| reorder CUDA devices to match device manager. Posted: 25 Mar 2018 03:52 AM PDT ccminer and other miners use CUDA device order when you use -d 0,1,2 to select cards for mining, but CUDA device order is tricky, it checks for best computing power card and uses it ar #0. For example, if you have a rig with 5x1080 and one 1080ti, you can put the 1080ti in any slot, device manager, afterburner, nvidia-smi will show the device # based on your motherboard's PCI-e bus ordering, but ccminer or any other program that uses CUDA devices will always show 1080ti as #0 and then use motherboards numbering for rest of the cards. I noticed the problem when I had two 1080ti's in 4x1080 rig, they were #4 and #5 in nvidia-smi,in afterburner and device manager, but #0 and #5 in all the miners. I monitor my cards with nvidia-smi, test cards on one rig and then reorder them in other rigs. most of the times I use different miners for different groups of cards and I found the perfect solution - monitor cards by nvidia-smi gpu uuid so I can get results without caring about which rig is holding the card. I had very hard time tracking my cards because I could not match cards I get from nvidia-smi via uuid to ccminer card number. I talked with @tpruvot in discord and he said I can check cuda devices in his ccminer (note: works with tpruvot miner, does not work with Alexis and others). The command is and the result is something like
I clearly saw that the problem is with the miner, not with my actual card ordering. BTW card odering depends on the motherboard, some take all the pci-e slots from closest to CPU to the furthest, some take all x16 lanes in order, then all x8, then all x4, then all x1. Some will just put numbers on mobo for reference. I googled a few pages and found out that many people had the problem with cuda #0 being the most powerful cards. It even screws up 6x1080ti setup if you have a few reference cards and one aftermarket clocked like asus poseidon, geforce aorus xtreme etc. cuda takes that sweet #3 card from nvidia-smi and says "daaaaaamn what a lovely card, this is my #0 card for sure, screw the other 1080ti's in the rig!". Also I digged into nvidia manuals and found out that this most powerful card is picked by default, but you can use normal ordering too. For reference I found this manual http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#env-vars where I found variable So powershell command to change to PCI_BUS_ID is this works for current powershell session. so only if you open powershell, run this command and then run ccminer. want to set it permanently? sure,the command is this should work on linux: also you can just open windows environment variables and put there you can also set it for Machine instead of User, but you need to run powershell as admin rights and it needs to be done only if you use multiple windows users for one mining rig TL:DR you can use magic to use same device numbering in CUDA as you see in device manager, msi afterburner, nvidia-smi and basically all the software that uses pci-e lane ordering. the command in powershell is [link] [comments]  | ||
| Lyra2Rev - 12x 1080TI's varying performance for some cards. Posted: 25 Mar 2018 05:16 AM PDT I have 12x MSI Armor 1080TI's currently running ccminer-tpruvot-v2.2.5 to mine Lyrea2Rev at intensity 22, 200 w +100 core. The output from the miner suggests that some of the cards are outperforming the others with close to twice the MH/s, see screenshot below. Any idea what might be the explanation here? It seems weird that GPU 0,2,4,6,8,10 (even numbers) are the ones going consistently at around 56MH/s and that the odd numbered GPU's are running at around 30MH/s. [link] [comments]  | ||

| Card sitting directly on riser Posted: 25 Mar 2018 04:14 AM PDT I'm assembling a rig with assorted unmatched cards using a shelf as the frame. I had planned to hang the cards from the top shelf, but one of the cards (an MSI Gaming X) doesn't have anything on one end that I can put a zip tie through. Hanging them vertically doesn't work space-wise, either. I've looked at this from every angle and unless I'm going to start over, the only option I see is to place the card on top of the shelf sitting directly on top of its riser. I can secure it into that position, so no problems in that regard. But is there any risk associated with having a card sit directly on its riser (breakage, heat, etc.)? [link] [comments]  | ||
| Rig and monitor on separate circuits Posted: 25 Mar 2018 12:21 AM PDT Is this okay? I did some cursory Google searching and couldn't find anything. I know for example it's best to keep risers on the same PSU as the GPUs they're attached to. Just wondering there's a similar issue here, or if it's okay to have a monitor plugged into a different outlet on a totally separate circuit while being connected to the rig via HDMI. Thoughts?

