2-3 System Memory Installation
There are 3 168-pin DIMM (Dual Inline Memory Module) sockets on the
mainboard which support Synchronous DRAM and Registered SDRAM, and
allow you install system memory maximum up to 768MB.
2-3.1 Type
This mainboard supports Synchronous DRAM and Registered SDRAM.
However, mixing SDRAM and Registered SDRAM is not allowed. Install one
type only in your system for better compatibility.
2-3.2 Speed
The memory speed normally marked as: -15, -12, -10, -8, -7, PC-100.
The meaning is,
-15 =15ns, and the maximum clock is 66MHz
-12 =12ns, and the maximum clock is 83MHz
-10 =10ns, and the maximum clock is 100MHz
-8 = 8ns, and the maximum clock is 125MHz
-7 = 7ns, and the maximum clock is 142MHz
PC-100 = New Intel specification for high memory speed
With 100MHz or above CPU Bus Clock.
