X5000 just turned off

First time this has ever happened. Was working on the X5000 and for no reason at all it just shut down. I turned it back on and here we are as normal.

Really odd.

I do not think it was anything to do with anything overheating since it is cool here and the temperature dock is showing <60deg always.

Happened to me twice over the past four years. Exactly the same spontaneous switch-off.

Was not capturing serial output either so not sure if I could have caught something. I will pretend that nothing happened!

Had NAS mounted, Odyssey open, was working on linux machine through VNC. Funny enough it seemed like it happened at 1700 BST on the dot... but that is just speculation and probably coincidence.

It has become semi-regular for me. I was experiencing it every few minutes. Re-plugged the power cable to the motherboard and it largely solved the problem but after a day or so powered up, it will st switch itself off.

Sounds weird, I'd try getting a new PSU.

strange this must be an issue with X5000's as I've never had this happen with my X1000 since new & that's over a decade ago now..or maybe I'm just a lucky guy and there are also X1000 users that this is happening to?

@trixie

I thought about that, but am loathe to take such an expensive option, especially as i invested in such a good one when i built it.

@daveywQuote:
One possibility is that there is somewhere (cable/component/connector) an intermittent short circuit, activated e.g. by heat or a certain position of a cable. That would cause the PSU to cut-off power.

I had that problem for a while a many years ago.
It went away when I installed a new uboot.
So maybe there was a bad contact between the sd-card and the motherboard or maybe i needed to unplug and replug something else that had poor contact while installing the new card.
5 years later it is still running good 😎

Hey guys,

Well, this same thing just happened to my X5K... My machine
has been on for days/weeks and I had a bunch of things open
(AmIRC, IB, Codebench, etc) and at the moment was alternating
between AmigaAmp and YT vids in MPlayer... and the X5K just
shut off. First time ever. :/

I restarted it and more closely watched the temps with Javier's
X5000temp docky - the CPU started at 51C and went to around 52.
But "PCIe" started at 78C and rose to 79C. But then it locked
up starting another YT vid in MPlayer.

Any idea what exactly the PCIe temp is reflecting? Some chip
related to the bus? Would that reflect gfx card temp or more
then that?

I saw someone in the X5K Case Fans thread mention the acceptable
range for the CPU being 15-105C. Any ideas on PCIe?

More importantly, is this simply a sign I need to add to add
more fans to the case? Maybe my PSU is going (it's the one from
original build)?

I'll take sometime to reseat things, vacuum things out and see
how things go....

Let me know your thoughts.

Thanks,

PJS

It has never happened since my original post. If it does I will capture anything on serial since I have serial eternally running on my machines. But, I suspect if it ever did happen again I wouldn't see anything on serial. We will just have to see.

I just put it down to a solar flare.

I had this hapening to my X5000 twice a couple of years ago on a very hot summer.

The CPU in the X5000 can't overheat thanks to temp protection in the MCU,
that protection may be the cause of sudden switch off.

Clean out the dust in the CPU heatsink.
