Maximum temperature for the Vibrant's hummingbird CPU? - Vibrant Q&A, Help & Troubleshooting

Just wondering if anyone has a verifiable link or info about what the 1ghz hummingbird processor is rated to as far as temperature is concerned? I don't want to overheat my processor and hurt my phone in the long run by OC. Thanks!

Hello..anyone can teach me how to overclock xperia x10
Bootloader is not unlocked. It's impossible at the moment.

First, you crack the bootloader.
When you've done that, I'm guessing you allready figured out how to OC the CPU

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".

Curious about our gpu

im curious if its possible to somehow manage the power consumption of our phones during heavy gpu usage. when i watch youtube or play games it drains super quick. i was just wondering if there was a way to make it work more efficiently with our processor or is the processor clocking what defines the gpu power consumption?

The Qualcomm MSM8655 is what's known as a SoC, system on chip. The GPU is on the die. Whatever demands are made on the GPU are effectively made to the whole chip. If you're looking to reduce the power it uses, you need to being down the top clock rate.

CM7 Cpu Settings

I flashed the cm7 1.4 240-325-300 Kernel.
In my settings what should I keep my min and max at for all time usage?
I max them and my quad score is like 5501
don't know if your supposed to keep those certain.
Also does decrease or increase battery life.
I left mine at the default values. Was wondering this myself though. How do you test quad scores?

You want the lowest value to be at the lowest(216 i think) because this allows the processor to idle at that low speed, if you keep the minimum speed at 1ghz your processor will ALWAYS be running 1ghz at the lowest, and that will be an obvious way to kill your battery in no time. So set that to the lowest, and for the maximum i personally run mine at 750 for CM9, think i had it at 800 for CM7 but cannot remember for sure. This is limiting how fast the processor can run so the lower the better as far as battery goes. It comes down to you personally, if you game and do processor heavy tasks often then having the processor underclocked like i run mine will affect your gaming/app/overall experience. Its always like 2 clicks away to bump it up to a higher speed and i have a link on my home screen so if i do decide to do anything processor heavy i can bump it up quickly. But in general it takes more power for your processor to run higher so if your really concerned about battery life try bringing it down. I can still score a solid 1,500+(with a bunch of crap installed on my Photon mind you) on CM9 with my max at 750 and min and 216. Benchmarks are honestly just a number, it comes down to how if performs for you and what you are doing with your phone.
Awesome, I'm lowering it now and battery is dropping slow so its good, thanks for the detailed reply.

[Q] Has anyone actually burned out a cpu from overclocking

Are there any reports from anyone out there that actually killed their phone/fried their cpu from overclocking. I would search...but it's not working
I don't know about the CPUs used in cellphones, but how many burned out CPUs would you like? (I know someone who uses them as parts of his grunge art, and he actually buys them from computer repair shops for about a buck a piece to make sure he has enough.) It's not as common these days, but back when the "art" was in its infancy people burned them out all the time. And when vendors stole the AMD fans and substituted cheaper ones - back in P2 days, IIRC - there were more burned out AMD chips than working ones. (Normal clock on an undercooled chip is the same as overclocking a properly cooled chip.)
So yes, it can probably burn out the CPU unless you keep the overclocking to a minimum, which won't buy you anything noticeable in performance. I laugh when I see people posting that they're overclocking a 3.2GHz CPU to 3.3GHz. If that saves them 2 seconds a year they're lucky.
Well never heard of anybody burning there smartphones CPU, but there are a few app like SetCPU, where u can set profiles for when the temp of ur processor is to high to downclock it.
Also i have heard of people overclocking there phones to twice there normal power and never had any issues.
Theres no need to literally burn the cpu, but you can easily shorten the life of the phone
If you have control of the voltage, and can take it beyond the CPU's limits, it should be quite easy to burn out your CPU.
With that said though, most apps and kernels have safe limits in-place on the voltage and clocks you can set. For example, I can't pass 1.4Ghz with 1500mv (if that's the right term) on my Galaxy Tab. With that voltage anyway, anything above 1.4Ghz is unstable

Very true. I know we are on the subject of phones, but most of today's computer motherboards have that 'safety' feature where if you overclock or the processor gets too hot, then it will shut down the computer. I am sure phones have the same similar feature.

[Q] OC vs non OC

what's the differnce btw. OC vs non OC ? thanks
http://bit.ly/N53rQc
Overclocking is to increase your processors clock speed. The processor comes with a fixed clock speed which is mentioned in it's specs (1 GHz, 1.5GHz etc). OCing is to increase this speed past the fixed or 'stock' value to achieve better performance from the phone. Generally, if a phone has a fast enough processor out of the box, you won't notice much of a difference OCing. The main performance gain will be seen in benchmark tests. But if you have a slow processor, it'll make a difference to usability. Since more processing power = more electrical power, it causes greater battery drain and also reduces the life of the processor in the long run, because it heats up more and there's no cooling apparatus in a phone unlike a computer. A little OCing is fine, but overdoing it continuously will damage your processor. My phone is rated for 1 GHz but OCed to 1.15 GHz. It can go uptown 2 GHz max, but like I said, not good. OCing depends on the kernel of the phone. Stock kernels do not support it, but almost every custom kernel supports it. A non OCed device is one which is running at the stock frequency designated for it.

with OC, ur processor xtra hard working. ur hh rapidly heat, battery drain faster...
so don't do it if u only using hh for simple app (except u want play HD's Games)
sorry for my bad english...
