I've been through two memory boards on my PC/AT which runs at speeds > 9Mhz.
The first was a STB Grande Byte.  It would not boot consistantly at any 
speed greater than 7.5Mhz, even using 100ns chips.  I replaced this w/an AST
Advantage! board, equipped with the daughter board (Advantage Pak! it's called).This combination boots fine at 9Mhz (determined by putting in an 18Mhz crystal).I curently run w/a Mhz Corp. TurboSwitch II set for 9.5Mhz and have had no
problem w/AST board.  By the way, this board is running at these speeds w/120ns
chips.

Hope this helps.
