Your memory is,so so, I have it in my Duron sys. 133x7.5

Have you try'd 133x10 ?

It may not like the 12x setting.

It really all depends on the chip. Thats why AMDs are so great, because you can fool around with the Multiplier AND Fsb, to get 'just' the right settings. So just fool around witha lt untill you get the perfect settings you need.
