Wandering round hall 22 yesterday, I came across G.Skill's stand. G.Skill are a memory vendor who's Samsung TCCD-based modules are very popular among the enthusiast, with their schizophrenic tendencies to run both at DDR400 at low latency and high speed at relaxed latencies and minimal extra voltage. I reviewed a set of their modules recently, along with a few other TCCD-based sticks, and they performed excellently. Sadly, G.Skill confirmed to me yesterday that TCCD is no longer in production, so you might want to snag some of their TCCD-based stuff before it disappears.
