    New (1st) Mining Rig help. What did I fry?

    Posted: 17 Feb 2018 04:39 AM PST

    So I just built my 1st mining rig, which was my first ever complete PC build. I used an ASRock H81Pro BTC mobo, EVGA Supernova 1200P2 PSU and MintCell Ver 008s multipowered risers. GPUs are 3x 1060 6b and 3x 1070s.

    The system was up and running, and temps were fine. I got Windows 10 loaded with no issues while running the monitor through hdmi on GPU#1 (1070) which was the only one connected at the time. I got the drivers, downloaded Nicehash and completed benchmarks. I tested with some mining and saw normal hashrates and monitored the temps. All were good. I shut down and added GPU#2, 1070. Booted with no issues and Nicehash recognized it immediately and started mining using both. When I added the 3rd GPU (1060 6b) I could not get any video out from the system. I tried hdmi out from all 3 GPUs as well as the motherboard. I have heard that risers are sometimes faulty so I first tried changing that but it still would not boot. I then started adjusting how they were seated into the PCIe slots in the motherboard because I noticed they never stayed too firmly planted with the pressure from the USB cables. After rebooting and readjusting several times I got it to boot once, but the GPU was nor recognized, so I tried again. This time, as I tried to turn the PC on, the GPU fans and the CPU fan would power on for about 1 second and then power off, no beeping. I tried a few times to power the system on like this and it kept doing the same thing. My last attempt, the system would not even attempt to power on. I was going to then remove all but minimum required hardware but when I removed the riser I had been readjusting, I thought I saw a shaving of one of the contacts come off inside the PCIe slot (I couldn't find it after). I removed all unnecessary hardware but it still would not power on. I removed the switch and tried manually shorting to power on, nothing. What could be happening here? I don't have any spare parts to swap out to test.

    Edit - as far as I remember, the usb mouse is still powering up when everything is plugged in, if that helps diagnose.

    Any help is greatly appreciated!

    Which 1080ti 11gb card?

    Posted: 17 Feb 2018 07:42 AM PST

    I am building an 6-8 card rig and through our it partner channel can get 1080ti cards. They are not MSRP pricing but still less than most places.

    I am looking to mine Zcash, Dash, monero, eth, BTC or decentraland.

    Based on the below what would be the best cards to get based on the pricing within?

    Thanks for offering up some feedback.

    pricing

    Some cards have a $100 price difference and although might be better, could allow me to get an additional card if by 6-8

    Checking for other options as to why one GPU isn't working

    Posted: 17 Feb 2018 06:46 AM PST

    Before I drive out to my rig, Just wanted to see what other people think of this situation: 9 card 1080ti rig, 1 card isn't mining. The card shows up on MSI afterburner, but I cannot do anything to it. It shows up on awesomeminer, but not on the actual mining programs (ccminer, etc). When I try to benchmark on awesomeminer, it benchmarks 8 cards, not 9. When I try to benchmark that individual card, the benchmark crashes. On windows, I can see all 9 cards in device manager. All of these I'm thinking its a bad riser. Wanted to see what everyone else thinks, and if there's something I can do on a software/remote login side before I make the drive. Thoughts?

    Problem with more cards on rig

    Posted: 17 Feb 2018 05:29 AM PST

    Hello, I mine ZCash for 1-2 months and I used 4 x GTX 1070. Now I want to add 1 x GTX 1070 more. I tried to add it, but after starting of pc I cant get any visual contact from my rig, I tried teamviewer and RDP but it doesnt work too. Now it also doesnt work with 4 card soo. Rig works until 3 cards are connected, after that I cant get visual response from rig or I can start it, but I see only 3 cards.

    I have power supply 1200W so its not problem with it and I also tried to switch risers, connectors etc. Every card is working but they are not working together.

    Thanks very much

    how much profit have you made so far?

    Posted: 17 Feb 2018 05:25 AM PST

    just as the title states. so talk about the money side of things. i just started and i havent even broke even with this machine yet (1050 ti x 5) only another 7 months to go

    I think we're using the term ROI wrong - we should be talking about the break even point.

    Posted: 16 Feb 2018 09:36 AM PST

    Everyone talks about ROI but ROI is your total return on investment, which you don't know until you are done mining and have retired your rig. (paid $10,000 for your rig, ran it for 2 years and made $30,000, your ROI is ($30k - $10k)/$10k = a 2x ROI.

    What most people are referring to is your break even, the point at which you've made enough money to cover your initial investment.

    ROI is measured in percent, break even if measured in time. So saying you have a 6 month ROI makes little sense.

    Just food for thought.

    Stumped With Rig Setup

    Posted: 17 Feb 2018 04:56 AM PST

    Hey guys so I built my first actual rig... up until this point I was just mining out of the Pc cases. I've always been hesitant to build a big rig because of all the riser failure horror stories I hear about, but ultimately decided it would be better.

