[Q] why some atrix 2 ics are at 1Ghz and some are at 1.2Ghz at ics update?

[pritkudale]

as i heard the some atrix 2 are updated to ics with 1.2Ghz with ota update. But some device are remain on 1Ghz. Whats the reason? and how to get 1.2Ghz while updating.

I guess it sheer luck. some have better silicon in them.. .
Most likely that it checks whether your device can handle 1.2 ghz, If it can, then very well. If not, then it sticks to 1 ghz.

This has been covered many, many times now. Please search, as there was no need to open a new thread!

Is it possible to get 1.2gz by sbf rsd lite flash without rooting

I don't get you? you mean to say, is it possible to flash OC zips without rooting?? then no.

 

[pritkudale]

by simple stock update

Flashing with stock sbf without oc zips. As someone people are getting 1.2gz while updating. There defiantly some script in stock rom which is selecting to bump processes to 1.2gz or not.

There are many things determining a CPU speed and GHz is one of them. Other things include the number of cores, the number of threads, the speed, latency, size and bandwidth of the cache and memory controllers, the accuracy of the branch predictor and the number of instructions executed per clock cycle.

But these are just technical features. You can never look at a list of specifications on a CPU and accurately guess its performance, because its performance depends on too many things. (You can, however, use GHz as a rough indicator of relative speed between two processors that are essentially the same (or similar) in all other respects.)

That said, all Atrix 2 CPU processors are created equal, but they may not perform on an equal level. Think about this, CPU processors are manufactured to perform at higher clock speeds than those in which they are set by the manufacturer. This is a fail safe built in to the micro architecture of the processors to prevent damage to the processor and/or other components.

Imagine if you will, your Atrix 2's CPU processor has 1,000 tiny dots of silicone. Assuming it can withstand the highest workload demand from the silicone, it will run about 90% of that (due to bad or sub par silicone), but in order to prevent damages as aforementioned, the manufacturer will only allow for about 60% of that silicone to run at its stock CPU clock speed setting.

So, since the (imaginary) 1,000 dots can fail over time, or at the time of manufacturing, clock speed ls are set much lower than they might theoretically be apt to handle. Now, why do some Atrix 2 CPUs run higher after an OTA? Could be those processors had more functionality in the silicone to handle that higher speed. A updated system version changes everything - system wide. If, during an upgrade, the system determines the CPU workload capable of doing more 'work', it might allow for this. Otherwise, well, it won't.

Again, these last few paragraphs are hypothetical, but something to consider.

Also, a simple search in the forum would have shed light on this as well. All you have to do is dig a little...

Are you absolutely certain of this? I have been reading about this for the better part of the afternoon, and threads like this one:

http://forum.xda-developers.com/showthread.php?t=1988411

...seem to categorically state that there are two distinctly different and unique processor chips used in different Atrix2's, with different numbers of factory min/max steps for clock speed, and which one you end up with is sheer luck of the draw based on manufacturing batch, date etc.

It says that depending on which chip your device has, you'll be able to overclock to different maximum levels safely. Is that thread just completely wrong?

I'm from Argentina and I flashed the European version of ics (not att), now I have 1.2 ghz ... maybe depends on the phone model (ATT or international)
