I have tried another newer version of everest and thath gaved me around 12350 MB/s with 1000Mhz ram and same settings as you, so it´s like Saaya says, it matters what version you use.
I never thought of that, but from now on i will offcourse use the newer version of Everest when posting results.

I will also try the white slots tommorow if i get a chance and see if that makes any diffrence.

Also, i will assemble my QX9650 tommorow for more quad FSB testing, hopefully i can update the first post with some new findings.
