[net.micro.pc] Expanded Memory Cards at 9 mHz

burgin@ecsvax.UUCP (Robert Burgin) (06/22/86)

Has anyone out there used an expanded memory card with an AT
running at 9 mHz or faster?  I know that some EM boards won't
function beyond 8 mHZ.  Any war stories, recommendations, etc.,
will be appreciated.

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.
