yeah, the 32 bit doesn't see more then about 3 gigs of ram. I just added a second 2gb. stick so I could utilize the dual channel feature of the motherboard since it will still, allow dual channel operation even though all the ram is not recognized. I was surprised, to find out nero 7 or 8 would not function with even, a full 3gb. of ram being seen. it will, if the graphics on board use up some of the 3 gigs. of ram. otherwise, the burn at once feature can not be used and takes much, longer to burn a dvd. without it almost three times on average. Thanks!
