K i have a Ga-p35-ds3l and I just overclocked my 6400 to 2.88. I had it set at 2.6 for a while and had the memory set at 1to1 with timimings of 4-4-4-10 set manually. However when I set the overclock to 2.88 no matter what I set my timings to it goes to 5-4-4-10. It is stable but I wonder if any knows why this is happening? My memory is gskil ddr26400 with the light blue covers.
