Just make sure you configure it so it doesn't hibernate.

I feel in order to solve the Yes/No/Maybe dilemma the 'plug 'n pray' approach is answer... 'There is no substitute for the definate answers provided by smoking equipment.' <comment>"No, it does not work" couldn't and shouldn't find any more a definitive backing for that answer than from a blend of: the distinctive smell of burnt-silicon spiced with the aroma of molten-copper... Yeah, I'll drink to that as far as definitive "No" answers go, but I hope what you get is that other flavor, "Yes, it does work" also a definitive one: the sight and sound of hardware silently buzzing as they sing the non-verbal equivalent of the Led Zeppelin song, "Rock and Roll"**  Notes: **From doubt (Yes/No/Maybe) to a Yes is, in a manner -- expressed in the lyrics, "(It's) been a long time since we rock and roll". </comment> ; |

Thank you all. Update:
Well, The jury is still out. With the GPU card installed, (sans smoke) and the motherboard BIOS set to 'use onboard VGA first' , we boot, of course to the onboard VGA as nature intended. With no GPU work units to crunch, there is of course, no GPU crunching of work units. There is a tad more noise as the GTX has two more fans. Moreover, the smart temperature monitoring (me) detects an aroma of hot capacitors from the power supply, and the PSU fan speeds are jacked up to 100%. 800 watts of juice and 4 x 120mm fans barely seems enough for 8 CPU cores and 384 CUDAS at 100 %. Boy, these CUDAS sure like their 32 amp power leads. With the computer now booting onto the GTX card with a monitor attached, Nvidia settings are happy and xorg.conf is updated, we draw enough power to run a small town, but still have no WU's to crunch, GPU-ingly. I have set WCG prefs to deliver unto me such WU's as may arise. I fear this is where we rest: waiting, like 500,000 other crunchers, for WCG CUDA(?) work units to arrive, poised with our hi-tech room heaters belting out the watts, and our house-plants wilting under the tropical heat. Until then, the question 'Do we (I) need a monitor attached to crunch GPU units uunder Ubuntu 11.4?' seems unanswered. I like the GTX 560Ti card. It comes in a box worthy of a Fabergé egg, and is itself pretty beyond measure. This is no reason for buying one, however. . |

I remotely operate a PC with either one, two or sometimes three Nvidia cards in it under Win7 64-bit, and have not needed either a monitor or "dummy plug" (just a VGA plug with 75 ohm resistors to simulate the monitor load) for over a year now. That requirement was eliminated by a driver update from Nvidia, though I don't remember which version. It is probably the same with Ubuntu, thought I don't really know. But you no longer get smoke these days. It is no fun at all. You DO need to plug in a monitor, or dummy plug, to each gpu, except the one built into the motherboard, at least for the AMD gpu's anyway, at least thru version 11.9 of the drivers. Mikey...are you sure this isn't only for multiple AMD/ATI cards? I have a 4350 (yes I know old) that has ran for quite a long time (Collatz, Moo, PrimeGrid) with no monitor plugged into it. It is now in its third machine. (I have upgraded the others.) However mine is a single card machine not multi. It never had monitors plugged in once the system was built. I just login using remote desktop software. YES that is what I mean, MULIPLE gpu's, not counting the onboard one, NEED the dummy plug. I too have several pc's crunching just fine with ONE gpu in them and no dummy plug. Windows used to have a problem where it would not use the 2nd, or more, gpu if there was no monitor connected to them.   |

It comes in a box worthy of a Fabergé egg, and is itself pretty beyond measure. This is no reason for buying one, however. . Go into Boinc and attach to a new project like DistrRTgen and then say NO you do NOT want to crunch their cpu units and you will then know if you have your system setup to crunch WCG gpu units when they come along. There are several other Boinc Projects that can use your gpu too, just be mindful that some are better for AMD cards and some are better for Nvidia cards. Your 560Ti will LOVE DistrRTgen!! I was getting almost 250k credits PER DAY when I was attached there with my 560Ti. AND as long as you stay attached to WCG too you will get any available gpu units as they become available. |

Thank you Mikey. A day of testing and cussing has gone by. Here is the news:
Attached to GPUgrid. We can crunch on the GPU! Yay! Except Ubuntu needs a monitor attached, with every combination of Nvida/xorg/cc_conf fresh drivers/ onboard GPU at boot or not. No monitor at boot, the card does not exist to BOINC. No worries. To crunch, or not to crunch, that is the question. 'Tis better to crunch, than to cuss. So a monitor is attached. Test II : swap out boot drive for a Windows 7 drive. Reset BIOS and retest. Same thing. My Gigabyte mobo and the GTX won't BOINC without a monitor attached. O fickle computer! So! On a positive note; I can now GPU crunch, and keep my room very warm at the same time. I have also today trained the machine to run overnight on off-peak low-tariff juice, thus saving some for you guys and keeping the place toasty for breakfast time. Thanks to everyone for suggestions. S. |

Lock for a vga dummy on google then no monitor is needed.

Boy, these CUDAS sure like their 32 amp power leads. I have no trouble running a GTX 560 Ti and an Ivy Bridge i5-3550 (4 cores) on a Z77 motherboard, with a Seasonic 330 watt power supply. The most that it has ever drawn is about 220 watts from the AC plug when running all the CPU cores on WGC, and running Folding@home on the GTX 560 Ti. With your i7-2600K, and if you do games, it might draw somewhat more, but I think that there is something wrong with your setup. You should not have any power supply problems at all. (I enable the internal graphics too, but don't have any monitors or dummy plugs connected at all. I manage it remotely over the LAN, but that is with Win7 64-bit.) |
