[Q] How much will an iPhone 4/4S logic board can cost? - General Questions and Answers

Hello,
i was wondering, how much an iPhone 4/4S logic board comprehensive of CPU, RAM, ROM and mass memory can cost?
No need to consider the cost of the camera, display, cover, etc. Also if you can change or access/remove the mass memory (with mass memory i mean the storage, 8 GB or 16 GB or 32 GB and so on) in the logic board, no need to consider mass memory cost.
Also, i already found the original iPhone's logic board for sale; but are they comprehensive of CPU, RAM, ROM and so on? I can't really understand. Looking at the price i wouldn't say that.
Thanks in advance for your time.

[Q] Is there a way to increase RAM?

Can we increase RAM by repartitioning the internal storage? Or is the RAM somewhere else physically?
ram is by itself somewhere separate from the internal memory
ram on the g2x is somethign liek 233mhz i think? someone correct me? but thats hell of alot faster than 5-15mb/sec xD the internal memory isnt that fast... imagine how slow 20-50MB would run form the internal memory if the rom got loaded on there?
mhz would be the speed of the ram, I think the OP wants to increase the ram somehow which I have not yet heard of, that would be in MB
Yes, but he explained well how it would not be practical to use internal storage as ram (even if this were possible) because of the drastic speed difference between the technology...it wouldn't function properly.
No, it is not possible to increase the amount of RAM without physically taking apart the phone and welding some new memory onto the motherboard, which is a horrible, horrible idea and should never be done. Ever.
However, you can free a little bit up by installing a custom kernel, the Trinity one by morfic allows 405 mb to be used by applications as opposed to 374 stock.
its possible if you have some rework equipment or are very good at soldering but you would need to find ram that has the same size shape and pin out at what you had thats a challange most chips in small devices use whats called BGA or Ball Grid array its makes it so the pins of the chip are under it so it saves space. but it makes it all but impossible to resolder another chip on there.

I would have to agree with ikoolkid but if u really want to know then:
1. Make sure your motherboard supports the processor you're trying to install (socket type, bus frequency and size),
2. Since you're trying to implement ddr3 ram, make sure the motherboard supports it, otherwise, don't waste your money buying ddr3 ram modules.
3. For graphics card, make sure your motherboard supports it.
4. make sure your power supply has the capacity of giving power to all components, add the power requirements of all devices and that should be a guide of how big u want that power supply.
5. read the specs for the motherboard and you'll find out if all those parts are compatible.

Just at a glance, I'd examine the case and PSU.
You want a case with good ventilation, and for that price, I doubt that's a great case - but pictures would help. You want one with cable management space too.
And your PSU will likely not support a decent GPU.
Not to be a jerk - but I built my first computer recently and unless this post is weird spam, I recommend you do research until you understand what you're doing.

I've done some research on the compability of CPU, MB and RAM and they seems to be compatible, it has (by the asrock site specs)
- 1 x PCI Express 2.0 x16 slot (PCIE1 @ x16 mode)
- 1 x PCI Express 2.0 x1 slot
- 1 x PCI slot
for a new graphic card, but in my opinion, looking at the card, put a nice 2 slot graphic card would be a problem because of the space.
For the HD its ok, the MB has 6 SATA ports so fully compatible. As Pennycake said, the PSU should be more powerfull if u need a decent graphic card, otherwise for the combination u wrote it would be perfect.
Like others have pointed out this is not the place for this post we are a mobile device developers forum not a computer help website, please use the off topic area
It is compatible
Although of the off topic area might be better suited to this, I'll answer it anyway. So the main components that you need to worry about, the CPU and the motherboard, are both compatible. Be careful though, I have AMD processors can be quite easy to burn out if the processor isn't inserted correctly. Everything else should be fine. Don't be too concerned about heat with that case, you are powering a dedicated graphics card and by the time you do I don't think you will be aiming for a demanding high end one anyway. Cheap power supplies can be issue, so you be wary of any sudden shut downs, as it could be that in the future. Other than that good luck with your first PC build. Every one after this will be a breeze.
Oh before I forget, make sure that you have Sata cables for the hard drive, they usually come with the motherboard, but that isn't always the case.
i recommnd u 2buy cheaper ones,..

Cheaper what? I am not sure they could go much cheaper.
Yea make sure the motherboard socket size matches the cup, everything else is pretty cross compatible. You don't want to order the wrong cpu and be like aw grits I ordered the wrong part and wait another week.
The cpu and the motherboards socket definitely marry up, so that isn't an issue. Like I said though, be very careful with installing AMD cpus.

[Q] Android tablet specs????

