Well, I don't have this ram but I did buy a generic high density 64 x 4 512 mb pc133 dimm for my KT7 (no a) and it is 8 ns as well. I think there was a time in the memory industry that 8 ns was frequently classified as pc133 pretty much across the board. Anyway, this works fine with 4 way interleaving, 4k page mode, normal settings but no o'c. YMMV
