Title: end of ETH mining on 2G cards Post by: nerdralph on November 23, 2016, 07:04:34 PM Even though the DAG is still < 1.8GB, the lite DAG for on-GPU DAG generation takes up some extra space. Genoil and Claymore are both failing to allocate enough memory on a 2GB card I tested. I've thought about trying to tweak the kernel to free up a bit more memory, but I don't think it is worth it for a few more epochs. For the really desperate, you can probably still mine a bit longer with the official ethminer which uses DAG files.
edit: Swapped in a 4G card for the 2G, and although it has no problems allocating the DAG, it's hashing at half speed. Maybe I have an issue with the rig... edit2: rebooted, adjusted OC settings and now have a couple 4G R9 380 cards running smooth at 21Mh/s on 840/1500 clocks. Even if the issue is not the DAG size, we're not far from it. While the actual DAG size won't reach 2G until the new year, with the extra memory for kernel code, lite DAG, etc., I'd say 2016 is the last year for 2GB cards mining eth.

Currently works for me.

Currently works for me. Looks like you just cut/paste from somewhere, since the only GPU_SINGLE_ALLOC_PERCENT needs to be set for 2GB cards. Using another card with more memory is an interesting comment. I have 2 other 4GB cards in the same rig, and it doesn't make a difference. I could see how it might though, if the driver's crossfire support allows allocating RAM from another GPU, with DMA over the PCI-e bus. That would only be OK for the lite DAG due to the much lower bandwidth of the PCI-e bus. Title: Re: end of ETH mining on 2G cards (maybe just HW problem) Post by: maxmad_x on November 23, 2016, 08:18:41 PM Currently solution for all those who are having 2G cards will be to move to Zcash which has almost exactly same profitability as ETH. Sell ZEC and buy ETH for the same price :)
I am sorry this is not a technical advice from any point of view but a crappy solution to unfortunate miner buddies.

Sell ZEC and buy ETH for the same price :) I am sorry this is not a technical advice from any point of view but a crappy solution to unfortunate miner buddies. For R7 370 cards (2 or 4G), ZEC mining is better. They get only 13-14Mh mining eth, but 80+ sols mining ZEC. The R9 380 does better mining eth, and I don't expect that to change. The cards that are slow on eth mining like the 370 and the R9 280x will be used for ZEC. Cards like the Rx 480 will be used mostly for ETH, except for the occasional price pumps on ZEC that briefly make it more profitable to mine.

Those cards will be more profitable to mine the ZCash anyway. I have all my 7970, 7950 running the ZCash. Title: Re: end of ETH mining on 2G cards Post by: greaterninja on November 24, 2016, 10:28:23 AM I ran into this issue a 1-2 months ago.
The primary display video card needs to be greater than 2gb. I used 1 x 380 4gb The others can be 2gb. I used 5x 370 2gb. You also need to set the environment variables as posted above. I restarted that rig today to see if it would run into issues, its still hashing. The lifetime though...who knows. Zec is probably a better alternative for 370 as nerdalpha says. They are slightly different commands in linux and windows. Title: Re: end of ETH mining on 2G cards Post by: eckmar on November 24, 2016, 01:08:54 PM Umm i'm still mining with r9 380 2Gb each and they are doing just fine. There is no 4Gb card in the system but as i said no problem here. Looked at used memory, its 1870 on primary card
Title: Re: end of ETH mining on 2G cards Post by: greaterninja on November 24, 2016, 03:33:00 PM Umm i'm still mining with r9 380 2Gb each and they are doing just fine. There is no 4Gb card in the system but as i said no problem here. Looked at used memory, its 1870 on primary card I think it depends on the OS, driver, and how its configured. On my Ubuntu 14.04 LTS rig it allocates 200-300 MB for the primary video adapter unless I set it to headless mode. Title: Re: end of ETH mining on 2G cards Post by: adaseb on November 25, 2016, 05:15:57 AM Damn,
I restarted one of my rigs which were mining ETH for like the last 250 hours and the 2GB cards wouldn't work. Tried another rig, same thing. Tried a 3rd rig, and for some reason the Radeon 6990 still works. Its the only 2GB card working on ETH. So at the time of this post, it worked but since I never restarted that rig it kept hashing. :'( :'( :'( :'( :'( :'( :'( :'( :'( Title: Re: end of ETH mining on 2G cards Post by: paijoe on November 25, 2016, 05:39:26 AM few days ago I was frustrated

