Amount of RAM

Everything I have seen on the internet (including HTC's own specs page) shows the EVO SHift having 512 MB of RAM. However, it seems as if my system only has 368 MB (as detected by V6 Supercharger and a couple hardware info apps I downloaded from the market). Does anybody know why this would be the case? My phone is newer (just got it a little over a month ago). Could HTC have lessened the amount of RAM in the new Shifts?

Also, I am running MikShifted-G v1.6 if that makes any difference.

Mine says I have 367,haha, i believe it might only show total available after all the system android stuff... I am probally wrong because I have AOSP which is so much smaller and less bloated that your sense and i have less.. Haha.. But idk... Just speculation

mine shows,
internal 452/321 free
rom 410/91.9 free

This might help explain things better

Thanks for the link, but I'm just talking about total RAM, not amount free. Everything indicates I have 368 MB of RAM (not internal storage or ROM or anything, but actual RAM). The Evo Shift supposedly has 512 MB, but I know the HTC Merge has 368 MB, so I was wondering if they lowered the RAM on the newer Shifts.
To check the RAM, download the app Android System Info. It is not Internal Memory, but RAM. Mine says Max 368 MB.

My mistake

Has anyone added more ram? Ive seen 1 gig sticks for$38. I might have to try if noone else has. Curious if it might speed the shift up.?

They're talking about internal memory on the phone. Are you talking about an sdcard?

Its possible the gpu has an amount dedicated to it that will not be shown. Sort of like checking the ram on a laptop will show less than the stated specs

[Q] How much RAM available to the user?

Hello, I'm maintaining a thread with values of reserved RAM for many devices. Could someone tell me how many MB of total RAM is reported in the system? Just type free in terminal emulator or use one of the many utilities. I'm looking for total RAM, not just the available one. Thanks

total usable RAM: 512 MB
system regonizeble: 345 MB aprox.
current free usable RAM: depends on your process, usually after reboot and all clear is about 100 - 200 MB aprox.

Thanks, I really hoped around 400 even the N1 had a bit more..
Sent from my Sensation using Tapatalk

Thats because part of the 512mb is used for the gpu. So if 345 is used by system then 167mb is used for the gpu. Thus it looks like its little. But trust me it boosts your graphics intensive stuff.

you must first understand ANDROID's memory management

unused memory is wasted memory

Dual channel ram? What does this actually mean for us

Okay so our phones apparently have dual channel ram honestly. Idk what this means for us Ik we have 512mb does this mean 2 512mb sticks actually adding up to 1gig or does it mean 2 256mb sharing processes also what does it do please any answers would be nice I moved from the sensation and I like this phone it seems faster than it or the evo 3d

Dual channel increases the max bandwidth of memory by using 2 channels instead of one, we probably have 2 256 mb chips, each one with his own channel.
It should help in bandwidth intensive scenarios (gaming for example)

thanks simple and exactly what I wanted

should help but in some cases is useless, it's better to have just one ram unit

Im an ITT graduate for computer forensics. In this age part of my learning was to forensically examine all smartphones as well since they are just as capable in hiding data as computers are. Dual channel means 2 channels of memory as opposed to one to increase bandwidth just as mentioned above. Part of the reason computers are getting faster and gaming smoother is because of increased RAM channels and video cards increasing in GPU Cores and memory lanes or channels, this applies to phones. I actually have one , LG Thrill 4G or AKA Optimus 3D and tested it with a benchmark against some of the newest devices the Galaxy S3 and Galaxy Note 2 both with quad core processors and single channel RAM. My results are as follows:
Optimus 3D: 1856.4 Mbp/s
Galaxy S3: 821.66 Mbp/s
Note 2: 849.39 Mbp/s
As you can see the note and s3 have same memory architecture and practically tested the same the difference was probably in the amount of apps running in background. The LG tested more than double the speed and it only had about 270mb of free RAM at time of test as opposed to the 1300+ mb or 1.3gb or RAM free on note and galaxy. Faster RAM means more responsive gaming and smoother graphics. Now the processor of the thrill 4g is ages behind so its almost unfair to compare app launching and phone reboot to the other devices I have but even the processor difference the RAM tests speak for themselves. Devices in similar time as the Optimus wont even come close to gaming and video playback because the faster the memory the more you can process and more efficiently as well. I'm sure that there is a game or two out there that would run better on the LG than even some of today's phones its just a matter of searching and testing.
I am quite honestly puzzled at why that was the only phone with dual channel RAM, I would have expected today's quad core devices to utilize this architecture and result in much faster smoother running phones with astonishing overclocking results.

