I have the G.Skill extreme, though im disappointed between my crucial ballistix doing close to DDR600 2GB's wont obviously OC that well lol
Not bad for the money, went from 230 to 200 in about a week lol. i bought them for around 210.
Getting a good OC, very stable. Love the heatspreaders lol. Works with a lot of voltages 2.5-2.9V. Timings are relatively low 2-3-2-5 DDR500 would be 2.5-3-2-5 i get around 260-270 though my mem dividers dont really work as i want them too lol. 2.8V for me though its like 2.85 really on this DFI mobo 3-3-2-5
