How about these voltages, they seem normal to you?

I've been running OCCT today and noticed that some voltages are... not in the normal range.
Could this mean faulty PSU?
Thanks for your response!



More about : voltages normal

You need a volt meter to get the right voltages software is not accurate.

OK, I understand that. But my problems with random GPU freezings and now such low numbers, could this be related? I know it's hard to say, but still. How much off can software readings be?

Yes, this looks like a dieing PSU from what you are showing. The software should not be that far off to show your 5V line at 3.4V. That risks damaging parts in your computer. It shouldn't be more than +/- 10%.

Well, this is from my bios...

Try one last look at the voltages, 'cause those look so bad that the PC shouldn't even be turning on!
Re-boot and go into the BIOS/UEFI and there should be a tab for hardware or hardware monitoring; see what the voltages are showing.
Then try this monitoring program: http://www.hwinfo.com
HWInfo64.
It seems to be more accurate then the others I have tried.
If all the voltages STILL show low, especially in the BIOS monitor, you really need a better/new PSU, and quickly before major parts get wrecked.

Those look good. Try the HWinfo64 see what it shows with everything running.

Did that, looks much better, doesn't it?

Yes, looks much better. The PSU isn't completely off the suspect list yet, cause parts inside can heat up and cause malfunctions, but the cause of your GPU freezes are probably not power related.
What does your video card temp look like on this monitor? If you can't watch it during gaming, then play hard and see what the maximum was. The temps shown here don't look bad, so I will assume you have cleaned the interior of your case and especially your CPU cooler and video card.
Have you updated your video drivers? and did you do a clean install?
What game is freezing?

Just so you know, an occasional freeze (and by that I mean maybe once per month or less often) can happen in games: locked my pc up solid two days ago playing Crysis2 and I have know idea what I did to cause it. Had to reboot and all is well (played for 3hrs. last night, no problems).

OCCT uses the same sensor interpretation engine as HWMonitor. There are a lot of sensor chips that it doesn't properly support.

When that happens you need to find a utility that properly supports the sensor chip on your motherboard. The motherboard manufacturer's utility should always work.

Commercial utilities like AIDA64 have always worked for me where HWMonitor and OCCT have failed.

Freeware utilities like HWiNFO64 will sometimes support more sensor chips than HWMonitor's engine.

huh, yeah, I used MSI afterburner, everything seems to be in perfect shape hardware-wise.
I've been writing a ful detailed report and what I've tested/tried here, feel free to read http://forums.guru3d.com/showthread.php?t=393538

Worth asking: are you running GeForce Experience? If so, try uninstalling it.

OK I ran OCCT with HW64, which displays correct voltages, and even under pressure everything seems stable:

If your voltages fall within the ATX12V Power Supply Design Guide Specifications as shown in the following table then your PSU is fine:

OK guys, I think I MIGHT BE onto something here.
I ran "HWiNFO64.exe" while playing a game, and of course, it crashed soon afterwards. I analyzed the data and found out that just a second before the crash, all 4 cores drastically lost voltages!
Also, core ratio [x] (not exactly sure what is, though) dropped from 36 to 8 second before the crash.
GPU voltage WAS STABLE before the crash! CPU voltages WEREN'T

Please, if anyone has the time, check this data and provide your conclusion.

scroll down to rows 711 (before crash) and 712 (actual crash), they seem significant to me, before that moment everything was alright.
