(the web page doesn't mention Ivan> it) Unfortunately you may have a motherboard that maxes at 300 megabit. Our recent testing of Gigabit NICs found more than 75% of the motherboards we tried unable to pass more than 500 megabit and 25% of the motherboards wouldn't pass more than 100 megabit. 300 megabit is about where 32bit 33Mhz PCI maxes out.
