Indeed the 2007 QuickSpecs of the rx2660 do not list the 9050 processor, the fastest "Montecito" processor.

It should be noted that the rx2660 can also have the more recent Itanium 9100 series "Montvale" processors, running at 1.66 GHz. We see the same thing here: the most recent rx2660 QuickSpecs I have (version 28, September 2009) list the 18 MB L3 cache processor (9140) as the "Maximum", while the 24 MB L3 cache processor (9150M, 9150N and 9152M) is not mentioned.
