The SampleCell II RAM Installation Guide recommends not to use gold plated SIMMs, based on the following info (from the Intel Web site):"Most Intel motherboards use tin-lead SIMM sockets and Intel recommends NOT mixing dissimilar metals in your memory solution. Studies show that fretting occurs when tin comes in pressure contact with gold or any other metal. Tin debris will transfer to the gold surface and oxidize. Continued transfer will build up an oxide film layer. Tin surfaces always have a natural oxide. Despite this, electrical contact is easily made between two tin surfaces. Oxides on both soft surfaces will bend and break, ensuring contact. The resistance of the oxidation layer builds up over time when one surface is hard. Increasing the contact resistance will ultimately result in memory failures."
