Yes, I just found out that not only is our A2 a dual core 1GHz phone with 1GB of ram but that the 1GB of ram is also dual channel....what exactly does this mean? Please don't make fun of me, I'm really bumfuzzled by this....:/
Edit: What does bumfuzzled mean? Lmao

Basically it's a way of doubling the RAM's bandwith by interleaving memory reads/writes among pairs of RAM chips.

It uses two 32-bit wide memory dies for a 64-bi wide memory bus. I think it is DDR at 533 Mhz.
It isn't actually interleaving, that is the practice of sending commands to multiple chips on the same channel, as they take some time to respond. For example you can ask chip 1 for data, then ask chip 2 for data, then read from chip 1 and then read from chip 2. As opposed to ask chip 1, wait..., read from chip 1, ask chip 2, wait..., read from chip 2.
I believe there is only one chip/die per channel on these so these phones do not do interleaving.
For Fun:
Desktop PC's use 64-bit wide memory DIMM's, and are two to four channels wide for 128-256-bit memory busses, generally DDR 1333-2133Mhz.
Video cards, for example, have used up to 512-bit wide memory busses in the past (bost ATI and nVidia have done this).
The video card with the fastest memory bus currently is the ATI 7970, which uses a 384-bit wide GDDR5 memory bus with an effective speed of almost 6Ghz! It can transfer over 250GB/sec stock and with mild overclocks can easily do more than 300GB/sec!
So this means our phone can handle about double vs single channel ram?
Love the insight, that helped alot.

It just means the memory is faster.
dual channel RAM... Did it has any significant benefits...?
Speed guys its for faster access to the RAM.

Hello.
A few days ago I bought on eBay a new GooPhone i6.
My question is. Which CPU, how amount RAM and ROM this phone have?
Some programs like CPU-Z, AnTuTu shows different information.
CPU-Z shows CPU as Mediatek MTK6572, but AnTuTu shows Mediatek MTK6589. I don't know also how many cores that CPU have. MTK6572 will have only 2 cores, but phone shows 4 cores. (GooPhone is not available with MTK6589).
Next: RAM. CPU-Z shows 1.87GB, but LMT Launcher (Pie Control) displays 466MB.
Next: ROM: Phone in different place at setting and some apps displays 64GB or 32GB, but physically device has only 4GB.
Finally: Android version of my GooPhone is 4.4.2 Jelly Bean (API 17 - 4.2.2).
How Can I check normally hardware of that phone and how can I fix that mistakes?
Best regards.
Hi,
I got an Alcatel OneTouch Pop C7 with current specification :
Brand Alcatel
Model One Touch Pop C7 7041X
Also known as Alcatel Pop C7 7041X, Alcatel OneTouch Pop C7 OT-7041X
Operating System Android 4.2.2 Jelly Bean
CPU / Processor MediaTek MT6582M / ARM Cortex-A7
Processor Clock / Cores 1300Mhz 32bits Quad-Core
RAM Memory 1GB LPDDR2
GPU Graphical Controller ARM Mali-400 MP2
Internal Storage 4GB (2GB user available)
External Storage Until 32GB microSD, microSDHC
The phone works great but for unknown reasons the battery don't charge.
I even changed the battery and the Charge jack but still the battery don`t get charged ...
Curiously, the phone shows that the battery is charging
Any ideea on fixing this...could this be an software or hardware issue?
Thank you for your assistance.
update
I used SP Flash tool and upgrated the phone to kitkat 4.4.2 and i putted to be charged...
1th test with phone running..
The battery have 2% at that time...and after 12h the battery was 47%. Normaly its charged in 3-4h
2th test with phone shutdown..
After 2h on charging battery stayed at 10%...but the phone shows that is charging..
My conclusion is that the the phone have some hardware problem...

I am looking to buy a tablet I come across 2 tablets which have intrigued me the xperia z3 compact and the nvidia shield k1. I liked them both for the specs and low price. The tablet will be used for surfing the internet, youtube, Facebook, games, watching movies things like that so I was wondering if someone who has both or has had experience can recommend me which one is better or if there is another tablet that is better suited for me.

If they both are the same price which one would you go for?

I bought the Shield yesterday because I want to play games with.
But If I was not in this situation (more video/internet/app usage) I will definitively go for the Sony because despite the smaller battery she has better battery life and not a little it's like 10 hrs more in certain condition so very well optimized rom from sony.
But maybe I can fix the shield battery with a custom rom will see
The z3's bottleneck is the GPU.

If you set the Shield power mode to just 2 CPU cores, you'll get much more battery life.

And the shields interface remain smooth?
No problem for watching video and stuff or it start lagging?
It still runs smooth. You may sense a difference with highly demanding games. Or when you transcode videos.

thanks you for all this information
You cannot disable cores on the k1. You can verify this with cpuz. Also the z3 compact tablet has a terrible processor combo by today's standards and doesn't come anywhere near the k1. It also does not have nvidia specific games, console mode, or gamestream (although this can be done with a 3rd party app call moonlight streaming). The speakers are also not as good and it will probably never get another update, ever. There is no reason to buy the sony tablet over the shield.

Then cpuz is apparently showing wrong data, I'd say.
Plenty apps have compatibility issues with a myriad of Android devices.

Unfortunately cpuz is accurate and you cannot disable any cores on the shield tablet, despite what the UI might be telling you.
Benchmarks tell a different story.

Ill run antutu for you right now, 2 and then 4 cores, and post the results. I assure you the cores will all be active no matter what. They are always firing no matter what you do.
The benchmarks do indicate that there is a performance hit, surprisingly. I ran a total of 8 benchmarks to be sure. I am not sure exactly what is happening, but the cores are not being turned off, that's for sure. You can verify this with any CPU monitoring app, I tried 5 different ones and they all said the same thing. I think maybe when you force the CPU into 2 core mode, it may under clock two of the cores or something, but not disable them. It's helpful to know that the option at least does something and is not just there and fake lol. However like I mentioned in another post of mine, setting the performance mode to custom to enable only two cores, will perform worse for battery like than just using optimized. Forcing two cores for individual games, might be helpful however, but probably not by much. As you can see from the following benchmarks, the scores are not halved by disabling half the cores, they are only slightly reduced. Not exactly sure what's going on, but may look into it further in the near future.
Benchmark 1 - two cores enabled:
CPU: 18378
Benchmark 2 - two cores enabled:
CPU: 18374
Benchmark 3 - four cores enabled:
CPU: 22660
Benchmark 4 - four cores enabled:
CPU: 22409

Under what kind of conditions would that be? Engadget's review says 13.5 to 14 hours for their continuous video loop test, and they estimate 10 hours in "real world" use conditions.
https://www.engadget.com/2015/01/11/sony-xperia-z3-tablet-compact-review/
I get around 7 hours of screen-on time with my Shield, running stock and not messing with the cores.
The Sony tablet's battery life is impressive, for sure. But to say a 10 hour difference, is probably an overstatement.
This thread makes me wonder (yet again) where are the tablets? I know the tablet market is pretty stagnant, but its still a bit ridiculous that we are sitting here comparing a tablet from 2015 versus one from 2014. NVIDIA shelved its plan to update the Shield tablet this year. Not much else on the market. On the higher end, Samsung neglected to update its Galaxy Tab S2 this year.

maybe not deactivate but consume less battery it's what I need

So under what circumstances will you switch to 2 core mode to save battery? The tablet has great battery until it fires up a game and there's not much you're going to do about gaming battery life.

more battery for movie/netflix

Switching over to 2 cores during a movie will likely cost you battery due to the fact that the minimum clock speed for custom is much higher than the minimum clock speed for optimized.
