yea so i bought 2 sticks of 512 XMS PC3700PRO Corsair ram. Both sticks ended up being bad. One of the sticks wont even let my system boot up. The other stick causes random restarts. If i put both sticks in the motherboard so that the memory can run in dual channel mode, my computer just begins to laugh at me. I bought this memory from Outpost.com. Are they pretty good about returns? Anyway, just thought i would share.
