DDR2 JEDEC spec only goes up to DD2-800 PC2-6400. So when set to Auto memory settings all MB's will set RAM to 800Mhz. If you look at the SPD tab in CPUz you will see that the profile for 533 is called EPP as it is not JEDEC approved. By setting your BIOS to Manual you can up the RAM to 533 to get DDR2-1066 / PC2-8500 (but also noted that you may need more vDimm too).