Hello,
I have a tablet GOClever TAB T75 and I have a strange caracteristics and specifications about it.
Android OS 4.0.3/4GB flash memory/512MB RAM
Hardware is:
Memory: 29F32G08CBACA [Micron Technology - MT] - 1pc on motherboard
RAM: HYNIX H5TQ2G83CFR - 2 pcs on motherboard
Correct me if I am wrong.
Flash memory some internet pages reports that is 4GB some 8GB.
For RAM I go straight to manufactor web site it's 2GB DDR3 ram module and tablet motherboard have 2pcs.
So my question is why Android OS showing only 4GB Flash memory (I think this is ROM - correct me if I am wrong) and 368MB ram (usable) and 512MB (total RAM) where on motherboard are 2pcs of HYNIX memory 4GB RAM?
Any advice and explanation?
Thank you
anyone????
Well what is your question?
If u got the tablet sold to you as a 4 GB. That is the whole system and storage total. Usually partitioned into 3 or 4 partitions.
Not really sure what u are asking, them Chinese tablets are made by about 100 different companies. Ram isn't removable if that is what your thinking

I'm kind of confused.
The tablet is 4Gb of internal storage and 512Mb of RAM. There's really nothing more to be said. Android is only showing that because that's what is there. If you got scammed that's another issue - but if it was sold to you as 4Gb flash memory and 512Mb RAM then that is what you do have.
Like ronedogg said, the 4Gb is all the internal memory, including space for your ROM (software that makes the tablet run). That's all there is to report because that's all there is.
The RAM might be "2 pieces" of 254Mb RAM. It's not 2Gb - even if you have a copy of a tablet that's supposed to have 2Gb RAM you do not have that, you have 512Mb RAM. Nobody is putting 2 pieces of 4Gb RAM in Android tablets - you only see that in Windows tablets that have Intel processors and tend to be very expensive. Did you pay over $1000USD for this tablet ? I hope not. :silly:
Your RAM is probably 2 modules of 254Mb RAM, if it's even "2 pieces" at all. Generally when reporting RAM they will tell you total RAM, not some number that you multiply, anyway.
Hello,
Thank you for informations. I payed less then 80USD for tablet (used - not new).
Even that tablet have 512MB ram when it's on Android shown Total Mem.: 368,36MB ram (used for OS around 150MB) so Free ram that I can use is only around 200MB (on stock rom).
So that's I am confused why have 512MB of ram and usable only 200MB. Or it's just SW blocked???
In attachment are specs for module.
Thank you
BR
Well, what is the Ram that is being used going toward? The system can take more than 150Mb from what I've read.
I don't know what you have specs for, but I'd be willing to bet my firstborn that it's not what is in your device. You could open the tablet up to confirm it yourself, but if it was sold as 512 and reports 512, why do you think it would be otherwise?

8GB or 16GB - Does it really matter?

There seems to be some good deals around on the 8GB model at the moment but not for the 16GB. Obviously more memory is always better - the phone it will replace is the Samsung S2 which has been memory bound, however with an SD slot in the Moto G will it actually be an issue having less onboard?
I know that Android M has ability to use SD cards for system storage and that it hasn't been released yet. This can only be a few weeks away?
At near half the price of the 16GB, is the 8GB a much better purchase?
What about the difference in RAM? 2gb better than 1.

Oh, I hadn't appreciated that - thanks for pointing that out....I guess it could be a bit of a dog without enough RAM?

My 1GB RAM model is pretty great for the price. Battery life is fantastic, however having the low_ram flag enabled in build.prop is a bit of an issue for some apps.

1 GB RAM vs. 2 GB RAM really does make a difference.
Initially I bought the 1 GB Moto G, as here in Germany the 2 GB version is only available with a hefty price tag via Moto Maker. Later on replaced this with a 2 GB Moto G ordered from Amazon Italy (less expensive than the 1 GB version here in Germany ).
At first glance performance is pretty much the same.
Though the 2 GB version can keep more apps in memory in the background.
With 1 GB I had sometimes the problem that Android did kill e.g. the Music player running in the background while surfing the web with Google Chrome (Chrome is a huge memory hog).
So far I didn't have such issues with the 2 GB Moto G.
Also the 2 GB version is for sure more future proof. Which is important if you are not willing to buy a new phone every 1-2 years.
My previous phone was a Samsung Galaxy S Plus. Which was perfectly ok for my everyday tasks since I think back in 2011 until a few weeks ago - thanks to good custom ROM support.
What made me exchange it for the Moto G in the end was the performance bottle neck caused by the lack of free memory (512 MB) and not the CPU or the rest of the hardware.
So I hope thanks to 2 GB RAM the Moto G will last me at least as long as my old Galaxy S Plus.
It doesn't really matter if you picked up a high speed SD card and use Marshmallow. I've seen no problems with the external SD -> internal SD feature.
About the RAM difference, you should use virtualized RAM as soon as you can if you're using the 1 GB model.
I only paid the extra because of that extra 1gb of ram. Believe me...it matters!! If you want to keep app updates coming, xposed modules running, etc etc....you need that extra ram. This is a great phone out of the box, but if you're here and you're asking, you're probably not leaving it untouched
I've got the 1gb model, and never found myself wanting more. Of course I keep my use simple. But for what I do, its more than enough.
My previous device had 1 GB of RAM. In my opinion, the 2 GB is definitely worth the extra cash. The multitasking difference is night and day to me, and I no longer have to worry about what is running in the background slowing the device down. I do a fair amount of gaming on Android as well, it is nice to sit back and play a game with Pandora or similar running without the OS killing it to free up memory for the game.
The 2gb makes it much more future proof. I have the 2gb version and I have never had to close any app most of the time. With 1gb of ram, you will have to close apps much more often making multi tasking a little more difficult.

