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 2 millionth place after the decimal without mistake, it is considered to be stable in regards to RAM and CPU.
We used Super Pi's '32M' benchmark setting.
Super Pi performance is strong on Asus' X79 flagship. Additional memory bandwidth is likely to be part of the reason for the Asus board's performance boost over MSI's entry-level X79 model.
what an amazing board – very very expensive though!
