Hi. I recently purchased a second stick of 1GB RAM (400Mhz) from Corsair (the same exact stats as the 1GB of RAM currently in my desktop).

I installed the RAM and the computer powered on.

However, when I run
free -omThis is the result I get:


total used free shared buffers cached
Mem: 607 472 134 0 71 176
Swap: 1608 0 1608
Which doesn't sound like 2GB worth of RAM to me.

I was wondering if there was anything I had to do for Ubuntu 10.04 LTS to recognize the RAM.

Not normally. You could try installing memtest86+. Select it from the boot menu (you might have to press ESC to get to it). It will show info about the modules you have installed.

Also check your BIOS to see if it is showing up there.

I'm preparing some pictures to show you what's going on.
I installed memtest86+, and the "show memory configuration" option indicates that there are, indeed, two sticks of 1024MB with 400 Mhz speed.
However, it only tests 624MB. (and usually with 200-333Mhz of speed, so not full speed).
After running the memtest for 66+ hours (don't judge! I was gone all week-end), I did find some errors in the test.
The boot screen only shows 624MB.
I have a built-in video card which takes ~128M of RAM for framebuffer in the BIOS.
I -cannot- find an option in the BIOS to try and manually set the RAM settings.

I'm afraid this may mean a problem with the motherboard.
Let me know what you think. I'll post pictures of this stuff soon.
