Dual channel RAM performance?

[JJR2]

I have the MSI K9N SLI MB for Socket AM2, Athlon 64 X2 5200+, Corsair DDR2 RAM, WinXP Pro. What is the realistic performance gain in dual-channel configuration vs. single-channel for the AMD cpu's and 32-bit OS for typical applications and games?

I read an article recently that stated it was quite small.
I don't recall but it was hardly noticble

I wish I had the article so I knew the tested platforms, etc....

I conducted my own test since I was building a system for a customer with only one stick of RAM in single channel mode it was and easy test to add a second stick and run the test again. However: You have to wonder how much extra performance I got from the 2nd stick was due to the dual channel mode or just the fact that I had more RAM? The increase resulted in approx. 10% better scores on 3dmark.

Ha I believe it was right here on Tom's that I read a similar article of the one you speak. What I do remember from it though that with the advanced caching of todays CPU's and their built in memory management, dual-channel now provides an unoticable performence increase. From the article the dual channel was usually the same, if not, 1~2FPS faster in the gaming benchmarks.

In memory benchies, 50-60% increase IIRC. But who sits there running Sandra all day? In games, 1-5% usually. I'll link the THG article when I find it.
