Memory Upgrade Socket |
Note |
| This motherboard does not have any built-in memory. However, the system is usually shipped with 8MB of EDO memory, taking up the first bank (BANK 0) with two 4MB SIMMs. |
Socket Orientation |
| The socket closest to the CPU (leftmost socket) is J10F1, and the one right next to it to the right is J10E1. These two sockets make up the first bank (BANK 0). The next one over to the right is socket J10D2, and the right most socket is J10D1. These two sockets make up the second bank (BANK 1). See Also Ram Upgrade Information |
