Hi Just added SETI@HOME to my portfolio of projects that I participate in. Crunching only GPU tasks. After running it for a week, my stats look very weird to me. 50 pending validation - OK 69 validated - OK 59 validation inconclusive - ??? 27 validation failed - ??? 1 error - OK Basically more failed validations that successful! What can be the reason on such results? Running on W7, latest drivers installed for my Radeon 280X (17.3.3). Can anyone suggest a way to fix the problem? |

Normally when you have errors like that in those amounts, there's an overclock on the GPU that doesn't agree with the science applications. The tasks show that your GPU runs at a clock speed of 1070 Mhz, whereas 'normal' R9 280Xs run at 850 MHz with a boost of 1000 MHz. What you can try to do is install TriXX 3.0 (from Sapphire), or a similar package (like MSI Afterburner) and underclock the GPU speed. I like TriXX because it's non-intrusive, you can test things out before pressing Apply. |

Hi Thank you for your answer. That's the standard clocking of my MSI videocard. So I didn't overclock it personally. But I guess it might not matter. :) Do you think that I should recuce the memory clock as well? I'll try to set values to standard ones and see if it helps... |

Many people have found that even factory overclocked GPUs will produce errors when running SRTI@Home - this is because the operating stresses on the card are higher (the processing part of the card is running continuously at a very high level) compared to the normal (gamer) situation where the processing part is only running hard in short bursts.

Hi Yes, suggested solution did work. I lowered GPU/Memory frequencies to 1000/1500 and now I get only Validated results. Thank you all for the help. |
