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

[badboyilprimo]

Having a really strange problem , 4 of the miners suddenly stopped working and getting this error always no matter what server or setting

Code:

ETH: Stratum - Cannot connect to eu1-etc.ethermine.org:14444

Tried all the servers , any idea ?

Similar problem today. Could it be because of upcoming fork?

no idea to be honest i have 7 more miners with the same settings working without any problems

I had a problem with 2. Works fine now but expereienced this trouble for about 2-3 hours.

I have 2 issues with Claymore 10.0 (Win10, blockchain drivers, 6card rigs running 570 and 470 cards)

1) After initial rig start (i.e. after powering or resetting the whole rig) Claymore 10.0 runs with lower hashrates (for example about 23-25Mhs with 470/570 cards). After stoping the miner and re-run .bat, I getting normal rates (i.e. miner has to be restarted and operates as expected only after 2nd run, never from the first)

2) Unpredictable hashrate drop during mining for some cards in rig (usually 1 or 2 of them). Rate drops and keeps at 23-25. The only solution I found is to restart Claymore.


Any comments guys?

Same issue here...as mentioned 470's and 570's

Has anyone found a fix for this ?

I have as instructed tried the timeout and it does not work

Thanks in advance

did you do anything to fix it or it just worked ?

Nothing, it just cured itself

Are you talking about problem numbered 1 or numbered 2?
As to No.1 I was discussing with few people and they have similar problems, not solved. I am not worry too much as it happens only at first start.
But No.2 really makes me headache, because unpredictable.

I am having a # 1 issue....but

on #2 add if using the .bat file --tt 70 --fanmin 50

the reason is that the cards are throttling down due to temp

see if that helps

[opies32765]

anyone getting the BSOD blue screen on certain Rx570 with the blockchain driver and claymore 10 whenever you try and change any mem or voltage settings ?

It also says that there is a

"Thread stuck in device driver error"

Thanks

I have -tt 70 set (with no fanmin parameter). But I do not see any throttling via HWinfo - it shows same freqs for GPU and memory when hashrate goes down.

Put these in the config file:

-r 0
-minspeed <total expected hash rate>

by using those commands, miner will restart if it cannot reach X hashrate in 5 minutes.
this is tried and tested as per my experience.

I have asked some times bwfore but cannot see  an answer   
I am using Claymore  9.xx on my rigs.. Now I am wonder if 10 is full stable now?
I was using 9.xx with WattTool settings and mining Expanse because of Dag-problem
If switching to 10 should  I make settings in miner?
I need set  underclocking of core/ oc mem and undervolt both
Will it work?

Can ethereum still be mined after the hardfork? Or should I mine something different?

Yes and block rewards will be higher.

Yes, I've been using it for a couple of weeks and no problem so far

Use blockchain driver, that could solve your DAG issue

I need set  underclocking of core/ oc mem and undervolt both

some cards may not work, some guys here able to do it by using certain version of after burner.

Did something happen that hit CUDA mining particularly hard that last DAG change? The hashrate on the MSI GTX 1070 GAMING X in my gaming rig dropped almost 2Mh/s but the RX 480s were unaffected.

I have an issue with my 1070 Gaming X too.
Hashrate seems to remain the same, but effective hashrate is much lower.

Same situations here with Gigabyte 8 GB Gamings version, new or old. At +56 degrees they crash and memory errors, and noticed when lower is more rarely. memory oc 2150, or 2050 for new 1500 timing version.

For me the hangs and miner restarts was because undervolting too much gigabyte gamings. 850 for memory not liked, back to 900 seems better. less or no opencl hanged. not problems from driver or claymore, i think.

For those who experience OPENCL hang - guys, i recommend you to try lowering you cards temps. However this is kinda tricky with some cards. I will explain below

For my Gigabyte rx580 g1 4gb i experienced same problems - no overclocking at startup sometimes (also - try to delete afterburner profiles for this cards and apply overclocking via Claymore) and after 4-8 hrs mining - opencl error, claymore restart or system hang - especially day time when it gets warmer - so all hangups i got at day time.

The thing is - the card was undervolted and overclocked - no HWinfo errors or something, doing 29.5 mhs ETH and 64 LBC in dual mode, but still this error with opencl.
Then i checked the average temp during mining - it was about 73-75 degrees which is pretty high as i assumed. I have installed the 120-120 fan for additional cooling - but the RX580 series uses some smartass cooler management - so basically the card just lowered down it's fans RPM, keeping the same temp - about 73 degrees.

After some research - i have decided to go risky way and modify BIOS as no other means of controlling fan-temps  worked for me - even claymore temperature control was causing system hangs.

I have used SRBPOLARIS editor to make changes to GPU "Target temperature" settings - i have put 68 degrees here and flashed card. (No other fan settings affected the fan behavior)

After that, the card works perfectly fine for more than 72 hrs .

I think the card was heating up way too much due to Gigabyte ineffective cooling and stock fan settings  - especially memory chips, what caused driver reboot and overclocking reset.

For those who need help with this mod - contact me, also i can help with memshift mod.

hi, i want to ask
i have some gpu nvidia and amd rx
is there any way to only use my nvidia card for mining?
meanwhile i use my amd card for mine other coin
thanks

Yes, use -platform 2 command

Yes and block rewards will be higher.

Technically block rewards are lower but block times will be reduced too</pedantic>
