Voltages look good in BIOS so Speccy is wrong.
Disable the Intel onboard chip in Device manger then only the Nvidia card will be active.
I also found the link about BIOS/SMBios: WinSAT (Windows Experience Index) system rating will not run (Windows Vista / Microsoft Windows 7)
I don't see anything in the smbiosreader output that look suspect either but that doesn't mean it isn't there, just not being displayed. No idea how to actually check this other than what you did.