    I am using the following: MSI Z270 Gaming M3, G3930, 4gb of ram, 2 seasonic PSUs. And a mix of different MSI 1060s. Got some armor, twin froze, etc.

    Now my issue is using more than 3 cards. 3 in fine... Anymore and the system crashes due to Nvidia related reasons sometimes it BSODS with the nvidia driver as the culprit. And sometimes I just get GPU unspecified failure in the mining command prompt.

    I've tried to following with no luck:

    -enabled and disabled the setting in the BIOS that says more than 4 card support.

    • SET PCI to Gen 2.

    • I've been playing with the PCI Latency Timer. However am not familiar with what's the best for this setting. I've read 16 clocks a GPU is ideal but, again I am very unfamilar with this particular setting.

    • tried reinstalling drivers, updated latest bios, etc, etc.

    • tried switching out risers. However It doesn't matter the order any 3 cards will work just fine but plug in one more and the system is unhappy.

    • I increased Virtual Memory to 32GB

    • turned off any power saving features related to PCI express.

    • Tried a mix of stock settings + undervolts made. No difference.

    Perhaps there's just something I've overlooked. Maybe even silly simple... but was hoping for some help. Thanks!

    [Question] Linux miner bash question

    Posted: 17 Feb 2018 12:48 AM PST

    Hey guys, I am an occasional unix/linux user who recently started mining using Ubuntu 16.04 and was wondering how to bring a background process into the foreground of the terminal.

    My miner auto-starts on boot and I would like the be able to bring the application to one of my SSH sessions to monitor without having to worry about the application closing on the end of the session.

    Does anyone know how to do this?

    Thanks!

    Non-branded blower-style 1070: Mining 24/7 a good idea?

    Posted: 17 Feb 2018 03:46 AM PST

    Disclaimer I'm a hardware guy and have a fleet of 1080Ti's so this isn't another noob retard question. I tend to prefer quality equipment and have never owned/used hardware from unknown brands with no reputation. I recently found a GTX 1070 in my parent's home (prebuilt) desktop that's basically "free" (cost-wise and the fact it's never used in the desktop's daily web-browsing activities) and have given it a new home with a proper high-quality Asus motherboard and Seasonic Titanium PSU.

    My problem with is the GPU has a sketchy as shit plastic housing with a blower-style cooler (kinda looks like the AMD one) that looks/feels worse than Nvidia's stock cooler and flexes a bit when you hold the card. It could pass as a China-knockoff especially with a big "GTX 1070" printed on the side in a shitty font, but I've verified it hashes on par with an actual 1070.

    Would something like this be safe to run 24/7 or should I try to sell it? My concern isn't with the card itself dying, but more the possibility of it damaging anything it's connected to if it does kill itself.

    1080 ti poseidon hybrid

    Posted: 17 Feb 2018 02:31 AM PST

    Hello, I bought this card and It produces weird clicking/popping noise from one of the vents. I've checked, no cables are being hit by vents. I use aircooling not watercooling.

    What could it be? PSU is RM650X Powering only this card

    Why AMD cards are better than Nvidias on Cryptonote algorithms?

    Posted: 16 Feb 2018 10:06 PM PST

    For example a GTX 1080 generates 600 H/S but a Rx 580 generates 1000 H/S, but they are better in case of zk-Snark (ZCash)

    Modified bios & 5+ GPU driver error.

    Posted: 16 Feb 2018 10:15 PM PST

    I am trying to get this mining rig going. However whenever I add more than 4 GPU, it gives a driver error in OS screen load. I tried nvOC, EthOS, HiveOS and Ubuntu. All same. Boots fine with 4 cards but hangs and gives error with 5 cards or more.

    The error I am getting: lid PCI ROM header signature: expecting 0xaa55, got 0xffff

    Anyone had this issue and able to fix this?

    Thoughts on Coinhive.com (& other background "javascript miners") as a monetization strategy for mining-related Apps?

    Posted: 16 Feb 2018 06:04 PM PST

    Heya. Title.

    To elaborate - is there a positive / negative connotation with this kind of thing in this community? It seems like a shady thing at first thought - but that's probably only because of it's potential for "bad faith" usage (ex: UFC.com getting caught secretly running it a few months ago). If it was explicitly stated what was happening in exchange for the service / product, AND the users were fairly knowledgeable about such things - it might not be quite so detestable...? Maybe even preferable for some...? Eh?

    For someone launching a web-based product aimed at miners who is looking to "keep the lights on" so to speak, would you consider this viable - or a non-starter?

    (And who knows if it is even viable on it's face.. i.e. if it scales up well enough with users to even be worth the bother)

    Thoughts? Has anyone used something similar before, encountered it in a "freemium" type of web app?

    Otherwise - Happy Friday!
