Dear community,

we have gathered here today to regret the imminent end of 4G cards on Ethash.
Latest on DAG epoch 381 all of this precious GPUs will stop mining ETH.

Will they?

No!

lolMiner (https://bitcointalk.org/index.php?topic=4724735) made a release (https://github.com/Lolliedieb/lolMiner-releases/releases/tag/1.11) today that will allow to continue mining ETH with a slight time-memory trade of for some more weeks on top!
It even allows you to go on with ETC on Windows today and until they will swap to their new DAG scheme End of November.

Read this medium article to learn more and how to configure it:

Have fun mining!

Thanks for putting time into this, Much appreciated  :)

PS, the 580 came out in Apr '17 not 2005 like the pic but lol nonetheless

Fixed the image  ;D

Thanks, but I don't want to mine at 10-15 mh. If there are no new coins, then we are going to sell these video cards in December.

For people looking for consistent income I would sell the cards after they have stopped mining.

For people looking for maximum crypto gains I would sell the cards now to acquire maximum price for the cards and buy ETH on the next dip. 2 options for 2 different types of users.

Yea ... going on at lower speed is no option for all. But well for some it might be.

Consider: at this time the 4G ASICs of the first generation will have left the network. Also most of the 4G farms will be gone - I assume maybe 10 to 20% will use a miner support going on at lower speed.
That said: if currently 30% (just a guess) of the network are 4G devices, then suddenly 70 Th/s will be missing on the network. That would increase profitability of the remaining miners by over 35%. Given that keep using the code to continue mining for a 5-10 epochs more does not sound too bad, does it? Especially the first epochs will be nice.

Ofc that involves a huge crystal ball here. No one knows the exact numbers. Also some big farms will already have contracts to sell their cards / cleaning up the space for what ever will come after. But for some - especially home miners that are waiting for their RTX 3000 rigs to arrive ... well for those it might be an option.

teamredminer v0.7.14

This release wraps up our work for 4GB gpus mining ethash. Linux 4GB are verified to mine up to and including epoch 381 on drivers 18.50/19.30/19.50/20.10. After that, we have added support for extended mining from epoch 382 and up. Extended mining is a trade-off between hashrate and being able to mine at all, gpus will lose additional hashrate for every extra epoch. Please see the Linux section in the ETHASH_4GB_HOWTO.txt for more details and instructions.

Release notes:

Ethash: verified Linux support for 4GB gpus up to and including epoch 381.
Ethash: added support for extended 4GB mining from epoch 382 and up.
Kawpow: cleaned up false hw errs for some block heights.

Really wondering how this algo works exactly. At first I assumed that if you are mining looking for a share, and if your share is found on a difficulty less than required but the entire DAG is not loaded then your GPU won't see that share and it will lose it and hence why reduced hashrate.

So I assumed the way it works is that as long as your share difficulty is found somewhere in the 0-4096MB portion of the DAG then it will find it at the regular speed but if its in the latter then it won't see the share and skip it.

However if this was the case then if the DAG was 8GB then the hashrate loss should be 50% and not 78.8% on 4.2GB. Very puzzled how this all works.

You are right, other miners have already discussed this issue. In practice, this solution will extend the relevance of 4 GB video cards for another 1 month, and further mining Ethereum on them is useless.
By December there will be more information about new cards and hash rates, so I will probably sell 4 GB of video card

Are you saying rx580 4gig cards can't mine at 30MH/s again? That's a big lie, to keep mining with 4gig cards at that speed all you need to do is mix the card with a single rx 580 8gig card, make sure the card is in the first pcie slot of your Motherboard, I used claymore miner this way and it creates 8 gig dag from the first slot and mine away

you are using only one 8gb card on windows? with claymore? and the others cards with 4gb are working?

No. DAG must be allocated at every card VRAM. When you put an 8GB first, you only save a few VRAM MB from memory allocated by SO (Windows). SO uses more VRAM from first card, less for others. This is why to have an 8 GB at first position helps...

You guys looked into loading the additional dag size into RAM instead of discarding it? Obviously accessing RAM will be a huge hit, but should be better than nothing.

No RAM is not an option.  Speed would be near 0....   The speed needed must be either VRAM on board the gpu or HBM2.....not DRAMon the motherboard.

So, in the end, is it worth to buy now 4 GB cards. How little bit I followed, this is a long story and almost for a few years talks about leaving 4GB cards from the business.
I see here is a lot of 4GB mining hardware for sell, perhaps even cheap, just because it’s a little more complicated to do the setup.

what do you say, people, is the new investment in rigs with 4GB cards worth or it's so risky?

