 That 486SX/25 motherboard uses memory interleaving to achieve reasonable
executation speeds. This is the same design that was used in the 386DX/25
motherboards. When you do decide to go to the higher clock chip, the chip
is going to have a tremendous performance degradation because there is no
secondary cache.
