As described two pages earlier we ran into some performance issues when using faster memory settings, so we decided to do a complete benchmark with our Gordian Knot/XVID 1.1.2 test. We can't explain, why it happened. Even by setting all memory timings manually didn't improve things significantly. Our only guess is that the board introduces massive latencies. If this is an bug of the board itself or can be fixed with a BIOS upgrade is unclear. We will try to get a revision 1.01G board, maybe it's a hardware issue.