What is 'virtualized ram?'
I'm in the boat with the 1 giggers and I'm curious how to do that.
I mainly use this phone for office tasks and it performs incredibly, but hey! An increase is an increase right?
Also curious about the posters response about low_ram flag.

In Kernel Adiutor there is a Virtual Memory section and if you scroll down all the way there is a slider called Z-RAM. You can adjust the size of the memory there. Instead of using a swap file this compresses the RAM, making room for extra storage. But it has downsides, the extra processing required to compress the RAM eats the battery at a slightly faster rate.
I haven't heard about the low_ram flag, I'm afraid that I cannot tell you about it.

Thanks! It passed me honestly because I haven't messed around with any kernels since my n5. Usually just flash and let it fly lol I'm gonna check it out now though, appreciate the push!

6gb vs 8gb for better battery life (based on op5t experience)?

I was wondering for light to moderate use which model between the 6gb and 8gb do you think would be more taxing on battery.
I'm assuming I would likely never fill 6gb as I close apps when not in use and only use a handful anyway.
What are your thoughts?
I'm no developer but if I had to guess, I don't think the difference in RAM has any effect on battery life. If it does, I'm sure it's so little it would be impossible to notice. Anyone who is more knowledgeable than me on this, feel free to correct me if I'm wrong!

Good question ! I was also wondering the same thing. Logically speaking there should be a difference but only significant if there are less physical chips on board for the 6GB model. I am very much inclined to order the 6GB model for a bit better battery life - 64GB of storage is plenty for me anyway.

Thing is, just like with flash storage, the controller and actual configuration of the chips will make power consumption vary wildly. We don't know the clock speed of the LPDDR4X RAM they are using, maybe it's different between the 6 and 8gb version.
Same as with the NAND chips, many factors have an influence on the electrical consumption and maybe they tweaked the 128 and 256gb version to be more energy conservative at the cost of speed.... speed that may be regained due to the fact that NAND arrays/strings are faster when there are more cells in them.
Then there's the use-case... IF the 8GB version has worse energy consumption values, maybe it still has better battery life because it can store more apps in RAM and has less need to constantly access the flash memory ?
TL;DR : we can make hypothesis but in the end there's just too much we don't know to really say if one is more energy efficient than the other.
more goods is better always !!
now with 8gb ram I can open all my apps and keeps them opened all day which will stress less processor power and keep battery.
Also, I need as much as possible storage, 256gb is ok for now.
We don't know how to get fine the kernel and OS for more ram, I would hope they would reduce compression so it strains the CPU less i.e. zram, or use the extra space to cache more things across the OS to keep things more consistent. I don't notice anymore apps open on the 8gb op6 Vs 6gb op5t.
In saying that my op6 has yet to use more than 5gb ram
ram uses the same power regardless
if the chip is the same - both use the same amount of power
only difference will be one can have more apps in memory than the other (assuming you can fill 6GB of ram... on a phone...)
other than that zero difference
Considering how experiences on the battery related threads seem to vary wildly, I wonder if this is the cause?
I was considering downgrading from an 8Gb version to 6Gb, but if I plan to keep this phone for a few years is it better to hold on to the 8Gb?
3Gb seemed like overkill when I first got my OPO but now it is less than some budget phones provide.
My OP6 - 6Gb close Google Maps and Sportify with 2,1 GB free...

Nothing to do with battery life, but there seems to be some very aggressive ram management on the OP6 which affects the 6Gb version much more than the 8Gb: https://youtu.be/t5UEN2vpchQ
Maybe I will keep the 8Gb version after all.
