In some cases all three mainboards perform comparably. Sometimes DFI LANPARTY UT NF680i LT SLI-T2R falls behind only MSI P35 Platinum that doesn’t suffer from significant performance drop during FSB Strap changing. And sometimes it even falls behind Asus Commando, which does have a significant performance drop on FSB Strap threshold. MSI and Asus mainboards performed in equal conditions, but even lower timings didn’t help DFI win.
