free ram?

[c9550927]

Hi,

I just got my box from a forum sponsor so I know its genuine but I've shocked to see the amount of report RAM to be incorrect in my box. See here

Shouldn't the box have 1GB RAM?

The receiver does have 1GB of ram but holds back a portion for system use, you would need to generate a boot log via a serial cable to get a real readout of the ram size.

*PHEW*

Thanks for letting me know what's going on. I have to admit I've never seen this kind of behaviour in my many years of using Linux, even dmesg didnt give a clue this was happening, where I'd expect to see some kind of message telling me.

[Larry-G]

Yeah it happens with all E2 boxes to some degree, and especially now with the inclusion of the XBMC plugin from Vu+.

[c9550927]

Odd no one talks about this issue, or maybe they do and I've never seen it?.

Also makes it more important to get a box with at least 1GB RAM. Can't say I saw this much disappear with my Uno (i know it didn't have 1GB but i mean proportionally speaking).

The odd post pops up now and again, usually you dont loose that much, I can only assume it is down to the XBMC plugin if you have that installed.

All E2 Boxes Reserve About Half For System Overheads... System/Drivers/Frame Buffer/I/O Buffers All Require Reserved Memory... The Memory Total Is Actually What's Left Over After That...

If You Look At Phones/Tablets Storage And Memory, A Similar Thing Occurs... Same As When You Format A Hard Drive, The File System Takes Up A Chunk Before You Even Start Using It...

Hdd are not like that lol... that's the old 1000 vs 10 24 issue. same with android, I'm not talking about file system reserved on the nand for apps etc as with system files. I'm talking about ram. the two are two different things, The total ram should be 1024 MB irrespective of what's running. free ram I'd expect to be less due to running plug in.

You should always have 1024 megabytes total available, and free would be minus anything used. So actually I think something is wrong here!. These boxes do not appear to have 1gb ram as advertised.

I'm talking of RAM, not available space on the flash/NAND.

Apparently the box does partion ram like this. This is not how linux normally works btw. seems I'm not the only one wondering why this is the case (on x86 anyway)
