You seem to have a lot of errors on that system.
Do they only occur when you reboot your computer? D
Do CPU tasks from other projects also fail?

Even in your finished WUs there are errors, but the simulation was able to recover. This hints at a serious hardware problem, which could be anything from the GPU to PSU, mainboard, RAM and CPU. I sorted these in dsecending probability.

Your "S4" is the Samsung phone, isn't it? As far as I know GPU-Grid doesn't support ARM CPUs, and very likely won't do so for quite some time to come, because they need fast hardware. In fact, only a handful of projects go through the hassle of building apps for ARM.

Well I have my GPU overclocked. Does OC increases the possibility of error during work?

Also, the S4 is indeed my phone. Samsung I9500 Galaxy S4 with Exynos cpu. I am aware of the hardware requirements for CUDA and OpenCL. I just made the question because the android based BOINC app has a GPUGRID project. I wanted to believe that it works on ARMs cpus (I think I might work on Tegra phones and tablets).

No other BOINC project have gave me errors on my systems, Intel-Nvidia desktop or AMD laptop.

Sounds like the OC is probably the issue. Could still be the card (physical), the PSU, or the motherboard.
