Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 903. (Read 6590718 times)

I am slowly trying to build a multi GPU ETH/DEC mining rig. I have my second RX 480 card in it and after adding the second card I get an OPEN CL hang error and one of the GPU idles down to a memory clock of 300 MHz and stops mining. I have added the flag and bat file for an automatic reboot but I would prefer to have this not happen at all. I downgraded drivers and it happens less often but it still happens. I set virtual memory to 24000MB. What types of things will cause this to happen and how can I prevent it in the future?

Dear all
i have this problem in R9 280x OC


Error Code 43

i try win7/8/10
i try 16.9.2/16.12/15.12
but no result

Well. Thank you!
I didnt read quite good the thread I suppose json format is good enough for me to locate weak GPU in the rig.
Actually i suspect one weard card in my rig and i'd like to know which is it in my identical 6*280x rig ( by the shares count).

Best Regards.

Here you can see all my messages:

Check this one:

This info can be useful only if miner is working for >100 hours, for shorter periods values will be almost random and you will think that something is bad with some card and ask why...
I will add it and I will refer to this message every time when someone asks me that question

Since yesterday I started to get also hang on OpenCL. And I have set virtual memory to 32000MB, so it should be far enough. Have no idea what is causing it. I am trying now the problematic GPU to run on higher stock voltages on core and mem to see if it helps.

+1. Asked before of this. No answer.

Here I have about 28,800mh/s in 4X RX480 8gb
Is there any way to improve this yield?

I didn't see if anyone posted a reply, but, as someone who is still running 380's here is my advice:

1) 380's run the best and are the most stable running 8.0 or 8.1 solo mining ETH. If you are dual mining then use 9.3

2) Save power by running these cards at around 800/1500. Experiment with undervolting.

3) For myself, the best dcri setting for these cards is around 20.

The R9 380(x) is a boring but very steady card. This card should run for weeks between power outages.

is there a way to mine ethereum dual mode with decred, and send the decred shares to nicehash, while i mine the ether directly with alpereum?

Can someone help me ?

I have Rigs with R9 280x 3GB / 290x 4GB and Rx 470 4GB

I mount a R9 280x and Rx 470 4GB, for configuration tests.

I have a problem, Mining with Claymore 9.3, I have more hashrate with a R9 280x than Rx 470.
What do I have to do this?

R9 - 25 Mh / s
RX-21 ~ 22 Mh / s

I have bought 240 risers and had 2 bad in the bunch.  I have bought half of them from MintCell with no issues.  If your board has a Gen1 or Gen2 setting, try that, and make sure you turn off the PCIe power saver feature under your power options.

If somebody can please explain to me over desktop screen share like teamview or skype how the hell to mine PAscal coin SOLO and in a pool ill appreciate it
I have tried to follow a web page but i can not get it to work, i dont understand what the hell am doing wrong.
I have been trying for the past 3 weeks.
Please help me

Claymore Dual Miner crashes on startup.
Im using Windows10 Pro and v9.3 of Claymore.
GPUs: RX580 with 17.4.x Driver.

Any solutions?

Miner v9.3

I have been using this miner for about 24 hours. I upgraded from 9.2.

I have 2 RX 480 with 8GB RAM. My issue is that over the past 24 hours my effective hash rate dropped 15 to 20% despite the fact that the reported hashrate is higher. What gives here?

I am using the ethermine.org pool.

Until this is fixed I am going back to v9.2

Yes, I would like to have that function too. Or number of shares in an hour, like GPU0 (or whole total rig sum)  20 shares / hour. Some pools does not show number of stale shares and the only way to count it is to get number of shares per last hour and compare it with pool report.

The truth is Hawkfish, myself, and MintCell are all selling the same risers.

Typically we're running less than 1% defective rate UNLESS something happens during shipping to damage them.  Or someone gets a bad batch.  Or quality from a vendor goes downhill. Notice how none of us sell "black" risers any more. They're rubbish. The build quality went really down hill so we all quit selling them.

A few things about risers and debugging them.

You did a great job by plugging in the cards direct to the mobo to test.

I'd also suggest using another spare riser to test but most new miners don't have a spare. (or start with 1 riser and see if that works.)

Don't plug in more than 1 riser per SATA power cable.  Just because a SATA power cable has 3 or 4 ports on it doesn't mean you should plug 3 or 4 risers in.  If you do you will overload it.  A SATA connection for a harddrive uses much less power than a PCIe riser.   Many people run 2 pcie risers per cable. That may work fine for you but I suggest 1 per cable if you can. You definitely don't want to try and chain 3 or 4 risers on one SATA cable. They won't be able to get enough power.

If you have the new blue (what I call server quality risers) then they can take the 6 pin PCIe power directly.

Double check your setup. Make sure everything is connected properly. Check that you put the little 1x card in the slot properly. Check that it isn't too loose. Check your USB, SATA, power etc.  When the rig is on check by touching the cables with your hands especially your molex/sata power. Make sure it isn't hot to the touch. That is definitely a bad sign.

Depending on your setup you may also need to change some BIOS settings.  Typically your motherboard BIOS is set to AUTO PCIe settings, but sometimes you need to change this to "gen 1" or "gen 2". That also may depend on whether or not you're running Windows or Ubuntu.  Try those too.

Finally, do you have enough power to run everything? Your PSU should run only at 80-90% capacity. Meaning if you have a 850 watt power supply you really want to run at 700-750 watts. You don't want to try and push it to 850 or 900 like some people do. That may work short term but won't work long term. Also if you're at say 820 solo mining and suddenly switch to dual mining... or make the intensity a lot higher... you can overload a power supply that ran fine for a long time.

A lot of people test their power with software tools that don't properly show the actual watt usage of the entire PC. I recommend using a kilowatt meter or amp meter. You plug the rig into this and plug this into the wall. Then you can tell the actual amount of power draw at the wall. Otherwise you're just guessing!  Right now my GPUz says this 280x on this computer is using 44 watts but I know in reality it's probably closer to 200watts. Just for the GPU. Not counting everything else in the computer drawing power.

Don't get me wrong. Bad risers do happen. But there is a lot of testing you can do before you get a replacement riser.

LOL. Was he really asking  about the Share accepted (ms)?  I thought he was saying no shares accepted for minutes at a time not talking about the latency.

As far as whether or not I understand what I'm talking about... I've installed and setup pool software. Have you?

You can use this to measure your power at the wall and show the costs after entering the price per kW/h.

I use 1160/920 and mem 2140/920 with dcri 32 on DCR ovb using my same bios. I get 29.4/942. I use claymore to set the clocks/mem/power no powerlimit increase needed, I use awesome miner to give me live conversion to $ and this setting give me the best $. all my Red devils are the same but your millage may vary

DCR if you don't have to pay for the electricity. If you have to pay yourself, even mining ETH in ETH-only mode will cost you double the profit here in germany.
