|It will work as long as it's a Pentuim 4 533mhz FSB version or lower. If it's a Pentuim 4 800mhz FSB version it will not work on an 845G chipset.|
Check the spec number on the Pentuim 4 processor to see what version you have. For example "SL6K6" and go here to see which model it is and rather or not it has a 533mhz FSB or an 800mhz FSB.
