Hey folks i just went back to use my iGPU to crunsh for seti, sofar so good. Then i thought, is that all ? I mean always said you can`t overlock a Celeron G1820 cpu, but what´s about graphics ? So i overclocked easaly my graphcis core +150 Mhz , temps at 50°C. You could do that too, but it´s always dangerous to you cpu, i just want to remind you about this before. https://downloadcenter.intel.com/de/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU- It´s from Intel and easy to use, cross your fingers if u clock.

With Intel's APU devices always worth to check total device throughput, not just GPU or CPU parts. The reason - they very strongly interrelated. Crunching on iGPU can decrease CPU part output in big degree. And vice versa. So, check your device output being CPU-nly, then with iGPU enabled (and/or overclocked). Quite possibly best throughput will be achieved for smth between idle CPU cores and full-loaded cores+iGPU... SETI apps news We're not gonna fight them. We're gonna transcend them. |

ok, i will post the results later, hope there is a minimum of 10% gain. |

As i see, my i5-Ivy Bridge cpu can´t be clocked, dam... |

ok, i raised to 1,250 Mhz , also applied Lunarics for cuda5.0 (broken GT640). I´ll hate to waste time. |

http://setiathome.berkeley.edu/result.php?resultid=5049777045 ok, 2hours 6minutes (clocked with 1250Mhz), too much for a improovment ? don´t tell me i have run at stock too see a result, it´s late today. |

5,000 seconds for ewhat ? 54 points naw not anymore, i´ll close all intelgpu workunits. |

Is there any project (active) that have short worthy nice plesant workunits to crunsh ? First of all i search on WCG. |

Nothing found on WCG, but on Collatz , slow on crunching but points. |

3 days running, no issues only when i overlocked too much...clocked at 1250Mhz. |
