Comments about Crucial 2GB Upgrade for a Intel DX58SO System:
Used the black 2GB, Ballistix Tracer 240-pin DIMM (with LEDs), DDR3 PC3-12800, NON-ECC, the led's you can see are red and green however the ones that are on the bottom are blue and they shine on the ram slots. which on a black and blue MOBO looks very good.
