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

[mikeberserkr]

After restarting the error would loop. any suggestions?[/b]

You need videocard with 4 Gb RAM. 2 Gb not enough to create DAG file!!!

I am using QTminer successfully. That miner also creates dags

Claymore's miner create DAG in video memory. You have not enough to create. QTminer maby make DAG on HDD ?

What is the hash rate for Sapphire R9 Fury?

[adaseb]

By the way. 2GB GPUs still work when mining ETH.

to be honest I don't know....

the point im trying to make is... why is qtminer working and claymore isnt?
With the fact that qtminer has not been updated recently

i wanted to switch to claymore so bad but claymore is always giving me errors

hello,
 I am new to Ethereum mining and could use some help setting up my batch file please. I am mining Ethereum only  on Windows 10 with Claymore on a AMD RX480 8gb with the latest driver and I had it tuned for efficiency+performance and was getting 27mh and the rig ran very quietly. My problem is that I have added another exact same card and no matter what I try I am still getting 27 mh on the original card and only stock 24mh on the new one. Also the fans are really loud and the tweaks I have in the code aren't applying to the second card. I am using a 1000 W power supply. I have looked all over for sample code for multiple cards and haven't had any luck. Also the miner is only showing the temperate reading of one card.

Here is my original code for my batch file with one card:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal ##########################################.Nodge1 -epsw x -cclock 1050 -cvddc 920 -mclock 2200 -mvddc 900

Here is what the miner is reporting:
ETH - Total Speed: 51.725 Mh/s, Total Shares: 279, Rejected: 0, Time: 06:17
ETH: GPU0 26.936 Mh/s, GPU1 24.789 Mh/s
GPU0 t=69C fan=90%
ETH: 03/12/17-08:22:28 - New job from us1.ethermine.org:4444
ETH - Total Speed: 51.519 Mh/s, Total Shares: 279, Rejected: 0, Time: 06:18
ETH: GPU0 26.739 Mh/s, GPU1 24.780 Mh/s

The tweaked setting are not applying on the second card it is showing this in MSI Afterburner:
GPU1 Core Clock: 1050
GPU2 Core Clock: 1291
GPU1 Memory Clock: 2200
GPU2 Memory Clock: 2000

I can imagine that the voltages I would like aren't being applied as well.

Do I need to set up the second card as another worker and/or create a separate batch file for the second card?
I spent just about all day trying different code with the same results so any help is much appreciated.

Thank You,
Nodgeman

What is the hash rate for Sapphire R9 Fury?

R9 Fury is much more profitable to mine the ZCash. It cannot use the 4096 cores properly when mining ETH.

[Claymore]

It appears that 8.0 has a severe memory leak.  The miner reached 13GB of memory usage. This is no small leak that is a major leak. When it got that heavy it stopped sending out hashing power even though it was mining the remote manager said it had no hash power.

This is a well-known issue. Within a few days of launch Claymore released a new 8.0 which fixed the memory leak.

Perhaps he should have called it 8.01 or something so people would know that it fixed a problem.

It was ZEC miner v12.2, not this miner. ETH v8.0 miner has no known memory leaks and I did not release any updates for it. Though in 1-2 days I will release new version with Pascal support for NVidia and some other improvements.

[molitar]

The memory leak must have to do with PAS before I started to mine PAS I did not have the issue but at 13GB memory of usage when I have 16GB memory the miner kept mining but would not actually send out the hash data.  At that point I had to restart it. So probably in the PAS routine.

Glad to hear a new update will be released though soon.

Ask if someone has same issue, I don't see any memory leaks in ETH+Pascal mode.

Not seeing anything here however X windows can cause a memory leak that manifests like this, took me weeks to run it down months ago.. Some X configurations will attempt to buffer when you have X running on GPUs in some configurations, a separate console using another GPU, and it does exactly this... I found it circa 7.x and thought for sure Claymore had a leak so we sent some PMs back and forth but it turns out it was X.. I needed to disable some things to stop it from happening, don't have the specifics in front of me but I did write them down somewhere..

Claymore, I apologize for spreading misinformation.

I hadn't had enough coffee yet and got the two miners confused I deleted my original post so as not to confuse more people.

Hi. I have one issue with Claymore. He didn't work well with 2gb ram on matherboard, just shut down below creating dag file. And again and again that same, but when i put 4gb it work well and without any problams. Nicehash work fine with 2gb, so what i do wrong with Claymore miner or need some special config in BAT file for that?!? If some one know how fix it please tell me. Thank you.

Win 8.1
Claymore 7.4/8

I have 2 rigs mining ETH + PASC and have no issue with them... One of it has 400+ hours since it started mining, that's more than 2 weeks without restarting...

hello guys,
this week i bought 6 gpus XFX 480 8GB 1288 Mhz. i flashed all to 2080Mhz VRAM and change timing setting from 1775 to 2000Mhz .
2 of this 6 cards freeze on grey or black screen after 2-5 minutes, sometimes shows up artefacts. i change windows, amd drivers and claymore versions and  the problem still exists.
after that i take one of this card to test on another computer, i put it on pci-e x16 slot to test. on benchmark there isnt a problem. only when i start mining.
after that i change bios switch to default, without deleting drivers, the memory clock change to 2000 Mhz and performance change to 22-23 Mhz in claymore. and again freeze on grey or black screen after a couple of minutes. all pc crash until restart. i found that two of this cards are version 1.5. another cards are 2.3.
any idea what is the problem and where i make a mistake.
the benchmark on gaming there isnt a problem. are these cards has defective memory.

I think you might want to learn how to flash your cards' BIOS, i.e. set Memory Clock straps from 1500/1750 to 2000 MHz values. Check youtube, pretty simple.
I flashed Sapphire and Gigabyte and upped hashrate from 53 to ~58Mh and stable.

Plus check your AB if you set to change settings for both or just one card at the time. That little 'gpu' word and 'bricky icons'

my 2 cents.

I think it might be overheating issue due to overclock (1 or more cards can't handle your OC settings)

or

Your power supply is not enough. Tried/done down Core voltage of the cards with AB?

Hi, i just started mining with claymore. 5 RX480 red devils, and on of them keeps hashing low, i copy what im getting

ETH - Total Speed: 102.287 Mh/s, Total Shares: 139, Rejected: 0, Time: 01:35
ETH: GPU0 4.220 Mh/s, GPU1 24.774 Mh/s, GPU2 24.149 Mh/s, GPU3 24.665 Mh/s, GPU4 24.718 Mh/s

Can you guys help me and tell why getting that low hash rate

Thanks

I had same problem with simplemining Linux running Claymore.

I switched back to Win 10 no problems.

I had same problem with simplemining Linux running Claymore.

I switched back to Win 10 no problems.

Im running Win 10. Crimson 16.6 for drivers...

That GPU seems locked in core clock and memory clock, dont know why.

Im ticking with the settings of my cards, two of them i get it cool working, but when i apply the same settings to the others two i get

WATCHDOG: GPU 3 hangs in OpenCL call, exit o WATCHDOG: GPU 1 hangs in OpenCL call, exit

Can someone give tips on how to solve this two issues...
