What Is My Max?

[Apokalipse]

socket 478 supports a FSB of 400MHZ, 533MHZ and 800MHZ
the older boards that have 400MHZ can sometimes only go up to 533MHZ max (key word: sometimes)
I think your only option is to get a motherboard which supports at least 533MHZ FSB

also, what is your video card?

current video card is an intergrated "Intel(R) 82845G Graphics Controler"
