Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[adaseb]

reinstalled Windows with rx480, switch to calculate in radeon drivers, add arguments to claymore specified -strap 1 -rxboost 1 in Nicehash miner ---- everything is as it was before, but claymore did not accept these arguments and gives 24 mx.

Can you tell me what the problem is?

I had this issue before. Basically if your clock rates are properly set (memory clock at least 2000mhz) then your issue is that most likely you need to manually mod your bios. For me it was hit or miss with the "-strap 1" command, on some rigs it worked while on others I couldnt get it to work, got a low hashrate and just manually modded the straps with the bios.

Try that and then run it with and without the strap command, if you are still getting the slow speed then download a different version of AMD drivers, sometimes the latest ones can be buggy. And make sure your core clock is at least 1100mhz or so. Make sure its not stuck at 700mhz or so.

I had the exact same issue but with Ubuntu, for some reason Claymore 15 doesn't work anymore with my 4GB cards. With Windows it stopped working even earlier than that. Which is a shame because I liked Claymore with the remote manager and stability and all. However Phoenix pretty much seems to do everything Claymore can, the commands might be slightly different but the features are the same.

Thanks for repply. Sad for Claymore, i liked Claymore a lot. So, do you know the "-rxboost" equivalence in Phoenix? im lost about 4K Mhz for each card without this command on phoenix... :/ (i dont use OC)

You should use AMD Memory Tweak (https://github.com/Eliovp/amdmemorytweak binaries are here compiled by me for those who don't know how to compile the source: https://drive.google.com/open?id=1sgYugFgFq5Ja89DexDvwgvP1dtRO2d7A) and you will 100% sure get 1.0%-1.5% more hashrate than Claymore.

Unzip WinAMDTweak.zip to some folder XXX. Run Claymore with your best settings on epoch 300 (EthDcrMiner64.exe ... -benchmark 300 ...). After that run a command prompt window with Administrative privileges ('Run as Administrator'), navigate to WinAMDTweak.zip unzipped folder XXX using 'cd XXX' command and after that run:

WinAMDTweak.exe --current



You will see the current memory setting of Claymore. Something like this:

Copy/Paste them down in text file.
After that stop Claymore. Run WinAMDTweak.exe --...  with these settings and run Phoenixminer.exe after that with the  same -cclock -mclock -cvddc -mvddc parameters like Claymore.

For Nvidia use PM 5.1 with -straps option.

Having dag issues with 2x AMD RX 580 8Gb cards with the latest Claymore ver. 15. Windows 10 is using around 3.6Gb total when mining then when it creates the dag which is a additional 4.0Gb it pushes it over 8Gb so therefor the AMD 8Gb cards can no longer mine ETH though NiceHash which was what I was doing until my computer crashed so bad I had to reinstall Windows 10... Long story short The Claymore Developer needs to update Claymore to support a total of 8Gb GPU with the GPUs on a little under half load. I've took countless steps to try and remidey the problem but no such luck... That includes uninstalling the latest version of NiceHash Installing again, reinstall diffrent versions of NiceHash, Set my Virtual Mem to 30000 and uninstalling and reinstalling diffrent versions of the AMD Drivers starting with 19.7.5, 19.10.2/3 and 19.12.3. Still same outcome, Can not create big dag for GPU openCL error and tells me to restart miner which I have also done countless timesiss.

You must change Miner Software , switch to Phoenix miner that work weel and have very similar setting ..

The problem si that Clyamore is too long times not updated so do not work with actual DAG dimension .. s not your problem is a claymore problem ..

I already tried with Phoenix miner but there is a problem. With 5.0e start mining but very often it`s restart itself (just the miner software). With 5.1c version after 20-30 minutes it`s appear message Phenixminer exe stopped working. With the oldest versions is same like claymore. Any idea? Thanks

i check PhoenixMiner 5.1c in win10 and it is ok until #379 epoch (4GB DAG size)
now just work to mine ETH at #368 epoch and stop mining ETC because DAG size is bigger.
any other suggestion?

[polkovnik27]

hi, please advise - i have 2ea-4gb -mine Joys and 2ea-8gb -mine ETH card in one rig. when i run two miner windows of claymore - i have different hashrate , it depends on wich miner run first - first window show me 30Mh from 1 card . Second window have about half hashrate - 20-23Mh from 1 card.
how to run two miner windows with different coins with full hashrate (about 30Mh per card) ?
Win 10 , 19.4.2

There is a miner called lolminer and it figured out a way to mine past 4GB with reduced hashrate. It's somewhere in the Bitcointalk mining section. From what I recall it's available for both windows and Linux.

Way it works is that it slowly reduces the mining speed after each new DAG and on like 4.2Gb it loses like 70% of the hashrate but you don't have to worry about this until March 2021, by then you should just switch out all your GPUs for >6Gb.

However for the first few DAGs past 4GB the speed is only slightly reduced.

Anyone seeing decreased performance with 1080 Ti now? 1070s have had reduced performance for a while, but 1080 Ti seemed to be hanging in there pretty strong with eth pill.  Now, I'm only getting 34-35 MH/s per card; down from 40.

Im at 36MH/s with a regular 1080 not TI. I am also using the straps and no ETH pill. Maybe try using the straps instead of the ETH pill.

still can not mine with 4GB cards?

You can mine but most likely not with Claymore and not under Windows. Easiest way is to just install Linux and use PhoenixMiner. It will work for another month or so. Then you need to switch out your GPUs. There is a workaround where you can use something called lolminer and when PhoenixMiner will no longer mine past the 4GB DAG you can use lolminer and it will work but at reduced speeds. At first it'll be 95% of regular speed and every new DAG it will slow down.

I think somewhere in March 2021 it will be around 4.2GB DAG and the speed will be like 70% reduced and not worth it. But for the first few dags past 4GB it will not be as noticiable. However right now ETH is not really that profitable as it was during the DeFI days.

any news about version update?

Claymore? Your miner is incredible old:((((

please help
My graphics card is ati amd redeon hd 5450

I use Windows 10 and the latest version of Claymore
My problem is that I can not mine and Claymore makes a mistake



gpu0 - not enough gpu memory to place DAG, YOU cannot mine this coin with this gpu
gpu0 - opencl error -61 - cannot allocate big buffer for DAG CHECK README.TXT
gpu0 failed
gpu0,opencl error -38 - cannot write buffer for dag

error -61 - cannot allocate big buffer for DAG CHECK README.TXT = Usually too small virtual memory
error -38 - cannot write buffer for dag = You dont have enought VRAM on your card, you need more than 4gb

And basicly your card is too old for mining

[miner29]

Linux doesnt suffer from this issue...running claymore on 4gb on eth currently.

[minefarmbuy]

I have 580 8GB, 1070 ti, 1080ti  on windows with no issues. 1080 ti is just under 39 mh/s. I tried phoenixminer and wasn't stable at all on my system and had lower hashrate than claymore on the green cards but increased on 580.
