Jeff, I truly appreciate your extremely layman-friendly explanation. I don't know what you do, but have you considered technical writing as a career?

I'll have to order the 16x8 DIMMs to be sure, as I still haven't been able to ascertain the configuration of the chips that I have that work well. (Is configuration the right word to refer to the 32x4 vs 16x8 difference? I've seen the word architecture; is this the same thing? Is there a better or more usual term?) Am I right in guessing that even if a computer could use either kind of memory, it would be best not to mix them? You wrote: >A 32M X 4 chip would have 32 million addresses but each address only > stores 4 bits. So it takes sixteen 32M X 4 chips to create a 64 bit > wide DIMM. So sixteen 32M X 4 chips forms a DIMM of 32 million X 64 bits > or 32M X 8 bytes = 256 MB. So when I see 32x64 in memory item descriptions, this probably means 32M x 64 bits but what would 32x64-8 mean? That's what it says in the item description for the memory recommended by RAM Direct for a B&W G3. Thanks again for all your help! Joy -- G-List is sponsored by <http://lowendmac.com/> and...
