ive just looked at a phone tester app thing, and found out my A500 is only running at 480mhz, how come? tried couple other apps to check and not moved, it should be an 1ghz?
help lol
Like virtually all modern processors, the CPU in the Acer scales its speed to the current required load; running @ 1GHz full time would generate additional heat (and system wear) as well as reduce the battery life.
My tab tends to spend about 2/3 of its time @ 456MHz and underMHz, and about 11% @ 1GHz, the rest being spent in between (with very few stops in the 760/816/912MHz stages.)
If you have SetCPU (requires Root) you can fire up a reasonably complex game for a couple of minutes and check the Time in State info again.
Now, if this isn't the case, what specific "phone tester" app did you try?
Yeah you would not want your tablet running Max CPU speeds all day.

i understand about not running full all the time, but its a constant 430.39, it hasnt moved, even using a high end game or anything?
What's a high end game for you?
Because my tabled does go to 1GHz while playing Galaxy on Fire 2.
Get systempanel from the market and test.
If you are rooted, you can use the script i wrote to log clock speed and usage % of both cpu cores while you are doing something. I OC to 1.5 GHz and it is easy to crank both cores to to the max while watching a movie or even just browsing the web.

This thread is Meant to display my results from "battery" testing "performance" benchmarks etc. to show its fullest potential.
I've ran "quadrent, linepack and some other benchmark" results vary.
QUADRENT I usually get depending on how many widgets, background task are open about 1900-2300 and Used "SET CPU" To performance mode "926 MHZ - 1000 MHZ
Eagerly waiting on a OC For the tegra 2 chipset on the iconia "xoom" has already achieved great speeds of 1.5 (1500) GHZ
I made a short brief 6 minute video of me running a few benchmarks, to show the speeds it achieves. "video proccessing will be watchable in about 5 minutes"

Next test i will be running on this device is battery life, something lots of people are converned about should have results in qbout 48 Hours, will keep update will run many test on this device, from straight playing games battery life to just movies web browsing etc. the whole 9 yard.
Will continuasly post updates on new things i found out from overclocking testing everything you can imagine.
I also ask that we all as a community can share our expieriences with the device from batterly life to performance to enchancements.
"l3giticonia out"
Wow I wish you had kept this thred up I would have loved to see this before I purchased.
hmmmm
Correct me if I am wrong, please: but by using setCPU to set a "performance" option and setting the speed lower then stock clock speed (926 mhz?) you have now disabled the systems ability to lower the clock speed and are underclocking the system.
Am I mistaken in assuming that you are going to get rather useless data on the overall performance of the system by setting these options? By underclocking, you have installed a custom kernel on the device and any results you get are going to be subject to the performance of that kernel, which is not what the a500 stock is running.
Why 926 mhz? Stock is 1.0 ghz, I generally run at 1.4ghz+. Am I missing something? Again, by setting SetCPU to "performance" any data you come up with is going to be on a system that cannot lower clock speed during low use periods, so your battery life stats will be lower then a normal users experience.
ARM based chips are built to scale the speed depending on load. By setting performance mode, you disable the chipsets ability to scale, right?
I can set it as high as 1646. IV looked around and it seems that people use 1504. Is it unsafe to go any higher?
Thanks

1400 is safest I run Alexandra iii
if you go up to 1.6 GHZ, you might get SHUTDOWNS...
if you don't run any games, or apps, sure it will work. But not smart to overload it.
If on Custm ROM, Read DEV Notes, usually they'll say (or mention about Kernel changing)
as a rule I keep it on 1.5 Ghz (when 1.6 was max) (have tested on about 8-10 diff roms) (never have had any shutdowns yet)
*** also maybe use a meter app to check TEMPS (like battery TEMP)
Cool Tool - shows battery temp, RAM, Proc Freq, + more in little box on screen all the time (adjust settings)
https://market.android.com/details?id=ds.cpuoverlay
"setCPU for Root users" - underclock to lowest when off, set lower cpu freq if battery gets warmed to ur custom Degrees)
http://www.setcpu.com/
***Some custom ROM's have thier own Freq CONTROLER app (that could clash with prog or have 2 progs do the same thing)
Like humans NO TWO CPU's are equal
All of the above it true with one exception..NOT every cpu is created equal Not all ram chips and so on also live up to this..
Start over clocking your cpu slowly. as you push clocks higher of course lower voltage. This keeps heat down .
Two processors even made on the same casting can be totally different . Where one will take more heat with less errors and corruption and the die next to it will almost crash running its designed clock speeds . Being that extreme is very rare with a few exceptions. most are close as to a common ability. within a few 100 mhz.
So the answer is there is NO TRUE Answer. its trial and error but on the side of caution and testing clock speeds and heat is not a 30 second yes it runs. Do it over a week or so. I know with my dragon cup in cell phone its at its end of life from being over clocked for a few years. some last longer some die quicker.. Its kinda like drinking on your brain the more you drink the more cells you kill.. The hotter your cpu gets the more transistors fail the slower it becomes the more errors you have .
Relax .. go slow.do not expect to get what everyone else is claiming. and you will be fine..
Sorry again for long winded post..

