Great review! I have Crucial Ballistix DDR500 too and I think Crucial Ballistix is a great DDR Module but it requires 2.8v and sometimes you have to set it up manually. Motherboards Manufacturer should add auto-detection and increase the maximum to atleast 3.2v for a better overclock ability. Some of my boards can only reach to 2.8v
I didnt knew the Crucial Ballistix DDR500 could reach 300FSB but I need a new motherboard for it.
