A problem here a short while ago.

Got this message a short while ago from AI Suite II, which is the monitoring software for the ASUS motherboard, including temperature.

Used to the warning messages about the temperature, this time I rather got a warning message about a 0.576 V overcharge on the 12 V on the motherboard.

For now I suspended the genefer_524288 CUDA task at 95.872 % completed.

Edit: Checking in with the monitoring software, it now is back at 11.904 V.

Should I pay more attention to this problem?

Any advice would be appreciated.

Thanks!

For a 12V line 11.9v is low, 13V is high. 12.5V isn't an issue. If it's not exactly 12V it's better to have 12.2V than only 11.8V.


EDIT- and any software that actually says "0.576V overcharge..." isn't worth having. It's over voltage.

Maybe true so, Grant.

Possibly this was the message being stated, but I rather was thinking of the possible problem.

Keeping a tab on the monitoring software, I finished the Genefer task.

Two more such tasks in progress in my task list, but for now I will rather get back to the Seti@home CUDA tasks for the rest of the night.

It could be a sign of the caps starting to wear out or the voltage regs over heating .The system should shut down if you have a big problem and 12 volt drops to 11.4 so untill then keep a eye on it to see weather the freqency of the alarm increases .

If it does your PSU or Caps on the MoBo could be ready to die

the voltage regulator can play up if over heated and so can the capacitors .

My 12 volt line run 11.95 volt 100% use

i've run it at 11.85 with different hardware

It's more important how stable it is , does it jump up and down in big amounts

12.1 then 11.9 back to 12.05 , 11.85 .........

It shouldn't move much more than 0.15 volt and not several times a second but once a second or two second's as normal operation.

Anyway, Glenn.

I think it may have been a temporary power spike since I do not see it again.

At times the system appears to be making an itching sound, as if wires are getting in contact with each other.

Thinking a little more about this and it could be the fan making this sound.

However, since things became slightly more difficult to handle, there is not much I can do about it for the moment.

Better let it run until something really happens.

yeh i agree don't sound like it's to much of a problem . Yes you are right too the power socket on the wall may not always be the right voltage and causes spikes .

The change in voltages, and you mentioned an "itching" sound.. I'm strongly leaning on worn/bad capacitors in the PSU.

My previous 600w PSU was one bought at a time when every review on Newegg said it would die in less than a month, and just over six years later, it was still going fine. Then it started to make the occasional ultra-high-frequency squealing sound and sometimes a static-like discharge sound. It startled me awake one night when it sounded like a firecracker went off, but there was no smell of fried electronics and the system continued to work just fine.

Then I started having random lock-ups and system hangs/freezes. BIOS said the 12v rail was sitting at 11.8, but I grabbed a multimeter and an unused connector and was actually only reading 11.3. I grabbed the 550w PSU out of the other machine (same story as the 600.. bought at the same time and it was "guaranteed" to fail within 30 days) which had been running 24/7 for six years, as well, and BIOS showed 12.1v and multimeter agreed. I put the 600 in the other machine since there was a lot less load in there, and it worked for a month or so and then just completely died. The 550 worked in the main machine until I got a new board, CPU, RAM and decided to get a new 750w PSU with good reviews.

That 550 is still running in the other machine now. I bought it in October 2006 during a really bad spell of poor quality control.. and it is still going. The 600 didn't fair so well. Once I got my main machine upgraded, I opened up the 600 and three caps had exploded, the other five had oozed everywhere, and one of the legs on a voltage regulator had gotten so hot that it melted itself (aluminum) at some point and was no longer in contact with the PCB.

Long story short: your PSU is on its way out. Plan to replace it before too long. Hopefully it doesn't take components out with it when it goes.

Cosmic your PSU can also have it's own circuits to cut power below 11.4 for a prolonged time . very's from PSU to PSU also type of socket and system 11.3 - 11.5 cut power

Thank you for that reply, Cosmic_Ocean.

Quite thorough answer, indeed.

Keeping a tab on it, +12 V now stands at 11.712 V, going slightly down from 11.904 V.

Right now I do not feel to uneasy about it, because except for waiting for the fan to turn up when powering the machine and needing accessing the BIOS and also getting too hot at times as well, it runs quite well otherwise.

As mentioned earlier, this machine could have been even better without the soldered plate between the power supply and the motherboard. For now the software and drivers for the Sound Blaster card has yet to be installed and the other graphics card lies on the shelf.

There is not room for both cards when the Sound Blaster card is mounted.

Whether or not I could redo this thing I am not sure I am able to do.

11.7v is not good the psu should be stable around 12.2 or so ...my psu drops from 12.2to 12.1 when seti fires up but that is 3 980's fiering up plus 12 cpu tasks but it comes back to 12.2 a second later

the asus software is complete junk don't even bother looking at that ...(i run a sabertooth board)

I came down with a bad case of i don't give a crap

Thanks!

The ATX specification states the tolerance for the 12v line is +/- 5%. So anything from 11.40v to 12.60v is within spec. In practice it seems like many PSU manufactures run closer to 1-2% on the 12v line.
How much of that variance your GPU can handle is a different question. I think it was the 550ti GPUs we found had a very low tolerance to 12v fluctuation.

Also consider that some monitoring software can go off sometimes. HWMonitor from the people that make CPUz sometimes tells me that my CPU fan is running 750,000 RPM.

that must be one hell of a fan

but siriously the asus software is buggy and broken don't use that junk

Thanks, HAL9000.

Possibly somewhat true, but for now I will have to use what I am having.

As usual, it becomes a choice between sometimes pushing things to far against using those tools which are supposed to remedy from such problems.

This means that you are not supposed to be pulling the plug when a keystroke for some reason do not work, or your mouse is not working.

Still, you could possibly be experiencing the fatal blow which means disaster without any warning.

Therefore it becomes a choice between several options, which could end up you perhaps being to lenient or relaxed, when you rather should be paying attention to what is happening.

Checking in with the monitoring software, when selecting "Sensor" from the Toolbar which is showing the options "Auto Tuning", next "Tools" through "Settings" and also the logo to the left as well as the minimize and close to the tray icons to the right, when doing this, only the tab for the option being selected is visible.

Here there should be a fix in order to display each option by means of a tab side by side.

Except for that, not too much to be complaining about.

Perhaps more is not needed to say.
