v2024.3.3b5 (Windows): No hashrates for SHA512256D on AMD RX580 #12
Comments
As always a complicated bug as it seems. I guess it is a problem with the kernel - maybe a command is not supported- need to make a 'debug' version to find the details. |
can you please check if you see a file in the folder GpuConfig? Should be something like CompileError4.log |
Folder 'GpuConfig' exists. But no files in that folder. |
Hi, can you please replace the opencl driver of TT from DeviceTypes folder with the one attached? |
I replaced the file - still no hashrate. Ans also no file in the 'GpuConfig' folder |
Hi - thanks for the update. Need to add more debug output to fix this. |
Can you please try this one again - added more output. |

OK - looks like we getting closer. Please replace now the algo with the attached one. Will again produce more output. |

OK - seems like 'Create OpenCl-Kernel' does not return....let me check |
ok - now please replace the main exe. |

Date / time in printout is obviously wrong. Timestamp of exe is Donnerstag, 25. Juli 2024, 10:47:55 |
The exe you started is correct: 12:20:53.634 Version: TT-Miner - Beta 5 (2024.3.3 Jul 26 2024) opencl kernel compiler does not return. Need to find out why. |
may I ask you to test again with this new opencl module? |

It contains more information. So, I hope this is the last try, main & opencl: |

Can you try again? I switch off most of the opencl compile options. |
I cannot download the file... ??? |
No idea what went wrong.... |

Hi - can you please give this another try? |

Hi, can you please try to mine NOVO (algo sha256dt). The algo uses a similar structure. I would be surprised if that works. |
Ok. Thanks. Must be something in the algo itself .Am 27.07.2024 13:12 schrieb Useless Guru ***@***.***>:
NOVO and all other algos except [SHA512256D on AMD RX5800] work just fine:

Hi, I modified the algo to find out which part of it the opencl compiler doesn't like. Please note that you might see extrem hashrates but no shares. This is just a test to find out what the problem is. Please replace the existing algo from the Algos folder: |

Broken - does no longer compile. :-( |
ok - lets find the point.... |
green - it compiles! |
green - it compiles! |
strange... |
green - it compiles! |
coming close to the last failure now |
That compiled - took 24 seconds. |
how long did it take before the last modification? |
12:56:38.600 Krnl[04-RXD]: *OpenCl-Kernel configuration ready (OL_G-A080#0-20). (9.6 secs) |
oh - maybe that is the problem. It does not hang - it just takes very long to compile.... maybe I need to spilt the algo-function into smaller parts |
my igpu and cpu does not take very long to compile: 13:10:12.072 Krnl[03-RXD]: *OpenCl-Kernel configuration ready (OL_C-A080#0-30). (2.6 secs) |
Nope:
|
13:21:42.700 Krnl[04-RXD]: *Create OpenCl-Kernel configuration (OL_G-A080#0-20) |
maybe it takes very long to compile? |
13:26:20.285 Krnl[04-RXD]: *OpenCl-Kernel configuration ready (OL_G-A080#0-20). (60.4 secs) |
Could you modify TTminer so it does not report 0 hashrate until mining is really ready? |
yes, but lets first fix this problem |
i guess it just takes very long to compile - and no other problem...... |
Original algo - should find valid shares (if kernel is compiled and ready) |
13:31:21.040 Krnl[04-RXD]: *Create OpenCl-Kernel configuration (OL_G-A080#0-20) Will try original again. |
do you run the system from thumb drive? any limitation for temp files? The opencl needs some space to get the kernel ready - but most likely the same space for most of the gpus. |
No. Standard Win11. All other algos compile just fine. Also my RX5700 runs all TT algos like a charm. |
is it possible that the 580 uses an old driver? |
Same as RX5700: 20.04.2023 / 31.0.14051.5006 / 3516.0 That is not so old. Other miners work fine with that version. |
Any news? |
Hi- I run out of plausible ideas. Guess I need to buy a 580 and debug here in more detail. Let me clean up the code and fix some other bugs and contiue. |
No matter how long I let it run I get no hashrate with RX580.
AMD RX5700 with same command line instantly finds shares. Also RX580 works fine with other algos.
