In the SE/30 the larger or equal memory must be installed in Bank A, which is the four SIMM slots closer to the ROM socket. Perhaps you only installed the 8 MB SIMMs in bank B when you were installing them alone?
The 8MB SIMMs are seen as 4MB because of the way that RAM is addressed. I don't know your level of knowledge so forgive me if I explain the obvious.

Thanks to Jeff for that very clear explanation/reminder of everything I once knew about DRAM addressing, but forgot about 15 years ago. Very helpful indeed.
