This one is 2.0 μF the other one is 1.5 μF. It seems like a difference bigger than just a tolerance issue.
I'd be more up for the adventure and testing your higher Farad theory if an expensive motherboard wasn't in the line of fire haha
I might do some googling for the dimm specs. Not even sure how I would approach Samsung about getting those details, the pcbs don't have labels so I would have to send pics and draw circles around the ones I need lol
LOL... ok, so before you take anything i say seriously, know that i have lot of friends who will not take my advice. But then again, I have more fun than they do...
To me the difference between 2.0 and 1.5 microF (how did you enter the mu symbol here?) is not much... if it were at least an order of magnitude difference then maybe i would be more concerned. I don't know what that capacitor is used for... but these are not likely high voltage situations on a DIMM. Who knows, maybe the higher capacitors will allow higher RAM overclocking! LOL
When I contacted 3ware, I just called their tech support and they emailed me the specs and a list of manufacturers they use and their part numbers. That might be unique to 3ware as I think they were a smaller outfit back then. Not sure how Samsung tech support guys will respond when you ask them for the specification of a capacitor on their DIMMs...
Again, I'm not an EE, I have degrees in physics and applied math and I like to tinker so I understand some of the theory but I don't always know what I'm talking about. My gut tells me to do things I can't always explain and more than half the time things work! I've fixed a RAID controller, some gigabit switches, car audio electronics, and some other stuff with my gut and i got lucky. but this is getting off topic....
So, I guess all these sellers on ebay selling "as-is, not working or for parts" stuff are just betting on people who like to gamble and see if they can score expensive computer parts for cheap?