Thaaaaaaaaanks for this answer! !!
But I have a question .. in overclocking is that damage the CPU ??? and the same question about the tempreture?? and what the overclocking actually do ?? Why did not lg overclock thier phones ??
Thanks

That is strange because the Exynos 4412 SoC used in the s3/note2 actually supports dual channel DDR2/DDR3 ram with up to 400Mhz clock rate

Agreed after further investigation I realized that the s3/note2 do utilize ddr2 ram...however repetitively running the ram benchmark the lg optimus 3d at minimum doubles the data throughput. ....strange...very strange...

Why does my One S have much less space than advertised

I recently bought a One S and one thing that has really been bugging me is the fact that I have much les storage than advertised. It says that you get 16 GB, but the actual amount is 12.14, and
2.21 of that is internal memory so I only actually have 9.93 to store my media. Why is this? Also it says it should have 1 GB of RAM but task manager says I only have 650 MB.

16 GB storage is partitioned and some RAM is reserved for the system and the GPU.

First off no hdd or flash memory is ever 100% as advertise because its been formatted to run. That's why there is only 12gb instead of 16gb. And that 2gb is the space dedicated to app installs. And the remainder is for you to do with however you please. Music, videos, extra game data (like many of gameloft games where you need to dl an extra 500 MB or so) or whatever you else you want to throw on other then an app install.
When you see an app in market and you download it and install it, it goes directly to that 2gb partition. If you download an app from a third party website it first goes to the 9gb space and once it installs it, it installs on the 2gb and all you need to do is delete the original dl .apk or keep it as a back up.

The above answers covered the answer so no need to reiterate but I just want to opine that you should consider yourself lucky, HTC doesn't rape you like Motorola does. On the Razr and Bionic, they are advertised as 16gb internal but only 8 is accessible to the user. They allot 4gb for apps and 4 for the OS. Bonus for them is obviously expandable memory.

System takes the resources
On many phones the preinstalled software takes a lot of space. I would recommend to install another ROM. I always do that to get rid of the software I don't need.

Ok. Thanks for the help. But what about the RAM? Shouldnt all of it be available?

As already said, some of the RAM is reserved for the system and GPU. For example my HD2 should have 576MB RAM but it only has 411/403 (depends on the ROM/Kernel I guess) because 128MB is for the GPU and the rest is used by the system. I never actually get that much free RAM (I never get more than 200MB free, and that's only on startup; normally I have around 130MB free) but at the same time it's never really been an issue.

Ok. I just though that everything was shown together because I always have 500 MB of RAM used even with all applications closed.

The phone will still reserve some RAM for itself, and that is not the best indicator of RAM that's actually in use.

HTC One S is a gorgeous piece of hardware. To bad they didn't add sd card support...

System software installed on separate partition usually. So removing them will not add more space to the user data.

[Q] About available ram?

Hi! I would really like to buy this tablet but I heard from somewhere that the tegra 3 gpu and cpu needs 500mb of ram so that there would be only a half gig left to system.
So could somebody tell me what the available ram is for real on that tablet and is the amount of ram enough? And also is tf700 really worth the money?
Thanx in advance

You shouldn't judge it on how much ram it has left. RAM can be used to pre cache apps so theres no loading time. Different manufactures tweek the way android handles RAM. A tablet with less available RAM can run faster than one with more available RAM

There's not a lot that you can do to clog up the available RAM on this thing anyways....Even if you had 500MB available, what kind of applications can actually fill up that space?

I don't know how much RAM is being used, they're not available in the US quite yet. I can only guess that the system will use 500MB or less. On my Bionic, I don't have a big problem of not having enough RAM, so I don't expect it on the tablet (especially since the OS on the tablet is much cleaner than on my phone).
Worth the money? That's up to you. It has the best specs on the market right now and has the awesome keyboard dock, so I think it's worth it.

Listen to ian1, he had something important to say.
Also remember that Android has its own way of not only freeing memory used by running and idle processes, but also of managing various kinds of memory - it is not free/used dichotomy, you have to count in shared and buffered memory (you can actually see it in various OSs nowadays). I have about half of Infinity's 1GB RAM available normally (and right now), which is AFAIU free+buffered mainly.

The TF300 has a LOT of ram available on boot up. Almost a full GB I think.

Free ram is NOT a good indicator of how fast/usable your device is. Android is based on Linux, which has a philosophy of free ram is wasted ram. That is, your device will actually be faster if its ram is full. This is why task killers are considered to be so bad on Android. Just let Android manage itself and don't worry about it.

Ok thanks all I think i'm buying the tf300
