Hi,everybody here.First of all,need to share the special bios "0052",but very difficult to clock my W3580(=I7 975) ES bu this bios,previousely flash the 0504 download from Asus web,very easy to hit 4.4g @ Auto V-core and V-QPI @33 x 133,try to OC with special bios 0052 @ 22 x200,always get in stuck @ debug code B6 .so anybody can help me with some tips,below is the settings in BIOS:
