Hey guys i have the same problem of one of GPU drops to 0.0Mhs and error comes GPU HANGS IN OPENCL call.

Let me tell you what i have tried to far.

Windows 10 - Both uefi and legacy
Tested all Claymore 6.4 to 9.3
Changed mobo from MSI z270 sli plus to Asus gaming pro z270
Changed risers v006a to v006c (molex powered to pcie powered risers)
Tried amd crimson 16.3 - 16.7 - 16.9.2 - 16.11 and even 17.2.1 - 17.4.3 using DDU
Virtual memory 16gb 32gb 40gb
even shorting the x1 pci pins
changing bios settings x16 gen1 or gen2 and to x1
used stock bios and modded bios, over voltage over power anything...
I have tried almost everything.

I am arrived to the point that its either bad GPU chips or bad mobos.

Waiting for a more reliable mobo like asrock pro btc or tb85 etc
After that, i'll sell these shitty rx 480 sapphire nitro +

If someone have found a solution to this OPENCL Hangout error, please post it here or make a new thread.

My conclusion so far is bad mobo or bad gpus. It's hardware issue.


Newbie here.  Any help appreciated.

Setting up my rig.  This worked yesterday for a 36 hour run

      - MSI Z170A Gaming M7
      - 1x Sapphire Nitro (no plus) 8G RX480  (rookie mistake slower memory)
      - 1x Asus Dual RX 480 8G
          BOTH GPUs mounted on mobo
      - windows 7 64bit
      - Claymore v 9.3
      - crimson v 17.4.3
      - firewall off


My config:

-epool USEast.Alpereum.ch:3002
-ewal (xxxxx)
-epsw x
-mode 1
-ethi 16
-tt 85
-asm 0
-wd 2
-benchmark
-fanmin 70

Ran great.  Just going for stability, not speed yet.  Both cards hashed around 24-25Mh/s

------------
Today the risers arrived. (MintCell v006)

Moved the the ASUS DUAL card to the riser.  Added a second ASUS DUAL card with riser.  Sapphire remained on mobo in PCIe slot.

Started Claymore.  All cards hashing about 24-25Mh/s

After 3 minutes of mining ATI driver crash.  One mining card stops mining.

Reboot.  Same behavior.

---------
Read the forums.  Tried to back off to the suggested v15.2 driver, but it would not run with my RX 480.  Settled on driver 16.11.5

Same behavior.

----------

Ran the rig with the Sapphire mounted in case and only 1 ASUS on riser.   This was stable.

-----------

Any ideas?  I have swapped risers to no avail.  I can run 2 cards stable, but adding the third causes a crash a few minutes into mining.

At the time of the crashes no cards are running super hot.  (60-70 C)

Thanks



To reduce variables I placed the two ASUS cards in the PCI-e slots on the mobo.  Tested it and had no problems.  This ruled out any bad cards.

Placed the cards BOTH on risers (no card on the mobo directly) and it failed within a few minutes of load.   Bad risers.

Anyone have a suggestion on good quality risers?

The powered risers are usually good.

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.



Hello mining community,

I would like to ask for some help. Recently bought a mining rig 6x RX 480

https://www.mindfactory.de/product_info.php/8GB-PowerColor-Radeon-RX-480-Red-Dragon-Aktiv-PCIe-3-0-x16--Retail-_1124443.html

I am using Biostar TB85 motherboard, 12 GB RAM, EVGA 1300w, 120ssd, intel celeron 2x2.8GHz, windows 10 64.


I have this problem. On minute after I start claymore miner hashrate on one card drop to 0 and I get report - GPU hangs in opencl call - Need to restart miner.

I am searching for solution for couple of days already.

- I tried different GPU drivers, if I try to install 17.3 or 17.4 crimson computer crash.

- Virtual memory is on 16GB.

- If I start a miner without this card which lost hashrate then same thing happen to other 5 cards, hashrate drop to 0 on all 5 cards.

- I reinstall windows and all drivers, still same issue

- I switch cables and cards, nothing positive happen.

- tried other miners, pools, old version of claymore miner..

- tried function -gser -eser

Tried probly everything i could find on google, still no solution. Not sure if that is specific problem of motherboard, graphic card? other parts are more or less standard mining parts and probly have nothing to do with that problem.

Hop someone can help or give any proposition what should I do or try.

Thank you

Best regards

It is because you did not set your virtual memory. Go into system, advanced settings and change virtual memory to 16000MB like the program tells you to do if you are mining on multiple cards. If you don't do that you get the Open CL hang error, the miner tries to restarts and it just hangs.

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.



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?
