Quick and dirty imprecise dual-mining assessment


#1

Spoiler: Probably not worth it anymore based on “realtime” revenue. Might be useful if you think secondary coins will grow faster than Ethereum

So I have my Octominer setup warming up with a pair of MSI RX 560 Aero ITX 4G OC cards. I figured I’d do some quick and dirty comparisons of mining revenue (based on a short but stable run of claymore 11.5 under ethos, values based on whattomine 25th March 2018 with zero energy cost).

Single-mining baseline: 27.745MH ($1.13/day)
ETH+DCR: 22MH (0.90) + 662MH (0.06) = $0.96/day
ETH+SIA: 16.589MH (0.68) + 496MH (0.01) = $0.69/day
ETH+LBC 21.937MH (0.90) + 61.334MH (0.02) = $0.92/day
ETH+XVG(B2S) 24.741MH (1.02) + 742.237MH (0.11) = $1.13

So based on my assessment, these are two generalizations I would make:

  1. If you have free power, you can diversify with Verge (XVG) and not lose revenue.
  2. If you don’t have free power, or if you dual-mine any of the other three currencies, you will lose out on revenue compared to single-mining.

The octominer isn’t on a power meter at the moment, so I can’t say how much more power it uses, but it seems safe to say it will use more, and thus will eat into your profits if you pay for power.

Obviously, if you do heavier tuning on the secondary coin you might get a bit more. And if you really desperately want to dual-mine, I’m obviously not saying you can’t. Just saying that it is probably not worth it based on this quick and dirty imprecise assessment.

Other data points and feedback welcome.

Edit: I tried keccak (smartcash) manually to adjust dcri.
ETH+KEC: 24MH (0.99) + 130MH (0.12) = $1.11

There’s probably a fair bit of tuning to be done, especially for siacoin (which dropped way down), but based on default behaviors in Ethos 1.3.0 with Claymore 11.5, the numbers above stand.


Low MH/s while mining? RX 580

nice writeup

yes, agree. you can definitely tune a lot more to get into a sweet spot.

I was doing eth+xvg for a while and if I go back to dual mine it’ll be xvg or xsh.

everyone loves free power!

I’d be curious to see what other folks are able to tune out of various cards. @allan5oh (I believe) said he was getting 185MH on Keccak dual-mining on a 580 for example, with no loss on Ethereum. I lost about 3MH on two 560s to get 130MH Keccak, as noted.

I would say the goal of this write-up is to provide an easy answer for people who think dual-mining is an easy button to dramatically (or even noticeably) increase revenue. It’s far from it.

If you’re willing to do the work, check for tuning, test various settings, and keep an eye on currency values, you can probably still make a bit. But most of the people who pop up and say “which coin should I dual-mine” probably won’t do the work or they would already have, well, done the work. :sunny:

i would like to point out that there is no such thing called free power. somebody will alway have to pay your electricity bill and you are either stealing from someone (parents or your employer) or someone made you a gift…


#5

I would like to point out that this is irrelevant to the conversation.

I think you should try adjusting your DCRI setting. I’m dual mining PASC and adjusted that setting so I don’t take a hit to my ETH MH/s at all, so I just get bonus PASC.

On a 7 card rig, I get about 210 MH/s ETH, and just under 1 PASC a day. It’s not a huge win, but the value of the coin is worth more than the power it draws, and I can still keep my fans under 60% and my temp under 70 C (that’s max for a couple cards; most are well below).

If the coin halves in value then it’s probably not worth it any more, but if it goes up in the future, then I win even more. I might just switch it over to BTC when I get a good amount, since the coin hasn’t been doing a whole lot lately.

Anyway, the point is that I think it’s (currently) worth it to dual mine if you put a little time into tweaking things.


#7

I would agree that it can be… but for most people asking, to be honest, they’re not willing to put any time in unless someone else does the work. :blush:

I’d welcome someone writing up dcri tuning instructions (and would add them to the original post if they like).


#8

It doesn’t really require much work. All I did was play with the dcri value using the +/- keys in claymore until my ETH hash rate wasn’t changing any more, and stuck that in my batch file for future use. I can’t remember off the top of my head what it was, but I think it was something like 11 or 12.

Dualmining with claymore also adds additional dev fee compared to single mining.
