Like other Crucial Ballistix Tracer memory the Crucial Ballistix Red PC2-6400 4GB Memory Kit looks amazing, compatible, reliable, stable and overclockable. Speaking of overclocking, I was hoping to get a little more out of this memory but 4GB kits generally perform a little worse in the overclocking department than 2GB kits.
Crucial has always impressed me with their prompt service and memory support. Of all the memory I've reviewed it's by far the most compatible which is fundamental when choosing memory. While DDR2 is getting a little dated it still has amazing performance, even when compared to DDR3 memory. DDR2 memory still tends to overclock better and has a much better timing than DDR3. And that's the reason why it's still preferred by many, not to mention it's very affordable. If you're in the market for quality DDR2 memory I'd strongly recommend this product.
