should i try burning in at 2-2-2-11 since it is know that a low tras on a NF2 can make the memory not read the entire cell and have to backpedal to get info?

so could some of the errors i get from burning in at 2-2-2-5 be because the memory dosent completely read the cell and memtest86+ just keeps going and dosent finish reading the info in the cell?

im fin @ 230mhz w/ 2-2-2-5 but that is starting to really push the memory controler on these boards, should i burnin at 2-2-2-11
