Today we have a look at the SuperPI 32M low-clock challenge threads in our forum and make a list of the most efficient overclocks for various CPU architectures. Not much has changed since the previous update end of April as only Bullant took back the top spot in the Haswell category. We look forward to the launch of Sky Lake in the near future to see crazy new SuperPI 32M low-clock results! In the Zambezi category we find Splave.rom hammering the top score by improving Sburnolo's previous best by nearly 40 seconds!

Congratulations to all the leaders in their specific categories!
