MAX ASYNC LATENCY: 7~8NS
READ PREAMBLE TIME: 5NS

I am using trc 7, trfc 13, max A.L 8ns, read 5ns, but not stable at all. anything over 250fsb wont do PI 32m. I have to set my CPU to 250 and 1:1 to make it do PI 32m... I am trying to use 270 1:1, all the timings post on the other threads not working for me.

currently i have drive strength 7, and data strength 1. is it too low? i tried 8/3 and 7/3 both give error on PI.

any helps please?
some pic might be better
