Dedicated Micros Motherboards - When One Goes Bad

[JohnHappy 0]

What is the most common reason a DM motherboard goes bad? Perhaps a better way to ask the question is, "When a motherboard gets 'fried' what is the part that normally is damaged?" What is the part on the motherboard that normally wears out first?

 

I have the opportunity to buy a DM motherboard. It does not have the two codec 'sticks' that look like RAM sticks inserted in the slots on the board. I'm thinking to myself, "What is the likelihood that, should my existing motherboard go bad, that the codec 'sticks' that I presently have on the 'bad' board will work in the replacement board I purchased?"

 

I did a Google and eBay search for DM codecs and got nothing. Perhaps the term 'codecs' is not the right term for those two RAM-like sticks standing vertically on my DM motherboards. If not, please let me know.
