Regarding those that are struggling for WUs... I have two boxes that are only on for 12-15 hrs a day that haven't been out of work for over a month when I set them up, compared to a couple of others that are on 24/7 that are struggling to keep the 'hoppers full'. I can't understand the logic - some machines just seem to go through rough patches. |

Windows upgrade question....

I much prefer clean installs rather than upgrades which in my experience often turn out to be buggy or run less efficiently. |

Just press and hold the power button for a few seconds will generally force the system to power down, even if frozen. |

Tansferring WU to new machine?
(Message 1133068)
Posted 665 days ago by BMH
What's the best way, very specifically, to transfer un-crunched WU from one machine to another? I used to do this, not to cheat but because machine "A" (at work) had internet access and machine "B" (at home) didn't. I never realised it was considered cheating or that anyone was looking at the performance of machine "A". |

One thing to try is, remove the mains power lead, remove the battery and then remove the CMOS battery for a minute. If that works then you'll need to enter the BIOS and set the date/time and maybe a couple of other things. If that doesn't work it may be faulty RAM or a fried CPU. With the first you can try one module at a time if there are two, as a process of elimination. |

Question: about Imac
(Message 1132270)
Posted 667 days ago by BMH
yes it is the monitors. Imac has a different setup in pixels...don`t remember what it is , but my professor explained it to me because I brought the subject up to him also. Possibly a higher dpi and more accurate colour representation by default? Especially with the latter compared to all the PC screen variations. Not to say it's not possible to have a PC with good visuals, but you have to choose your components wisely and maybe do some calibration if such things are important to you. |

credits and workunits: a fair system needed for Boinc
(Message 1132262)
Posted 667 days ago by BMH
I've been a SETI@home participant since '99 but I did stray away for a while while I participated in a non-BOINC-based project. I recently directed my computers back to the SETI because of an issue I had with the points system with the other project which I felt was not beneficial to the science. For me I enjoy setting myself little targets and comparing participants and computers with similar RAC. I like how we can all offer tips and advice and help out when people run into problems, while at the same time essentially competing against each other. |

SNMP Monitoring of GPU?

How remote are you? GPU-Z has a 'log to file' option - you can set it to log to a shared directory. |

Just wondering, can you be your own wingman if you have more than one computer? I guess it's not really optional but more theoretically possible? |

I just sent my original SETI cruncher off to be recycled :( An AMD K6-2 368Mhz with 128MB RAM and a huge 10GB hard drive. Still in full working order but just taking up space. |

With Internet Explorer you can reset the browser which should set it back to its default state (without the Google thing). Also, you can uninstall IE9 which should roll it back to the previous version which may also get rid of your gremlin. Then upgrade back to IE9. I feel your annoyance. Any software tool like this that installs itself without your permission falls into the virus category in my books. And I agree with the comments about Google getting a bit too big for its boots. |

I'm here. I cut back on my SETIing a while back but recently I've been getting back into the swing of things and building my RAC up to a personal all-time-high :D |

GTX 560ti Users: Information Needed
(Message 1129159)
Posted 675 days ago by BMH
I have a Xenta 800W 80plus PSU powering two 560Ti's in a Core i5 rig (only 1 hard drive and 1 optical drive and 3 fans). No problems. I wasn't sure about the brand but it's coping well - I normally go for a brand I recognise (Antec/Corstair for example) and certainly something that's 80plus rated, but this was a good price. I've used two PSUs to power multiple GPUs in the past. I made a 20pin 2-way motherboard lead so both PSUs switch on and off together. But again, you still need PSUs you can trust and that provide enough Amps on the 12v rail(s). |

Hyper Threading question
(Message 1128712)
Posted 676 days ago by BMH
A couple of months after I got my Westmere system up and running, I started this thread over at Einstein, which has quite a lot of data on this topic, not only my own but from others. Thanks for the link archae86, I found that an interesting read. CPU-Z indicates this CPU capable of SSE 1,2 and 3. The lunatics installer offers SSE3 and SSSE3 apps. Which one is better? As Sten-Arne said, you have to go with SSE3. SSSE3 is a newer instruction set, I presume that means better but I guess it just allows for specific tasks that make use of that instruction set when the CPU supports it. http://en.wikipedia.org/wiki/SSE3 http://en.wikipedia.org/wiki/SSSE3 |

Hyper Threading question
(Message 1128689)
Posted 676 days ago by BMH
I have a P4-based system with HT enabled. Because the system has a GPU crunching I specify in BOINC to only crunch on half the CPU (as I do with all my dual-core CPUs). However if this is half the P4's total performance, this is not going to be the same as using all of the physical core and leaving the hyper threading bit to supply the GPU. I see with my Core i5 (which has 2 physical cores but 4 threads) that if I tell BOINC to only cruch on 50% of the CPU, it crunches at 25% on each of the 4 'processors' according to the Windows Task Manager. I wonder if this would be as efficient as being able to specify that BOINC can use only the two physical cores and to leave the two remaining virtual cores free, or indeed if this is already possible? |

... the HD5830 just up and died on me today. Other than the fan is not spinning on it at all, so might be fan controller. I've had a fan controller fail on an Nvidia card fail in the past... all of a sudden the card let out a loud squeal as it overheated - I didn't know what the noise was but luckily my initial reaction was to pull the plug on the computer before investigating further where I descovered the GPU's heatsink was rather toasty. I resorted to connecting the GPU's fan to a motherboard fan header and all was well again. I was suprised the card survived - I guess it was lucky I was there to pull the plug on it. Sorry for going off topic... I suppose I should add that my main rig with 2 x GTX 560ti's is working fine :) |

Hyper Threading question
(Message 1128673)
Posted 676 days ago by BMH
"Hyper-threading works by duplicating certain sections of the processor—those that store the architectural state—but not duplicating the main execution resources. This allows a hyper-threading processor to appear as two "logical" processors to the host operating system, allowing the operating system to schedule two threads or processes simultaneously. When execution resources would not be used by the current task in a processor without hyper-threading, and especially when the processor is stalled, a hyper-threading equipped processor can use those execution resources to execute another scheduled task." http://en.wikipedia.org/wiki/Hyper-threading Performance-wise, I think Hyper Threading just adds a bit of head-room above a single-core processor, but it's not the same as a CPU with two physical cores. Even some modern CPUs have something similar. Take the new Intel Core i7 2600K for example, it has four physical cores but can handle eight threads. |

1. (6066962) Intel Core i5 CPU 650 system with Xenta 800W 80plus PSU, PALIT 560Ti SONIC 1GB, MSI 560Ti TWIN FROZR II 1GB, nvidia 270.61 drivers, 4GB Dual Channel DDR3 1333 RAM. Windows 7 Home Premium 64-bit SP1. 2. v0.38 3. I caused the downclock issue on one of my GPUs when I attempted to overclock it, I set it back to default clock settings, restarted and all has been ok again since. I have had 9 errors vs. 900+ valids since starting at the beginning of the month. 4. GPUs are currently at 80'c and 70'c although temps have been up 7 degrees on this. 5. Factory shipped frequencies: 900, 2098, 1800 @ 1.0380V and 882, 2098, 1765 @ 1.0250V according to GPU-Z 6. It's set to adaptive 7. As of yesterday yes |
