Intel 815 Micro-ATX Mainboard
for details), please refer to the table in the next page for details:
Note: When the CPU installed on the mainboard is 66MHz or 100MHz CPU, the
memory frequency will be 100 MHz all the time despite the setting in the
CMOS setup program..
When the CPU installed on the mainboard is 133MHz, you need to pay more
attention when configuring the memory sub-system. please refer to the following
table for the memory configuration.
DIMM MODULES
PC-100 Single-side * 1
PC-100 Single-side * 2
PC-100 Double-side * 1
PC-100 Double -side * 2
PC-133 Single-side * 1
PC-133 Single-side * 2
PC-133 Double-side * 1
PC-133 Double-side * 2
Following is some additional information for memory installation for your reference:
1. When the setting of "System Memory Frequency" is 100MHz, no matter what
kind of DIMM module is installed on the board, it will force the system
memory running at 100MHz.
2. When the setting of "System Memory Frequency" is 133MHz and the CPU is
also 133MHz, then the memory speed will b133MHz be all the time.
3. When the setting of "System Memory Frequency" is 133MHz but the CPU
FSB is 100MHz, then the memory speed will be reduced to100MHz despite
the type of the onboard DIMM module.
