I run a Gigabyte GeForce GTX 590 and want to add a second one. Can it be a different brand, such as EVGA, and use the gigabyte driver with no problems? And do I have to use a dummy DVI plug? Thanks |

Unless the driver you are using has vendor specific descriptors in the inf any manufactures nvidia card should be OK. EDIT: The bundeled software that came with your Gigabyte card may not work with other manufactures cards. So you might want to go with 3rd party software for overclocking & monitoring. BOINC & SETI@Home use each card, more or less, independently. So you should not need to worry about mixing brands or models of the same generation. If you are planning to use the cards together via SLI for games or graphics software that is a separate matter. I think you still want to disable SLI for BOINCing. AFAIK dummy plugs have not been required for a while, but I have not kept up on that.

I run a Gigabyte GeForce GTX 590 and want to add a second one. Do it, but disable SLI. Download the driver from Nvidia directly, and you will be ok. No dummy plug is necessary. Newer drivers don’t need them. Tim |

Thanks for the replies. Will be doing some gaming but no SLI. Currently running driver 306.97 I'm in the nvidia control panel but can't see where to disable SLI ? |

Thanks for the replies. If you don't have the SLI jumper in place between the 2 cards you don't need to worry. Without the jumper, SLI is not enabled to begin with. T.A. |

I've recently installed a second GTX 670 in host 6910484: prior to that, I had no way of testing SLI. To start with, I had two independent cards, with a monitor plugged into one, and nothing at all plugged into the other. Both cards crunched independently. Then I found the SLI strap I'd lost, and connected it (with power off, I hasten to add). The driver control panel (114.07) came up showing an SLI option, and said it was disabled. Both cards crunched independently. I've just been down and enabled SLI, with BOINC running but no GPU tasks active. The screen went black, and the GPU manufacturer's hardware monitoring tool died (it restarted OK) - and BOINC soldiered on as if nothing had happened. I re-enabled my normal quota of BOINC GPU tasks - two SETI on device 0, one GPUGrid on device 1. Both cards are crunching independently. Conclusion - modern drivers can handle SLI automatically too, just as they don't need dummy monitor plugs. Your settings don't matter. |

Ok I have installed the second 590.... I can only mount them back to back so I'm asking about cooling. There is only about 1cm between the cards. Is this enough room for airflow etc.... are these cards designed to be that close and still cool ok? My case is a Lian-Li X1000B with 5 fans - 3 in & 2 out. Thanks |

Not good ideia, GTX590 produces a lot of heat, rise the fan speed and keep an eye with EVGA precision, if the temperature rises about mid 80 C slow down the clock. Try to keep the GPUs far as possible, 1cm is to close the air can´t flow without some external help. The use of some aditional fans to take out all the hot air you could it´s a god ideia. I keep my 590 in a 590/690 host below 82C with 2 WU running at a time on each 1/2 GPU with the use of few external, direct mounted above fans. And don´t forget the front exaust, manage the air to avoid the HDD or other devices. |

Both cards are running but there is a problem. Seti shows my first card as device 0 and device 1 - it was like this before I added the second card. But the second card is only shown as device 3, device 4 is not there. The second card is only using 1 of its 2 GPU's.... can anyone help with this? Not good ideia, GTX590 produces a lot of heat, rise the fan speed and keep an eye with EVGA precision, if the temperature rises about mid 80 C slow down the clock. With one card my GPU temps were 78 to 80 degrees (stock), if I can get my second card running I'll see how having 2 cards close together changes the temps. |

Both cards are running but there is a problem. Is the second card new or used? My initial thought is one of the two processors on the card is dead. EDIT: As you can see here , BOINC is only seeing three GPU cores. What PSU are you using for this system? |
David Steel Send message Joined: 12 Jul 01 Posts: 52 Credit: 17,713,386 RAC: 0 |
I have tried both cards one at a time, they work fine as device 0 and device 1 so there is no dead GPU. As soon as I add the second card it only shows as device 3. My PSU is a Corsair HX1000w, plenty of power I think. |

1000W is at the limit ( or above the limit ) for 2 GTX 590 and the system. Also update to 7.0.28 version. 6.10.58 doesn’t know ‘’what’’ is a GTX 590. Tim |

I have tried both cards one at a time, they work fine as device 0 and device 1 so there is no dead GPU. As Tim suggested, try upgrading your BOINC version. I'm running 6.12.34 on my twin 590 rig with no problems. 1000W is NOT enough for 2 590's and everything else. 590's have a rated draw of 600W per card, 2 cards = 1200W, plus the rest of your hardware. In fact, Nvidia lists it at 700W minimum system PSU for one card. My twin 590 rig has 2 PSU's: a 1200W for the 590's and a 650W for everything else. |

