It looks nice but it doesn't appear to be all that special, judging by the spec numbers. When I think of specialised, enthusiast-grade gaming RAM, I think of low CAS latency with BIG heat spreaders for overclocking. It makes me think of things like the old OCZ Reaper and Reaper-X DIMMs.
Yeah, they're crazy-looking but imagine the overclocking you could do with THOSE heat sinks!
Besides, who really likes or considers ASRock as a contender in todays motherboard race? Their back in the second or third tier at best. The ASRock systems I've built have had to many RMA's for random issues.
