So by my definition (as an experienced ASIC and PCB board designer) they do overclock the DRAM. (I wonder if they test each module across a range of voltage and temperature? Maybe they specify tighter tolerances than Micron.) Since Corsair does guarantee the DIMMs to operate at this higher speed for the lifetime of the DIMM, one could argue that companies should be allowed to be operate the DIMMs at Corsair's rated speed in benchmarks. If they start failing in mass quantities Corsair stands to lose some money, so they are motivated to do a thorough job testing them.
