None of the residues match for me.
But, it seems to work OK if I turn of the HT... so maybe it's the x64 linpack that's not ready for i7 yet.

Nevertheless, it's a great & easy way to determine your O/C limit on i7 with this tool.
Mine runs for hours at 4.1, but just raising it to 4.2 and it reboots after 2-3 'laps'.
