you may need to flash to the latest BIOS revision...

(and for future reference, there is no need for two threads on the same subject )

ensure that you are using the right timings for the RAM (lower the timings and then set the RAM to 1066) (the higher the speed the more lax the timings need to be [e.g. you may have RAM running at 4-4-4-12 @ 800, but for it to run at 1066 the timings may have to be 6-6-6-15 etc])
are you using the correct voltage settings for the RAM?

All boards default PC6400 and above RAM to the settings you no doubt have. This is because PC6400 is the fastest official speed of DDR2.

At the voltage rating on the label of the RAM and the timings they are rated for (5-5-5-18?) you should have no problem running them at that speed.
