And I'm certain it would be possible with a titanium efficient PSU.
No - it would not be I can definitely see power draw from the wall at around 900w, and less.
You will not get 900W from wall hashing with 6 RX 480 with rate of 180MHs Well im running several 5 X RX470 rigs at ~620W each, hashing at 133Mh/s+ and while I have no 6 slot motherboards to test, adding one card to this setup would push the Hash to 170Mh/s and the power to 750W. So I see no reason why 6 Rx480's cant run under 850W or even, possibly 800W. |

@Eliovp I still wait your test with 2100 mhz - 1500 strap.
@All VDDC can easily drop with Msi Afterburner. Just edit your bios for gpu frequency, ram frequency and also for ram straps. TDP and VDDC can tune with Msi Afterburner.
Don't consider the idiots who drop the VDDC and give no information. They behave as if they are Mandrake.
1500 strap all the way up, frame buffer will drop, as so will hashrate. I only have Samsung cards and a Micron card to test with, perhaps on hynix this will work, i can't say. Still, i doubt it  Btw, your pictures are unclear, like always. No clear info. have you ever done anything for the community? Nope i don't think so. A lot of words. But nothing to show for. Adding VDDC Offset will let the voltage controller start calculating the needed voltage for a specific DPM at a lower start. Therefor it is better to do it like this. You have lots to learn young padowan :p Such a mature reply. I would have lost my shit right there. Many thanks for all that you do share Eliovp, it helps/means a lot to us even if we don't always say it. |

I am looking for Asrock mobo for long in India which Supports 6 GPU?
. I hunted long for Asrock H81 Pro Btc But
- It's out of stock on every e-commerce site in India.
- Out of Stock on Newegg.com
- available on Amazon but is not deleivering to India.
- available on Ebay at $150 . prepaid order from US but after one month it says not available and refunded the 150$.
I have been mailing Asrock Continuously but no Response from them . Kindly Help what Mobo and How can I get it in India? Or which 6 GPU supporting Mobo is available in India?
URGENT! Thanks.
Aah a fellow Indian Miner. Do not look for 6 card motherboards, the only ones you can get would be from aliexpress, and with a 20 day shipping. Also you would need a 1000W+ PSU which makes resale difficult, especially in India. Instead, as phillipma1957 suggested stick to 4 or 5 card rigs, and you can get plenty of motherboards for those here locally. What city are you in? |

Claymore my miner thread hangs frequently, and it wont restart. I mean when remote-connect to the machine and on the miner window press down arrow "miner thread hanged, restarting" message pops up, but untill I do so, the machine just stays in freeze mode for 4 - 6 hours causing me significant loss. I need to keep checking on machines almost regular. I have set the miner to restart every 60 minutes with -r 60 but nothing happens. I'm using Ver 7.1 of your miner on RX 470's, 16.9.2 drivers on Win 10.

Nice speed for that cards.
What settings did you applied? 1500Mhz memory strap? Which clocks & volts?
For those results I had used the 1375 straps. The cards have been stable for almost a week of 24/7 operation. But recently i checked with HWinfo and saw that half the cards were getting a lot of memory errors (almost all of them minor errors, so didnt result in invalid shares). While these memory erroes may decrease the cards life in the long term ( from like 5 years to 2 years, which is basically inconsequential with POS ) they were not impacting claymore reported hashrates. Hashrates at the pool were consistently 10% lower so that made me curious. To test this thoroughly I tried gaming on these cards with the 1375 strap and while game benches did not crash, I could see fram drops everywhere and stuttering telling me that the memory was struggling to keep up, and having to possibly rework, which could explain my consistently 10% lower pool hashrate. I then decided to go back to the 1500 straps and they have been rock solid at ETH 26.8/ SIA 241 dual mining with the same clocks 1050/870 1870/870 and I am going to be sticking to these settings. For a few cards you can perhaps check if the 1375 strap is stable for you and check in HWinfo for memory errors. If your cards pass, that memory strap will yield godlike performance/watt. But since I run about 30 cards, its hard to track and manage which cards run at what strap and settings etc so I just go with the minimum stable settings across the board. |

