RAM....

Not sure if this thread exists, I read threw a few pages and realized there are 105… So, here’s my problem. I have 8GB of RAM, I think… and if not, then it’s 6GB… I noticed in my Kinfo that the OS is only posting 3GB of RAM. Does the OS recognize the rest of the RAM and only post 3GB or is there a RAM limitation. If so is there way to free it up? I’m using 13.1 KDE

First be sure how much RAM you actually have. Check in BIOS maybe

Second is it 32 or 64 bit openSUSE? And which kernel?

If you’re using 32-bit openSUSE without a PAE-enabled kernel, then what
you’re seeing is what you should expect. If you have more than 4 GB of
memory, you need to either run a PAE-enabled kernel or a 64-bit kernel
(the latter is recommended, generally).

It really did not matter how much ram I had, just noticed it was not all allocated. But thank you for the replies. I’m running 64 bit on a DV7. I’m off to check on the PAE… But, before I do is the PAE 32bit or will it affect a 64bit system, because I installed the 64bit openSuSE.

One more thing… I like the way I spelled “through” in my original comment. It’s almost like MicroSoft captured my brain and downgraded me to Win95 with no spell check. Could be 98SE too either or. Not sure which. With only 1 port open for their court amusement. I have the title for the next Windows distro… Windows 9AE… (******* Edition)

In any case… I’m just hoping it’s not Windows ME LMAO. Hope you all have a good laugh and thanks again.

PAE is only for 32 bit it allows addressing above the 32bit limit of 4gig.

Note that Linux uses memory different then Windows. Linux hates to have unallocated memory so fills most of unused memory with caches which it releases as application want more.

Note sure what you ment by “just noticed it was not all allocated” You should see all installed memory in any case

Try opening a konsole and running top i will show you the usage

Ok, run these commands in a terminal:


free -h
cat /etc/os-release
uname -a

and paste it all here, from initial command prompt, to last command
prompt, in a single mouse sweep, and please do so inside code tags (the
‘#’ button in the forum editor).
See photo

It is preferable to see what the commands have to say about things, than
describing them :slight_smile:

What I mean is according to the OS the RAM is not all Distributed or present.

         total       used       free     shared    buffers     cached

There you go

Hi
So that’s only showing 4GB of memory. If you restart the system and select the system BIOS (Press the F10 key), what does it show under system details on the amount of installed RAM?

Ok, but what about the code tags? Please do not forget next time, it is
very important.

You also forgot the “uname -a” command.

64-bit doesn’t require PAE - the Paged Address Extensions allow a 32-bit
kernel to access memory over 4 GB.

If you’re running 64-bit, though, there’s no reason your full amount of
memory shouldn’t be seen, unless the memory sticks are installed
incorrectly (which would be rare in a laptop, but can happen in a
desktop).
