Only 1G out of 8G showing up?

Postby beastmanh » Tue Jan 22, 2013 9:55 pm

Hello all, thanks in advance for any advice you might have.

I just got an HP ENVY dv7, with an intel corei7 and 8 gigs of ram. I installed 64bit Mint Maya on it and completely wiped out winblows. After noticing it was running a bit sluggish I found that mint is only picking up, less than one gig of ram..

Code: Select all

~ # free -m
             total       used       free     shared    buffers     cached
Mem:           907        801        106          0          2        187
-/+ buffers/cache:        611        295
Swap:         8085        186       7899


I'm hoping that this is just a solved issue that I wasn't able to find anywhere, but so far I haven't had any luck.. The Mem is showing up in the bios just fine, but not in mint. Anyone know why this would be happening?

Thanks a ton in advance!

Let's start with installing the PAE kernel, because I think you have the default one still? The default kernel would be able to see only 4 GiB RAM, and perhaps something is causing it to see even less. The PAE kernel can see up to 64 GiB RAM.

To install it, open a terminal and run the following two commands:

Code: Select all

sudo apt-get update
sudo apt-get install linux-image-686-pae linux-headers-686-pae

Sounds like a good start, but I got an error trying to install the kernel. The update went fine, but it doesn't seem to be finding the kernel..

Code: Select all

sudo apt-get install linux-image-686-pae linux-headers-686-pae
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package linux-headers-686-pae is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Unable to locate package linux-image-686-pae
E: Package 'linux-headers-686-pae' has no installation candidate


Is there a typo or something? Maybe a different repo?

Drats. I think that is for LMDE and I got it mixed up :P Do the following instead, that will work:

Code: Select all

sudo apt-get install linux-image-generic-pae linux-headers-generic-pae

WOOOT! That got it!

Code: Select all

$ free -m
             total       used       free     shared    buffers     cached
Mem:          7944        676       7268          0         43        442
-/+ buffers/cache:        190       7754

Aw yes 8) I still got it. Enjoy the new install, it should run a lot better now :wink:

You might want to consider installing Linux Mint 64-bit in the future, instead of the 32-bit install you did now. Though 64-bit will use some more memory for each task, it will be faster for certain tasks as well (especially mathematical actions on large data sets; like archiving, encrypting, video transcoding, rendering, and so on). 64-bit wouldn't have had this problem either :wink:

I see. You said and thought you installed a 64 bit version but inxi indicates a 32 bit version. i686. You wanted the x64 version. If this is a new install, I'd download the correct 64 bit version and do a clean install now rather than waiting. I think you and your system would be happier.
