All of MSI's upcoming P55 motherboards will have a "V-Kit", this feature is designed to make it very easy to read out CPU, memory and chipset voltages with a multimeter. A similar feature was already offered on very expensive boards from ASUS, Foxconn and EVGA, but this is the first time a motherboard maker deploys it across an entire range.
Generally multimeter readings are far more accurate than in-BIOS or in-OS readouts, as it can take factors like vdrop and vdroop into consideration to show the actual voltages being applied to the silicon.
It also allows up to two of the CPU voltage, vtt, memory and P55 chispet voltage points to be checked simultaneously because of the access to separate grounding.
