0.13.0rc7 - Stale solution block the miner and lose connection

[Rodriguevb]

Hello,

i have this error sometime on Xubuntu 17 and the last stable version of ethminer 0.12.0.
Too much overclocking or my parameters are wrong ? ( cuda-parallel-hash 8 cuda-streams 10 cuda-grid-size 8192 cuda-block-size 512 )

And i have so much Submitting Stale Solution too..

try using latest 0.13rc7, but usually this means a lot of overclocking. Try going to stock clocks and then increasing to see when you start seeing these errors.

With 0.13.0rc7, the stale solution block the system

btw this error is strange : Parse response faild: * Line 1, column 29 Missing ':' after object member name

Check your GPU temps and limits. I have 1 GTX 1070 that would become very unstable above 61C. Assuming you are air-cooling, set your max temps to something around 60C so that the thermal limits will kick-in and slow your card down if it starts to get too hot.

@Rodriguevb
just checked your settings "cuda-parallel-hash 8 cuda-streams 10 cuda-grid-size 8192 cuda-block-size 512"
so for me (4 GTX 1070 and 1 GTX 1060) default settings of ethminer outputs much better hashrate (more stable)
so defaults are cuda-parallel-hash 4 cuda-grid-size 8192 cuda-block-size 128

My GPUs works at 50C +-, so it's 'cold' :)

And defaults parameters cuda-parallel-hash 4 give a bad hashrate for me ( 28 (4) / 31 (8) ).

What is the main difference between cuda-parallel-hash and cuda-streams?

@Rodriguevb Shouldn't happen with the final release 13. Please retest.

I think this issue can be closed.
