Carl,
I should mention that one of the great advances in socket technology was the addition of double "wipes", or contacts. This way, if one wipe failes, the other still provides electrical contact. My guess is that RDRAM would have trouble working with a pin with only one wipe active, as this does change the impedance of the socket. In addition, oxides are a problem, though INTC has gold plated everything.


No need to guess. Just have a look at the Rambus web site and look at

You will see that Rambus connectors are tested at 105C for 500 hours and at temperatures ranging from 25 to 65 C at 90% to 95% relative humidity. Special highlights include the nitric acid and sulphur dioxide tests. Don't forget the 50G shock test and the multi-axis vibration tests of 3.13G RMS acceleration power spectral density for 10 minutes per axis and 2.2G RMS for 45 minutes per axis.

These acceleration spectral densities refer to the acceleration in each frequency band from 5 to 500 Hz simultaneously. Think of your PC bolted to the back of a pickup truck and driven fast down a rocky track.
