Can the Crosshair IV Formula?

handle 4 GB on 32 bit system. yes I know. 32 bit can only handle a MAX of 3.5. What I want to do is buy a 2x2GB kit and hope it sees the max. I am hoping for first hand knowledge. here. Is anyone that owns a Crosshair IV Formula motherboard using 4GB on a 32bit OS like my 32bit XP SP1. I just don't want to buy 2x1GB and 1GB and then buy the 4 or 8GB kit when I upgrade to the 64bit 7 professional OS. What I don't want to happen is for it to flat out not work. I could of course use 2GB stick in 1 slot but I want to take advantage of the dual channel speed.
