It's amazing how easy it is to accidentally put DDR RAM in the slot the wrong way around, that's exactly what I did earlier, it resulted in some magic smoke coming from the RAM. and one of the RAM slots pins turning black It surprisingly didn't take much force to insert it incorrectly, and the pins that burnt out are shown below | = normal pin B = burnt pin b = blank ^ = physical key Side with chips ||B|||||||||||||||||||||||||||||||||||||||||||||||||^bb||||||||||||||||||||||||||||||||||| Side without chips |||||||||||||||||||||||||||||||||||bb^|||||||||||||||B|||||||||||||||||||||||||||||||||||| The pin in the socket that lines up with the burnt out pin on the side without chips also burnt out. I'm about to search for an answer to the following myself, but am posting this now to keep all my bases covered, I can buy RAM tomorrow morning, and was planning on attending (my last) LAN (before I move) tomorrow night. So is it safe to try and run new RAM in my mobo (in a different RAM slot). There was smoke coming out of one of the two chips near the burnt pins for the short period before I cut power, now if I turn it on without RAM I get a C1 error from the post port on the mobo meaning bad RAM/no RAM/bad RAM controller and a long beep. The other alternative is to just get a 128MB stick of PC2100 if it might work, otherwise I have enough money to get a 256MB stick. Sorry if parts of my post are hard to understand, I'm a little angry at the moment.
