Re: Z68 extrem3 gen3 55 dr debug fail code
Try booting with just 1 of your 4GB Corsair Vengeance in dimm slot #1 to ascertain if it will boot without giving you the 55 code (memory not installed). If it still fails try the other stick. If it will not boot with either stick in slot #1 either the memory is NG or the boards memory dimm slots are NG. If it does boot with just 1 stick in slot 1 then you might have to manually set timings and voltages to use both sticks since you don't mention if the memory has an XMP profile. I would search thru the Corsair forums for prospective timing/voltages that worked for others that have the same board and try them...
Please keep us in the loop
