I think there is an OVP at 1.9V so I don't really know why they allow up to 2.4V through BIOS.
Here are some initial results with Prime95 V25.5 Blend test:

Max FSB in Cinebench 9.5 (nice application for checking stability, if it passes it can most likely pass 3DMark06 aswell):

CPU-Z shows about 0.1V lower than the DMM.
BIOS Voltage settings except for Vcore and Vmem:
CPU PLL Voltage: 1.60V
CPU VTT Voltage: 1.50V
NB Core Voltage: 1.20V
SB Core Voltage: 1.60V
1.2V HT Voltage: 1.40V
Bridge Core Voltage: 1.20V
CPU + NB GLT_REF = Auto
