I just got my nexus 7 five days ago and before I got it I say it was 1200mhz but when I got it rooted it set it up things in setcpu it says 1300mhz(stock ROM stock kernel) but it doesn't actually work at 1300mhz only 1200. So is it 1300mhz or 1200mhz and if it is 1200mhz is it supposed to be able to go to 1300mhz?

The Tegra 3 T30L in the Nexus has this info on Wikipedia:
1.2 GHz Quad-core ARM Cortex-A9 (up to 1.3 GHz in single-core mode)

So I assume that's why it is getting reported as 1.3GHz.

-0.25mv / 1500Mhz gives more quadranet vs stock 1400 mhz and stock voltage
how healthy to keep it this way? any risk go up to 1600Mhz?
on last Omega JB rom i went from 4000 to 5130 in quadrant using this OC.
Thanks!
Of course higher clocks gives vigher benchmarks. Uv doesn't affect unless you uv to the point that voltage can't keep cpu stable.

The question: 1500-1600 levels risky to CPU ?
UV lower is good to keep temp lower...
From my experience, undervolting offers no benefits at all. Temperature remains the same and battery seems to be worse when idling.
with no overclocking and with stock 4.1.1 li7 i have 6300 scores in Quadrant..... with overclocking to 1600 mhz i reached 6700... no sense to overclock it

Which rom you use ?

Learning time!
-UV provides stability, its not to save battery. Its such a miniscule amount of volatge it wont mess up battery life, but it will help stability of the CPU...
-And when you OC, you need to undertand that it doesnt stay at the max speed on all four cores all the time. It changes to fit the needs of the user.
I think the CPU can reach 2.0GHz easily, i mean my single core Captivate with a Hummingbird 1.0GHz ARM cortex-A8 could reach 1.92GHz and stay stable with -50mV UV.

Hi, 1200mhz vsl60 is enough. Or you want kill the lifetime of your cpu and over this the battery drain empty before the handy is on.

Defy and Defy+ have the same CPU but different kernel (which is software). The kernel limits the clock. Defy+ stock gingerbread kernel adds Clk4 and Vsel4 which are 1 GHz and 58 Vsel by default. I have a Defy+ overclocked to 1.2 GHz Vsel 60. The clock is limited by the kernel and Vsel by the hardware. My hardware at 1.2 GHz is stable at 60 Vsel, yours may be stable at 58 or 62. I know some people OC their Defy at 1.4 GHz but they set a dangerous Vsel to be stable (70 and above). 1.2 GHz is enough.

You can try it yourself. The max I've gone to is 1300 MHz/ 68 vsel... battery heat was very high at 68... many others have also tried, and get the same result as I did.
But as they say, experience is the best teacher, so you're welcome to try it out yourself, and let us know.

So u ve over clocked to 1.4 GHz o reduced to 1.3 GHz ? I really don't understand y defy+ can't be OC more whereas defy can be as it can also reach 1.2~1.3 GHz ...... buying defy would ve been better I guess .....

are you really telling me that you find a difference in 1.2 ghz and 1.4 ghz, while you're using your phone? all you're doing is encouraging battery drain and more wear and tear on your cpu..

Ofcourse there is a huge difference betwn 1.2 n 1.4 GHz.........its all about processing speed which matters for smartfone users ...... Y would there be 3 ~4k rs difference for an 800 mhz n 1GHz cell phones?

Defy and Defy+ have the SAME CPU, but Defy+ is clocked at 1.0 GHz by default.
Cost difference is also for bigger battery and better camera

How high can you over clock your phone? Like is there a limit to it. I know our nexus 4 is clocked at 1.5ghz but is our processor bigger?

you can overclock it how ever you want, if you build it into the kernel. the real question is how much can your device handle. some can oc to 1836mhz, even less to 1944mhz.
Highest OC I have seen (and tried) was 1.9 GHz. Even then, if more than 2 cores enable at that clock, the phone crashes and does the red light. IMO you don't need to OC the Nexus 4 anyway

Weird. I used faux's kernel to OC up to 1.9 ghz "just for fun". Even made an antutu benchmark. Nothing crashed.

not a "real" 1.9ghz, the rest of the reply im sending you via pm
Ive been getting smoother results underclocking the G2 at either 1.7 or 1.9 and knock on seems more quick to response, but when I tried video recording the 60 fps isn't smooth when you are clocked at the regular speed.. beware...I ran a benchmark on quadrant standard and got 17,250 constantly so it is underclocked per core... I want to hear your opinion on this and do you plan to underclock or already are. I feel like the ability to be more smooth within the UI helps a lot more now..let me know your thoughts!

From using trickster mod and setcpu to underclock they only underclock cpu0 the other three still use the full frequency range.

You're saying that by underclocking, you're getting a smoother UI but lower benchmarks?
No i got a higher benchmark than the guy who replied on my post. I did get a smoother UI and everything is less laggy. Ill post a pic of 2.3ghz idk if its actually at 1.7ghz or 2.3ghz ill do another test

I am tending to believe that the regular clock speed is actually overclocked...just like how the galaxy s4 is overclocked 200mhz more than normal...however I could be wrong..
If you really want to see if this odd issue is actually happening download an app called Multicore CPU Control (the only app of its kind that seems to work with the LG G2). I use this to save battery by turning off all but one core, but it allows you full control over all your cores.
Download it, create a profile, and set each core to what you want. I had to save the profile first, then go back in to edit the latter 3 cores' frequencies.
I would suggest setting the min and max to the same and choosing Performance for the governor. Use a different app to set the scheduler.
Be sure to have something like Kernel Tuner to ensure that all your cores are running as you intended. If not, go back into Multicore CPU Control and re-save your profile again.
Would love to hear the results afterwards!
I used Multicore CPU Control.
The only way to set clock to CPU 1,2,3 is let them always active. If I leave dynamic for these cores, they still go up to 2,26 GHZ. I think this the reason why HeXaLox have a little decrement when underclock because it only did for one core.
Hi all
I just want to ask
Can someone please OC matrix v12 for
Me
Cpu to 1.8 GHz
Gpu to 5xx MHz
(please don't ask why.... If don't want to help then goodbye)
A) us neo kernel it's based of matr1x and allows overclocking to 1.7 GHz previously it would let you go up to 2ghz. B) The nexus 4 gpu hasn't been successfully overclocked past 487mhz yet, there was a 533mhz overclock but it didn't work and gave the same performance as 487
