    Any advices to make my cooling summer solution well?

    Posted: 25 Apr 2018 07:47 AM PDT

    I've got one 6x1070ti rig and one 1x1080ti(will add 3 1080ti in near future) mining zcash. Both rigs stands in a room near balcony with both two opened windows (balcony is like 2.5x6m square). Temp is about +12-15C in street and about +25C in room. The most hottest cards temperatures are 63-65C with 85% fan atm. I'm pretty sure in late June-July it will be 35C+ at the street. I know that using AC is a bad idea, so I'm thinking about moving both rigs to balcony, put reflective membrane on both windows to avoid sun lights (balcony stands on the sunny side), put 1 powerful fan on window at one side of balcony to exhaust hot air, and on the other side of balcony - just open the window for getting "normal" air from the street. Is it a good strategy if my goal is making air temperature on the balcony close to street air temp? Maybe I need to put second fan to provide inline air or some additional fan(s) to circulate this air on the balcony? Im sorry for my english

    Mining from AWS, how efficient, is it profitable?

    Posted: 25 Apr 2018 07:56 AM PDT

    I know you can get servers with GPU's in AWS, but is it cost effective/profitable as well?

    UPDATE: My ghetto rig

    Ask /r/gpumining - How do I simulate mining rigs in my game?

    Posted: 25 Apr 2018 02:40 AM PDT

    Hi guys - bit of a weird question for you...

    I recently finished a beta version of a side project I've been working on. It's a basic crypto trading sim / game - for those who are interested: https://cryptoempire.io/

    I'm trying to think of ways to make it a little more fun / engaging, and one of the feature requests I had was to put in a mining rig mechanic... So the idea is that you could take some of the 'money' that you get when you create an account and spend it on mining rigs that would add to your total crypto balance.

    Unfortunately I know next to nothing about crypto mining. I was thinking I could base the numbers off http://www.whattomine.com/, but any ideas on how much an in-game mining rig should cost? And should I have both GPU and ASIC options?

    Thanks!

    help Optimizing a 6 x AMD580 rig.

    Posted: 25 Apr 2018 01:37 AM PDT

    I currently have a system running with 6 AMD580's. using Nicehash-legacy, 2 of them run Dagger-Hashimoto algorythm at 27.5Mh/s, while the other 4 only run at 22.5Mh/s.

    I done a clean install of windows 10 once with AMD crimson blockchain driver, and once with the newest AMD drivers, both given same results.

    I am quite new at this, and heard about things like pixelpatcher. I would like to know what programs people installed for optimizing their cards and in what order to install them.

    Another thing i would be interested in is optimizing it's power consumption, at the moment it is sitting at 1188W, would like to bring that down.

    I am quite new at mining. That said i would like to try as many things as i can, and dont fear a reinstall to try something different. I'm in it to learn, so any feedback is welcome :)

    If you use my multipoolminer v2.7.1.4 repo, a new version has been released

    Posted: 24 Apr 2018 07:32 PM PDT

    The latest version v2.7.1.4.4 includes version updates to Cast Nvidia miner, xmr-stak (FireIce), xmrig, JayDDee cpu miners, and excavator. Updated JayDDee miners finally adds cryptonightv7 as does excavator.

    If you don't use any of the mentioned miners, this version can be skipped as v2.7.1.4.3 is still good otherwise.

    Server PSU with Molex Risers

    Posted: 24 Apr 2018 11:02 PM PDT

    I have a 9 x GPU rig and 6 of the risers have 6 pin PCIe inputs and the other 3 are molex risers. I'm able to connect directly to the 6 pin PCIe risers without any issues with the cables that came with my breakout board. Even though I know it's not safe to connect these PCIe risers with a daisy-chained SATA cable, I have checked that it will power up the risers, and it works.

    I have 2 questions...the first is, what is the best way to connect the molex risers to my server PSU? I haven't seen any adapters online that would allow me to connect directly to the molex from the server PSU. Preferably I would like to power 2 risers from 1 6-pin cable. The second question is why do the Molex PCIe risers not get powered on by the daisy-chained SATA cable? This cable seems to power the PCIe risers just fine, but shows no results when connected to my molex risers.

    Experienced users - coin switching software

    Posted: 24 Apr 2018 06:38 PM PDT

    Hello everyone.

    There's some altcoins popping up on whattomine that looks significantly more profitable than ETH right now.

    I'd like to use some software to automate how I mine alt coins.

    I just plan on mining the alts, then immediately trading for ETH, BTC, or BNB.

    What's the best software out right now and do I need to generate a wallet for each coin that the software would consider?

    Thank you.

    How much to charge to clean an asic machine or GPU rig?

