i5-650 cpu only showing one core?

[i.r.id10t]

This is weird. New box, intel i5-650 cpu w/ 8 gb ram. Installed 10.04, did updates from a local mirror, and box is *fast*.

But /proc/cpuinfo only reports one core.

The output of free indicates that all 8gb are recognized, uname reports SMP.

new info dmidecode shows both cores.

Ideas?
