Intel takes back lead in U.S. retail

[Grant Schoep]

I recall earlier Windows (98?) would actually slow down if you put too
much RAM on the MB.

My guess is what your recalling was the caching of RAM by the MB. If I
remeber right, older chipsets were setup to cache up to 64 megs, the first
64 megs of RAM, but Windows/DOS, was designed to use RAM the the "top
down", so you would only get cached ram if you exceeded your memory minus
64. i.e. if you had 128 megs, and used 70 megs of ram for an app, only the
6 megs were cached.