    Posted: 24 Apr 2018 11:48 PM PDT

    A farm owner asked me if I can clean his asic machines once a month, his farm consists of 250 machines, he has all asics on this farm but he has another farm with over 300 GPU rigs too. I wanted to know how to charge for such a service and or how much will you be willing to pay per machine for such a service. Also, we will be providing Ad-hoc technical support to them too on a 'need to' basis, and suggestion on how much to charge for that will also be highly appreciated.

    Octominer X8 nVidia build (Equihash / SHA3 / Lyra2rev2 hashrates)

    Posted: 24 Apr 2018 08:18 AM PDT

    Octominer 8X nVidia mixed mining rig (Equihash, SHA3, Lyra2rev2 etc)

    Picture of the 8 card set up https://imgur.com/a/309V9rv

    Parts:

    Octominer B8 Plus Motherboard (8 GPU)

    Octominer Server Style Case

    HP Server PSU 1200 W

    Parallel Miner Breakout Board

    4 x Thermaltake fans as Intake

    3 x Delta fans as Exhaust

    Cards:

    MSI Armor 1080

    Zotac Mini 1080

    EVGA SC 1070TI

    2 x Asus Strix 1060 6GB

    Zotac Amp! 1060 6GB

    MSI Gaming X 1060 6GB

    MSI 1050 TI

    Why all different cards? I never bought 6 or 8 GPUs at once, I've always been scaling slowly, buying cards one by one searching for good deals, often used ones. That's why my rigs are always "mutants".

    Hashrates: For Equihash, I am getting around 2900 SOL/s – with very modest overclocks, so definitely more possible. For SHA3 (Nexus) I am getting around 950 mh/s. But of course a Rig like this is also very suitable for Neoscrypt / Lyra2rev2 etc. (f.e. around 250-260 mh/s for Lyra2Rev2).

    Temperatures: GPU temps stay below 60 ° C mostly, except for the msi armor 1080, who generally runs a bit hotter. So I modded the 4 Thermaltake fans as intake, because of the big Asus 1060 cards (more space in the case) but I'm happy with the mod. The 3 remaining Delta fans are loud, but one single L3+ is still louder than my whole Octominer rig, so no problem here.

    For review, I am very happy with building, setting up and stability. I build open-air style rigs before, but the "server style way" was still new to me. Only under Win10 did I finally get some problems with the board when I went from a 4 card setup I had for some time (testing, waiting for a bigger breakout board etc) to the final 8 card setup. So first, I was only able to get 4 cards recognized, but strangely even cards which were recognized before in another slot (f.e. Msi gaming X 1060) was suddenly not found anymore.

    I went through a long troubleshooting process with recommendations from Octominer (their homepage and their live-chat), as well as my own trouble shooting. Getting up to 5 cards and eventually 7 of 8, but never all the cards. What finally did it for me (after 5 – 10 trys of different things) was fiddling a HDMI/DVI cable through to the first card, disabling internal graphics, cleaning all drivers from the system and re-installing everything with some more reboots in between. Then I had all 8 cards recognized (Bios update or other bios options did not work for me, but did for other people in the past). And yes, you would not have these problems with HiveOS etc, but I still wanted to get it to work.

    I wanted to share this here in text form to give info about my experiences and problems with the build, instead of just posting a videolink here, but I also made a video about the whole building process (a how to so to say) which you can find here: https://youtu.be/0sz6hWXpCXA

    Also, I made a separate video about the whole "troubleshooting with Win10" for people who might have similar problems (unrecognized cards, frozen bios, no boot etc.). you can find it here: https://youtu.be/y2n55rESnYY

    That's it, if you have any questions about the rig don't hesitate.

    What are you currently mining and why?

    Posted: 24 Apr 2018 09:47 AM PDT

    I am currently mining RVN, for speculative reasons. Once I hit a balance of 1000, I will probably switch back to Equihash on MPH, it seems to be the most consistently profitable.

    How do you guys handle static?

    Posted: 24 Apr 2018 09:49 AM PDT

    Question for everyone here:

    How do you guys handle static buildup?

    I run a medium/large mine with roughly 100 GPUs in my basement. Within the last 2 weeks or so, the weather in my area has gotten much warmer (no idea if there's a correlation between static and warm weather), and I am constantly running downstairs to reboot a rig. I highly suspect static is the culprit, as merely walking into the room with all my rigs sometimes triggers another visible shock and I'll have to reboot a separate rig than the reason I went down in the first place. In addition (but not totally detrimental), the rest of my house upstairs is very static-y as well with lots of shocks everywhere.

    Right now the rigs are mounted on a mixture of PVC frames and plastic shelving. The basement is carpeted (that's not going to change). This has not been an issue in the past (been mining for about 1 1/2 years now at this scale).

    Just wondering how the community here deals with it :)
