Error -61

[ftsguy]

I'm getting this on my rx 550's.
clCreateBuffer failed (c:\users\user\documents\github\randomx_opencl\randomx_opencl\miner.cpp, line 112): error -61

It's because dataset alone is more than 2 GB. You have to allocate dataset on host:

--dataset_host

in command line.

[ftsguy]

yeah i get "Couldn't allocate dataset using large pages." I tried intensity at 768 and 256 and workers at 2 as well. It locks up the pc pretty bad when i tried it.

[SChernykh]

Try intensity 384, workers at 8 and bfactor at 8. RX 550 has been tested before and did 17 h/s. RX 550 should be able to do over 100 h/s with optimized code (when it's done).

@ftsguy Can you try https://github.com/SChernykh/RandomX_OpenCL/releases/tag/1.0.4-7 ?
This command line should work for you, I expect 100-120 h/s for RX 550:

RandomX_OpenCL.exe --mine --validate --dataset_host --intensity 512
