Hi EMC2, thanks for the info. I'll try to post the pics correctly. This is p...ing me off!
Yes, I had a good scope, a Tektro (a TDS xxx) with a 400MHz bandwidth.
No, the probe was not connected perfectly. To measure the Vcore at the CPU socket, I soldered two wires of good diameter to the back of the mobo (CPU socket) and twisted paired them for about a foot to a terminal block where I was connecting the scope probe. I figured that most of the noise that would couple to the wires would be common mode (coupling on both + and - wires and therefore cancelling itself). No current goes through the wires, as they are only used for probing.
The probes come with the scope, they are x10 with a 10pF parasitic capacitance.

You seem to have very good knowledge on the good useage of a scope.

I took real-time data. What is the "equivalent" mode?
