Ram memory with gold colored tin fingers????

[silversaddle1]

Well, here's a new one on me, and I thought I'd ask it around here. I have been told that newer gold edge memory is really tin edge that just looks gold. Now everyone on this group knows I do not refine any of my scrap, instead, I sell it to different buyers. Never once has any buyer brought this matter up on sort. As far as the current sort goes, it's gold edge, tin edge, and RAMBUS. Have any of you guys ran across this yet?

They might be referring to ENIG plating.

I personally have not seen &/or heard about this but it would not surprise me as we know the new the CBs the less PMs we find in them as the companies that manufacture CBs are cutting back more & more on the PMs to cut manufacturing cost

If true then I suspect as eaglekeeper said -------

I have seen this on fingered expansion cards where the fingers have a silvery golden color instead of a true gold color - so it would not surprise me to see them going to ENIG on newer RAM as well - just have not seen/heard of it yet

I have never heard of it either and frankly find it a bit unlikely since it is one of the most critical items in a computer, next to the CPU.
Any errors in the red/write in the memory will crash or invalidate the data in the computer and it have to be done n the correct time frame.

My first computer was a 486DX2 and it had plain solder on the memory fingers (or Pd/Silver who knows) but the timing was stone age comparing to today's memory buses.

Well see, ENIG is what I thought as well, but I would never expect to see that type of cheap plating on memory, let alone on server memory used in enterprise devices. Makes you think that there could be some misiformation out there being used to purchase stock cheaper maybe?

I have seen ENIG on both RAM and grafic cards. Not often but it exists. Quite easy to spot by the colour.

The thickness was defined by something related to "insertion rates" as they were designed to be fitted and uninstalled many times.

Now they really are only fitted a few times so the manufacturers save on the production requirements for the gold.

Nickel plating can be made in such way it looks a bit golden coloured. Trained eye spot this right away tho. But I never run into this type of finger up to this date. Various types of modern pins and connections, yes. Fingers, never.

And as always, you can test it easily if it is gold or tin if you will be in doubt. Nitric tell you clearly.
