The 486 computer I had back in 1992 could support up 16 MB of memory IIRC. It was clocked at 25 MHz, but I did get the math-coprocessor and upgraded it to a DX4 75 Mhz. I knew of some models that could support up to 32 MB of RAM, but I wasn't aware of any that would support 64 MB of RAM (which was quite expensive at the time).
