Hi, I have an ECS L4S8A2
the thing you have to be careful of is..
- if you use only 1 memory slot, you can run at ddr400 speeds
- if you use 2 memory slots, you can only run at ddr333
- and if you use all 3 slots, you can only run at ddr266 (I found myself having to go down to ddr200 speeds to be stable)
you probably already know that though, since you are talking about 1 stick of ddr400 memory
all I know is that in my personal experience, running 2 sticks at ddr333 worked perfect, and running 3 at ddr200 worked.. for some reason running 3 sticks at ddr266 was giving me problems
I'll try to help u as much as I can.. Not many ppl have this board it seems (or at least they dont post on here), so we use all the help we can get.
