Topic: 1080Ti Specific - Best mining option - page 296. (Read 409677 times)

Lowering the power target does reduce the voltage.

I run 60-70% power target which is 150/175w. Anything more than that you are using a lot more power and heat for a small amount of hashing power.

For me I was running 60% power target 150w and doing 640 sol. @ 730-750 sol I bet you are pulling in 300w. Double the power for just 100 sol.

So guys, we still haven't decided what is currently the most profitable coin and algorithm for 1080Ti? Currently my setup looks like this:

miner: EWBF 0.3.4b,
mining algorithm: equihash,
average speed (1 card): 700-720 sol/s,
pool: equihash nicehash

My average profitability with EWBF miner with one 1080Ti is: 0,0020 BTC/day (reading taken from nicehash website), which translates to 5$/day. Seems kinda low to me...

I still haven't decided if it's more profitable to mine ZEC directly, deposit it to poloniex, trade it for BTC and then withdraw it back to bitcoin wallet. There is 0,15/0,25% sell fee on poloniex if you want to exchange ZEC for BTC and 0,01 % withdraw fee, if you want to withdraw BTC from your poloniex account to your BTC hardware wallet. So 0,26% fee is the highest fee you're going to pay if you trade your ZEC to BTC and then withdraw it to your BTC wallet on poloniex. Of course that is if you mine on pool without fee (like slush pool) and also excluding 2% dev fee for EWBF miner.

On the other hand nicehash has a total fee of about 4,16% (in my case). On pay day I had 0,0408828 BTC and payment fee was 0,00163531 BTC, so in the end I received 0,03924749 BTC to my bitcoin wallet, which translates to 4,16% payment fee. In case you are wondering 0,00163531 BTC is 4,1$, so I have to mine for nearly one day a week (with one card) just to pay for payment fee on nicehash. But what makes nicehash special is no worries about transferring coins between wallets, trading them and then withdrawing them back to your BTC wallet.

Your thoughts?

 

Can anyone recommend some good risers . I have several Ti 1080 and my motherboard can only handle 2, i want to add 2 more
I was thinking of this

https://www.amazon.com/6-Pack-PCI-E-Powered-Adapter-Extension/dp/B01N3UVJHM/ref=as_li_ss_tl?s=electronics&ie=UTF8&qid=1495977463&sr=1-2&keywords=USb+3.0+riser&linkCode=sl1&tag=mylifegadgets-20&linkId=afdaa25f5896e84ca1440e63528d3407

but the reviews are poor. Are there any other risers? And since my power supply is 1000 watts is that all i need?

16$/day on Skein is a dream. I'm trying ZEC from nanopool right now, its making about 5$ day with 1 1080ti, DGB is no longer a best option to 80ti when pass a treshold of 0.00000600BTC, above this we keep going on SKEIN. Now we can see a increase of DGB on market, but nothing so truthfull as ZEC, they have a stable price wich is very nice for us, making 5$ a day and have a warranty of high or medium price in comparison of BTC.
Now you must make a choice, start a bet on DGB (and pray to not fell to much untill you withdraw) or keep on ZEC and reduce your profit to keep your balance safe.

Hi all,

I'm trying to divesify my rigs as I have 50+ 1060 and 12 RX.
I'm thinking on building some 1080ti's rigs and I wanted some feedback:
What is the hashrate on Skein: 1000Mh/s? How much a day are you guys making on 1 card: is 16$/day still a thing?
Are you guys mining anything other than Skein?

Thanks

As I recall, the "official" TDP for the Hawaii cards was commonly 300 watts.

 My R9 290 cards have been pulling that much on a 24/7 basis (occasional outages for power failures or moving) for well over a year now.


 *TEMP* is the killer, though higher power tends to lead to higher temp if all other factors are equal.

Yeah, that's what I was thinking. It's more like 12/7 use. Was able to adjust the fan based on this - http://www.upubuntu.com/2015/05/how-to-controladjust-gpu-fan-speed-for.html

But now the wattage varies between 230-260. Is going over 250 watts semi-regularly OK for the card?

Do you guys only lowering the TDP for optimal efficiency? Or do you actually change the voltage? If so, how?

My settings now are:

TDP: 75%

Core: +130

Memory: +100

Fan speed: 70

Temperature is between 55-65 for 3 cards mining ZEC, 730-750 sol.

Not sure how to messaure the watt usage since the miner I use don't show it.

Not for mining.

You can also adjust PCI-E lanes in most BIOSes

One on every PCI slot? Won't the speed difference be a problem?

7 VGA

4.

Anyone?

Ok thanks for explaining. My mobo has:
-2x PCI-e 3.0 x1
-PCI-e 3.0 x4
-PCI-e 3.0 x16

How many 1080Ti can I connect?

Hi,

You have to use risers: http://mylifegadgets.com/USB30RISERS for the small slots.

Santa, you need to test your cards at 70,80,90,100 and beyond and see if the extra POWER consumption is WORTH the extra hash. In my experience 80 on MY cards is about the sweet spot.

 For skein, you want the alexis78 version of ccminer - I was seeing ballpark 500ish mhash/s on GTX 1070s as I recall (might have been on a 1080 though) - the ti should be a fair bit faster.

 83c is VERY HIGH for a 24/7 mining GPU (The old R9 Hawaii GPUs could handle that high a temp reliably, little else can), and your fan setting is very low - 50% on a MINING card is going to overheat and cause issues unless you're in a VERY COLD environment.
 Kick that fan up to at least 80%, or better yet put a fan profile into Afterburner that's all-in by 80C.

 $10/day for one card is probably dead, too many folks have jumped in over the last couple months with WAY too many cards + coins have had a drop the last week and change.
 It might come back, it might not, but it would take a large price jump on one of the major GPU mineable coins to bounce it back up to that level for more than a day or two.

Investing to 1080ti was like buying dgb or btc.

I'm getting some disappointing hash rates, can anyone guess why? I'm using this miner - https://github.com/tpruvot/ccminer - on Linux. With lyra2v2, I was getting 45 mhash with an intensity of 19, which seemed OK, but my system crashes after 2-3 hours of mining like this. Now mining with -i at 15, my mhash drops to 25. edit: setting -i to 18 seems to be going steady @ 50% fan/83c/190-220W/85%-90% volatile GPU-util = 50 MH/s. Better, but not $10/day better.

I tried skein, got about 340-345 mhash/s. still on the low end I think. What can I do? I've only ever overclocked on Windows before. And oh the coil whine on lyra...

How to run 4 GPU cards when the MSI Z270 SLI Plus only has 3 slots?
