The P6T6 doesn't read or display cpu vtt in any bios monitoring or pcprobe/everest windows app.. I'm only going by what i need to set in bios for cpu vtt (qpi/dram). Yeah not entirely accurate but when DFI UT X58 needs 1.4-1.5v CPU VTT to do a certain setting vs P6T6 WS Revo needing 1.6-1.65v CPU VTT to do a lower but close to same setting - that's what I'm basing my statement on. But still early days with P6T6 WS Revo - new 0601 beta bios has improved things somewhat but need more time to tame the beast
