Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 568. (Read 6590757 times)

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

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.

Nothing, it just cured itself

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

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

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

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

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

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


Tried all the servers , any idea ?

Another problem - can't catch temps on amd chips. Tried GPU-Z, AB, Trixxx etc.

Same story here - just use afterburner for NVIDIA and Claymore for AMD

I've installed on AMD rig few Nvidia cards, all is fine but i can't control clocks/voltages via Afterburner/Trixxx on AMD cards, Nvidia clocks/voltages/fan control works. Already tried reinstall amd drivers. Win7 x64. Maybe someone have similar setup. Next step - i will try control via miner.

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.

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.

Nope. The blockchain driver is actually better in terms of power consumption. There're no spikes.
It seems either new power(?) optimizations by AMD introduced in 5x Polarises or some sort of a bug of Claymore miner.

Here's full system consumption ( asrock h110 pro btc+) with 4*570, just for the reference:

No need to do anything, they are ready. https://www.reddit.com/r/MyEtherWallet/comments/75xie3/is_mew_ready_for_byzantium/

My wallet was created through myetherwallet.com in december last year. I hold some ether in that wallet. Do I need to change anything?

I do this just fine, I use 0 for the nvidia cards, my first 8 are 570/580 and the last 3 are 1070s.  so it's like 1100,1100,1100,1100,1100,1100,1100,1100,0,0,0

1) I have noticed the same thing. I always have to start the miner, close it, and start it again for best speeds. (rx 580 gpus)
2) I get rate drops from 29 down to 20 and back up again...haven't noticed them staying at 20 here.

The only issue I have here is I have been getting gpus hanging, causing the miner to restart and my rig (sometimes) just up and restarting for no apparent reason. I assume right now that it has nothing to do with the miner and everything to do with the blockchain driver and my power supply running out of juice. As I've lowered cclock on each gpu, both the hanging and restarting have gotten better...to the point where I am almost stable now (I make small adjustments). If the blockchain driver is causing power spikes, that would definitely explain my issue.
