Dan(age3): <<If Intel adds support for PC133 to coppermine>> Dan if you had any idea what Intel's vision for microcomputers was, you be dangerous. Since that is not the case, I can dismiss your arguments as easily as I would Dan Qualye. You can not see that inherit limitations of SDRAM begat RDRAM and performance benefits of RDRAM dictated delaying Carmel and Coppermine until they worked correctly with RDRAM.

here is a great take on sdram by a guy who helps me understand the tech side of rmbs. unclewest the Unspoken: because the DDR architecture is stretching the limits of an old technology, it will be very difficult to drive 4 DIMMs at 100 MHz (much less 133 MHz). as a memory component spec, there is no system design to validate that it will work. it is up to the each of the systems companies to solve the quality issues for themselves. the Twisted: using a wide 64 bit data path allows the peak data rate of 1.6 Gbyte/s for DDR, but the limited number of internal banks and control inefficiency reduces the effective bandwidth to 40%->60% or 640->960 Mbytes/s. Rambus DRAM has many internal banks, even with one RIMM installed. this, along with very good signal quality and command control, allow 95% efficiency, or 1.5 Gbytes/s (twice the effective bandwidth of DDR). using more pins, multiple rambus busses can be used to achieve even higher bandwidth. the Unrelated: it matters little whether the end-of-life for SDRAM is 100MHz or 133MHz. the main advantage is that 133 MHz sounds better. it is more of a marketing breakthrough than anything else.
