G486VPB
Memory Installation
The G486VPB system board can support 1MB to
128MB of memory using HSIM modules. HSIM is an
acronym for High Density Single In-line Memory.
A SIM module consists of several RAM chips soldered
onto a small circuit board. A SIM module connects to
the system board via a 72-pin card-edge connector.
The SIM sockets are divided into four banks on the
system board. The G486VPB uses 256Kx36, 512Kx36,
1Mx36, 2Mx36, 4Mx36, 8Mx36, or 16Mx36 HSIM
modules installed in four banks. Non-parity (x32)
SIMMs can also be used if parity checking is turned off
in CMOS Setup.
You will need 1 or 2 pieces of SIM modules, depending
on the amount of memory you intend to install. The
following table summarizes the bank locations and
modules needed for the corresponding memory sizes.
