And another thing, I was able to get linux on the SUPER32 machine with the NVIDIA driver from additional drivers but the application seems to be failing and I have no idea why. I have never used Linux this much. The program screen would fade dark and then freeze up... If you unzip over the old folder, you might help and you won't lose your current tasks and parameter files.

Weird, I seem to have fallen off the leaderboard altogether even though my score is going up. What the heck man?? |

Funny, I just sold an old AMD FX CPU I was using to run two GPU's. The Dell Core Duo farm I have only has one PCI slot AND I have to do some cutting of the air duct to get em in there but hey, they dont burn so much juice. Been paying for it 24/7 just to see what I can get er up to. Dave |

Perhaps. Its much easier just to throw a bunch of PC's at the problem and I have a garage full of them. Welcome to the "Farm". :) We have "several" people who have a large number of systems. Some are pretty high end. Others are just having a lot of 30,000 to 50,000+ RAC boxes giving them very impressive individual totals. With that many gtx 1060's running on almost any CPU with Linux/CUDA91 you should see some pretty high group volumes.

I just went through major problems trying to get the Gigabyte board to run the full 12 cards. It took a while to get it to even see all 12 cards, then it ran for about 5 minutes and started producing numerous errors. It seems it just doesn't want to run with my choice of 12 cards. Trying to go back to just 11 proved troublesome too. It would run for about 10 minutes and start with the errors again. Finally, I ended up rearranging all the power connections and finally got it to run on 11. It seems it's really picky about the power arrangements. You might try rearranging a few yourself, and don't try to run all 13 cards. It sounds like this kind of setup is both brittle and fragile but once you have something working, it will run, and run and run :) Tom "I owe", "I owe", "Its off to work I go" (from a bumper sticker on a smallish Mercedes Benz) (on the back of a Semi Tractor) "If you can read this bumper sticker, I've LOST MY TRAILER!" |

The miner is unstable enough for me to get a bunch of PC's running Linux with two cards each. I've put a lot of time in the miner and I'm not happy with its stability. Its a pain in the alien. May the force be with you... |

Yes, that compares to what Ian&SteveC and I are both getting with two gtx 1060's on dual e5-26xx systems. You can get a little faster by using the -nobs command in the app_info.xml file and I am now trying the -unroll 6 command because the docs say that is what it should be, even though autotune appears to be doing that already. It probably won't make a difference. There is an "overclock" e5-2670 Youtube video out there that actually was created using my ASRock MB :) I didn't seem to see any differences when I first tried it. It is still on my "last straw" list to eak out a little more RAC.

I have a bigger problem to deal with right now. I am cloning the HD that has the working copy of the Linux system for the Xeon E5 system to two others just like it. I need to change the machine names of the other two in Linux but dont know how. Any help? Thanks. |

Ian&Steve C. Thanks for the wisdom! Duh, newbie mistakes. mining mode is still on. I will dig deeper into the bios later. I finally have one Xeon E5 up and running with two 1060 GPU's! Yahoo! ~2min work units sound good? I take it on that system its okay to let it run the cores/threads as it has plenty of RAM?? Doesnt seem to impact the CUDA units... |

I know i'm late to this party. but there were a couple things of note i should add. 1. it doesnt matter to the OP now that he's moved to Linux, but it was mentioned before that you can't run an application at startup with a windows 10 PC that has a password. this is incorrect. you just need to configure auto-login (with password) so that you dont get hung at the login screen. from the start menu -> Run -> type in "netplwiz" and follow the instructions here: https://www.digitalcitizen.life/log-automatically-windows-7-without-typing-your-password. simply uncheck the box for "user must enter a username and password to use this computer", you will be prompted for your password when you hit apply. your account is still password protected, you just dont have to type it in anymore to log on. i do this on my windows based mining machines and seti machines. 2. in case you havent figured it out yet, you cannot run more than 13 normal GPUs on that B250 mining expert. there's a reason wildcard doesn't have more than 13 on his. it's not a driver or OS limitation, it's a motherboard limitation. the only way you can get up to 19 cards as designed is to use 6 of the mining specific cards. these have no display outputs, and in some cases different specs than the consumer variant of cards. i dont believe anyone here has used these on SETI, their performance is unknown, and i'm not sure that the app would even recognize it as being able to be used. but it would be fun to find out. though, i'd imagine you will have CPU bottleneck issues trying to run 19 cards since the most threads you can get on that motherboard is 8 with the CPU you already have. ASUS has a newer mining board that claims 20 GPUs (H370 Mining something..), but it seems to have the same limits of needing mining specific cards to get up to the 20 card count. you could hypothetically use the new i9-9900k in that board giving you 16 threads to work with, but you're in uncharted territory then, as i havent found many people use this board yet. i found one youtube video of a guy who was able to get 14 cards working on it, but wouldn't POST with 15 cards. do you have all of your PCIe ports changed over to gen3? or just the main x16 slot. usually the BIOS has different settings for the lanes controlled by the CPU vs the lanes controlled by the PCH, poke around in the BIOS. but I had issues with 2 non-mining ASUS z270 motherboards when trying to run all slots at PCIe gen3 speeds. same symptoms on both; Ubuntu popping up telling me that it encontered a problem, and the logs (syslog and kern.log) filling up with PCIe bus errors, to the point that it filled my entire SSD with 100GB of log files (in an hour) and the OS became unusable and i had to manually clean out the logs and revert back to gen2 speeds. maybe the PCH is a little more robust on the mining specific boards, but my experience with the z270 boards (same basic generation as your B250) shows that i cant handle it. which is unfortunate because it does impact the speed slightly between a PCIe x1 gen2 and a PCIe x1 gen3, gen 3 being about 10% faster for SETI work.

Open the NVIDIA X Server Settings, click on the GPU lines and see what it says for; Bus Type PCIe Generation Maximum PCIe Link Speed Also click on the PowerMizer lines and set the Preferred Mode to Prefer Maximum Performance, Then see what it says for Current PCIe Link Speed It should say 8.0 GT/s And just in case you are confused, and set the BIOS to Mining Mode....You are not Mining, you are running Linux. Mining Mode should be Off. Mine is Off. |

You were right. The setting was defaulted to GEN1. I set it to GEN3 but it doesnt seem to have done much of anything to per unit times... |

I will check the bios setting. |

You're going to have to be a little more descriptive on which driver you're talking about and what problems you are having. The driver downloaded from nVidia has worked fine on all my previous machines, just follow the previous instructions and make sure you have an xorg.conf telling the machine to use the nVidia device(s). On the First install you have to select the option to have the installer build an xorg.conf at the end of the installation. The default install doesn't touch any existing xorg.conf files, or build any new ones. The xorg.conf file is located in /etc/X11. BTW, your times are much slower than they should be. Do you have your BIOS set to PCIe Generation 3? The times you are producing seem to be close to the Generation 1 times you would expect to see. |

TBar, Any idea why I cant seem to get the stock NVIDIA driver installed on a Xeon CPU on an ASUS X79 mobo? Linux works okay if I dont try to install that additional driver. This is another PC I'm talking about. Waiting on your reply, I'm going to try and remove it and start over again or reinstall. Thanks, Dave |

Well, I made some changes to the computing preferences early this morning and its been running all day. All I need now is to get a driver that allows for all 19 cards to be present. |

I find that my miner rig freezes up every day now. Not sure if its the stock driver or the app version but something new is happening. |
