I have one stick of 512 ram on my mobo running at 333mhz. i want to add another one but i have heard this motherboard can have troubles handling 2 chips ruing 333. and you will have to clock down to 266. this does not make sense to me because its made to run at 333 and even unofficially able to run 400mhz. can I run 2 sticks of 333 ddr ram on this board.