No need to push them that hard, you would generate a lot of heat, wear out the fans soon and maybe even burn your risers seeing how much power Polaris pulls through the PCIe slot. Just copy the 1375 memory strap timings to all subsequent straps and voila, dual mining ETH/SIA 27.35/246 Mh/s at low low clocks of Core 1050/870 and Mem 1870/870 while drawing under 120W at the wall.  Do you run the 4Gb reference card ? Yup, the RX 470 OC reference silver colored card with backplate. |

Yup, can confirm, Ethereum still under attack, im mining at ethermine and get the same message.

Considering your Budget of 2k, I would recommend the following : Get the ASRock FM2A58+ http://www.newegg.com/Product/Product.aspx?Item=N82E16813157517And couple it with 4gb ddr3, an AMD A4 APU and a cheap 120gb SSD This combo should set you back by ~$120 and is the cheapest 5-GPU solution I know of Add to the mix 5 X Sapphire 4gb Rx 470 OC at $200 each or less ( Get this specific version because they have back-plates and inexpensive/run cool). You will need powered risers and a 750W PSU ( thats all the power you need for the RX 470 and a smaller wattage PSU is easier to sell off later ). If you are able to find powered risers cheap, you can get them and the PSU for under $100 total. Build a simple open air frame for the assembly, follow this guide here : https://www.youtube.com/watch?v=OfE_QidD75MInstall Windows 10 ( free if you dont activate it ) and follow one of the several guides posted on this portal, and you have yourself a functional ETH Miner. I would recommend ETH because it has long term potential if you plan to hold it, and has been pretty profitable to mine for a while now. That brings our total cost to about $1250. If you have the system optimized well (read through the forum posts, lots of details on optimizations, ping me if you cant find them), One such machine would consume about ~500W from the wall, and running 24/7 would generate about 24 ETH per month. At current rates of $11.7 that's about $280 per month (although this amount will reduce each month as network difficulty rises). If you are up for it, you can stretch your budget a little and set up two of these. Enjoy Mining. Also, per your offer of 5% of the mining reward for the first 50 days, that comes to about 40ETH. Shall I ping you my Wallet Address?  This is sounding like a contender!  Is this machine designated for ETH or can it be used to mine any coin? Do not listen to him. AMD cards sucks anywhere outside Hashimoto and Cryptonight. My 1070 is perfect and do so much better than my R9 380s. It is a also a lot more power efficient. What do your GTX 1070 hash at for ETH? Because my $199 RX 470 can Hash at 28MH/s with undervolting/overclocking tweaks, and consume about a 100W each. I have five 5-card rigs drawing a combined of 2.6KW from the wall, and earning me ~4.2 ETH per day. I believe the GTX 1070's get a maximum of 32MH/s at a 145W power draw. At $399 each ( good luck with finding them at that price ) plus the added power draw demanding a beefier PSU, ( 1000W atleast ) that drives a 5 Card Rig cost up from $1250 to $2300 (Extra $200X5 for the cards, $50 for the PSU). One Rig. For a combined maximum Hash rate of 160. I do not know about you, but I want my investment to ROI asap and for that I'd anyday take the $1250 140MH/s AMD rig over your version. Not to mention how much easier it is to dispose off of cheaper GPU's/PSU's. Also ETH is the first time in a while that mining has been profitable enough to put money into a rig, and it will POS soon so you absolutely need to ROI before that day comes. Anyways that's my two cents. And speaking of cents, here's my ETH Wallet address : 0x60eD77244Ad16CC83c596af10Ee816F5241d2352 You know what to do |

This config can be used for any of the several crypto currencies currently mined on computers ( ETH, XMR, LBRY etc ). For some of them, AMD cards are better, and for others Nvidia cards. But there's hardly any bang-for-buck competition for the AMD RX 470 and that helps profitability/ROI period. Let me know if you cant find guides to help this setup. I would also recommend http://forum.ethereum.org/ as there's several detailed setup and optimization guides there, including mine. |
