Ethereum GPU mining?

[RussianSensation]

I found this thread with post #232. I am looking at upgrading my main gaming rig while keeping AMD GPUs dedicated to 100% mining.

"At the wall with 90w power limit - that is 6x1080 ~ [138MH/sec for 6 cards]

https://bitcointalk.org/index.php?topic=1464999.msg15085267#msg15085267

The same guy says GTX1070 mines faster than a GTX1080 because GDDR5 has lower latency than GDDR5X. I am actually very interested in replacing my cards for gaming with 1070 SLI and mining on the side but so far I haven't seen any definitive numbers for GTX1070/1080.

Also found this that shows an abysmal 5MH/sec mining rate for a single GTX1080 under Windows 10:

" I have 2 gtx 1080 FE, i got windows 10 and ubuntu installed, at win 10 i get about 10 mhash/s in ubuntu about 45mhash/s, i compiled the genoil miner using default settings as specified on github"

If anyone finds concrete MH/sec data on GTX1070/1080 mining under Windows 7/8/10, please post it here!

ok I decided to buy 3x 7970 ( or maybe 280x).Is this PSU good ?

290 does this speed with -45% power limit and 800mhz clock (voltage -100 MSI AB limit). I guess the power consumption wouldn't be much more than that of 1070 based on my temps 68 down from 86 at stock.
VRM constroller reports less than 80W in AIDA64 down from 150 at stock.

Interesting. The 1070 should be slightly better than a Nano for mining (and better for gaming / resale value) at least on Linux on launch. Too bad they'll cost 500+ CAD each but if the price of Nano's don't drop soon it could be the best card to get if you want a dual purpose gaming / mining card. Well unless Polaris surprises everyone at almost half the price

Indeed the 290's can be severely undervolted and underclocked for huge power savings if you live in power cost prohibitive area, else you're better off just mining at 30/31Mh given the price of ether. Plus at $200 they're a much better value for dedicated ether mining than a 1070/1080/Nano and will ROI much quicker. Given the expected difficulty curve and plans for Proof of Stake for late 2016 / early 2017 you have to think strategically here when making these purchases. The wildcard here is the Polaris 480 which may end up being the best card to invest in given initial price and the resale value after ROI is met.

Hopefully we all get results of that card soon!

Ya, I get it that for ether mining Hawaii and even Polaris 10 will likely be better than a 1070 in MH/per $ and overall MH/sec max throughput. My point is I already have 3x Hawaii cards in my main system and I will also build several separate RX 480 mining systems. At the same time, I also want to shift my Hawaii cards into a dedicated mining rig and replace them with GTX 1070 SLI that I can use as a dual-purpose mining + gaming system. I just need a confirmation that GTX1070 can at least hit 20MH/sec in Windows 7/8/10. If 1070s can mine at R9 380/970 rate, I am fine with that since they'll pay for half of themselves and then I'll just upgrade again in 2018.

You don't need 200 miners. To judge better accuracy you would need to be on a more populated mining pool with lots of miners like Dwarfpool. These pools have less swings due to volume so it's easier to judge in a shorter period of time.

Alternatively you need to run for a period of a few weeks to get a more accurate result. That's why I was hesitant to comment about Claymore when I first switched. Even with my hashing rates being relatively high I waited a few weeks before confirming it is in fact better than the stock miner.

Well I'm not gonna mess with dwarfpool so I can just keep an eye on my machines using Genoil and see how they fare. Though I may switch over to Claymore eventually if the remote admin feature proves to be too useful.

That's weird your hashing rates went down. Given the issues you have I would run a clean removal of the Radeon drivers using DDU in safe mode and then reinstall.

I uninstalled through the AMD driver manager software. If I have the time I can try messing with DDU as well, but I doubt that it'll change much. The behavior I got out of 16.6.1 is identical to every post-16.2.1 driver release AMD has launched thus far. And I am in Win10 (fast ring, 14361).

And thanks for testing Genoil out. Probably worth it for me to switch 1/3rd of my mining power of to it to see if it can keep up with Claymore. I hate paying that 1% even though I would totally charge the same if I had the chops to make something like Claymore

I don't really like paying the fee either. Even if Genoil's ethminer or the main fork can't match Claymore's alleged performance (and so far as I can tell, Genoil's fork can), I'm sure they can emulate some of the nicer features of Claymore's miner.

I just need a confirmation that GTX1070 can at least hit 20MH/sec in Windows 7/8/10.

I'd follow the Genoil ethminer thread, since the main point of that software is improved CUDA mining:

https://bitcointalk.org/index.php?topic=1368785.0

I think you need version 0.9.41-genoil-1.1.2 or later for GTX 1070/1080.

Also I just noticed 1.1.1 and later got rid of the DAG, interesting. Might have to look into that. I'm still on 1.0.8

Oh and I see Fury Nano's being cleared out for $499 CAD AR and Geforce 1070's are going for $620 CAD at NCIX?

