I reinstalled 7.64 and I got some VRM readings but they were all over the place and incomplete, this corresponds to the debug file with the ending _7.64. After rebooting there were VRM readings that were all 0, corresponding to the ending _7.64_2.Also please try this build: www.hwinfo.com/beta/hwi64_765_5242.zip
and let me know if it fixes the problem. A Debug File might again be needed to analyze the details.
