Yeah, but if the socket is burned, you may be shy of a couple of connections. It may be reading the SPD chip fine, but failing to connect to one or more of the chips on the ram stick. You may have to try and clean up the socket in question. Remember carbon conducts! (If it's burned). Also melted plastic may prevent a connection.
You know what I would do? Turn it all off. Remove all the RAM. Get some fine grade sandpaper, fold it over (grit side out), and run it up and down the slot 2-3 times to clean the contacts. Then take a soft paintbrush and dust away any crap from around the sockets, with the board face down, so gravity aids removal. Then I'd try it again. Failing that, new board
(Oh, and make sure it's a known good stick in the slot so you eliminate that from the equation.)
just my 2p's worth