Pretty awesome, thanks for sharing! Gah, 147 in one box blows my mind. Come on AMD release new hardware, I need to get my hashrate up! I might end up buying a Polaris 10 and an 11 just to get to 150 myself!

Sidenote ETH price is going crazy lately. I have been taking advantage and dumping all mine into BTC to hopefully take advantage of BTC prices jumping after the split. At $17 its going to be profitable to mine for a long time.

Thanks!

Yeah both ether and BTC are going up kind of crazy fast, panic buying before the split maybe. I wonder if BTC will breach the previous record from a few years ago? (ether already has).

Hopefully the split goes well next month!

 

[IEC]

WTF. Prices on BTC and ETH went bonkers recently.

Time to take some profits and funnel that into my GPU fund

$319 CAD for the same card Also the refurbs are back up to $249 from $229 CAD. Glad I bought last week

Great price at $209 USD new after rebate. That's worth building a 4 - 5 card rig with unless its only one rebate per household (but even at $239 new that's about as good as it'll get until Polaris).

Depends where you live but you'll likely need to sign up for an exchange and then sell the ether for whatever fiat applies to your country. After you have fiat you should be able to withdraw to your bank account.

You could also convert ether to BTC at shapeshift.io and then sell the BTC via locabitcoins, but I don't really recommend this method.

I know the CRA will look at the crypto to bank EFT transaction. They are classified as capital gain once it's withdraw to bank officially.

What if you withdraw and then send it back from the bank when the price is low to buy the crypto coin for example. How do you report it and have you done it before?

I feel like the CRA is double dipping since I can't claim the electricity cost as expense, and if I withdraw and have no way to classify the buy back cost when I exchange fiat with crypto coin, that sucks.

"I know the CRA will look at the crypto to bank EFT transaction. They are classified as capital gain once it's withdraw to bank officially."

Curious, how do you know this to be true?

What if you buy coins at say 1K but the market crashes and you want to get out. You sell for $600.00 and take the loss. If you then withdraw cash via EFT etc does the CRA still get a report that you owe capital gains? How would they even know without auditing the exchange that you lost money, or how would they know without auditing the exchange that you owe taxes?

What if you buy 100 ether at $24.00 each, withdraw the coins (as you should never leave more than a few coins on an exchange) but then you end up losing the coins somehow? What if the exchange gets hacked and the coins are stolen? or you lose your USB key containing the backup files and you have no other backup? or your house catches fire etc.).

Do you still report capital gains if those coins appreciate regardless of circumstance?

As you can see, it's not so simple when it comes to crypto and taxes and I think the laws are still being ironed out.

This is an important discussion but I think perhaps a little OT for this thread. One more reason to have a crypto currency forum area, wink wink moderators

There's a new stories a while back saying CRA will hunt for the Bitcoin trader , I think it's back when Bitcoin was making new high 2 years ago. Kind of scaring people to report the capital gain.

I am looking to exchange crypto to crypto, but already have an account to do withdrawal if needed. CRA only hunt for the peasants but slap the rich wrist. :sneaky: The scenario you listed is what I really wonder how the CRA classify them.

Wish you didnt show that to us, I ended up not waiting for the 480 and got two of these.

My bad, just wanted to help my fellow miners. I was considering one but I really want a 480 for gaming now.

Something I am finding really interesting.

According to my findings, the top A10-7850K APU with 900MHz core and 2400MHz doesn't get better than 2MH/s with Ethereum.

A10-7850K: 512 SPs

A8 7600 gets 2.1MH/s with 1029MHz core and 2133MHz memory.

A8 7600: 384 SPs

Ethereum must be entirely memory bound at some point, like with the APUs. Of course its not just memory bandwidth considering there's zero difference between A8 7600 and 7850K setups with different memory. Is it entirely due to latency at this point? The 8790M gets 2.9MH/s which is percentage-wise quite a lot better, even with 384SPs. The The A4-7300 is pretty cheap. I doubt that it'll get less hash rates. I wish AMD FM2 BTC board was still on sale so I can get A4-7300 instead. It'll be fun to see what benefits what. Also if it can go down to extra 10W when mining then 2MH/s will be adding to profits for few months(however small).

Yeah I've seen speculation that memory latency plays a big role. Maybe try increasing the timings on your system memory of the APU rigs to see if it hurts hashrate significantly?

 

[MrTeal]

Likely it's borderline on memory and compute. The Hawaii based cards seem to really be dependant one compute speed, while Tonga seems memory dependent.

It'll be interesting to see how Polaris shapes up, and how the 480 does relative to the 470. If it does have a memory bottleneck, the $150 470 might prove to be as effective as the bigger card.

 

[DrMrLordX]

I get 2.2 MH/s with my 7700k @ 1028 mhz iGPU and DDR3-2400. Same number of shaders as in a 7600. So makes sense.

 

[dark zero]

NVIDIA needed a massive OC and a die shrink to manage to reach the mining that a 28nm chip could do... seems that something is off, no?
