Memory Configuration

The DIMM types supported are EDO and SDRAM. This mainboard has two or three 168 pin DIMM
socket that allow you to install system memory up to 512MB or 768MB.
In 100 MHz system, SPD SDRAM and PC100 specification SDRAM is recommended.
Serial Presence Detect (SPD)
-1 Specification:
-SDRAMS: SDRAM SPD specification Rev 1.1 or later
-2 SPD usage and 100MHz Systems:
-MUST use SPD method to detect/size memory.
-If BIOS detects non-SPD DIMMS (or SPD data is invalid) in a system, then BIOS
should "BEEP" and stop executing POST. –"depends on the factory BIOS setting"
-3 What happens if non-SPD DIMMS are used in 100MHz system:
-BIOS cannot verify if the DIMMS used, meet 100MHz requirment.
-Memory access without programming Buffer strengths FIRST, may return incorrect
data and/or damage the momory
-Incorrect Buffer strength programming for REG. SDRAM.
-CAS# Latency, RAS#-CAS# delay and RAS# Precharge bits will need to be
programmed to lowest performance values
-BIOS cannot distinguish between 2&4 bank 64MB SDRAMS.
