vvga,

Since there are no PC systems using DDR, I assume you're talking about soldered chips. As you yourself have pointed out, there's a big difference in
the difficulty in implementing soldered vs. socketed configurations. Where's the DDR-I in PC systems?


It is not just socketing versus soldering that makes a difference. The biggest effect is the use of memory modules, which add much bigger impedance mismatches because of the tree of connections going from the connector to the individual chips on the module. This creates a large impedance mismatch.