| Let's find out the price of GPUs now after such a price hike. Posted: 24 Mar 2018 11:15 PM PDT Now that the crypto market is not high as it was back in December, the price of gpu spiked up very much and now the market is down for almost a month the prices of gpu have seen some correction and there prices have lowered just a little bit. My aim for this post is to find out where in the world the prices of gpus are the lowest, as I want to build a mining farm so getting gpus as lowest as possible results in fast ROI. So please comment the prices of Amd 570/580, gtx 1070/1080ti with your country name. Together we can find the best price and this post can help others who are looking for gpus. I am from India and the current price of amd 570 4gb is Rupees 30000. And gtx 1070 is around 38000. ( 1$= 65 rs) ( the rates are including 18% GST Tax so if your country has any tax please mention that too) . During the price hike 570 was at 42000 and gtx 1070 were sold at 52000 rs. So guys please comment and thank you. [link] [comments]  | ||
| Posted: 24 Mar 2018 10:43 AM PDT So, seeing as how payouts on the mainstream sources have been dropping so much, I've decided to start scouring the bitcointalk announcement thread for new coins. My tactic will be to devote about 60-70% of my mining time to safe bets (nicehash, miningpoolhub, etc), and 30-40% to longshots that might pay off one day.... Or not. Anyhow I've been mining Aquachain for the better part of the week, and thought I'd share it if anyone else is interested. Here is the announcement thread https://bitcointalk.org/index.php?topic=3138231.0 Very new coin, relatively small supply. 42m total, with 1 coin block reward every 4 minutes. Anyway... That was it. I'll continue to share the random longshot coins I come across if people are interested. Good luck! [link] [comments]  | ||
| Posted: 24 Mar 2018 01:48 PM PDT Hi, I have been letting my gpu miners run for months now. It looks like they can use some maintenance, eg. dust cleaning. Do you guys have any suggestions, or can give me a link to a guide, as to how to effectively do that? I am thinking of buying those canned gas dust cleaners from amazon. Thanks!

| Posted: 24 Mar 2018 02:09 PM PDT Good Day Fellow Miners! I am possibly going to be building a large farm out of state that I will manage remotely and will need to make sure that there is always internet available at really any cost. There will be hardwired network coming in from the local utility, but would also like a wireless option, as there is only one high speed provider. I have researched and have not found much other than this: www.rocketfailover.com . Does anyone have any experience with them and or any other suggestions? [link] [comments]  | ||
| How does mining malware work without knowing the target hardware? Posted: 24 Mar 2018 12:04 PM PDT Couldn't find a good ask subreddit for this so sorry if this doesn't belong here. How does mining malware work? Does javascript executing in the browser have direct access to the GPU? What if there is no discrete GPU? Surely CPU mining is so inefficient its not even worth it, right? [link] [comments]  | ||
| Posted: 24 Mar 2018 11:52 AM PDT I don't have any verified trades in hardware swap. And ain't crazy about ebay. Any recommendations? [link] [comments]  | ||

Tell me what do you guys think. Edit: Thanks business monk, I forgot to tell that I'm planning to tinker with their fans too ( https://www.youtube.com/watch?v=h6hvsqUEtZ4) since I live in Asia and want them to last for more than 3 years, building this to Vegas seems worth the hassle. Edit2: I might do this on some of my cards(https://www.youtube.com/watch?v=Iegpwo9SqSg) (https://www.youtube.com/watch?v=-yQHAMz1v5g) New link (https://pcpartpicker.com/list/J4mf8Y) [link] [comments]  | ||
