As of midnight last night EVGA/Nvidia released a new bios - Bios P23 (beta) - that is reported to fix the SATA issues many were having with the EVGA 122-CK-NF68-AR board. A non-beta version of P23 will be released shortly. A full report of the bios fixes will be posted tomorrow on EVGA's community site. If nothing else, EVGA really seems to have their team working to resolve the problems quickly. Maybe they should have done this more before release, but I am still happy to see they are trying to fix their mistake. Let's hope this level of support continues and the 680i reaches its full potential! Initial reports have been mostly positive. See link below:
