Weber believes as many as 20 percent of the roughly ten million servers that ship a year could be candidates for his memory-expansion technology if they can accommodate DDR2 DRAMs. "We thought we would have to aim this solely at AMD-based Opteron systems, but halfway through out project Intel told us they were working on a registered DIMM platform," said Weber. Intel has pushed hard for an alternative to DDR2 it has developed called fully buffered DIMMs. However, some OEMs have pushed back on the technology. "Many OEM were not happy with the power, cost and latency issues with FB-DIMMs," said Suresh Rajan, the co-founder of MetaRAM who previously helped launch NVidia Corp.'s server chip set business. "One OEM said he had to redesign his whole chassis to accommodate FB-DIMMs," he added.

So even Intel is on board. FB DIMMs certainly are Rambus 2.0.
