2.7 Jumper Settings for SDRAM Clock (DIMM)

Jumper JP4

SDRAM Clock

JP4 is used to set the SDRAM’s clock according to the CPU clock or AGP clock. If you are using PC-100 SDRAM DIMMs, it is recommended that you set the SDRAM clock according to the CPU clock (2-3 On). This setting will provide better

system performance specially when used with 75/83/95/

100MHz processors. However, if you encounter compatibility

problems with PC-100 SDRAM DIMMs or you are using EDO / PC-66 SDRAM DIMMs, set the SDRAM clock according to the AGP clock (1-2 On).
