<A HREF="http://www.rambus.com/company/press/pressreleases/2002/020225a.html" target="_new">"The RIMM 4200 uses the 1066 MHz speed bin of current production RDRAM to deliver the highest performance available to date from a single PC memory module," said Tom Quinn, vice president of Marketing, Samsung Semiconductor, Inc. "<font color=red>A single module that supports two channels of RDRAM with 4.2GB/sec of bandwidth makes RDRAM even more attractive from a price-performance standpoint</font color=red>."</A>
So the new 4200 RIMM can allow one module but most don't. Most likely you will need two.
