Most people like Corsair ram better, since they can overclock higher however at relaxed latency, Kingston doesn't do as well in higher latency, but they've been known to be crazy overclockers at low latency. You're talking about 15mhz overclock, why don't you just buy PC3500 ram(guranteed to run at 433mhz), they're not that expensive anymore.
