Running 6 cards on a onda riserless mobo, 1500w at the wall, 490mh/s.
1575 clock, 860mv, 950 mem phoenix miner.
Something seems to be sucking up power unnecessarily in your setup - I ran same settings but w/ my mem just a touch lower (935), and only saw 215w/card - looks like you're at 240-245 for some reason, which is generally more in-line w/ the 90Mh/s config. My rig has 4x 4000rpm fans (or 7x 3500rpm fans), just the mobo + fans with no gpu attached is ~140w. Even so, it's less efficient that yours. Might be my psus hitting 90%+ load, I use the Evga 1600t2. My Radeon VIIs run hot! I have the mem at 1500 core 975 undervolt 875 and they still get up to 80 degrees in my shed with fans blowing on them. Not sure I made a wise buy my hash rate for eth is down to 75. 80 - 90 make it a deal but I don't think it can run long at 85 degrees.
That's just the hotspot temp? If so that's within spec. Mine are 70-75 degrees in MSI AB, but 85-90 hotspot temp. No idea what temp that is, I'm using simpleos and it says temp is in the 80s. |

I have 8 Radeon VIIs and they run hot, 80 degrees and 75mh on eth. RX 580s are a little more power but a hell of a lot cheaper card. If I could run a cool stable 90mh I would buy more but mid 70s makes them less of a buy, still more efficient buy not buy a huge margin.

What gear are you planning on buying? I've been expanding my small farm buying z11s, Radeon VIIs, GTX 1660s and RX 580s. Right now is is prime time before a big bull and price of gear sky rockets.

I just zip tie a case fan to the gpu.

When I first started mining with my Radon VII is was making $1 a day now its $1.57 if things keep going up those numbers will improve.

I'm mining grin on nano pool right now and its working great, but i did switch my eth mining to Ethermine seems better. I had a similar problem with lux pool and my z11s but I rebooted and it corrected.

Never touch any adapter if you don't want to burn your house down!
1 slot in your PSU for 1 slot in your GPU, if you want to make it correct. So you can fire up 4 GPU's. A 5th card if you use the last 9th PCIe and a good (not cheap!) CPU/PCIe cable.
Many ppl will say "Hey, just use 1 cable for 1 GPU. Get any cheap chinese adapter and its fine."... Never do this! These cables were made cheaply and get very hot and if you are unlucky, it can burn.
Edit: Yes, just connect 1 of these double cables (6+2 and 6) into 1 slot in your GPU, forget the 6 Pin.
DON'T split the remaining 6 Pin with an adapter into 8 Pin and connect the second slot of that same GPU!
Hey mate, thanks for reply man. "Edit: Yes, just connect 1 of these double cables (6+2 and 6) into 1 slot in your GPU, forget the 6 Pin." The RADEON VII requires 2x 8-pin power. You're saying to connect only 1 of the 6+2 and 6 into 1 slot in the GPU, will the GPU still work, because 2x 8-pin power is required? "DON'T split the remaining 6 Pin with an adapter into 8 Pin and connect the second slot of that same GPU!" Ouch! I was going to do that tomorrow when the adapter arrived. Thanks man, I will give it a miss now. I still have my Corsiar PSU, that has the exact cables that are required for RADEON VII to work, do you think its OK to use corsair cables? I have those adapters and one did burn. I just buy another psu, they are cheap. |

Nicehash is okay, if you don't mind pretty high mining fees (5% for payouts less than 0.1BTC to external wallets). The higher fees are partly offset by the fact that their miner always finds the most profitable coin to mine. They had a huge hack two years ago, and they lost lots of bitcoin, and many (including me) lost some of my mining profits. However they've been slowly paying back miners for the lost money. The fact that they've been around for a while, and that they try to pay miners back and do the right thing is why I still trust them. It's an okay way to acquire Bitcoin. For lesser fees, I use Nanopool for Ethereum mining, and over the years I've had zero problems with them. You can then use an exchange with much lower fees to convert your mined Eth to Bitcoin. I like their clean interface, and you can see one of my miners (2x 1060, 2x R-VII) mining currently there: https://eth.nanopool.org/account/0xa63ffc523e284bfb4a09b46ed2336afe824c57ebI wouldn't run 4x Radeon VII's in the bedroom unless you have earplugs, or are a very deep sleeper.  Also, do you need to cool down your house with air conditioning units? Depending on the climate you live in, AC units can use heaps of electricity trying to cool down mining rigs, and that's why lots of miners choose to run them outside, in the garage or at the patio, for example. Unless you have free electricity, or live in a cold area where you want to warm up your house by mining, I wouldn't run them inside. Today, I finally ordered 6 x AMD Radeon VII, I've been planning for quite some time now. Fingers crossed it should be delivered tomorrow or Saturday, also ordered 2 x Asus GTX 1070 OC 8GB. So now my small rig contains: 6 x Asus GTX 1070 0C 8GB 6 X MSI AMD Radeon VII 16GB I think having all 6 Radeon VII in 1 rig will be a pain, plus alot of undervolt would be required. I will install 4 GPUs first, check the performance and add 1 GPU at a time if possible. Yeah, I heard about the Nicehash hack. I was affected not much but still, now their making good progress reimbursed more than 50% already. They're also working on Nicehash v3, I think. My current rig has 5 x 120mm fans already installed which is running 4 x Asus GTX 1070 0C 8GB. It keeps the rig very cool and working great. After installing the 2nd rig, if more fans are required I could always purchase : https://www.amazon.co.uk/Oypla-Electrical-Chrome-Standing-Hydroponic/dp/B0182K76UQ/ref=sr_1_4?keywords=gym+fan&qid=1558040716&s=gateway&sr=8-4 , now these suckers are powerful! What makes you decide to order VII? i have a mining rig (3x 1070) and i wanna add more but i have some choices like 1060, add more 1070 or VII. but after doing some research and i got the fact what the power draw for VII is doubled from how much consumed by 1060 and 1070. Is there a reason for that? VII has a lower core clock too. Double the power draw with 3 times the eth hashing power of a 1070. |

