Do not mind crio.
I only attack Max Clock at this time, so I can not run SuperPI 1M good speed.
But I make & try to get Max clock very seriously.
I bought over 30 pcs of ASUS mobo what I get very nice BCLK stability one.
(Totaly, I bought over 50 pcs of X58 mobo.)
As you know Bloomfield Max Clock depend on mobo.
If you try Max Clock seriously, mobo is very important.
