Will DDR2-1066 RAM work at DDR2-800 speed in Asrock ION 330?

Just curious if I can purchase DDR2-1066 RAM for the Asrock ION 330. I know sometimes you can put RAM in the system and it will operate at a lower speed either due to cost or to overclock. I looked all over the net and couldn't find any info on this as the Asrock accept up to DDR2-800 ram but you can over clock the system so I'm thinking DDR2-1066 could possibly work.

Extended SPD probably includes even more. IOW I'd be very surprised if DDR2-1066 won't work at 800 MHz. BTW, don't buy any modules labelled for nonstandard voltages. For DDR2 the highest standard voltage is 1.8V, and any recommendation for a higher one means the chips are overclocked or failed testing at standard voltage. The only exception I know of is Crucial, whose 2.0V DDR2 is supposedly guaranteed even at 1.8V. Notice how Crucial performed much better than other DDR2 brands in last December's review from Tom's Hardware.

As long as the 1066 is not rated >1.8v and not ecc it should work
