started this thread to know what your max clock speed is and what governer are you using. Post replies below. Also, don't forget to mention your Phone's Temperature if available.
Mine: 1.2 GHz On SmartAss Governer , Temperature Usually Around 95F

1305MHz using interactive, temp alway @ 28°C even when phone get hot?? tho alway careful to let it cool down when it feels too hot.
I have underclocked ... to 720Mhz (interactive)
Performance is okay and saves battery live
Temperature is about 28 celcius.
1267, 768 when battery less than 30%, 422 when screen is off
On-demand w/screen on, conservative when <30% and screen off
Not great on battery, but good performance an no wake lag
CPU Load jump or whatever it is, set to 30%

Sticks with no overclock
using a rom which is fast enough and saves battery life, Dont see a point that needed to overclock CPU
Undervolted to 576mhz, for better battery life.
Runs smooth enough for all apps, including navigation and games
No overclock for me, don't need it, phone is fast enough as it is.
Clock speed: 998mhz (default), governor: ondemand, temp: n/a
Good enough for me sweet onough on may battery.
P.s. there seems to be no difference(performance wise) between rafpigna kernel oc'd @1.5ghz and tytung kernel oc'd @1.2ghz, when testing on linpack and/or other smarbench tools
Will it damage my processor? I wanna use it but I don't wanna kill my phone!

No, it won't kill your phone but it will drain your battery freaking fast...
Yeah, prolonged overclocking will build heat and may damage your phone. And why do you want to overclock up to 1.9GHz anyway? There's no performance boost after 1.6GHz afaik.
Edit: maximum performance I get is around 1.5 - 1.6GHz average over repeated benchmark of different software.
I got my Virtuous finally at 1.7 GHz (yeah!) and team the Quadrant Benchmark and gained about 200 points more, but I got to agree: there is no performance boost which you can see without benchmarking.
So I will put it back to 1.5, that's enough.
Edit: WTF? I've put it back to 1.5 and got 100 more points than with 1.7?!
I'm using system tuner for cpu temps. Seems to be the most accurate reading.
My current kernel can OC to 1.6 GHz but temps get around 62c. On stock 1.3 GHz its gets to 52c max.
Trying to figure out what is safe before I mess with it any more.

I overclocked it to 1.6 GHz too and I have to say that you don't have to worry about this. With the Trinity Kernel, for example, you can OC it up to 1.7 GHz. These values were tested, so they are stable and safe.

max safe temp fot the nexus 7 is 100C. if you do reach 100C, there is a safety mechanism in place that will shut down your cpu. but before you even reach the 100C safety shutdown, you will reach the throttling temperature. it will lower your cpu safety, regardless of what you have it set to, to cool down your cpu. i think the default(stock) throttle temp is between 70-80C, i dont remember. but all the custom kernels have the throttle temperature set to what the developer wants, some higher, some lower.
62C is well within safety range, and within normal range for 1.6ghz. itl go even higher when the device is being pushed. i habe reached safety shutdown on many many occasions, usually when pushing the device very hard and intentionally at a raised cpu speed. ive also reached it while playing intensive games, for long periods, and overclocking my gpu. and thats another way to raise heat, overclocking the gpu. even slightly overclocked, the gpu can affect the cpu temperature very much.
Currently looking into the process of OC'ing and UV'ing. It would be cool to see what results you guys have got and what difference in battery life you perceive!
Im currently at stock ?

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.
Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.
(More is possible, but I nearly dont play games with my tablet)
With this I get about 8 hours of SOD time with Surfing.
When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

I know a bit how i can get to know my cpu's pvs stepping, but since you have the same as me, what is it exactly? And is it considered a fast, normal or slow binned cpu?

mine are way lower and im pretty stable, no crashes but i dont' play games
im on ElementalX oc to 1.728ghz

Whats the best way to test stability? Ive got this app https://play.google.com/store/apps/details?id=com.into.stability but i dont seem to get any wiser... Anyone know what i should do?

yup, run that for like 30mins on classic test, should be fine if it doesn't crash

I did that, but with voltages that are stable there, antutu crashes. And with voltages that are antutu stable, my device crashes randomly. I can run the scaling test with very low voltages across the board for more than an hour and it doesnt crash.
With other apps it just crashes.
This is an experimental undervolt that rarely crashes when switching apps:
I dont know which clock speed and its corresponsing voltage is unstable because the clock speed ranges from 384 to 1512 mhz and i dont have a crash log.
So I added 12.5 mV across the board, and this hasnt crashed so far!
But, being the perfectionist that I am, I want the Ultimate Undervolt. Is there a way to see what frequency you are running when it crashes?

I achieve stable 700mV at 1026MHz...
30mins stress run on "stability test" app and on stress run on "setCpu"
At 1134MHz the tablet freezes for the first time when I switch to 7875mV
Isn't it weird??
I dont think the stability test app is working. I could undervolt 1512 mhz to 900mV and have it run stable, but everyday use stable is with 987.5mV

Will you post your voltage table?
What are the Kernel setup settings that you choose and have you ever OCed to 2.2 and still get good undervolting?
