Ethereum GPU mining?

[PPLP_SMorse]

Hey guys, anyone know how much power will one gtx1070 draw mining Ethereum or ZCash?. Trying to figure out how many cards I can get to work with my current evga 750W PSU

90-120watts underclocked on the core and overclocked on the memory depending upon model and clocks.

I set my 1070's powerdraw to 75% in afterburner to prevent losing the max hashrate i could get from my 1070 (28.5Mh/s). 400Mhz memory OC micron chips.

Thanks, I should easily be able to run 4 of them with risers

Thanks, how are your MH/s and Sol/s with those settings?

Edit: just saw you pointed your MH/s. Sorry about that. Were you using the Claymore miner?

Yes it is claymore miner because it used less ram and i can see the temp too. Sol around 390-400 with 90% power draw.

Any Canucks here? Which exchange are you using to get fiat in and out?

 

[ozzy702]

For those of you in the U.S. who are mining and selling on the exchanges, what is your tax strategy? Are there any sites you can recommend? With coinbase's records being requested by the IRS I want to make sure I'm on the up and up and not looking at an audit down the road.

Obviously I want to minimize my tax burden so your input is greatly appreciated.

Those are excellent results. I wish there were 570s/580s in stock the last couple weeks. I picked up a bunch of 1060s and 1070s last week. After some tweaking I got the 1060's to hash at ~22Mh/s at 66% TDP (.85-.91V) and +700 mem. For 5 cards on a dual core machine, they pull 635W from the wall (~115W each).

The 1070s are hitting ~29Mh/s, 66% TDP (.75-.9V depending on card), +700 mem for Samsung cards (27.5Mh/s and +500 mem for Hynix cards). Haven't measured power draw yet but I imagine they're in the 150W range.

The above is dual mining ETH and SIA which probably lowers the ETH hash rate a bit. Over all they do decent but hash rate is down compared to the AMD 500 series.

I still think 1070's properly undervolted and overclocked slightly outperform 480 / 580's in performance per watt. But yeah, too bad 570 / 580 stock has dried up. At MSRP prices they're still probably the best cards for mining due to software support and BIOS modding capabilities. I bought this 570 with some left over NewEgg credit so I'm pretty happy with the results. I've maxed out my mining capabilities so unless I start selling my remaining 28nm cards to replace them with newer cards I can't do much. Problem is Hawaii / Fury cards are still turning a decent profit and since they've paid themselves off eons ago so it's hard to let them go.

I use QuadrigaCX. They're pretty reputable but getting validated can take a week or two (probably true of most exchanges these days). I used to use CAVirtex before they got bought out by Kracken.

I can't answer your question but I have the same question for Canadians. The problem I've run into is the handful of chartered accountants I've talked to have no idea how to deal with crypto currencies and taxes. Most of them have told me something different which is a bad sign.

Perhaps we need a list of modern accountants or tax companies that have dealt with crypto currencies.

Have you been able to make trades relatively easily?
How about putting in and taking out fiat? Painless?

Yes it is claymore miner because it used less ram and i can see the temp too. Sol around 390-400 with 90% power draw.

With your data, and current ETH price and difficulty vs current Zcash price and difficulty it seems to me that mining either of them gives similar profits. I'll have to do my own testing once I get all the cards running, but all things being equal I'll just mine ethereum directly into my wallet and avoid the exchanges.

Don't only limit TDP if you're doing that. Go Higher with the clock at the same time, in that case you're undervolting. I'm at 65% with 390-400 Sols.

If you're willing to accept 5% lower hash rate than at full speed you could achieve ~390-400 Sols and 28-29Mh/s @ 100W. In my country electricity price is high, so i prefer more efficiency.

So 4,5 GTX1070 should be ok with 750W.

Yupp i oced it while limiting tdp
My 1070 was originally for gaming, coincidentally it is awesomely efficient for mining now hehheh
1070 are too expensive at my place, so i got myself a 1060 to mine.
You guys should imagine the awesomeness of mining in third world country lol, I could buy a nice meal with just 4 hours mining lol!

Zcash's price went to Moon! RIP ETH ? Be ready for Massive attack on NV cards.I don't know I should buy GTX1060 or not (only for Zcash)

 

[DrMrLordX]

Heh, ETH is fine. ZEC and ETH roughly track one another now that ETH is implementing zk-SNARK. They'll trade blows all the way up to the top.

