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.

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.
