Hello,   One of the tech guys at my office suggested I use a program called CPU-Z to check details about all of my hardware. While using this program, I noticed my PC2-8500 is being recognized as PC2-6400. I didn't know beforehand that a stick of DDR needs to be paired with another stick in order to work at full speed. So can anyone confirm ...

Most DDR2 memory employ one or more SPDs specifications, embedded within the DIMMs themselves.  These specifications let the BIOS determine what speed (and timings too) to run at. Within reason, a mobo featuring DDR2 1066 should run DDR2 800 just fine.  If it's a high-end mobo, you can tell it to override the SPD and attempt to run it ...
