Well, yes and no.

With 256 K Cache, you can address only 64 MB RAM (hold it in the Cache),
if you have more RAM, you'll experience a major loss of performance, since
half of the time, you may get "cache misses" (No! No ladies for cash!!! ;-) ).

If you want to try this out, disable your cache in you BIOS. This will give
you the same experience *NOW* !!! :-)

Yes - The board manufacturers are trying to spend only as much money for the
boards, as they are forced, to.
