Manual for ZillioX 5
Memory Configuration
This motherboard provides two 168 pin 3.3V un-buffered DIMM sockets to support a flexible
memory size ranging from 8MB/256MB for SDRAM or from 8MB/512MB for EDO memory.
Both 66MHz/100MHz SDRAM and 66MHz EDO DIMMs are supported. The following set of
rules allows for optimum configurations.
Rules for populating a 440ZX memory array:
l
Pentium II processors with 100MHz front-side bus should be paired only with 100MHz
SDRAM. Processors with 66MHz front-side bus can be paired with either 66MHz or
100MHz SDRAM.
l
NO registered DIMM support.
l
The DRAM Timing register, which provides the DRAM speed grade control for the entire
memory array, must be programmed to use the timing of the slowest DRAMs installed.
l
Possible SDRAM DIMM memory sizes are 8MB, 16MB, 32MB, 64MB, 128MB in each DIMM
socket.
l
Possible EDO DIMM memory sizes are 8MB, 16MB, 32MB, 64MB, 128MB, 256MB in each
DIMM socket.
