are these normal voltage readings? (cpuid)

[macey]

vin1= 2.028 to 2.028
+3.3v= 2.940 to 2.940
+5v =4.899 to 4.919
-12v =3.696 to -4.800 (constantly fluctuating)
-5v = -6.096 to -6.096
+5 vcch= 2.822 to 2.822
vbat= 1.620 to 1.620

I dont know why there is no negative 3.3 or positive 12

There's never a -3.3, and I couldn't tell you why you don't see a +12V. What is showing you these readings? BIOS readings are notoriously inaccurate.

 

[nukemaster]

HWmonitor does not always read accurately.

The 5 looks to be within spec. vbat should be about 3 volts give or take a bit.

I would honestly trust the bios before I would trust those readings.

Check it out . while some things are right. Vin1 is my memory.

 

[macey]

ok, no idea if my 12v- is any good then, yours seems to fluctuate a lot too though, thanks for showing it.
rather your12+ does

 

[nukemaster]

if any voltage was THAT far off(like your -12 shows. your -3.3 is also out of spec according to that reading), the system would not even be running.

For the hell of it, give the bios hardware monitoring or system health section a try to see what it shows.

I went into bios for 15 minutes, +12v was 12.024, vcc3 was 3.344 ddr15v was 1.524 vtt was 1.064
all were stable.. but no reading for a 5v ?!

Oh yeah also if i go into advanced voltage settings, it gives me a warning that ive experienced boot failures because of voltage changes or overclocking and that the last settings in the page may not coincide with current hw states. (i have never overclocked)

I pulled these figures from the system health place

 

[nukemaster]

The "experienced boot failures because of voltage changes or overclocking" is a generic message the bios gives you if you power off the system before it finishes posting as well.

So if you try to get into the bios and figure you missed the DEL key and just reset the system or power it down part way into the post, you can also get this message.

Did you by any chance do something like that?

As for 5 volts, you can check both 5 and 12 from a 4 pin molex connector with a multi meter.

Black to Yellow is 12
Black to red is 5
Black to orange is 3.3(no in a molex, I do not recommend metering the SATA cables because you can short them out easy)

While this gives you an idea, a meter does NOT show voltage ripple. so even with perfect looking voltage you may have massive ripple(but all quality power supplies deal with filtering very well).

 

[macey]

ok thanks. i dont think thres much else after that i can try withoutt aking to the reapir shop to be close enough to knowing whether its mobo or psu.

 

[nukemaster]

Well is your system stable? If it is, Chances are it is working fine.

If the 5 volt was out of spec, usb devices(bus powered) and ssd's or 2.5 inch drives would have issues too since they run right off the 5 volt rail.

vbat= 1.620 to 1.620 <=== That's just wrong

That's the coin cell battery that allows the CMOS to retain the system BIOS configuration. Those coin cells should be 3 Volts.

If CPUID HWMonitor or HWMonitorPro doesn't properly support the sensor chip on your motherboard you will end up with erroneous readings or missing PSU output rails.

Try using a better monitoring utility. Even the one that came with your motherboard would be more trustworthy than HWMonitor.

I've downloaded and used the freeware utility HWiNFO64 and used it on my own system because HWMonitor was just complete garbage.

This is what I see on my own system with these two utilities:

 

[macey]

Ah that program is great ! Yeah, all in normal parameters.
my sytem aint stable but im going to give up now, either the psu or mobo is screwy. gonna take to a repair shop

if my 560 is present in the system, just installing either integrated or any version of discrete gpu drivers makes the sytem unbootable. i have tried on multiple freshly formated hardrives before installing anything else too. Once I take out the 560, I have no porobelms installing integrated graphics.

My 6600 gt I can put in, install drivers and fuly stresstest, no problem, ... I rma'd the 560.. andd there is no fault with it!
Weird problem eh? Dont think there is any other way to diagnose it without lots of expensiove equipment. (I dont have a spare psu )

 

[nukemaster]

A spare power supply is the best way to test for that(along with a nice pile of spare parts.).
