It supports it, it says so on there web site. I think they used the crappy ram because it was cheaper. Even with the slow ram it does pretty good on the benchmarks. + if you have a little money, you could swap out the RAM and HD, and put it in another system. Then buy some good quality RAM and a 300GB HD, and still be around $2500
All in all, this is a really nice computer. I hope we see more like it.
