IIci 64MB memory upgrade issues. Do I have the wrong RAM?

[croissantking]

In reality is this a serious problem to be concerned about? I’ve never read anyone on here getting hold of a machine with galvanic corrosion in its ram sockets… then again, I don’t know how common gold plated SIMMs were. Maybe a good idea to alert the seller of these parts.

The Slaton modules I installed the other day were tinned, so they probably figured this out.

Ages ago I designed a couple motherboards.. (80486 era, so it's been awhile), you pick this stuff up when you sell a few hundred thousand units.

I am no expert on the subject but I do know that old Nintendo consoles used the Hard Gold option on Game PCB's for durability. I mean it makes sense, think about how many times we would insert and remove a game in a old NES for example. Not to mention the obligatory blow into the connector which I am sure would have promptly corroded a non Hard Gold surface finish. (Yummy! We all did it!)

Of course this does not apply to RAM that will spend most of its life connected and relatively untouched.

This is indeed a VERY interesting subject and now I must continue to read and learn! The site that Unknown_K sent was extremely informative. Thank you for sharing that!

You guys (and possibly Gals) are a great plethora of information!

Actually, it does affect RAM. In fact, it affects all components, especially when a computer is turned on and turned off all the time.

The components and the board they are installed into warm up and cool down which causes expansion and contraction which is movement.

That’s why you have to reseat memory in a computer that’s over 5 years old even with gold contacts.

It’s pretty cool stuff. I own a boat in saltwater, and I have to deal with galvanic corrosion.

You are indeed correct! Never though of it that way.
