Wait until 370 epoch, you will change your mind.

Kawpow works on 4GB still but i thin kthat profitability will be killed when all those 4GB or 50% of them will switch to  Kawpow ... good luck with profitability.

In smos it should work until 385 epoch Thats the difference, Our SMOS linux does not use any graphical interface.
It is server like linux which can be managed via cloud dashboard.


Excellent answer !

Those Windows 10 rigs will stop working also (if they are 4GB)

I have created new thread with explanation why is this happening

https://bitcointalk.org/index.php?topic=5265702.0

Hello guys,


Every 4 days more and more of you guys will have bigger problems with 4GB GPUs.
Today there was another epoch in ethereum that increased size of the DAG file that is being loaded into GPU. 4GB GPUs are almost full !
[Short version]

Why is this happening ?
This file is right now 3.75GB in Ethereum and 3.84GB in Ethereum Classic.
The problem with claymore miner is that he did not released fix for the 4GB cards.
Also problem is seen in windows as windows is loading graphical interface in first GPU which already has almost full memory.
Every 3 days dag file increase and cause problem on 4GB cards.

How to fix it ?
Solution is simple, you just need Linux like Operating system and SimpleMining.net OS is the way to proceed.
Then under that operating system you just need to use teamredminer and then problem with 4GB GPUs will be solved but still not for long.
In November / December 2020 the file will exceed 4GB and those cards will stop mining Ethereum forever.

Also there is about 20-30% GPUs that have 4GB memory so you can expect 20-30% difficulty drop somewere in November/December 2020 or maybe this will be smoother as Windows users will probably give up mining.

Anyway if you would like to fix your problem, the solution is simple

Here is whole email that i addressed to SimpleMining.net OS users: (with complete info how to fix it)
--------------------------------
[long version]
Quick but very important information about mining on 4GB GPUs.
Many users don't know but 4GB GPUs will soon stop be able to mine Ethereum (ETH) and Ethereum Classic (ETC)!
When you are creating new rig, be sure not to buy 4GB cards anymore. Choose those with 8GB or more.

Why is this happening ?
Well, there is the thing called "DAG size" in Ethereum. This is file that is being loaded into each GPU.
This file size is currently 3.74GB. And you are thinking right, when it grows to ~4GB the GPU will not be able to mine ETH.
On the other hand ETC (Ethereum Classic) has even bigger DAG file of 3,84GB so mining for it will end up sooner.

You will have problems sooner !
90% of users are currently using old good Claymore-ETH miner. But we are getting more and more signals that problems appearing right now in Claymore and Phoenixminer.
Windows user are doomed even faster with 4GB cards but you are using SimpleMining.net OS which is based on linux that handles mining much better.
ETH DAG file will exceed 4GB size in November/December 2020 and that might be last days with 4GB GPUs.
There are other coins which you can check on whattomine.com calculator but it will be less and less profitable.

How can i extend ETH mining on my 4GB GPUs ?
You should use miner program that addressed 4GB problem and made improvements so that 4GB cards could last as long as it is possible.
We advice switching from Claymore and PhoenixMiner to TeamRedMiner which fix works the best on 4GB GPUs.
Also its good to tell that TeamRedMiner has lowest dev fee and slightly better hashrate.
Still you need to know one important thing. When you look into dashboard hashrate, we are presenting you hashrate that miner tells us.
So looking at hashrate in miner/dashboard is not the smartest move.
If you want to be sure that miner program is hashing faster, you can verify that in much better way.
Take a look into your pool statistics website for accepted/current hashrate(real one) and not reported hashrate (what miner reports).

How to migrate from Claymore/Phoenix/others to TeamRedMiner ?
Edit your ETH mining group (or much safer - create new Config Group) -> Press "Change Miner" button - > search for teamredminer -> select USE on newest version
If you created new group, assign this group to your rigs.
In config option write those options:
-a ethash -o stratum+tcp://POOL:PORT -u 0x222222222.$rigName -p x --api_listen --watchdog_script
Or if it is SSL port then:
-a ethash -o stratum+ssl://POOL:PORT -u 0x222222222.$rigName -p x --api_listen --watchdog_script

Example config for TeamRedMiner for pools: (replace x2222222 with your ETH wallet address)
-a ethash -o stratum+ssl://eu1.ethermine.org:5555 -u 0x2222222.$rigName -p x --api_listen --watchdog_script
Example for nanopool:
-a ethash -o stratum+ssl://eth-eu1.nanopool.org:9433 -u 0x2222222.$rigName -p x --api_listen --watchdog_script

If anyone has problem with 4GB AMD GPUs stopped working under claymore miner then you just need to use teamredminer program and it works fine under 4GB GPUs.

