That is exactly what i read too. I happen to have almost the same board as you, mine is the release edition 680i though, with its problems. Which 2x2024 set did you end up getting. I have to get ram right away and i was looking for something 2x2024.
Edit: Sorry, i know you got the OCZ reaper but i was curious to which model it is ? I saw a lot of different reapers, some at @800mhz and some at 1066mhz.
