How to find out real amount of RAM + kernel memory addressing issue

[Guest sto1911]

Hello Everyone,

we've been having quite a big debate over how much RAM can be found in the Hungarian version of ZTE Blade.

According to photos and specs on the net the Orange San Francisco has double the RAM than the Blade.

Without disassembling the phone, is there any way to find it out?

df

/dev: 82436K total, 12K used, 82424K available (block size 4096)

/system: 212480K total, 133776K used, 78704K available (block size 4096)

/data: 213120K total, 190948K used, 22172K available (block size 4096)

/persist: 1536K total, 1156K used, 380K available (block size 4096)

/sqlite_stmt_journals: 4096K total, 0K used, 4096K available (block size 4096)

/cache: 42240K total, 3800K used, 38440K available (block size 4096)

Task managers and system infos say there is a total of ~161MB RAM, after a boot ~50 remains usable.

I've also read some rumors(?) that the current .29 version of the kernel is limited to 256 MB of phsyical RAM due to some addressing issues which will be fixed with Android 2.2

What do you think? Higher memory allocation can be enabled somehow (haven't found anything yet) but I'm afraid of bricking the phone...

Install Quandrant and post the system info.

Total 164k kB

Free 6.9k kB

Inactive 65.6k kB

What does inactive mean?

[Guest rayraven]

Ignore the free/inactive.

The total says 424k on the SF, so i'm guessing the Hungarain version does have lower ram.

On a side note, i did hear about the ram addressing issues on android, but i think it's a myth more than anything.

The most ram on android devices is about 512MB now, and i can clearly see more than 300MB free on booting my SF.

The Orange SF has 512 and a .29 kernel.

The Orange SF has 512 and a .29 kernel.

I'm aware of that but as I've read it can be enabled via a kernel option (or something like that).

This NAND chip is the storage I think, is this the same size in the SF version?

Edit:

what are the disadvantages (beside the evident out-of-RAM issue) of having less RAM? Are there any at all?

Unless you are person who uses a ton of apps, 256 should be fine.

[Guest ta3nmi]

I tend to agree that 256 should be just enough, but it is quite disappointing, considering even the users manual for this hungarian Blade mentions 512 RAM, as memory spec.

I'm going to contact ZTE tomorrow, wish me luck for a satisfying answer B)

The answer I got after several emails:

Dear customer,


Thank you for your prompt reply.


Your email has been forwarded to the relevant colleagues for their

appropriate handling.


We will respond as soon as relevant information is available.


Best Regards


Sincerely yours[/codebox]

I will come back if there are any news.

It has 256mb ram, period. I strongly beleive that it has 256mb physically. (there should be one ram IC on these small pcbs, and i doubt they use 512mb for every type.)

Imo you can't hack/unlock it, live with it. Also it's totally irrevelant, unless you're a heavy multi tasker.