OK guys, this is little advertisement but i have solution for you guys regarding today problem with 4GB GPUs ....

SimpleMining.net and choosing miner called teamredminer is the solution. Under that setup mining with 4GB cards works fine.
https://bitcointalk.org/index.php?topic=1541084.0

Yes. claymore should upgrade his miner to fix those 4GB problem.
But there are other miners on which 4GB cards are still working under SimpleMining OS.

Regarding windows, the main problem is that windows has graphical interface which allocates some memory in gpu.
Linux can be hadless and does not have this problem so putting 8GB makes sense only in windows.
Yet you can try in claymore using some options that load dag slower or uses different kernel.

Please guys try checking how it will perform under SimpleMining.net Operating System.

Update:
- Added link to calculator for checking how profitable is mining. The button is next to Tags button.

Miners update:
- phoenixminer-v5.1b (tomorrow we will add 5.1c also)

1050TI 4GB ?
DAG size in ETH is killing more and more GPUs.
Just to verify, please be sure you are using newest phoenixminer as it has some tweaks to let those 4GB cards mining little longer.

Please write to us at admin@simplemining.net again
We will check your rig and let you know what is wrong.
Please write in english

BIG changes are coming….
[/color]You as client probably spotted that we released very little dashboard updates recently.
You are right ! This is due to fact that we are working on something new.
Currently past 3 months our server side software is being rewritten from ground zero and this process will take another ~3 months. Here is some changes:
- we will finally release REST API for users
- we will introduce new Dashboard written in latest technologies (React JS)
- with first new Dashboard update we will introduce few changes and improvements that You will love
- Dashboard will be more responsive and with later updates will be lightning fast
- we are also working on native iOS app and if it will be hot then also Android app too !
- After everything will settle down, new features, changes, improvements will be added much faster !
- I am sure that You and other users will love upcoming changes (at least i hope so )

Update v1281:
- NEW added memory undervolting (mvdd) for RX5700 (NAVI). GPUs default voltage is 1350mv and undervolting to 1280 or 1300 helps lowering mem temperature by even 5*C on memory chip. The wattage savings are like 1-2W per GPU (new field is available in OC window)
- NEW you can now overclock NAVI RX5700 cards with higher memory clocks and also lower core voltage than GPU bios allows.
- improved sending debug console
- improved progress bar of downloading miner
- fixed nbminer stats (not summing hashrate)
- fixed issue with not always miner stopped after getting pause command and message cleanup
- fixed ugly messages on external monitor during first boot process
- fixed "there is no screen" flooded message on external monitor while miner in Pause mode

Yes, please send me email to admin@simplemining.net with details and rig name.
Please also leave the rig Online and we will check it.

Please write email to admin@simplemining.net - We will check your rigs.

NEW DISCORD is now officially available for you guys ! https://discord.gg/Ba2gHeP

Dashboard update:
- added new filter for searching rigs that have hashrate less than
- added example OC settings button in OC window - so that new users would know what should they put there

Rig Update v1280
-fixed teamredminer API. Now it shows speed values for each GPU but we had bug for 1 day that whole rig value was in kH/s instead of Mh/s so on rig stats you will see kH/s and in separate GPUs you will see MH/s. This is fixed now

BETA OS image
- we fixed problem on VEGA that hashing speed was a lot worse. Now the new image is added in Advanced commands. Generally it works more less the same as 19.50 drivers on vega. And older nvidia or amd gpus could work more less the same but not faster. SM-5.0.21-17-a20.10-n440.82-v1279.img.xz

Update - NEW BETA IMAGE
- released new BETA image with newest 20.10 AMD drivers and NVIDIA 440.84 that may have finally good performance on ALL GPU cards (i guess we will find out in users tests )
- this image should have better mining speeds on VEGA / Radeon VII / NAVI (RX5700 series)
- image contain also fix for popular e1000 network driver that could cause whole network failure due to packet flooding (in past two years there were cases like this, please let me know if this fixes this problem)
- be sure to use miners that support this 20.10 AMD drivers (phoenix 5.0), because on older versions the performance will be worse !
- note that you can easily reflash your rig from dashboard ( select one rig on rigList -> Actions -> Advanced Commands ->  OS reflash - NEW BETA )
