I have this old computer that always had 2 GB of RAM. I am 100% sure it did. It had 1 GB when new, and we got it upped by the computer shop to 2 GB. Because it is no longer in use, I have done some messing around on it. It has XP, so I tried creating an MS-DOS startup disc. Ever since I ran that it showed 512 MB. I just assumed DOS messed something up. May be a coincidence.
Today I decided to pull everything out that wasn't necessary, and do some troubleshooting with the RAM. I was going to pull both sticks out and put them back in to start. I read the stickers out of curiosity as to the clock speed of them and the brand. And they both read 256 MB.
I am 100% certain that this PC ran on 2 GB of RAM for the years we used it (since upping it). Every time it came on, the first thing the BIOS said was "2GB RAM".
This is one of the strangest things I've ever seen. Can anyone explain how a 512 MB PC could think it had 2 GB?
Asus P4B-M mobo
Intel Pentium 4 1.5 GHz

One RAM module is "Legend 256MB PC133"
and the other "M PC133 256MB 133MHz"
