I wonder about this retail board... the ocp mod resistance was set to 82.5k by default just like the other retail board. I am wondering if there was an update to the new board I have..
The first board came with an early bios that was anightmare.. don't remember the version... this board came with 1.2 by default.. so it must be a newer revision..

maybe Ill return the resistance to stock to see if that helps at all. If ocp has been changed to 300amps instead of the 200amps that I was told.. could help.

I have tried pretty much everthing... Subtimings. Different Multipliers, uncore, blcks.. 5.4ghz is the limit on this board.. I am going to try high vdimm to see if it helps.. I am pretty doubtful though... I also have a new bios to try.. but we will see.
