The 300's are different from most of the other machines in the 3000
family. They use std 72pin simms, whereas the 5/6/7/8/900 use propietary
DEC simms. The memory BW is also very different, that is the reason why
the other models need 8 simms per bank, in its day these machines had
pretty good memory BW. (256bit wide I think...)

Cheers!
