Yet another dumb question.

I have Asrock K7S8XE R3.01 mobo and I'm looking to buy some more memory. I check'd asrock site, but didn't find an ansver from there.

I was wondering if my mobo would work with ecc registered memory, and what does that mean anyhow?

Also the memory prices have gone up here (in finland) not sure about the rest of the world, but I was wondering if anyone knows the reason for this?

Thanks for your help.
