Wouldn't that mean that a shortage of DRAM chips should cause price difference in all of them? Not sure that'd explain why RDIMM prices aren't raising as sharply as UDIMM. That the fab and assembly lines have transitioned into making other stuff makes sense why'd there be a difference though, as bradfa mentioned in their reply.