4 gig video cards have 58 days left to mine, if you take used video cards, then take a look at the models
Sapphire Nitro + RX 474/484
Sapphire Nitro RX 474/484
These video cards have a very high-quality cooling system that has been working for 4 years. All other manufacturers have broken fans.

I  will sell 4GB video cards and buy RX 5600

What will happen after 58 days? Can you explain me or point me to article about that?
I may be a little sceptical but when we talking about Ethereum network, there were many promises but mostly with a lot of delays.


I have some interesting offers to buy Sapphire pulse RX570 4GB.

The size of the DAG file will be the memory size of the video card and therefore the video cards will not be able to mine Ethereum with standard miners. Then you will have to use the solutions that are written above and get less profit with each new epoch.

Sapphire pulse RX570 4GB is good GPU. At what price do you want to buy them?

Just to note you guys: The miner got an update today (https://github.com/Lolliedieb/lolMiner-releases/releases/tag/1.12) that should fix the issues in Windows (first release produced defect shares).
Also there are more options to fine configure it now - the drivers especially on Windows seem to behave differently from version to version, so more introduced some fine tweak parameters to get it running (hopefully) ^^

is it worth torturing 4 GB? Maybe it's time to give them to gamers?  :D

Yes I agree however how you tried to sell any GPUs to gamers lately. It seems that if you are selling a RX 470/480/570/580 then almost every buyer that asks about it, says "Have you mined with this GPU?"?

You got no choice but to bite the bullet and just admit that you mined with it because if they check your other listings and see different models of RX series GPUs with different manufacteurs, they will be suspicious. If you were a gamer, why did you need 10 GPUs. Obviously they were mined with.

Most buyers don't care, they just want to make sure it works before hand and they give you the money and are happy. Other want to make sure that the fans are working at least. While others basically offer you "$20 because I know you mined with it" and lowball you.

In fact, there are no problems. I sold my RX 570 to gamers and they asked me if I was mining on this GPU. I answered yes, but I explained that mining is no more harmful than games. Because games have a temperature difference that destroys the GPU

hijacking this thread but anyone know why 1070ti 8Gb card have the same issue ?
I have tested in bench mode with height 390 and my mining speed is slashed by 2... (my motherboards also have 8Gb)

I can't remember which thread it was in (on of the more recent threads ie last 3 months) but somebody posted a link to the nvidia forums where a dev admitted it was an issue with a driver and that they had no plans to implement a change/fix to the issue. Oddly you don't see the same issue with the 1070Ti which is still hashing like new.

Damn if this how you remember, that would mean the end of 1070Ti passed 4Gb on ethereum if we can't find a driver that doesn't have this issue :-/
Hopefully this problem doesn't occur on Linux so at least we could migrate

I think this is the nvidia forum you are referencing : https://forums.developer.nvidia.com/t/blockchain-drivers/110847/12

I have a similar situation, after a few epochs I will not be able to mine with standard miners. The DAG file size will exceed the video card memory size by about 375 epoch

Thanks for the link. That's actually another thread but same information. Translation Lookaside Buffer (TLB) issue is known and nVidia really doesn't want to address the issue. That's another reason why I would be weary to buy nVidia cards for mining. They really don't want to support miners despite miners giving them record growth in 2017. AMD may not be catering to the miners with the new gen cards but at least they came out with the speed decrease workaround within 4 months.

Maybe they want miners to stop using the 10xx series and buy more modern video cards :)
On the 20xx series, I have not seen a hash rate drop when mining Ethereum.
I consider the 1070 to be the most successful video card from the 10xx series, because it is still relevant today and has a low power consumption.

Have you tried in bench mode with height 290 ?
In any case, i'm not buying nvidia for my next rig to replace my rigs once they are useless in a few weeks

I will probably buy 5600xt to replace my 480 4GB radeons. Nvidia video cards are very expensive and they are not yet well researched in mining. To avoid such a situation, it is better to purchase proven video cards.

Article about breakdowns of GeForce RTX 3090 and power supplies

For gamers the 1070 was probably the best of the 10xx series cards, but for miners the 1070 has been a dud. The 1060 6GB is now hashing about 20% slower for 45% less cost and the 1070Ti is still operating as it originally did. The 1080/1080Ti have only gotten better with age. The 1070 and the 3GB 1060 were the mining duds.

My 1070 video cards show 29-31 mh, for 4 years of mining the hashrate dropped by 1 mx on some cards - these are mainly cards with 8 pin power. Video cards with 8 + 6 pin power supply show 31 mh.
Now I don't want to figure out why the total hashrate of the farm fell by 3-4 mh.

1060 6GB show 22.5 mh
Good result after 4 years of mining.

No need to bury 4 gb cards just yet. ETh classic wil have dag size halved end of november. That means you'll be able to mine eve3n with 3 gb cards.
