Corsair GTX2 hits 2,200 MHz CAS 6 with liquid nitrogen, triple channel
 

The modules are normally specified to operate at 2250 MHz and 8-8-8-24 timings, or 1800 MHz with 6-6-6-18 timings. Jonas aimed for the best of both worlds and landed at a final clock frequancy of 2204 MHz with timings turned down to 6-6-6-18. This was done with three active memory channels and a memory temperature of -80 grader Celsius, even though the memory voltage was "only" 2.0V.