I have NOT run into this issue with the environment variables set. Yet. 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 IS kinda funny watching one of my HD 7750 cards with 1GB mining ZEC just fine - 44/sec isn't impressively scary but not bad for a card that paid for itself via LiteCoin mining years ago. [edit] it's even funnier watching one of my A10-7860K mining ZEC - at a whopping 11/sec with only 512 MB allocated to it. Not really WORTH enough to leave it that way but I decided to experiment in the hopes it would be closer to the HD 7750 on performance (same # cores, newer GCN version, but much slower RAM). Funny part - it's probably closer to making up the electric usage on it's GPU section than the 7750 is. Title: Re: end of ETH mining on 2G cards Post by: toptek on November 25, 2016, 02:32:51 PM set the environment variables
I don't set the environment variables with my R7 370's mining eth if i mine them, mostly i mine Zec but I had set them with my 7870 when i had it, if i wanted to mine ETH with that card and both cards have 2 gb, i guess Ive been lucky with the 370 . Title: Re: end of ETH mining on 2G cards Post by: nerdralph on November 26, 2016, 03:49:36 AM 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. It is impossible to allocate a 2GB DAG file on a 2GB card. Kernel code, OpenCL driver code to launch & control kernels, etc takes up memory. The light DAG (for on-GPU DAG generation) takes ~30MB as of the current epoch. https://github.com/Genoil/cpp-ethereum/blob/master/libethash-cl/ethash_cl_miner.cpp#L442 Genoil's miner could be modified to release the light dag buffer after the DAG is generated, but that would only help for a few more epochs. I don't think it is worth the trouble, and I'm pretty sure JW isn't going to bother either. I'll use my 2GB R7 370's for ZEC. I only have one 2GB R9 380, which isn't much better than a 370 for ZEC, so I'll just sell it.

Title: Re: end of ETH mining on 2G cards Post by: adaseb on November 27, 2016, 12:29:22 AM Another 2GB stopped working today when we got Epoch #90.
It works until you re-start your program. Title: Re: end of ETH mining on 2G cards Post by: QuintLeo on November 27, 2016, 05:27:32 AM I noticed a couple nights back I didn't have any of my 2GB cards in rigs I had gotten back online - and quickly fixed that.
Both of my single-card HD 7870 rigs DID work fine prior to the most recent epoch - but they were enough more profitable on ZEC that I slid them over to that and haven't looked back yet. Given the 2GB issue appears to be hitting NOW (I'd neglected to consider the other stuff that has to go into the card's RAM) I might just leave them there. I've also got my dual R9 280x rig on ZEC, as it's profitability ratio on ZEC/ETH is pretty much identical to the HD 7870 rigs - but that rig CAN go back as those are 3GB cards. Been a busy week since I pulled the "in-wall electric heaters" and wired 220 outlets to their wiring to run some of my A2s on - I've actually got some POWER available again! Title: Re: end of ETH mining on 2G cards Post by: adaseb on November 27, 2016, 07:05:32 AM Well I got them working again by running -eres 0.
It means it doesn't load the next 2 DAGs onto the memory, so I got 10 more days left of mining. With the official miner probably another few DAGs along the way but I guess its bye bye 2GB. Title: Re: end of ETH mining on 2G cards Post by: Redrose on November 27, 2016, 03:33:52 PM It was a sure thing to happen, though it's sad. What I hope for you guys is that you'll find those cards another use and for all people I met here and to whom I recommended to don't buy 2 Gb cards that they listened to me !
Title: Re: end of ETH mining on 2G cards Post by: adaseb on November 27, 2016, 06:43:45 PM I bought the 2gb cards because back in February who knew it would remain profitable this long. And the 4gb were mostly overpriced.

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.

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.

Title: Re: end of ETH mining on 2G cards Post by: QuintLeo on December 22, 2016, 12:26:33 AM 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'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".

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.

Title: Re: end of ETH mining on 2G cards Post by: Za1n on April 23, 2017, 03:35:17 AM 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.

Can you, please, explain in more details, what do you mean with "pair them"? Still trying to find out, hw to do this trick... Example1: you have 4 cards, 2 of 2Gb and 2 of 4Gb. Will they work? Does the slot position on the MB matter? Example2: you have 1 4Gb card and 3 2Gb. Will they work? Does the slot position matter? (read somewhere, that 4Gb card should be GPU0) Will be gratefull for answers :) Title: Re: end of ETH mining on 2G cards Post by: automobile on July 18, 2017, 09:39:52 PM I am still running my 2GB cards for eth You just have to pair them 1 to 1 with 4gb cards and use claymores miner I'm still getting 15MH/s out of my old 270's Hi.

I tried several times but got no luck. Thanks! Title: Re: end of ETH mining on 2G cards Post by: Undefined31415 on August 15, 2017, 05:49:36 AM Hi, is there any one successful with that trick? I tried several times but got no luck. Thanks! My gut says that you would be better off using your 2GB cards to mine Zcash or another crypto, and then converting it to Ethereum. Even after transaction fees, you'd likely make more than mining Ethereum with those cards directly.

Seems like he meant in order to have 2gb continue mining eth, we have to pair it with another 4gb gpu. Am I right? But I have no idea why it will work... Every single gpu mines separately actually... I'm also curious to know the workaround. |
