end of ETH mining on 2G cards

[Rufsilf]

I bought the 2gb cards because back in February who knew it would remain profitable this long. And the 4gb were mostly overpriced.

You can use the 2GB cards for the ZCash mining. It will be mineable for very long term. You will get ROI.

I am pretty sure if he bought back in February he has already made ROI on those cards, probably 2-3 times over by now. I think it was close to 60-90 days back then to ROI on a full rig.

I had sold off most of my 2 GB cards on eBay but now I wish I hung on to them as you said, ZEC is making them quite profitable again.

My lone R7 370 4GB has paid for itself in ~5.5 months (earned it's first ETH mid-May, and the 14th in late September. The rest of the system, not so much.

Then you were here before I was. I gave my advices to people looking to do as us and start mining in June or July with kind of cards.

Same here. Now my farm is mostly made up of 2GB cards, I have one rig still hashing ETH and the rest on ZCash. Hopefully it stays profitable for awhile yet... I planned to be upgrading my cards/adding more this spring when people sell off gear after winter is over and when the new AMD cards come out.. Should be plenty of options on hardware, as long as there is a coin to mine at the time.

Is that still profitable now?

Depends on what cards you have and your electric cost. ZCash is dropping fast

Doesn't seem to have an effect yet. The difficulty is rising.

Does that account for the diff drop when ZEC was launched? Without looking at charts Id bet the ETH diff dropped a good bit with ZEC and this increase we see now isnt even close to what it was pre ZEC.

That is right.

The diff was around 104 on the ZEC launchdate. Now the diff is 94. (Around 10% lower today than on the 27th of october)

Yeah goes to show you what MASSIVE number of GPUs went online within the last month and a half.

The total hash of ZEC and ETH is much higher.

ZEC has basically been a "basket" coin for 2-3 weeks now - profitability close to ETH/ETC/XMR and generally shifts to even it out when any of the profitability parameters change as folks bounce hashpower around chasing the highest profit.

It's enough different from the other coins in the "basket" that you have to check on a card model basis though - my GTX 1070 RX 470 and R9 280x cards are currently quite a bit more profitable on it than on ETH, while the R9 290 cards have been enough of a tossup that I never bothered putting the time in to install Windows on those machines just to mine ZEC on them.

 Keep in mind that electric costs can affect profitability, as various combinations of miner card coin and tweaking can give different power draws.
 You have to crunch YOUR numbers with YOUR setup(s) not just assume that "one set of numbers fit all".

 GPU count in mining I'm quite certain started a large rise when the major ETH price rise turned it seriously profitable - but I suspect that folks are starting to have second thoughts about adding more cards/rigs as the profitability on ALL of the "basket" coins has dropped, between price drops and rising difficulty due to more hashrate being added.

I think the profitability is acutally low than ETH.

Early last week, my dual GTX 960 + single GTX 950 rig (all 2GB cards) finally gave up on mining ETH - some sort of memory error (I don't remember the exact details) and crashed Genoil.
 I'd forgotten those cards were still ON ETH.

 All of my 2GB AMD cards gave up on it a while ago.

 Seems like we reached the definitive "end of the line".

Thank goodness ZEC is still in the basket for my older AMD cards to work on - the GTX 950/960 though I restarted Nicehash for.

I recall reading somewhere that if you have a card with more vram in the same rig as those 2G cards, you could still mine ETH on them...

[QuintLeo]

I suspect it will become a real issue in a few months or so - and a lot of lower-end cards will move into ZEC or XMR or something where it's not an issue.

It's weeks, not months.

 As I posted that in november, and some of my 2 GB cards were still mining ETH into March, it was months - for those cards.

 Other cards turned out to be more like weeks.


 TheRider - the "in a rig with more than 2GB card" trick doesn't work any more, the actual DAG file now exceeds 2 GB.
 I had another GTX 950 mining eth in a rig with a pair of GTX 1070 (I don't think the 1070 comes in a version other than 8 GB - even the Gigabyte ITX version is an 8 GB card) - and it went "no more" a couple weeks or so back, probably at the same epoch as the triple-9xx rig packed it in on ETH.

Even though you can mine with them, the speed is much slower.

I was selling all my 2 GB cards as fast as I could in the second half of last year as I knew the DAG limit was coming, but ever since ZEC came out in late October I quit selling and put them back to work. I think I have made more in profit mining Zcash than I would have selling them anyway, so now I will probably just run them into the ground or toss them if/when ZEC mining with becomes unprofitable. All of them have paid for themselves multiple times already, and there seems to always be a new coin that you can squeeze some more profit out of.
