Hardware Doctor Question

I am running ver 2.71 Hardware Doctor(HD). My VDDQ reading fluctuates between 1.25 and 1.26 and the lower limit in HD is set at 1.18. I have occasionally gotten a beep that sounds like one of the HD beeps and VDDQ is the only reading close to a limit. What is VDDQ and do I have a potential problem? Thanks.

Try using MBM5 instead of hardware doctor. You can configure all the alarms and gauges to your desired settings. Also show a nice small 'dashboard' of temps, voltages, fan speeds or see them in your taskbar.

Note that there is a special install step for IC7 and IS7 boards.

I'm not sure what the VDDQ is either. I was wondering the same thing and mine also rides on the low side as your does. I would also appreciate some feedback on this issue. What size and brand power supply do you have?

This is the PSU.