Adding "--worksize 64" increased the hash rate.
whats your hash rate now? |

I use simple os and run team red miner for xmr and claymore for eth.

I have 7 and they work best for eth and xmr.

It seems that this video card is currently one of the leaders among the video cards for mining.
Through the use of more efficient memory, tGTX1660Ti shows a hash rate comparable to 1070 at a much lower price and power consumption (roughly corresponding to the GTX1060 level)
I don't even know what could be better?!
Yes most of the mining algorithms has even better performance them 1070. Prices is very attractive, compare to also very efficient cards like Radeon VII. that's why i used 1070 rather than radeon VII. Radeon VII is less efficient than 1070 caused by it has consumed a lot of electricity almost doubled from how much has already consumed by 1070. 1070 is also having a better core clock rather than radeon VII. I still prefer GTX 1070 TI rather than radeon VII but 1070 should be at the top of the best GPU that can be used to mine crypto. It's possible to reduce the power consumption of Radeon VII by reducing the voltage of the core to values about 800 mV. In this mode, the video card will consume about 200 watts with 70-80 Mh/s In any case, it's uncertain purchase now, given the cost of this card. I have both, Radeon viis and 1660 tis and they are about the same dollar earned per dollar spent electricity and dollar spent on card vs dollars earned. Nvidia has more mining options and but its sure is nice to have one rig earning as much as 3 Nvidia rigs. |

I mine and hold coins but to me its two separate areas of investments.
Mining is a business were you can generate income and is run more like a business. Holding coins is speculation. Comparing thee two is like comparing stocks to bonds. They each have different advantages and risk.
Mining produces daily income but to be long term profitable you have to have low overhead, low electrical cost. Your gear can retain value while it produces income, gear prices fluctuate less then coin prices. With low overhead income can keep coming in even in a bear market.
Buying coins is more speculative, no overhead but you are at the whims of the markets not reliable to produce daily income but your potential long term gains are huge.

Are they measuring the temp different them other cards? Aren't the higher temps normal?

Although it looks expensive, but according to many reviews both here and otherwise it looks promising. Will visit one of my friends who is a mining freak and get first-hand knowledge of it.
I just bought 3 open box for $629 each, mining xmr right now zero problems. After electricity they are making slight over a dollar a day each using less then 200 watts each. It would take 3 1660 tis to equal that at more money and power. Downside is AMD is only decent for cyoptonight and eth. May I know how much the GPU speed of your device is my friend? Do you do overclock your device? I think it will increase your income in mining, with the consideration of saving electricity or not if you do overclocking your device. Its over clocked at 1800 mhz running 2800 on xmr at less then 200 watts per card. I was running some quick numbers 1660 ti vs Radeon VII $ per hash and watt per hash are very close. Advantage of the Radeon VII is it might retain its value better then the 1660s similar to a 1080ti? |

What about a Radeon VII? Very efficient and might retain its value better, similar to a 1080 ti.

Yes, you are right,
Nvidia GPU 1600 series is better than others,
my friend has used the 1600 series Nvidia GPU for the miner's client, he also used GPU 1660ti and the results were unsatisfactory because GPU 166ti didn't support the miner's client, my friend was disappointed to have bought 1660ti.
if anyone doubts I suggest buying the 1600 Nvidia GPU series to prove it yourself. in my opinion, we are very fortunate to buy it because many miner clients support the 1600 Nvidia GPU series.
I don't know about your friend's friends, but my 1660 Ti's mine just fine thank you very much! I have both 1660 and the 1600tis and they are very close in performance. The ti seems like it might be more future proof with faster memory. |

RX sires cards do not look too bad for progpow https://progpow.pro/. Looks like a 580 can get 80% of the performance of a 1070 for less then 1/2 the price. RX 570 = 11.23 1070 = 13.3 That's at default clock with default power draw. The card will draw roughly 200-230W while mining, so it is pointless. Undervolting it down to 1150-1200 core should achieve nearly half the power draw. I think the power you use to do mining is very high, imagine if you have a lot of cards then the power you need is very large and not profitable. Webpage says the power draw is 135 watts. I have 80 GPUS and I run them at 70% and make a decent profit at .042 cents KWH. |
