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.

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. 9/15/93 Epson ActionDesk 4000-3
