Ignore the ram for a moment.

I believe the larger refiners survey things like mobos, finger cards, cd/dvd boards, HDD boards, etc every so often to update their expected yields. The reason for that is because the ratio of board to PM yields has been dropping for years. The commonly accepted view is that scrap prices would continue to drop even if the prices of PM's held steady.

Another thing to consider : Calculate the value of a single stick of scrap ram or p-4 style processor. It's pretty small potatoes. These two things have been thought of being the best sources for scrap gold recovery from a computer.
