You need to set the FSB to 133 to run your memory at 166. Performance mode needs to be set at Auto. If you leave it in Standard or Turbo it will run at DDR355. Use cpuz 1.18 to check your memory speeds in Windows. For some reason at 133 FSB with Standard or Turbo mode, memory multiplier is at...
Does anyone have high mb temps for this board. I have seen mine skyrocket to 49c in asus probe. Most of the time it is hot as my processor temps. I have 80mm intake and exhaust fans.
The weird thing is why turbo mode turns off when the bus speed is higher than 133. When the FSB is at 140, I get 2.8 Ghz. However, the memory registers at 175 Mhz and the performance is on the same level as running 133 FSB.

Does anyone know how the turbo mode works? My system is running a Northwood 2.0 at 2.66 Ghz. With turbo mode on it runs the memory at 133 Mhz 2-2-2-5 by SPD. My sandra score is in 2711 Mbs. That seems pretty fast for DDR266. But manually tuning the memory or going higher than 133 FSB drops...
