Question about CPU-Z

post #1 of 2
Thread Starter 
I just finished installing windows last night (upgraded to P5LD2 mb) and then installed cpu-z. At first the voltage for cpu was fluctuating because the C1E and TM2 functions were enabled. I disabled both, and when I checked CPU-Z, it still showed fluctuation between 1.27 and 1.46. On my Abit AS8, I noticed a flux but that was because there was no option to disable C1E or TM2, and the multiplier would switch between 14 and 17. Now on the asus, when multi is locked at 17, the voltage still flux. Is CPU-Z know to not be too acurate with certain boards? I tested it on my PC at work and CPU-Z has the voltage at 3.6 for a P4 540.

CPUZ isnt very accurate when it comes to reading voltage's, its close but not very accurate, if you are getting voltage fluctuations it is likely that the board has some voltage droop. Download a program called speedfan, and see what that tells you. In most case's the only accurate way to read voltge is with a multi meter on the board. If this was a P5WD2 E I could post a picture of where to get the actual voltage from. This board stock has some serious voltage fluctuations as well and has realy bad Vdroop, I have since fixed the Vdroop and this has stopped the voltage fluctuation.

Also if your work PC is reading at 3.6 it is likely a bug in CPUZ as its trying to read 2 Vcore when clearly there is only 1. But it doesnt raise some questions. What is the voltage set at in the bios of the 540? CPUZ shouldnt read it at any more then 3.0 or 3.1 which would make it around 1.55 Vcore and thats kinda.

First picture is of the Vcore droop before the mod, and the second is after the mod.
