Buffered and unbuffered EDO/FPM memory chips cannot be mixed and they even use slightly different printed circuit boards (PCB’s): If you try to install the wrong type, the first notch on the bottom of the module will be offset. In practice it is better to never use buffered: false. I've found reading even many millions of rows that it is both faster and more memory efficient to use buffered results than unbuffered. Perhaps there is a cross over point if your tables have 500 columns and you're reading 10s of millions or 100s of millions of rows.

Conventional unbuffered memory systems that support DDRn SDRAM can have multiple capacitive loads on the memory bus. Each data bus wire can have up to 2 capacitive loads per memory module (one from a DRAM on the front of the module, and one from a DRAM on the back of the module in the case of a double-sided module).
