Answer» My voltage never seems to make it above the voltage stated.
This screenshot was taken in Sisoft Sandra. The same readings are ALSO displayed in the BIOS. Both in F8 and F14.
Installed is a Gigabyte 7N400 PRO mainboardwith BIOS F14 (Latest version)
And the power supply is a Q-tec PSU 400WP Dual Fan Gold
I donot know what to think of this. Less voltage means less strain on my computer parts. But could it also mean less performance?
Is this something I have to investigate?Raptor.......Some of your voltages look a little low.....
Here's what mine look like........
Monitoring Chip : Via 686A/B
Vcore : 1.78 V
Vcore1 : 2.6 V
+3.3V Voltage : 3.39 V
+5V Voltage : 5.08 V
+12V Voltage : 12.48 V
Processor Fan : 4787 rpm
Processor Temperature : 32.8 °C
Mainboard Temperature : 22.6 °C
Power/Aux Temperature : 37.5 °C
Hard Disk Temperature #1 : 42°C
Perhaps its time for a new power supply.
check you motherboard specs and see what it says re the voltages .
Hope this gives you a idea......

This power supply came together with my mainboard. Both are approximately a year old.
I see that your voltages are above the settings stated there. A friend of mine has shown me that his voltage settings are also above the voltages stated.
I have never read any information about mainboard voltages in the manual that came with my mainboard. I shall contact Gigabyte Tech-support to see what they can tell me.
are these problems that OCCURS with a failing power supply? As far as I recall, this has been present ever since it was installed. And I never had trouble with my power supply. No failures, no shortages, nothing.
I think it's far more likely your motherboard sensors are reporting the wrong figures. They are usually FAR from 100% accurate. I have the same motherboard at home however, and I'll have a little look to see what mine reports, and then I'll get back to you. I would imagine SiSoft Sandra takes its readings directly from the motherboard sensors (I would in fact be sure of it) so its little wonder they report the same.
Your problem is very unlikely to be a failing power supply - if it was you would likely be getting crashes and lockups. On the other hand, if you have other reasons to be worried about your power supply do yourself a favour and turn your computer off, and don't turn it back on til a new power supply has been installed. I had to replace my motherboard recently when my Power supply went, and the same for a friend of mine a week later. Not worth it. I'll never again trust a PC to a cheap power supply.
Keep in mind also that 12V is never quite 12.00 volts, a small variance either way is perfectly acceptable. Your 3.3V rail looks fine from the report, but your 5V and 12V do look a little low. But again, it's most likely a reporting error.
Edit:
OH and don't bother checking your motherboard specs. All computers are designed to distribute near identical voltages (which is why there is no difference between power supplies, RAM, PCI cards, HDDs etc as far as voltage is concerned. CPUs are about the only things that differ in voltage from one to the next).
How do I determine wheter it is a reporting error or not?
Well, probably the easiest way to tell would be with a multimeter against one of the molex power connectors (the rectangular-with-cut-off-corners you whack into your IDE devices). Otherwise, you're outa luck - the only other way is the computer's BIOS reporting mechanism.
I'm home now - now I realise we have slightly different boards - mine's the Pro2 version of your board (FC BIOS version for me) which unfortunately reports voltages as "OK" - no readout. This is possibly because they found the original board (the PRO) version was reporting voltages incorrectly (?).
If you do have a multimeter, connect it to the molex connector (yellow-adjacent black or red-adjacent black (blacks are ground cables always in computers). I'd choose yellow-black as these are the wires used for case fans that run of molex connectors.
I'm guessing its definitely a reporting error though. Look at your 5V power rail = you're virtually 20% under!!! I'd imagine you'd be having all sorts of problems if you were under by this MUCH!
The other thing I'd use to test, is if you have a second computer, rip the PS out of this one and shove it in the second - see what voltages PC #2 reports. I bet they're (significantly) different.why do people reply on meters so much all of them may be a fault?and who does determine whether the meter is acccurate?what is your system maybe its made to run hot or cold...what is your problem..with it..if there is no problem why have you posted?and what results do you achieve from aida32 or belarc if pc makers had a problem with overheated where is the gauge pass...the tolerant for pcs has to be in the making of them therefore this question is invalid and has no relenvance at all...this question has been posted before.....why..variants may apply cable batteries used etc..v

Well, people rely on meters because they give you an objectively measured figure against which to make judgements. Meters measure. Measurements are useful.
The meter is accurate if it's properly calibrated. Generally, cheap meters are poorly calibrated and more expensive ones are better calibrated. Machines need to be regularly recalibrated to ensure they are accurate.
While it's possible to make your machine run colder by undervolting - I wouldn't recommend it and most people wouldn't even think of it.
Maybe Raptor doesn't have a problem. Maybe he's just curious. Or maybe, like his original post stated, he was worried his power supply may be on the way out.
The question isn't irrelevant unless the asker didn't want an answer. I'd be more tempted to say that replies questioning the questioner are irrelevant unless they are well informed, possibly by a psychic talent.
It's also handy to revisit old topics sometimes as situations change, and new and/or different people have different pieces of information to offer.
I'm not convinced your post offered anything of value, Merlin.why have you answered it...........meters are not accurate...just guess work..like time itself man made.etc..and why hide your email i do not?cia fbi mi5 so oh powerful one what is the answer to raptors post...i await you response to it..have you dug up farraday?

I answered because I thought I had something worth offering the thread. Meters ARE accurate if calibrated and used correctly. This is how man has discovered much of the natural world, through scientific rigour, through the ages. {Aside: I'm not trying to assert science is perfect. That's another question entirely.}
I don't 'hide' my email, I avoid spam. I will send you an email from my email address so you know it, if that is what you wish. I'm certainly not hiding from yourself or anyone else (why would I?).
Merlin - I'm not all powerful. Never claimed to be. I'm certainly not a member of the FBI, CIA, MI5 or any other secret service agency (over here in Australia, its ASIO amongst others).
I was trying to answer Raptor's posts with what I've been posting. I thought you weren't trying to answer the posts - which is why I posted what I did. Your post didn't seem to answer his questions so much as question Raptor himself, and his motives for posting. I did not and still don't think that's offering anything constructive to the thread.
I am aware of Faraday and (some of) his contributions to the science of electricity. I'm not sure exactly what you mean by what you've said however - perhaps you can elaborate?
It's obvious you took offense at my post - no offense was meant by it. I don't see how you could take what I said personally - but nevertheless I apologise for the offense caused. Again - it was certainly not the intention.They should change the title 'Computer-hope forum god'
Some people take it a tad too literally.
Ofcourse, my question has been previously asked and probably even answered.
So have many other questions. I donot see you bad-mouthing the people asking them or the people trying to help those people.
Do you have a problem with me, sir?
let us know
