I just read
polarbee's post and I remembered a funny story. When I got out of college I got a job as a part time tech at Best Buy until I could find something full time. This is about the time that DDR memory had taken place over PC100. Why do I mention this, you'll find out in a minute.
My first day on the job and I had to do upgrade a computer's memory. Now at this particular Best Buy they have the "tech bench" in the middle of computers. So that customers can be all mystified when you open up their machines and ask all sorts of questions. Which is a real pain because all I want to do is be left alone and fix it.
Anyway, its an E-Machine. The customer is very happy about this because he got the very last of the older model. Apparently it had a better video card or something compared to what was coming out. So I open up the machine to put the RAM in. Now it had been a couple months since I had upgraded the memory on a PC, and the last time it was PC100. You cannot screw that up. Because it had the 3 connectors (blanking on the real name) that plugged into the slot. Small, medium, and large. But the DDR sticks only have 2 , one bigger, and one slightly smaller.
So I plug the RAM in the 2nd slot, close it up and turn it on. Hmmm...won't Post. Wait, whats that smell? I look over and there be smoke coming out of the brand new E-Machine!
I unplug it, open it up and I've fried the RAM and the motherboard. Did I mention this was my first day?
One of two things happened:
1) Defective motherboard
2) I put in the RAM backwards. Although even if I did that the result should not be fire
I'll never know because the RAM was pretty much a briquet. I was slightly mortified by this, fortunatley no one cared and everyone thought it was hillarious. Tower got sent back as defective. Customer wasn't thrilled at first until I explained that this could have happened when he was at home instead.
