GPU Miner : non official https://github.com/zumy/multiminer


How the test goes? I was courious to try it on a laptop with AMD Radeon HD 7550M/7650M, is not at all a powerfull card but it seems to support OpenCL as GPU Caps Viewer say
Code:
OpenCL 1.1, Turks compute units:6@500MHz

How can i run multiminer on win7 with this gpu and a Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz ?

Tried the precompiled binaries for win but always throw error: cannot find entry point clReleaseDevice in the dynamically linked library OpenCL.dll

I guess the Catalyst driver i have are too old or this miner needs OpenCL 2.1 at least...


Further try to gpu mine on a old unused laptop  to see how many hashes I can squeeze out.
Installed a newer driver and the multiminer now works, but from the pool i receive always rejected invalid share messages. I guess the problem is the settings are not correct?

You will have to play with threads and batchsize numbers to get best hashrate. Please note that batchsize is required to get a normal speed. It should be given in powers of 2 (though that is not mandatory, but is better). The batchsize represents the number of hashes calculated by the card in a call. Threads multiplied by batchsize multiplied by argon2d memory requirements (250KB for Zumy, 500KB for Dynamic and 4096KB for Argentum/Unitus) should not exceed available card memory

My card memory is 1GB (1024MB) so:  N° of threads (4) x 250KB x batchsize should not exceed 1024MB.

Anyway I tried all possible gpu-batchsize possible values but shares are always rejected.

Anyone gpu mining on a pool?


May I ask which pool you're using?

Tried icemining.ca and honorpool.org  both rejecting shares.
