Once every month we take a look at the SuperPI 32M low clock challenge in our forums. The goal of the challenge is simple: achieve the lowest SuperPI time at 5 GHz clock frequency. In other words, the task is to be as efficient as possible. Long before HWBOT came around, overclockers were already comparing their SuperPI times and tried to out'clock and tweak each other to achieve the best efficiency. In general, most overclockers focus on a light operating system, the perfect copy-waza and of course fully optimized memory subsystem. With Haswell, especially the latter has become an interesting challenge as overclockers "train" their kits to insane frequencies.
SuperPI efficiency is an art in itself. Below you can find the top score from the Haswell SuperPI 32M 5G Challenge thread. Congratulations are in place for the scores below; impressive stuff!
