Apparently mining but no valid shares yet

Post by Sabbuth » Mon Jun 11, 2018 2:09 am

Hi,

I'm not sure I'm mining and how it is supposed to look like.

When I start a mining job the output looks like this:
[2018-06-11 07:52:40] Starting on stratum+tcp://prohashing.com:3333
[2018-06-11 07:52:40] NVML GPU monitoring enabled.
[2018-06-11 07:52:40] NVAPI GPU monitoring enabled.
[2018-06-11 07:52:40] 1 miner thread started, using 'scrypt' algorithm.
[2018-06-11 07:52:41] Stratum difficulty set to 65536 (1.00000)
[2018-06-11 07:52:41] scrypt block 1437448, diff 10965232.725
[2018-06-11 07:52:41] GPU #0: 32 hashes / 4.0 MB per warp.
[2018-06-11 07:52:42] GPU #0: Performing auto-tuning, please wait 2 minutes...
[2018-06-11 07:52:42] GPU #0: maximum total warps (BxW): 1492
[2018-06-11 07:53:00] scrypt block 6762232, diff 87868.037
[2018-06-11 07:53:58] scrypt block 1437449, diff 10965232.725
[2018-06-11 07:54:26] scrypt block 6762233, diff 84488.763
...

The batch file for the ccminer application looks like this:
ccminer --algo=scrypt --url=stratum+tcp://prohashing.com:3333 --user=Sabbuth --pass="n=GTX1070Usr,a=scrypt"

When I open my task manager I see the performance of the GPU swinging at high levels. Nevertheless I never get any share from the mining work.

On the prohashing website -> earnings tab

Difficulty: 65,536
Target difficulty: 65,536 (dynamic)
Work restart delay: Need more shares
Current restart penalty: 1.000
Minimum network difficulty: Not set
2hr share estimate: 0
2hr avg Hashrate: Need more shares
Since first share: No shares yet
Mode: Pay-per-share
Merge mining restarts: dynamic

I don't have any statistics whatsoever because apparently "no recent mining has occurred" according to the average mining efficiency block on the earnings tab. At the same time it always looks as if there was an attempt to mine coins but it seems the jobs are never completed.

Any ideas of what the problem might be?

Hope you can help me thank you.

Greetings,
Sabbuth

Mining scrypt algorithm on gpu could take a long time between shares at 65536 starting difficulty, you could set d=16384 for minimum static difficulty if you really want to mine scrypt and see shares more often.
It's probably going to cost more in power to run the cards than you would make mining scrypt. Equihash is a better choice for GPU mining on prohashing. You might want to try a different miner program for equihash, ccminer could work but there are faster programs like ewbf or dstm.

Thank you Spauk, I'm gonna try with another algorithm and see how it works!
