User's Manual 12
The HOT-617 mainboard provides four 72-pin SIMM(Single In-line Memory Module)
sockets that make it possible to install up to 512MB of RAM. The SIMM socket support
4MB, 8MB, 16MB, 32MB, 64MB, and 128MB Fast Page Mode(FPM), EDO(Extended
Data Output), and Burst EDO(BEDO).
HOT-617 mainboard supports memory
Error Checking and Correcting (ECC)
function.
To support ECC, the user must use
true
(opposed to phantom parity generated by TTL
chips) 36-bit parity-type SIMMs.
The four SIMM sockets are arranged in two banks of two sockets each. Each bank provides
a 72-bit(with parity) or 64-bit(without parity) wide data path. Both SIMMs in a bank must
be of the same memory size and type, although the different types of memory may differ
between banks.
Table 3-1 listed the SIMMs memory configurations.
