I think I still have the DDR(1) version in a system somewhere, and admittedly, the LEDs look so cool. Lexar announced immediate availability of Crucial Ballistix Tracer PC3-10600 (DDR3-1333MHz) high-performance, low-latency memory modules. These modules are the world's first high-performance DDR3 memory modules to incorporate activity-indicating Light-Emitting Diodes (LED). The LEDs on the new Crucial Ballistix Tracer DDR3 modules are illuminated in a random pattern based on memory activity, highlighting the system memory and allowing users to visually see how intensely the memory is working. Additionally, eight blue ground-effects LEDs emit a constant glow near the motherboard memory sockets. Crucial Ballistix Tracer DDR3 memory modules are available in 1GB and 2GB modules, or 2GB and 4GB kits.
