This is possibly a good idea then there's a continuous stream of GPU-work, but atleast for now it makes little sence to sacrifice a CPU-core for the < 30 minutes of WCG-GPU-crunching per day. If he was just waiting for WCG GPU WUs I would agree but since he is testing at GPUGrid freeing the 1 core will make a big difference in how fast his GPU can process GPUGrid tasks.

Edit. Note that it says "Running(0.54CPUs+1.00 NVIDIA GPUs). Does that mean that it is using about half of one of my I7Cores and all of the processors in that NVIDIA GTX 580? (hopefully) It jumped the wattage used on that machine from about 160Watts to 335Watts. @RT Did you free up one of your CPU cores for the GPU to use? Set BOINC to use 87.5% of your cores (on a quad with HT) and that will leave 7 to crunch and 1 for the GPU. Will let the GPU work much faster since it's not competing with WCG WUs for CPU resources. Yes sir Ingleside. I read some place where Dataman had given that advice and so I took it by doing exactly what you both said. Thank You! I noticed where others are indicating not to do so unless you have a steady stream of GPU work. For the moment, I have that as I have an aparent giant WU from GPUGRID. (ACEMD2: GPU molecular Dynamics 6.16 (cuda31) runDIG1_r345-TONI_TAKEOTTO-15-100-RND8997........... I am thinking there must be a problem there as it has been running over 10 hours now and the total wattage has dropped from the 335 back to the 170s. Off to see what I can find out at GPUGRID. ---------------------------------------- [Edit 2 times, last edit by RT at Mar 15, 2012 1:30:25 PM] |

On an i7 2600 hyperthreaded (8 cores 100%) not overclocked and a NVIDIA GeForce GTX 560 default clock rates: 20 Beta HCC GPU average runtime: 4.83 minutes 5 Beta HCC CPU average runtime: 73.44 minutes So 1 GTX560 is 15times as fast as one i7-2600 thread. Basically twice as fast as the CPU. Good marker. Obviously this includes ~1/3rd CPU usage time for the GPU WU. The faster GPU's will always be limited by the CPU portion of the task; x CPU time + y GPU time = total time. PS. RT, sounds like your GPU is downclocking! |

I just went over to GPUGRID to see if someone could help. I cannot ask a question because I don't have enough credit.  OK....hum downclocking. That sounds reasonable but I have no idea why since it is getting a ton of cool air and has its own I7/870 core. I will poke around a bit...thanks for the tip. |

NVIDIA GPU 0: GeForce GTX 560 Ti 448 (driver version 29573, CUDA version 4020, compute capability 2.0, 1280MB, 1428 GFLOPS peak) Nvidia driver 295.73 has some serious problems and I would encourage you not to use it. One of the big issues is that if you have your monitor set to go into sleep mode your GPU will stop crunching and you may not be able to recover from sleep mode without a reboot. I would recommend 290.53 or lower until Nvidia fixes the problems. Oh I never us the Sleep mode on my pc's, ALL of mine are crunchers! I will go to an earlier one today, I AM having heat issues anyway and need to od something, the gpu is running at 99C and 100% fan!   |

I have an AMD 5870 in some other machines and it says: 3/14/2012 3:20:14 AM | | ATI GPU 0: ATI Radeon HD 5800 series (Cypress) (CAL version 1.4.1546, 1024MB, 2720 GFLOPS peak) So the same thing it is NOT capable!! Humm My 5870,5850, and 5830 all got Beta Wu's. Are you talking about the Drivers?   Yeah I seemed to have gotten it ALL wrong, a post a couple back says that even my 5770's will work! HMMMMM! |

That sounds reasonable but I have no idea why since it is getting a ton of cool air and has its own I7/870 core. I will poke around a bit...thanks for the tip. Again Thanks. I moved the card, reconnected everything and went back to 350 watts, the heat is apparent and the "Remaining" is dropping like a rock. That lasted about 5 min and now I am back where I was ... apparently downclocking. I need to poke around and find some diagnostics/monitoring software (surely some exists) so I can see if I can figure out what is going on in there. I sounds like heat but the card is getting plenty of clean cool air.  |

@RT. What driver version are you using? There are several good tools to monitor what's going on with your GPU. MSI Afterburner will tell you a lot and allow you to adjust your settings and save them as profiles. One thing that I have found that saves on heat and power usage with a very minimal effect on performance is to downclock the memory on the GPU. Afterburner will allow you to do that. I've downclocked mine by 50% which resulted in 25watts of power saving and 10c less heat. The process time stayed pretty much the same. I would also recommend you use a manual setting on the cooling fan speed. You can play with it to optimize the temps. Are we having fun yet?

I sounds like heat but the card is getting plenty of clean cool air. @RT: Sorry if I missed it but I scrolled back and cannot see this information; what is your GPU fan speed (%) and GPU Temp (C) when it backs off? I know you are getting cool air into the case but are you sure it has an unobstructed flow to the GPU fan. Sometimes wiring obstructions can cause air to move in strange ways and pool heat. What GPU monitor are you using? (GPU-Z, EVGA Precision, ?) (PS, I am astounded that GPUGrid will not help you. They were the ones that helped me get started in 2008.  )  |

(PS, I am astounded that GPUGrid will not help you. They were the ones that helped me get started in 2008.) Same thing happened to me DM. To cut down on spam their forum rules now require you to show returned results before you can post. Bummer when you're just trying to get started.
