On a system with four physical slots, there was, and still is a requirement
that memory be installed in matched pairs.. in a three slot system, memory
size can be mixed, but they may have to be moved around to get best
performance.. two slot systems allow for different memory sizes.. again
there may be a requirement to place larger before smaller or vice versa..
It is very much board dependant, and as we all run different boards, it is
difficult to say what should happen without reference to the manual..
The main consideration is that memory is of the same type.. ie. SDRAM pc133
or DDR 2100/2700 etc..
You could always contact Time Computers for verification..
