Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 1363. (Read 6590565 times)

I was able to use the latest version of Crimson 16.3 with this mining program. By doing so, I was able to go into Catalyst and manually change the fan speed. I could not do that in this mining program, as it kept crashing the program. Also, the program does not like it when you adjust mclock through it, although I can do that  "normally" in Catalyst without crashing my cards. Leaving it at the factory settings still resulted in the card producing the optimum MH/s when mining Ethereum. That was a plus, since overclocking creates all kinds of problem, as a general rule. The rejection rates are almost zero in this mining program, which is unbelievable. I brought the DCR intensity up to 50. It affected the Eth hashrate little. DCR hashrate, at this setting, is cooking away at 672 MH/s without damaging the Eth hashrate much. I will attempt to ramp up the intensity further once I have everything else set properly. Here is what I have for R9 290. Others seem to have differing success rates:


"EthDcrMiner64.exe -epool coinotron.com:3344 -ewal XXXXXXX.XXXXXXX -esm 2 -epsw XXXX -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal XXXXXXX.XXXXXXX -dpsw XXXX -allpools 1 -ethi 13 -dcri 50 -dcrt 5"

I changed -dcrt to 5, because the miner popped up failures due to get-work not happening fast enough, for some reason. Part of this may have been from using the non stratum access to suprnova, which I never knew existed. It may not be a problem now, but I left it in regardless.

This program is something else, I must say. I am curious as to whether there are other coin combinations out there which could benefit from this program, tweaked to the pairs and algos. Considering I have 3 Eth rigs here, this will boost daily revenues by around $8-$10, as long as DCR does not fall even more than it has recently.

Windows 10 works perfectly fine. Marvell1's problem sounds like power, excessive overclock, or similar.

Don't use win 10... problem solved

Maybe just try upgrading to a newer driver.

I'm using 16.3.1 on one PC and 16.3.2 on another and not had a single issue.

Could also be your cards are getting too hot or not enough power from your PSU.

So i tried moving some other machines over to dual mining and having alot of problems with the 3.2 version

several machines will just reboot them selves while mining the dual alogos, no error message nothing.  I wiped one machine with 6 290x cards back to stock windows 10 default drivers 15.300  ( always gets installed no matter what i do, even if i turn off network and mnually install 15.12 crimson when i check the device i see 15.300 /shurg  one machine with that same driver works fine in dual mode)


tried default intensity 30 and higer same deal machines just randomly die after about 10 mins

any ideas ?

Ya, I see the same after switvhing to supernova stratum.  It caused the miner to constantly restart (with watchdog), so I've deleted my DAG files and having the miner regenerate them.  Not really sure if that will help or not...

No it's Actiontech as I have FIOS now Frontier 80/80MB connection.  Ok I found I needed to lower my intensity on my main gpu for my system.

-ethi 16,4

My 4GB 380x is my primary card and my 3GB 280x is my secondary but ethminer sees it the opposite direction. So lowering intensity to 4 reduced lag in my Windows and that lowered disconnects down quite a bit.  But still having a few just not as many now.  It hasn't effected the performance much either.


Now to the other I have this PC as a DMZ host with mininum security.  I rely on PC firewall for any real threats.  The only other thing I have is inbound packets scanning ports are dropped on the main ports that are scanned.

RPC - TCP Any -> 135   
Net_BIOS - TCP Any -> 139   
HTTPS - TCP Any -> 443   
MSFT_DS - TCP Any -> 445   
SSH - TCP Any -> 22   

and block ip fragments. So that should not affect anything. Response time on many test sites are 51-52 ms for latency.

do you have an Asus Router ? if yes, try without "AiProtection"

Seemed to be doing pretty good now.. BTW I get this intermittently.


right after this disconnect is when I will get 2 or 3 rejects at least..  How can I resolve this disconnect issue?

on windows 7 64bit you need system ram of 4gb, my rig with 2gb and 3gb can't mine until i upgraded it to 4gb..using ethminer

haven't tried system ram downgrade with this dual miner yet..

okay, thought i had something else to worry about. i have always heard ram didnt matter much but since this miner is diff from most, that post got me wondering. thx

(still having freezes with my r9 290, i think that setting a FIXED value for gpu clock (factory) will fix it, can anyone give an opinion on this? I have fixed BSOD forcing constant voltage and got the temp down to 86-87 with 100% fan. which i may reduce to 70% depending on the temp.. I am running a test with the other 3 cards r9 280x to see if it may be something else)

unless this software is different, thats false.

etereum needs as much system ram as it needs GPU ram, because the DAG is loaded on both. But it only needs one copy in the ram for every running instance (and the DAG is only ~1.4GB, so even 5 seperate ethminer instances would be ~7.1GB of RAM usage)

if you have all your cards running in te same instance of ethminer your RAM usage will only be 1.4Gb (size of the DAG)

Of course not, just make your virtual memory 8 to 16GB min and it will work.

so, my fifth card wont work with 8gb of ram?! sh , i did not know that...

Thanks! 

DCR rejects 1-2% at this pool.

EthDcrMiner64.exe -epool asia1.ethpool.org:3333 -ewal <> -epsw x -dpool stratum+tcp://mine.zpool.ca:5744 -dwal <> -dpsw c=BTC,decred

Yeah  i need try to use smile pools without stratum. But stratum should work too. Using the last version of claymore

what's you reject rate for DCR on this pool?
and, could you please post your full command when you use this pool? I've been toying around with it, but can't seem to get it working..

Thanks that made a difference btw can this Cannot parse JSON! be ignored?
