Question about Memory on Asus P8P67 Pro

[ozan2k3]

Asus P8P67 Pro
Can the asus p8p67 pro read data from all RAM slots at the same time or does it have to read only one at a time?
Thanks in advance

As in does it run in dual channel?

As in can it run 2 4gb's(2x2gb) and use all the segments
Edit: don't worry about it, turns out a 2x4gb is faster than 4x2gb anyway
