Problems Switching to GTX 570
(Message 26977)
Posted 4226 days ago by Jeremy The "clean install" option in the nVidia drivers is a misnomer. It's not nearly as clean as one would like to think. It only removes custom application profiles and driver settings, it doesn't actually uninstall the previous driver or any of the registry entries. To do a fully clean driver install: 1. Uninstall the nVidia drivers via the Control Panel. 2. Reboot 3. Run a driver cleaning program to remove any remnants. Treexy Driver Fusion (formerly known as Driver Sweeper) and the free version of Driver Cleaner Pro are both very good 4. Reboot again 5. Install new drivers 450 watts should be enough for that setup if the PS is actually capable of delivering that much. If the PS is a few years old, it might not be able to deliver to juice anymore. They do start to deliver less power as they age. Cheap power supplies in particular age poorly, and they don't start out that great to begin with. |

GTX 590 coming?
(Message 20715)
Posted 4781 days ago by Jeremy The dual GPU on a single card configurations have certain advantages. Ability to install in a single PCIe slot motherboard is one, but another (the one interests me, frankly) is water cooling. A single watercooling block is typically about $110-$120 or so. With proper cooling, there's little reason a dual-GF110 card won't be able to achieve full GTX580 clock speeds if your power supply can handle it. Once you factor in the costs of the waterblock(s), it might even be less expensive than two 570/580s. Time will tell, but I'm interested to see what nVidia actually brings to the table. |

Fermi
(Message 15496)
Posted 5165 days ago by Jeremy Disclaimer: I do not know as much about chip design as I'd like, and I'm holding off any commentary on Fermi until it's actually in reviewers' and end users' hands. Anything else is pure gossip and conjecture as far as I'm concerned. That said, much has been made about Intel's vs AMD's vs nVidia's design decisions. AMD vs Intel's approach in the CPU world intrigue me. For Intel, they were content to package two chips onto a single die to make their initial quad core offerings. It worked quite well. What prevents GPU makers from doing the same? Two GT200b(c?) dies on a single GPU package. It'd be a GTX295 that wouldn't require doubling up the vRAM. Make it at 40nm. It seems to make so much sense (at least to me), but nobody is doing it and there has to be a reason. Does anybody know what that reason is? |

Lot of computation errors on all CUDA apps
(Message 15119)
Posted 5182 days ago by Jeremy Just to clarify, that bug only affects software overclocks. If the overclock is burned into the BIOS the card won't be affected by that bug. |

Posted 5184 days ago by Jeremy Your CPU overclock is a bit aggressive. Does it pass Linpack/Intel Burn Test stress testing? I had issues with my overclock that only showed in GPU apps for some reason. Double check your system stability if the SLi switch doesn't do anything for you. You need to be able to run FurMark and Intel Burn Test at the same time for 10-15 minutes without errors in either. Errors may not show in games or other BOINC apps, but it'll show in the CUDA apps. I had to throw a little more voltage at my CPU to get the whole thing 100% stable. |

Posted 5190 days ago by Jeremy I see that a few people have them, and there's a check box to "Add my signature to this post", but I haven't been able to find the place where I set up what goes in the signature. Could somebody give me a click by click map? Thanks. :) |

New nvidia beta application
(Message 14902)
Posted 5191 days ago by Jeremy If you set Boinc to use 3 of the 4 CPUs, this actually applies to GPUGrid tasks as well. So Boinc will try to run three WCG CPU tasks, and use one of these CPUs for the GPU tasks, leaving one CPU free (useless). This is not the case based on my most recent experience. Last night I set BOINC to use 75% of available cores. Turned it loose and I got 100% load on 3 out of 4 cores and an average of about 30% on the fourth with no background tasks active. If I suspend activity on all projects except GPUgrid I get the same result. One core with a 30% load, the rest with nothing. That's with two 6.71 GPUgrid apps running. BOINC 6.10.18, Win7 Ult64, C2Q @ 3.83 GHz, and two GTX 260-216. I'm waiting for a few more WUs to finish before I check to see if there's a performance advantage to running this way. |

Slower GPUGRID processing in Windows 7
(Message 14802)
Posted 5194 days ago by Jeremy My blind guess is immature GPU drivers in Win7. I'm seeing various small issues with the display driver here and there, and have even had one or two BSODs which (strange but true) I never had under Vista. Something isn't optimized correctly and if I had to guess, I'd place my bet on the nVidia driver. |
