Hello,
last week, when booting a virtual machine, I discovered that my
laptop only recognizes one of the RAM modules (supposed to be 1 GB,
but truly providing 880 MB). I realized this when VirtualBox
complained that I had configured more than the available RAM to the
virtual machine. I had not changed the virtual machine
configuration, and the virtual machine had about 950 MB assigned (and
my physical host, only had 880 MB).
Since I previously had 2 GB of RAM, I assumed one of the chips was
broken somehow. I replaced one of them, and I still got this output
for the "free" command:
$ free
total used free shared
buffers cached
Mem: 902264 892608 9656 0 23624
621432
So I put the original module back on, and changed the other one. I
entered the BIOS, and it detected 2048 MB of RAM. I run a test on
the memory (from the BIOS), and everything seemed allright. But my
Debian keeps seeing only 902264 of RAM.
I downloaded a new Kernel, re-compiled, but everything is still the
same. I am running Debian Sid, if that could matter, but I can't see
how that would affect the amount of RAM available.
Running lshw, I get the following ouput:
*-memory

Could the difference between the clocks available on the RAM chips
only allow for one of them to be used?
Thank you in advance,
Best Regards,

Please post the output of your dmesg.
Is your on-board graphics card utilizing some of your system memory as
"shared" video memory?
