does anybody know this issue? please read------> i have preinstalled pc2700 RAM that is 256MB, run at 166MHz. when i installed the two (2) 512 MHz with the same amount of speed, the system only reads 133Mhz which should be 166Mhz/333DR. Is there anyway to correct this using the BIOS? please help. I really need to resolve this issue. Thanks in advance for those who can save me from this fog of confusion. ;(
