The write speed of the 9200 FlexXLC at 800MHz low latency is appreciable to the Kingston memory and both are far larger than the Corsair offerings. Even overclocked to CAS-3 we couldn't get the SLI Ready Edition modules to do 1T, which means it drops some core bandwidth to the other modules also running low latencies. It's only a fraction faster than the CAS-4/1T EPP settings but both perform less then the rest of the field in raw bandwidth testing.
As the clock frequency increases along with the timings, there's a gentle progression towards a larger bandwidth in Everest, but nothing out performs the modules at ultra low latency 800MHz.
