Proj. 14157 WU Failed: clEnqueueReadBuffer (-5)

[gordonbb]

Hello,

I noticed my points were down a bit today and discovered that I had a failed WU on one of my systems that has been otherwise stable.

Hardware is a EVGA GTX 1060 6GB "Shortboard" running in a PCIe2 x16 slot in a Acer ITX motherboard with 3GB DDR3 and a dedicated AMD Athlon II x2 220 2.8GHz processor.

OS is Ubuntu 18.04.1 LTS Server. Nvidia Driver is 415.27 from the ppa repository

The GPU was at 67C at the time, Shader Clock was 1999MHz, Power Limit set to 110W, +78MHz Shader Clock Offset (OverClock) which has been stable for months.

I had rebuilt the OS from scratch a few weeks ago.

The WU was successfully processed by the next folder to be assigned it.

Whether that means your card was the problem or something else, not easy to determine.

Thanks Joe, This thread about “clEnqueueReadBuffer” referenced an issue in the 375 drivers but in those cases the GPU consistently failed to fold whereas in this case my system immediately picked up another WU and completed it and has kept on folding since completing 5 WUs so far without issue.

A later add-on in the same post implied that it might be a hardware issue and mentioned spurious “Bad State” errors which I’m not seeing but I do see the occasional Bada Topology Warning.

The motherboard and CPU are 10 years old but have been OK folding for the past nine months and the GPU is less than a year old.

The system is on a UPS, but it is a APC Single-Conversion BackUPS 1000VA rather than an Eaton Dual-Conversion UPS like my two other rigs so it is possible that the UPS has a battery issue which would cause it to bypass the UPS and not filter transients. Though this UPS has my FreeNAS server as well as My ESIx Server on it both of which are operating without issue.

I’ve dialled back the GPU Shader Clock offset one bin to +65MHz and will keep monitoring it. The card has a little more than two years warranty left so I can get it replaced if necessary by EVGA.

On Windows, this is usually caused by a driver reset after something went wrong on the GPU ... usually, reducing overclocking solves the issue ...

On Windows, this is usually caused by a driver reset after something went wrong on the GPU ... usually, reducing overclocking solves the issue ...

FAH"s official position is that "we don't support overclocking" Unfortunately not all WUs are equally tolerant of overclocking so I'd bet that you just hit one that was inconsistent with your previous benchmarking. The (-5) is an out-of-resources error ... which may simply be that the GPU was off-line briefly while it was being reset.
