PSU Voltage out of normal range

[Aeglos]

Hello folks

I've been experiencing blue screens of death and sudden shut downs since last weekend. Tride many diagnoses and notinhg seemed to explain it. Until I got Everest and Speedfan to see how my psu voltage is.

Readings are almost the same in both programs. This is the big problem....

Vcore1 1,02
Vcore2 1,14
+3.3v 1,60
+5v 5,05
+12v 4,74
-12v -4,13
-5v -0,78
+5v 5,54
Vbat 3,39
GPU Vddc 0,95


As I am realy a newbie to psu problems, I would like you to tell me how screwed I am. Because I can't afford to change psu this month and I really need my pc in my work.

Thank you for your attention

Software readings are almost always inaccurate, as in this case. Just completely ignore those numbers, and if you could tell me your full specs and PSU model that would be great. Only professional equipment can test a PSU voltage.

With a desktop pc and power supply
You can use a volt meter (multi meter) on dc range probbably 20 volt range

Find a spare molex connector it has red black black yellow wires
Red black should be 5.0v and yellow black 12 v. Tolerance 5%

Or go into bios (uefi) and look at voltage, temperature and fan speed page
This will be under light load

Using a multi or volt meter you can check voltage when running a heavy load on pc

Most people don't own volt meters.

 

[bignastyid]

Those are obviously wrong, they system would not run if those were accurate. If you dont have a multi-meter you can usually pickup a cheap one at hardware shop, or even a place like walmart. Here's a pinout diagram if you want to try the multi-meter.

If you post the make and model of the PSU we might be able to tell you more.

If you are getting BSOD and sudden shutdowns, something is not right. A good chance it is your PSU. As said, the voltage readings that are being reported are wrong. If your PSU fails, it "could" take out other components with it. So you are putting your computer at risk while you save up for a QUALITY PSU. (You didn't post the make and model of the PSU, so we are assuming it is a low quality one).

Your system wouldn't run if those were actual readings , download HWINFO , check readings under sensor tab.

 

[turkey3_scratch]

TR2 is poor quality.

I get incorrect voltage readings using CPUID Hardware Monitor software on an AMD rig, so maybe it's an AMD "thing".

 

[turkey3_scratch]

Even HWinfo cannot be trusted necessarily, they are all inaccurate.

 

[Dark Lord of Tech]

It's AMD and HWMonitor.

HWMonitor is worthless.

 

[Dark Lord of Tech]

HWINFO is better software , but with AMD BIOS is your best option.

Thank you but I've already done that. Just forgot to tell. 5v is Ok in the HWinfo but 12v does not appear at all.

Hey people

Can it be my memory slots? I've changed those two memory sticks from slot #1 & #2 to slots #3 & #4 and my PC is on 3 hours straight without BSOD or Shutdown.

I'll try some stress tests to see what happens...

 

[turkey3_scratch]

Running a memory test is a good idea.

 

[Aeglos]

Folks,

I've bought a multimeter and run a voltage test in every single one of my PSU connectors.

12v => 12,53/12,54
-12v => -12,59
5v => 5,03/5,04
3,3v => 3,37
-3,3v => -3,37
stand by => 5,12v

Still gotta run some memory tests.... I've run windows mem test with 0 problems but I don't trust the results.

I've run MEMTEST and I get shutdown every time under the 2 minutes mark. I tried swap sticks, place stick in other slots, put only one at a time.... every time under the 2 minutes it crashes..... full crash. No BSOD, no shutdown+restart. Only full shutdown

Maybe it's the motherboard.

Plug the multimeter in and keep an eye on it while running memtest and see what it does. But it sounds like it could be ram, mobo, or the memory controller. Try running memtest with only 1 stick installed and do this for both sticks.

I've already tried with only one stick, for both. Tried put in slots #1 and #3. Same result. Shutdown under 2 minutes.

How hot is the cpu at idle and under load?

 

[mbarnes86]

Hi

Which memtest program are you runing?
First was memtest86
Then memtest86+
Finally memtest86 project restarted

Both recent versions support uefi bios

Or one on windows dvd?

How hot is the cpu at idle and under load?

45 celsius idle
75-78 celsiu load

(i live in Rio, and Its 30-35 celsius these days só Its normal to get these idle temperature)

 

[bignastyid]

Load temps are high. I think the max temp for the X3 is 73°C so it's possible you are seeing a thermal shutdown. What cpu cooler are you using?

I can't remember but the shutdown sometimes happen without considerable load or High temperature. Sometimes with 53 celsius.

 

[turkey3_scratch]

53C isn't high. So that wouldn't be a shut down from that.
