Hi all; Ptnewell said that PC2100 wouldn't work:
ptnewell, Yahoo RMBS thread, August 23, 2000
... DDR-200 may or may not be practical in a PC. The DDR noise problem is not a fiction of Intel, it is fundamental physics. Specifically, Faraday's Law, one of Maxwell's equations, tells us that the inductive currents (noise) generated is proportional to the voltage swing. RDRAM uses voltage steps of 0.4 volts at a time; DDR uses 2.5 volts/step. This is why RDRAM can run faster and yet be cleaner. DDR-266 is quite improbable in a PC setting. Unfortunately for DDR, basic physics cannot be finessed.
...
Since DDR has 1/4 the bandwidth, lacks granularity/scalability, has the same production costs, has much higher design costs, the outcome is quite clear.

This post is from long enough ago that the full depth of ptnewell's delusions is clear. His more recent postings will look as silly, 6 to 18 months from now, but the above is already a classic.
