Changing the refresh rate will NOT buy you any performance gain.
The only reason to put faster-access DRAMs in your system is if
you can also decrease the number of wait-states added to memory
cycles by the DRAM controller.  Typically the wait-states are
hard-wired into the DRAM controller (they assume a certain speed
DRAM), but some controllers have programmable wait-state registers.
You should try to get a Technical Reference Manual from Tandy (if
one exists) to find out if there's any way to change the wait-
states.  If you can't change 'em, don't waste your money on the
faster DRAMs -- your system will still assume you have the slow
DRAMs.
