Try set -rvram -1 on command line or in config, may be this can resolve your issue

Hi All. please tell me can I mine Ravencoin now or at the future with PhoenixMiner?
  Thanks.

I am in another country, I can't go home - Covid. So, I can't switch to the motherboard video and I am searching something to resolve the problem using remote control options...

Monitor card uses additional vram for OS. Switch monitor to the motherboard and should be fine

Is this what you're after Phoenix? Thanks for the prompt reply too!
I can Private message you a complete "log file" if you think it will help, but other than down the bottom where is says "Agent Service Error", I don't see anything abnormal. And as I say, everything is identical to the other 4 rigs, in every way. Please ignore the Maxhash pool below.. it was a test to see if it was an Ethermine issue.. but same result. Cheers.

Not a message like this. Everything looks ok in the beginning, but when it starts to change from epoch to epoch first gpu starts to mine with a lower speed and after a while the miner crash.
P.S. My monitor is on GPU 1... 

  Not yet, but we are preparing some Nvidia goodies in the next release, so stay tuned.


  We have tested with the same driver version and it works without issues. Please send us the log to assist you further. Probably the 4 GB card is used by Windows and doesn't have enough free VRAM. You have to either use an integrated GPU or put an 8 GB card as the primary adapter.



   The blockchain driver does not support the larger DAG buffer that is required for epoch 350 or later. Please upgrade to newer driver and remember to put all cards in Compute mode in the AMD Control Center.



   Please send us the log from the problem rig, we can't offer any sensible advice without the log. This shouldn't be happening especially when mining ETH, which is only at DAG epoch 340.


   We tried to reproduce the problem with the same driver version and the same pools but it works fine. Please check the page file size, it should be big enough for all the DAGs (roughly 4 GB for each GPU plus a few additional GB for Windows use).

pool swith trouble again. manual pool swith crash too

miner cash then switch back to main pool. lot of different rig crash on pool switch

Hi all. Can someone please try and point me in the right direction.
I have been running Phoenix Miner forever. I have 5 x identical mining rigs, each with MSI B360fpro MB, 8gb Ram, i3-8100 cpu and 10 x MSI RX 570 4gb gpu's, all mining ETH through Ethermine. All have been running sweet, then 1 rig stopped mining. I have checked all I can, stripped the rig back to a single gpu (and tried a few just in case).. the miner starts, but just will not hash. The miner screen shows it's trying, just looks like it's not attempting to build DAG? I've tried V5.0b, c and d. All same. I reformatted/reimaged (running PiMP, which has been/is awesome), copied and pasted the settings from one of the other stable rigs.. still same problem. I loaded "cough" claymore for testing purposes.. and it fired up right away, and has been hashing stable for the past 12hrs. It's got me puzzled, as I said, I have 4 other identical rigs running no issues? If Claymore runs, surely Phoenix should too?? The only thing left for me to do is assume its hardware and swap parts from a working rig.. 1 x 1.. painful.
Any thoughts would be appreciated.
Thanks in advance.

The fix for 4GB AMD cards doesn't work with 22.19.659.0/1 blockchain drivers (most possibly the problem is in these drivers, not in PM). Install other version after 18.1.1 and it will work. If you are with Windows 7, install Win 10 or Linux.

It's probably a driver issue
Go to: https://www.amd.com/en/support/graphics/radeon-400-series/radeon-rx-400-series/radeon-rx-470

And download the newest drivers, remember to uninstall the old driver with DDU to completely have old drivers deleted

Guys, could you help me. I got stuck when trying to start Phoenix miner. My last lines from the log are:


And here Windows is saying that the program stopped working and it's closing it.
I tried 5.0b and 5.0e - same.

The cards are RX470 4GB Sapphire Nitro.
Maybe it's the driver? It's old, but working with Claymore: 22.19.659.1

Thanks in advance...

Do you see "Unknown OpenCL driver version! Hashrate and stale shares may suffer" in the beginning of your log? If that's the case, perform clean reinstall of your driver.

I am with a driver version: 19.4.3 and Phoenix Miner 5.0e Windows/msvc - Release build. When the miner makes a DAG for epoch #340 is ok. But the 4GB card stops when the miner starts to make a DAG for epoch #351.

Hi Phoenix! You added nvidia Cuda 11 lib?

Thanks. Now there are no problems when switching ETH > ETC > ETH, didn't check ETC > ETH. Linux, AMDGPU-Pro Driver 19.20, 20.10.

We added additional fixes and some workarounds for the ETH to ETC switching problem in the new version PhoenixMiner 5.0e, but with some Linux drivers, there is no full stability (e.g. 19.20 are crashing if the miner starts mining ETC then switches to ETH but not if it goes ETH, then ETC, then ETH, and so on). But even with 19.20, switching should work fine until about 5-7 DAG epochs before the RAM of 4 GB cards would not be enough for mining ETC.

You can download PhoenixMiner 5.0e from here:

(MEGA links are no longer active)

If you want to check the integrity of the downloaded file, please use the following hashes (you need the last file PhoenixMiner_NVRTC_Windows.zip only if you want to mine BCI with Nvdia cards under Windows):

Let us know if this fixes the problems.

OpenCL 19.20 AMD Driver
OS: HiveOS 0.6-144
linux Ядpo 5.0.21-hiveos
4Gb AMD Asus Cards STRIX
Phoenix 5.0d

same problem ETH to ETC mining rejects

crash trouble on dofferent os and driver
windows 10 x64 os 1607 1703 1709
driver 18.3.4 18.6.1 18.12.1.1

We found an additional problem when switching from ETH to ETC but it seems it depends on the OS and driver version (and affects mostly Linux and only 4 GB AMD cards). We'll be ready with a fix or workaround tomorrow.