Any is unsafe. Higher speed equals heat and heat kills semiconductors. Might work for a while but why risk it
My daughters has been running at 1.6GHz for 2.5 months without any crashing or blowing up.
I say at 1.6, you're starting to enter the "red zone", sort of asking for problems. Why go up that high? I mean, 1.5 shows enough performance improvement over the 1GHz...
I was watching Netflix with HDMI plugged in, brightness all the way up CPU Max 1.5 ghz on demand governor. I set it down on the couch and when the movie was over I picked it up and it was scorching! I looked at my antutu widget and my internal temperature was almost 120! And the aluminum back doesn't help. Has anyone else got their tab this hot??

No, but your usage case is probably detrimental to the device. My suggestion is to not crank it up to 1.5 when doing task that will make it stay there for over an hour.
Agreed... a 50% overclock is in now way called for to run Netflix. In fact, if you playing around with CPU speed, I'd suggest trying to underclock it and see how things run. Less stress, lower heat, longer chip life.
Highest my A500 ever got was 96 when I accidentally left it running youtube under my pillow. Do you need the brightness level to be that high while watching it on TV?
Does anyone know if there is an app, or modified version of CyanogenMod's Performance Settings that allow users to cap the cpu speed per app?
I am asking this because when I play some old school games with RetroArch or running any other games, I know the application can run smoothly with, say 50% of the speed, however, the phone would go all the way up to the max speed and drain excessive battery over time (especially when we play games with it)
With the PAC Rom i was able to monitor the CPU cycles of the phone (didn't have this tracking feature on my old phone's CM). Here I've attached 2 screenshots to show you what I mean...
One of them I capped it at 1.3ghz, the other one is at stock max speed. Both running the same game for a little bit doing similar stuff.
I think if we can have per app CPU speed cap, we could potentially make the battery last longer.
So I usually use CPUSpy to monitor my CPU usage. This comes in handy once the device is rooted and I can see how custom kernels and settings affect battery life and cpu cycles. My LG G4 is the tmobile variant and obviously not currently rooted. I notice through CPUSpy that my cpu speed literally never exceeds 1440mhz.
I don't have any problems with that per say, everything on the device still runs buttery smooth without anything more than the occasional hiccup or lag. I'm curious if anyone else has monitored their CPU speeds and noticed the same thing? I just find it a little interesting.
CPU spy can't even see the A57 cores so there's no way it can see what speed it's running at.
4 cores are limited to 1.44 the rest are 1.8
I have not used CPUSpy. But CPU-Z will show you the speed of each of the 6 cores. As mentioned, the last 2 are the only ones I've seen reach 1.8GHz, the first 4 seem to top out at 1.4 GHz.
Ok.. Using cpu-z..
That's how mine looks "at rest". When it's sitting quietly, saving the battery. Crank up some apps, and you should see those clock speeds rise.
But, trying to improve my battery life, and keep the temps down, I've been hoping to see those numbers stay low, not actually show how high they can go
I agree.. As ive stated, the device runs great i just found it odd. It even calls it a 1.44ghz cpu in the cpu profile and mostly no matter how hard i push the device i cant break that speed
Right as CPU-Z opens, the clock speeds spiked briefly. I was able to get a screenshot quickly.
Do yours also jump up for a second or two right as the app opens?
This has been discussed already. As the previous post shows, they do get to 1.8Ghz when required.
