What is the difference between Gold and Tin contacts?
The general overall rule is to match gold leads with gold contacts and tin leads with tin contacts. When you mix the two metals you speed up the natural process of corrosion. During this corrosion process a small electrical current can be formed (much in the way of how batteries work. Batteries contain an acid that is in a chamber with metal discs, the acid excels the corrosion process to create an electrical current.) and can cause problems with the way your RAM functions. When upgrading, confirm what type of connectors and leads you have, then order the same. This rule will not always work since it may not be possible to get the correct match of gold leads with gold contacts and tin leads with tin contacts.
