|Make sure you understand what I wrote above. If you're going to run the 32-bit version of XP or Vista, they will NOT recognize more than 3.5GB. Even if you install 16GB, the system will only use 3.5GB, so hopefully you know what you're doing. And obviously, you can't run in dual channel mode if you only have a single stick.|
Why that board anyway? It has a good northbridge but an old southbridge. See if you can find one that uses the SB700 or better yet, the SB750. The Gigabyte GA-MA790X-UD4P would be a better choice.
Here's some RAM...it's very pricey, plus it's ECC. It's not performance RAM, it's more for server use, but that's what you're gonna get with sticks that size.
