I cant find the 3500C2 anywhere for any reasonable price and I cant find anything about it being discontinued... I've seen some 3500C2PT (talkin about the Corsair XMS 3500) and I think the only difference between the 2 is color of the heatspredder. Anyone know if I'll have a problem running 1 stick of the C2 and 1 stick of the C2PT on a IC7-G?
