 Posted: Sat Jan 12, 2008 8:38 pm Post subject: Possible memory problem.. (more like user problem) [SOLVED] |
 |
|
Hello everyone. My name is Sal. I am a fairly new user (about four months now) to Gentoo. I recently decided to switch to a source-based distro from Slackware. I love it and I'll never go back (sorry Patrick). I have one slight problem on my machine, though. I have a Toshiba Satellite A75 (2.80GHz P4 w/HT, 512MB DDR PC2700 SDRAM, 60GB hdd, ATI Radeon Mobility 9100). I know for a fact that this system has a built-in 512 MB memory module, yet when I run 'free' I get the following result:
| Code: | $ free
total used free shared buffers cached
Mem: 383536 217416 166120 0 16712 101344
-/+ buffers/cache: 99360 284176
Swap: 763076 212 762864 |
Here is the output from lshw:
| Code: | *-memory
description: System Memory
physical id: 16
slot: System board or motherboard
size: 512MB
capacity: 1GB
*-bank:0
description: SODIMM DDR Synchronous 166 MHz (6.0 ns) [empty]
physical id: 0
slot: JP21
clock: 166MHz (6.0ns)
*-bank:1
description: SODIMM DDR Synchronous 166 MHz (6.0 ns) [empty]
physical id: 1
slot: JP21
clock: 166MHz (6.0ns)
*-bank:2
description: SODIMM DDR Synchronous 166 MHz (6.0 ns)
physical id: 2
slot: JP21
size: 512MB
width: 64 bits
clock: 166MHz (6.0ns)
*-bank:3
description: SODIMM DDR Synchronous 166 MHz (6.0 ns) [empty]
physical id: 3
slot: JP20
clock: 166MHz (6.0ns) |
The BIOS, and lshw alike, recognize it as 512MB...
Any ideas what I might have messed up? I've already had too many people tell me it's a HIGHMEM issue before they even found out how much RAM I have. How could it be HIGHMEM if it's less than 1GB? As far as I know it cannot, but please correct me if I'm wrong. Thank you in advance for any input.

fire in the livecd and run memtest... does it report 512? (let it run for a few loops) does it report any errors?
cheers

| How much memory is being used by the ATI Radeon Mobility 9100. You can also check the output of the dmesg command for memory allocation. |

Well, actually.. I made an error. The BIOS also incorrectly reports "383M System RAM," however, when running through memtest86 (which also reports 383MB), there was not a single error in all of the (tested) RAM.

Well, I thought that could have been the problem as well, but take a look at the 'dmesg' output I got:
| Code: | Memory: 378700k/392640k available (3623k kernel code, 13380k reserved, 293k data, 2024k init, 0k highmem)
virtual kernel memory layout:
fixmap : 0xfffb5000 - 0xfffff000 ( 296 kB)
vmalloc : 0xd8800000 - 0xfffb3000 ( 631 MB)
lowmem : 0xc0000000 - 0xd7f70000 ( 383 MB)
.init : 0xc0206000 - 0xc0400000 (2024 kB)
.data : 0xc0831000 - 0xc087a5c0 ( 293 kB)
.text : 0xc0400000 - 0xc0789ffa (3623 kB) |
What do you think? Thanks again..

yeah, now that i do the math, your video card doesn't have its own memory and is using 128mb of system memory... that's why its not counted.
cheers
edit: the option should be changeable in the bios.

Yeah I just found out the same thing when I did a google search. I am really sorry guys I was under the impression my video card had its own memory (apparently most of the mobility ones don't?).. I'm going to buy a 1GB PC2700 DDR stick within the next few weeks and fill this machine to the max capacity... Thanks a lot for the help guys.

check with your laptop manufacturer to see if that memory will work in your laptop... some have limits as to how big of a stick you can install.
cheers

I already checked it. The max it will support is 1GB (in addition to the built-in 512MB) PC2700. Thanks again.
