> I need cd intalation for put work the RAM, or windows detect alone?
Windows is an operating system. To identify the
OS we can key (in DOS) command VER or else
in Windows do / start / settings / control panel / system.
When RAM chips are in a PC, the BIOS (shown
at boot) displays their number and a couple more
details. This occurs before any OS is loaded.
We do not need an OS installation CD for either function.
