Server vs PC RAM?

[Dimitri]

I see a lot of folks on ebay selling server RAM. Some of the deals are quite sweet so I'm wondering what's the difference between server and PC RAM and is there any way I could get server RAM to work on my PC?

Most of it is registered and has ECC, which aren't supported on consumer platforms.

AMD generally has some ECC support for unregistered DIMMs that protect against bit flips, however.
