Super Pi is used by a huge audience, particularly to check stability when overclocking processors. If a system is able to calculate PI to the 32 millionth place after the decimal without mistake, it is considered to be stable in regards to RAM and CPU.
The 12 minutes and 29 seconds achieved by the i5 660 and DH57JG is an impressive time for these components and is better than we achieved with the quad core i5-750.
