CPU VCore and PSU

[digitaloracle]

From my other thread on CPU-Z: Why are my processor temperatures fluctuating so much? Could it be my PSU (which is a thermaltake, not something that came with my case, although I used to have one of those)? Could it be my motherboard?

I have an intel P4 530 processor, stock cooling and clock, the auxilliary power is plugged in, and I get anywhare from 1.2ish-1.6ish (it seems to go to specific voltages, there are some within that range that I have not yet seen, but I could be wrong). The machine runs stable however (I define "stable" as in it doesn't crash overnight)

I must this computer functioning next weekend, so any help is appreciated (if there is something wrong it will take about a week to get new parts).

I wouldnt worry about it too much. Although, generally, voltages shouldnt fluctuate more than 5% from the norm.

If I were to point my finger at what device is to blame, I would blame the motherboard's voltage regulator. The PSU doesnt supply 1.5V, it gets supplied by the mobo.

Thanks. Maybe now I'll be able to RMA my mobo... almost all of the temperature sensors on it are broken . Are voltage regulators normally a problem?

Ok, this issue continues to bother me. Here is a list of voltages I took a few minutes ago:
1.344
328 (assme a 1. before all numbers)
360
344
360
344
392
360
376
328
344
328
344
328
376
328

Each new measumrent is about 1-2 seconds frm the previous one. A few more lists:
392
328
360
344
376
296
408
296
376
312
392
312
360
328
344
328
344
392

And:
296
376
328
376
312
344
328
344
328
344
328
312
392
296

My same questions still apply, and hopelully that data will prove helpful

The Intel website says that the acceptable voltage range is 1.25-1.40V.

Those voltage readings dont seem that bad. 99% of them stay within the 5% rule...

OK, so they dont mean something is wrong, and can be attributed to environemntal things such as the quality of my AC power, although I run it trough a UPS, so that shouldn't be an issue.

Your UPS should be conditioning your AC to make it pretty close to perfect. I think that slight manufacturing flaws are to blame. I wouldnt worry about it.

UPS's are not exactly power conditioners and do a poor job at conditioning power

You are thinking about a regular standby UPS. The standby type just acts passively and controls spikes, etc. Then there is the "In-line" or "Line-Interactive" that will do the above plus filter the AC and adjust as neccessary.

Yeah the more expensive UPS's

Oh well, I need a pair of power conditioners as well as another UPS
