help with voltage

post #1 of 4
Thread Starter 
well i just installed a DFI LANPARTY UT nF4 SLI-DR Expert and a Big typhoon on my X2 3800+ but now everytime i open cpu-z my vlotage keeps bouncing up and down from 1.312 to 1.328 is this normal? and temps are @ 22C idle

dont worry about CPU-Z, it tends to read voltages differently sometimes. try a better program like Motherboard Monitor 5 or Smart Guardian (should be on the CD that came with your mb)

What is happening here is that you have a processor with a Multiple VID (Voltage IDentification).

Intel and AMD Processors for some time now have carried a technological enhancement called "Multiple VID". Multiple VID (Voltage IDentification)is a Code Set Instruction for raising and lowering Processor Core Voltages [utilizing a 6-bit digital-to-analog converter (DAC) for Intel and a 5-bit DAC for AMD] housed in the CPU. This DAC uses a VID-code provided by the CPU to program the desired CPU core voltage. Thus the regulated output voltage can be dynamically adjusted by changing the VID-code "on the fly" and giving a "boost' to the core voltage when needed or dropping it when not needed. This helps to keep the processor cooler as lower voltages usually equal lower processor operating temperatures.

You will not have a static voltage with modern processors and any program that gives you a static readout is reading from BIOS the core voltage setttings and restrapping them. Do not trust any program that gives you a static readout of your voltage. The best programs (that I have found) for the "On the Fly VID" are SpeedFan and Motherboard Monitor.

Do not worry about this movement.
