SIMM Installation
Your computer comes with 4MB of memory on a SIMM. You
can increase the memory up to 64MB by installing 1MB,
2MB, 4MB, 8MB, 16MB, and 32MB SIMMs in the computer’s
two SIMM sockets. The following table shows the possible
SIMM configurations; do not install memory in any other
configuration.

Epson ActionDesk 4000
Use only tin-plated, 32-bit or 36-bit, 72-pin, fast-page mode
SIMMs that operate at an access speed of 80ns (nanoseconds)
or faster. Be sure all the SIMMs operate at the same speed.
SIMMs that are 80ns must operate with 1 wait state; 70ns or
faster SIMMs can operate with 0 wait state. (To add a wait
state, select the DRAM wait state option from the
Advanced Chipset Control option in SETUP.)
Video Memory
The ActionDesk 4000 comes with 1MB of video memory. You
can increase the video memory to 2MB by installing two
video DRAM, 40-pin, 256KB x 16-bit, ZIP (Zig-zag Inline
Package) chips.
For the memory to work properly, you must install one chip
in each socket.
