support Memory for ECS nforce3-a V1.0

I getting ready to max out the ram on my ECS nforce3-A v1.o motherboard. The book shows to use (2) Corsair CMX1024-3200PT 1gb sticks. Memory that has been test and the board will support the memory. Is there any other memory sticks will work? Is it true that ECS motherboards are very choosing when it comes to latency, latency timing, and voltage. I tried emailing and calling ECS directly, but their tech service is evey poor. They treated me like I was stupped. Good motherboards, poor Tech department. Any help would help. I'm whating to get the memory max out before the World of Warcraft expansion "Wrath of the Lich king" comes out thursday, Nov. 14th, 2008.
