Ethereum GPU mining?

So just bit the bullet (slightly lost my mind) and bought a bunch of stuff off Newegg last night. NV build, based on existing numbers, should net around $1k/mo, ROI in 4/mo and some change. I'll try to do build pics when it all comes in.

I also built myself a NV comp for mining. 2x1070 +1080 all on powered risers on a cheapo AMD board. Bought the cards used.

curious what you pad for the NV cards used? Also I though 1080 was bad for mining due to G5X latencies or is that only for eth?

Looking at expanding my operation (8- rx480s, 1-290, 1 fury x) but obviously Polaris is impossible to find at msrp in reference form right now

1080 is doing fine for me, see above post. Expecting the same out of the TI's I just bought.

This is with nicehash btw, so it's picking the algos most appropriate for me. Right this second that appears to be Lbry algo, .28 GH/s.

Also, don't waste your time with ethminer. Try Claymore's dual miner or Genoil's fork of ethminer.

https://bitcointalk.org/index.php?topic=1433925.0

https://github.com/Genoil/cpp-ethereum

Both work, though Claymore has put a lot more work into his miner as of late. Genoil's fork is about a year old.

I'll take a look.

Does the claymore miner link have install instructions? I'm a complete newb when it come to this stuff.

I would recommend against Ethereum as Tahitis are no longer very good at it. You would be better off mining for ZEC and then selling it for ETH.

What's the problem with Tahiti's? Same basic layout as the 470/570, clock speeds a bit slower (1170 for mine) and the Tahiti front end isn't as advanced as Polaris. I thought these things mostly run on the SPs and last I saw they were all returning low to mid 20MH/s.

It's just binaries, unzip and run. However, you will need to modify start.bat, epools.txt and I think config.txt? dpools configuration file too if you dual mine.

Nothing wrong except for power consumption. Tahiti is extremely power hungry unless you undervolt/underclock it compared to polaris.

I paid ~$500CAD for the 1070s and $600 for the 1080. I saved about $100 per card on the 1070s and about $150 on the 1080 doing that, plus they all still have warranties so I was okay with it.
The 1080 doesn't do well at Eth IIRC, it does pretty well at ZEC. I'm running the 1070s at +100/+150/60% power, getting 430S/s and the 1080 is at +150/+250/70% power, getting 530S/s. According to EWBF miner, I'm hitting nearly 4Sol/watt on the 1070s and ~3.5Sol/watt on the 1080. The 1070s are at 52C loaded and the 1080 is at 65C loaded at 60% fan. This is basically a milk crate miner in a basement so all cards are constantly getting cool air. I try to run my cards as cool as possible while mining so I've stuck with those speeds, even if I could push more hashes out if I ran them hotter.
 
Do your 7970s still get 20MH/s? My 7990 is only getting 25.5MH/s right now, which is down considerably from last summer.

The Tahitis have a peculiar issue with ETH where as more of it was mined, this family of cards kept on losing hash rate. I remember when it was in early 2016 that a 7970 could do 20+ but as of now, they're closer to 12-13. At this low of a hash rate and with their power consumption, mining ETH directly isn't a good option.
 
For a beginner like me, one told me avoid Eth because they reached EOL, instead I went Zcash.Wrong move? I see Network difficulty went to crazy high! Please advice me.

If I do mining ETH, can I keep it for next year (or sell it on next year)?

I think it has to do with the 3GB of vram.

What does EOL mean?

Consult whattomine.com - that will give you a good idea of what is profitable for your card.

I see ethereum has dropped recently. I'm not worried, in fact I hope it leads to lower difficulty. I want to mine a lot of eth before it inevitably goes back up.

When Vega comes out, I think I'll buy one and mine using Vega and my RX480 at the same time. I won't run crossfire, just dual graphics for mining.
 
This is Friday and it just looks like some people are selling a bit to lock in profits. It doesn't look like much downward pressure, unless a big market manipulator decides to change the trend...

EOL means End of Life.i have 6x RX 480.Currently I'm doing Zcash.

I have 10 290x amongst my ethos rigs, Sapphire reference and Gigabyte Windforce. The Sapphire reference cards average about 25 Mh/s and the Gigabytes get about 26 Mh/s. What's the best settings/methods/clocks to achieve the highest Hashrate possible with these cards?
Click to expand...

Overclock/undervolt is the name of the game. Most of them can OC at least a little on -100 mV while mining ETH. My best 290s were doing 29 MH/s with -100 mV running the Genoil miner, though they still ran a little hot. That's one of the reasons I switched to ZEC 24/7 - lower heat production.

Definitely config.txt . The readme included in Claymore's mining software should describe everything in decent detail.

ZEC is certainly very profitable right now, and it does not (necessarily) have a planned end to the mining period, though there is a possibility that ZEC and ETH will merge at some point (or that ZEC will simply operate on the Ethereum blockchain). I'm sort of expecting one or the other. Plus now you have the ZEC forks . . .

I wanted to reply to this separately since many people who have mined out coins may have some concerns about the volatility of prices.

When you consider what happened to ETH shortly after the DAO hack (or worse, in Dec 2016), the current price fluctuations are of no great consequence. We had a "stable" price floor of around $120 less than a week ago, so I see no problem with ETH sitting at $160 now. Personally I wasn't expecting ETH to carry a price floor above $40 until after we went full PoS, so the current trends are . . . interesting indeed.

The main thing to remember is that Ethereum's value - and ETH along with it - are derived from the technology behind the entire concept. ETH is not meant to be a hypecoin. If people push its value higher than can be presently justified by the level of tech and support behind Ethereum, then it will inevitably drop. $204 (or higher) for ETH in May of 2017 just didn't make a lot of sense. Individual personalities (whales etc) may cause fluctuation around a certain point, but in the end, they can only push the value so low before people interested in the tech behind Ethereum pour their money in to buy at discounted prices.

Sure, it might trade at $325-$350 in June 2017, but why should it go up now?

It also seems like nearly every other crypto is getting bashed today. Monero, Stellar, and Ripple are doing okay-ish. BTC is down by quite a bit. Which is weird, since BTC SHOULD be experiencing gains right now (segwit etc)
 
Is it possible to underclock and/or undervolt Rx400/500 series cards for mining via software (AMD's own utility) or can it only be done via a BIOS mod?

Big news for Ethereum.

Oh dear. Ethereum basically doubled its market exposure (er well, ignoring all the Chinese citizens already trading in ETH via VPNs).

correction: maybe not. US GDP is ~$18 trillion. EU GDP is ~$16.7 trillion. China GDP is "only" ~$11.1 trillion. But post-debt, China has a lot more money to throw around than indicated by those numbers. It's still a big gain for Ethereum to be listed on a sanctioned Chinese exchange.
 
Allright , I got 144Mh/s With 6 RX 480 ( 4x XFX GTR , 2x Asus Strix Rog ) , all stock and Undervoltage up to 50mv for each card, Power Limit = 10% , Total power = 848w.

MSI Z97 Gaming ,Celeron G1840 , Kingmax 8GB DDR3 1600
 
I ran nicehash miner client, ethereum miner was there inside the program folder but doesn't show up on the nicehash client options, why is that?

Another thing I would like to ask, I'm using an ATX Z170 board which I got cheap last year when it was on sale. It has two PCI-E slots but doesn't support SLI. Currently I'm running one GTX1070, I wonder if I can add in RX470 4GB on the second slot to mine inside nicehash?

Will Vega be worth it in comparison to Polaris? Either way, I'm preordering Vega.
