SIMM Memory Installation The system board comes standard with 8 MB of memory. Memory over the first megabyte of RAM is extended RAM. The desktop system supports up to 80 MB of memory while the minitower supports up to 136 MB. NOTE: The metal plating on the SIMM stick connectors must match the metal plating in the SIMM sockets of the computer. Use tin-plated SIMM sticks with tin-plated SIMM sockets. 3-14 Options NEC memory expansion options include the following kits. n 4-MB SIMM sticks are 1 MB x 36 bit. n 8-MB SIMM sticks are 2 MB x 36 bit. n 32-MB SIMM sticks are 8 MB x 36 bit. NOTE: The 3 1/2-inch drive bracket in the desktop computers do not allow high profile SIMM sticks to be installed in bank A. 8-MB, 16-MB, and 32-MB SIMM sticks cannot be installed in the desktop's bank A. SIMM Upgrade Path The SIMM kits install into a SIMM socket on the system board. Different size SIMM upgrade kits may be intermixed although SIMM sticks within a bank must be the same size and speed.
