System Memory
The SIMM (Single In-line Memory Module) sockets are divided into two
banks on the system board, Bank 0 and Bank 1. Each bank consists of
2 SIMM sockets. Refer to page 12 for the locations of the SIMM sockets.
You will need either 2 or 4 pieces of SIM modules, depending on the
amount of memory you intend to install. Make sure you insert the same
type of SIMMs in one bank. You can install SIMMs in either of the
banks, Bank 0 or Bank 1, but you must populate one bank first before
going to the next bank.
The 586IHX system board can support 8MB to 256MB of memory using
1MBx32/x36, 2MBx32/x36, 4MBx32/x36, 8MBx32/x36, or 16MBx32/x36
72-pin SIMMs. The table below shows the supported SIM modules and
their corresponding memory sizes.
