another noob question

I'm pretty embarassed to be asking this, as I consider myself a huge geek and whanot building countless PCs. anyways, i'm throwing some ram in the gf's dell because 512 just aint enough.
I remember back in the day, at least being told, that you needed even amounts of ram in the slots, or to only use certain slot configurations on the mobo itself. Was this some BS that i never forgot, or something only affecting older comps?

The ram is going to PC3200 if that matters. going for a 512/256/256 setup, leaving the 4th slot empty. thanks

it depends on the mobo.

a dell (8400). all integrated type deal.

I have a Gateway 500 S from 2002 and it has DDR 512 in one slot and DDR 256 in another and it has run fine for 3 years. Intel 845 mobo.
