Crashes lately

[mezhaka]

I do see the

Code: Select all

FahCore returned an unknown error code which probably indicates that it crashed

for about last month. Is there any way to cope this?

Hello mezhaka, welcome to the forum.

There are more than one possible cause. Please post the ***System*** section of the log file, and then please describe the OS and HW config of this machine. Please also post a bit more more the log before and after the error, so we can see what the client was doing when this failed. Thanks.

I saw this when installed as a service. I un-installed and re-installed using normal configuration and it works perfectly now.

I am no sure what do you mean by ***System*** section, but hope this is it:

If you Refresh the log the system section including config can be seen by scrolling up to the top.

. . . or by clicking on the System Info tab in FAHControl.

[bollix47]

True but not easy to copy/paste and doesn't include the config section. At least I haven't found a way to copy/paste it on my setup. Otherwise, it is the easiest and fastest way to see how your system is being recognized by v7.

There have been very many experiences of this UNKNOWN_ENUM error when running 803x projects on NVIDIA GPUs. I have had many, on specific machines, but not on others, and not all the time - is it a sporadic error for you, or one that occurs always?

Things to check: that your PSU is giving the GPU enough power (these are very power-intensive units); that you have both display and CPU power saving options turned OFF; try running without folding on the CPU, or SMP set to 4 or 6, to test if that makes a difference.

If you look through the forum you will find many more suggestions. Some hold the view that it is the NVIDIA driver, and rolling back to 280.26 helps, but I have found that that doesn't make a difference. Good luck!

Concerning the power -- I have no idea how to check if it's "enough" power, i.e. how much is enough?

In general I am not that interested to investigate into this problem on my own. Last months my client stays idle.

I'm not sure how we can help you. Stasnford does not have technicians who will diagnose problems with your hardward. We can guess that you GPU is overclocked or more power is being used than can be provided by your power supply or the heat in the vicinity of the GPU is more than it's happy with, but without your active participation, all we can do is offer suggestions. When a GPU is unstable under load, the cause cannot be determined remotely without you giving us enough information to determine and fix the cause.
