 No it's a 3.0Ghz Xeon, single-CPU. It also has known errata,
 intel document 302402-023,
 title "64-bit Intel Xeon Processor with 800 MHz System Bus (1 MB and 2 MB
 L2 Cache Versions) Specification Update August 2008"
 
 But I have the latest BIOS and afaik the errata which could explain this
 panic have a BIOS workaround.
