Adding More Ram Via Sd Card
 

Is there a way to add more ram through the onboard sd card. I think this phone is great other than the limited amount of ram. If we could up the ram say to 512 or even 1 gig i think it would take care of alot of lag issues we have with tf3d. I know in win7, if i insert an sd card it will ask me if i want to add the Sd memory to speed up the system. So is it just a programing issue thats stopping us from doing this or is it a hardware issue?

not possible

Re: Adding More Ram Via Sd Card
 

you care to share why it is not possible?

It would be pretty cool if we were able to that. Sort of like like the VISTA/7 feature READYBOOST.

exactly i don`t see why it is not possible. Maybe we could get a dev to check it out i would be will to pay 20 bucks for it.

With what your talking about is absolutly physically impossible. Our phones dont have the hardware capabilities to reallocate the unused RAM in the SD cards to allocate them to be used as accessable RAM in our phones, thus making it impossible. Its all hardware bud, sorry.

Well, it is feasible to have a portion of memory of SD card as Virtual Memory just as Windows platform (physical memory and virtual memory). So it is possible but probably only Microsoft can do it.

anything is possible... but until msoft comes out with it... its impossible!!! lol so both parties r right... our phone doesnt havent have enuff cache to use sd card as a readyboost.

On the hardware side, it cannot be done because the processor is not designed to do this. The processor knows where it's memory location is and that is all it will use. As for virtual memory, I've never thought about this for a phone but I don't see anyone coding this for windows mobile. Is there really a need? The device you buy is designed to operate a specific OS and it does it well (most of them anyway). It's not until you start tinkering with things that you run into mem issues. Besides that, looking at the stats on the new hardware available for the mobile platform in the next year, I don't see us having many issues with lag anymore. 1.5 dual core processors, separate GPU's and devices showing 1+ gigs of RAM. I think overall that we will be okay without virtual memory.

EDIT: Also, people would really screw up their phone when they pop their SD card out before powering down the device or using Disk Drive mode when connecting to PC.

Kind of like it wasn't possible for decades through all the previous versions of Windows until Vista came out. Alot of reasons.

True and also the processors on our phones dont support cross-over memory allocation to even allow memory virtualization, which no phones support that memory feature. Heres what im talking about. This is what our phones need on a larger scale to be able to reallocate the physical memory from our SD cards to our RAM scale. :)

Re: Adding More Ram Via Sd Card
 

What? Windows 3.1 used Virtual Memory. It used the HDD not an SD card but it's still virtual memory.

Re: Adding More Ram Via Sd Card
 

Thats true as well. But what he probably means is the fact that now the user can limit the ammount of memory you want to "pull" from the removable device.

Re: Adding More Ram Via Sd Card
 

Too many big words in that thread, I glanced at it and got a headache. I only have a minor understanding of programming and how the information is sent to the processor which in return allocates X space of RAM to hold the information until it is called by the program. But even with my basic knowledge I can safely say it is not possible to allocate space on the SD card as system memory on the hardware side. Are you saying that it is also not possible to do so software side?

Re: Adding More Ram Via Sd Card
 

LOL. Sorry man. Ill simplify it in a diagram:

INPUT ---> KERNEL DEBUGGER ---> CODE > BINARY > DATA ---> PROCESSOR ---> RAM=CACHE ---> OUTPUT

Thats how the basic computing works. And say you have a 2.3GHz CPU speed, it will do all of that at 2.3GHz. Plus, when you pull free unallocated memory from a different source, it pages into the RAM cache bin. Sorry if thats to confusing, but thats about the most simple way I can put memory virtualization on mobile phones.

And no, even with software, its utterly impossible. Theres litterally no way of getting around it. I can guarentee that the new Snapdragon 1.0GHz mobile CPU's will support better memory virtualization. If you have any more questions about hardware or software, feel free to ask. I am A+ cert. :)

No that's not confusing at all. You dumbed it down just the right amount. Thanks, makes sense now.

Excellent. :) And thank you too.