I don't think it's that high? The geforce website says: Maximum Graphics Card Power = 365W With boinc not running my MSI afterburner only shows device 1,2 & 3 so it might not be a boinc problem.... |

I agree with Gate´s, 1000W PSU is below the limit, it´could work, but for how long time? Specialy if you going to crunch 24/7. The specs could say 365W but all electric system have looses, so you should imagine no less than 500W per GPU is the real minimum + 300W for the rest of the system, so a 1350 or more PSU is the minimum. I use a 1450 W in my 590/690 host. If MSI not show the GPU must be a instalation problem, if you go to the Nvidia control pannel it shows the 4 GPU´s or 3? What shows by the windows devices? My guess is the second card was not recognized by windows during the instalation process, so Boinc or MSI Afterburner can´t use it, maybe a clean reinstalation of the driver/device could fix that. If the windows recognizes the GPU´s did you try to add the <use_all_gpus>1</use_all_gpus> to your cc_config file? Even if you have 2 exactly the same GPU´s the Boinc uses only the fastest one by defoult. As you say, each GPU is working alone so i imagine is a simple configuration problem not a hardware failure, even if you use a limited PSU the windows must first recognize the GPU in order to use it. One last thing, you are ussing stock aps, after you fix the problem, try to use the x41zc from Jason´s site http://jgopt.org you will fill the diference in performance. |

Well I got it going without really doing anything.... Pulled them both out, swapped slots, rebooted and now device 0, 1, 2 and 3 shows in Boinc and Afterburner shows GPU 1 to 4. I will have to change my motherboard so I can space them further apart. Running them back to back on this MB they are getting too hot. The bottom card stays at about 78-80 degrees but the top card hit 96 degrees. It's just sucking in all the heat from the card 1cm below it. BTW I think 1000w PSU is fine for 2 x 590, Guru3D did a 590 SLI review and the system wattage with the GPU's in full stress was 890w, and that was with an overclocked core i7 965. http://www.guru3d.com/articles_pages/geforce_gtx_590_sli_review,3.html Any motherboard suggestions where I can space 2 x 590's as far apart as possible? |

Well I got it going without really doing anything.... As far apart as possible? Build another rig. Not joking, really. Another modestly built rig will support the second 590 better, and afford it a good home. I just a couple of days ago lost the 590 I had. Toast. Had a 560 running directly beneath it. Fans full bore, but with two cards that close together, hard to keep temps in check. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Well I got it going without really doing anything.... If you check more carefully, guru3d say that you need 700W for 1 GTX590, and 1000+ for 2. SLI or not. You will have random restarts, and your computer will freeze at some point. ( hope not ). Check this one: http://s1343.beta.photobucket.com/user/Timol1/media/DSC_1920.jpg.html? I added one more 1200 power suply to support it.Now i have 2X1200 for the 4 cards, and one 1000W just for the system. ( not in foto yet ). Tim |

Pulled them both out, swapped slots, rebooted and now device 0, 1, 2 and 3 shows in Boinc and Afterburner shows GPU 1 to 4. When you do that the windows reinstall your boards, so it automaticaly fix you problem. As i say before "maybe a clean reinstalation of the driver/device could fix that". If you check more carefully, guru3d say that you need 700W for 1 GTX590, and 1000+ for 2. SLI or not. 1KW could work, but the question remains... for how long? As Tim explain, follow the experiences of who have some, go for a single rail gold or platinum PSU with >1k2W if you don´t like headaches. 80C is OK for the 590, high 80 or 90 NOT, don´t use the GPU under this high temperatures. You could try to slow down the clock, open the case and put a house fan direct above the GPU´s until you get a better solution. You ask for a MB, there are few good options but you need to show a price tag (MB goes from few 100 to 1000! US$), i allways use ASUS or EVGA MB and Intel CPU´s, but AMD CPUs are cheap and works OK for crunching. Something like this will give you a good ventilation a have the power to drive the 2 x 690 at full capacity: http://www.evga.com/Products/Product.aspx?pn=132-SE-E775-K2 http://usa.asus.com/Motherboards/Intel_Socket_1155/SABERTOOTH_Z77/ or http://usa.asus.com/Motherboards/Intel_Socket_2011/P9X79_PRO/ |

There are MBs that have > 2 PCIex16 slots, each spaced for double wide cards. So if you used the (say) first and third slots your cards will be spaced far enough apart to afford better cooling for the top card. For an older AMD board, for example, look at the ASUS Crosshair II Formula; there are many examples of similar Intel and AMD boards. They are not too expensive, if you don't look at top-of-the-line gaming boards. And don't worry too much about how many lanes go to each slot, as you are not doing much in the way of data transfer when running SETI. |
