Help How much ram does the Indulge really have

C

Android Enthusiast
I find it hard to believe the Indulge has such an odd amount of ram. Running cat /proc/meminfo shows a MemTotal: 301864kB. If you convert that to megabyte its 294.78906 which rounds up to match the 295 shown in task manager.

My issue is that this doesn't seem right. There are no 300mb memory chips available. The closest I know of would be 256+64=320 or perhaps 256+128=384. I know earlier android kernels had an issue addressing over 256mb of ram but the Indulge with 2.2.1 doesnt have this limitation.

Some have speculated that a portion of ram is reserved for the OS. This may be true but how can we uncover this and verify the amount?

Unfortunately any normal application ran in the OS doesnt have hardware access so they will all use the shared function that the task manager is using to show the amount of ram.

I did try to use PS and TOP to figure out the total ram by adding the resident set size but something weird started to happen. Every time I ran either of the tools again the total would increase.

Any ideas?
 
According to online specs, it has 512, but my phone also reports close to 300 mb, which doesnt follow the Power of 2 rule in computing,

If it really does have 512, it could be that some of it is shared for video memory,

thats just an educated guess, dont take it for truth.

Lets research some and find out
 
Some of the online specs say 300 and some say 512. I think they are just guessing to be honest. I want to find a definitive way to prove it.

BTW here is a lovely quote from Samsungs website regarding the Indulge
32GB On Board Memory

Here is the link to the Cricket version which also doesnt mention the amount of ram

"32GB On Board Memory"

LOL, Im pretty sure it has 2gb onboard memory >_<



On the ram topic:

On a terminal emulator, the command

$ free

will show you how much ram you have,

My output came out something like:
Total Used Free Shared Buffers
Mem: 301860 299112 2748 0 7740
Swap: 0 0 0
Total: 301860 299112 2748
 
I thought "free" reads from /proc/meminfo

cat /proc/meminfo

Either way I think they are all inaccurate.

Edit: I found where some of it is reserved by the kernel. 120540kb in fact. We now know the indulge has at least 412.5mb ram. Some info to help you understand can be found here http://forum.xda-developers.com/showthread.php?t=816229
Once we get a kernel to compile I bet I can increase the available ram to 312mb (difference of 18432) with everything still working based on endless reading at XDA

k0nane, have you experimented with tweaking these values? Are the values that you have in Basix identical to what the stock ROM had?

Inquiring minds want to know...
 
Yes a portion is reserved for the OS, they never give you full memory, this is common for example.. if you buy a 16 GB memory it only has 14 GB. If you buy a 8GB Ipod, the ipod really has 6.5 GB.. they never give you the full amount instead they round up.
 
Um, you do realize that your answer has absolutely nothing whatsoever to do with my question, don't you?

And just in case you didn't know it, 1K = 1024 bytes, 1M = 1048576 bytes and 1G = 1073741824 bytes.

Darky's RAM hack has not been implemented in Basix. As for tweaking those values, I have not, because those are known to be optimal for GS-series devices, which the Indulge is highly similar to. In the future I may include the V6 Supercharger which allows users to configure these things.
