A couple of Swiss overclockers set a pair of memory overclocking records using a 2GB dual-channel kit of Kingston's high frequency HyperX DDR3-2544 memory (KHX2544C9D3T1FK2/2GX). It's the fastest dual-channel memory kit around, and thanks to Roger Tanner "splmann" and Marc Voser "Besi," it's also the kit responsible for setting frequency records at CAS 6 and CAS 8.
At CAS 6, the overclocking duo pushed the kit to 3095MHz, and at CAS 8 it topped out at 3175MHz. These are the fastest frequencies ever for each respective CAS latency.
It's no shocker that it took some serious cooling to set these records. The team used liquid nitrogen, first fixing the memory slots in a cooler made from aluminum and copper. Kingston says the cooler had a basin at the top, which was filled with -196C liquid nitrogen.
