KTE,seems you're the first one to find a limiting factor on your MSI board.Good going This is probably the case for all 790FX based boards(can we say Phenom has an issue with high HTT clocks and 790 chipsets and we need a high multi-aka BlackEdition- CPUs?).You did a great job for such a small amount of time .

OBR hinted while ago that he could reach much higher on HTT clock using a regular AM2 board(instead of 790 based one)
