Taking their well performing Ballistix PC4000 memory, and adding some wow factor, Crucial seems to have hit something their Ballistix Tracer modules. Price may be a factor for some, as listed on the Crucial website these modules will cost you $23 per 512Mb more than the regular Ballistix PC4000. I was thinking to myself however as I was finishing this article, "What is it going to take to make me take these things out of my case now that I am so used to activity lights on my memory?" I don't know, but I can say I'm looking forward to see more Tracer modules in the future. I can say that if you're a case modder, or looking for a bit more attention at local LAN's for your custom built computer, you're sure to get some heads turning with these in your case, and at no loss of performance.