Tax strategy . . . we had some discussion about that earlier in the thread, so it might be worth it to go back a few pages and have a look-see. Bottom line is that you should expect to pay cap gains AT A MINIMUM. You can lower your cap gains exposure by holding your tokens for a year or longer.

I am happy about the current mining craze because I just sold my HD 7970 on EBay for ~$175 which I bought a couple of years ago on EBay for only $135. This presented a great opportunity to upgrade to a GTX 1080 which was on sale for ~$460 because it is a useless miner.

Yeah, I have an old Sapphire 7950 that's still mining ethereum on one of my PCs. I bought it during the lite coin craze when someone in this forum discovered a clearance batch at normal prices on some website.

Please continue to spread this information, so I can keep mining on NV cards on the cheap 😛

With the rise of Ether I'm also starting to wonder how best to go about this in regards to our Canadian taxes...

I haven't traded there in while but from what I recall it was relatively painless to get fiat money in and out, as well as buying and selling on the exchange.

That's where things get weird - for me anyway. I have coins that I have mined and coins that I purchased that are older than a year. However, I've been mining for over a year so I'll have to somehow go back in time, figure out the daily price, as well as the number of daily coins minted and then try to figure out the capital gains while accounting for the mining operation, subtract any expenses involved (hydro, mining equipment costs, etc.) as well as lost or stolen coins. I'll also have to account for downtime and capital losses. I'm probably forgetting other stuff but this stuff just makes my head spin thinking about it.

Outside of capital gains (I think in Canada the rules are you're supposed to pay 50% at a 33% tax rate, at least on short term investments...), there's also total income to worry about. There are some strategies I've heard such as investing into RRSP's and TSFA's (locking money into shor or long term savings, Canadian style) to reduce total income, but what if you put your money into an index fund that pays dividends etc...

Anway this topic of taxes could probably be a different thread altogether and I'm sure many of us have a target price they want to cash out a percentage of our earnings at, so it's probably going to keep coming up.

Anyone using 1060 FE rigs? care to comment on drivers, OS, coins, hash rates?

 

[VeryCharBroiled]

.. As i said, i run my systems for maximum stable overclock on several algorithms, not just one algorithm.

i do the opposite, i have my 470s tuned for eth, undervolted and underclocked core, overclocked memory with 1750 straps at 2000 or 2100 (samsung ram). easy on the power and can also dual mine sia or dcr with claymore. they run 28/29 on eth and some sia/dcr on the side so im happy enough.

i just mine eth and sia/dcr at nicehash. guess im too lazy to switch algos chasing the most profitable of the day bit. and as you say, different algos like different tweaks. seems too much of a compromise, but at the end of the day as long as there is profit..

stability above all. doesnt take much down time to kill profits.

90-120watts underclocked on the core and overclocked on the memory depending upon model and clocks.

What clocks and voltage are you running on your 1070s? Are you only mining ETH or running the Claymore dual miner? My 1060s undervolted to .8-.9V, core at ~1550-1600Mhz, and mem at +700 mine at ~110W. My 1070s are running similar clocks and voltages to the 1060s and I'm sure they draw more than 120W. That's dual mining.

I set my 1070's powerdraw to 75% in afterburner to prevent losing the max hashrate i could get from my 1070 (28.5Mh/s). 400Mhz memory OC micron chips.

I get very similar hashrates and power draw from my cards. I see some people claiming 30-31Mh/s for 1070s but I don't see how they got there unless Linux is that much more efficient than Win10 and Claymore.

Don't only limit TDP if you're doing that. Go Higher with the clock at the same time, in that case you're undervolting. I'm at 65% with 390-400 Sols.

Does limiting the TDP and overclocking the core actually make a difference over just limiting the TDP? Any adjustment I make to the TDP limit changes my core clock up and down so I wouldn't think overclocking the core along with limiting the TDP would have any effect.

If you're willing to accept 5% lower hash rate than at full speed you could achieve ~390-400 Sols and 28-29Mh/s @ 100W. In my country electricity price is high, so i prefer more efficiency.

So 4,5 GTX1070 should be ok with 750W.

Are you dual mining? My 5-GPU 1060 rig running a little Pentium dual core pulls 635W with all cards TDP limited and voltage around (.8-.9V). That's with dual bronze PSUs so maybe that's part of the reason why others show a lower power draw than my rigs.
