I just received a second set of Crucial Ballistix Tracer 1GB x 2 ddr2 PC2-6400. I loved my first set but this second set looks cheaper. It only has one set of LEDS instead of two, it's single sided instead of double sided and there are no clips holding the heat spreaders on like the older set has. I haven't tried OCing them yet but I'm wondering if Crucial went cheaper with the chips also. My old ones would go to 1066 easy. Has anyone else ordered any Ballistix Tracers lately and recieved these cheap ones?
