That would be Fast/Wide, or Ultra/Narrow.

(Standard is 5 MB/sec, Fast is 10 MB/sec, assuming narrow, i.e. 8 bits.)

8 MB is the practical limit for the current motherboard design.  In
theory, a new design might be able to use as much as 14 MB of RAM by
extending the fast RAM through banks $80 to $DF.  This would require
changes to the Memory Manager toolset (and would cause compatibility
problems with the TransWarp GS for certain, and probably also the Zip
GS; who cares if we're talking about a faster processor anyway!).
