Need help about using cuda configuration parameters for gtx 1070

[alptolga]

I need help for configuring cuda configuration parameters of gtx 1070
What is the best parameters? I need advice.
CUDA configuration:
--cuda-block-size Set the CUDA block work size. Default is 128
--cuda-grid-size Set the CUDA grid size. Default is 8192
--cuda-streams Set the number of CUDA streams. Default is 2

The best way to figure this out is to run your own benchmark.

I'm using the same cards and so far I've found the defaults are quite good

[alptolga]

Benchmark just show the cuda grid size. There is still no info about stream and block size.

The best are the defaults.
I try almost all combinations.

My script:

ethminer.exe -RH -U -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O wallet.rig

For NVidia Power State 0 (p0) you can use NVidiaProfileInspectorDmW

For Win10 tweaks you can try Windows10MiningTweaksDmW.

I use msi afterburner to overclock my cards and use nvidia-smi for setting the power consumptions of the cards. I do these processes after miner starts to mine so I don't live any problem when generating and loading dag to the cards. After overclocking the cards there is no way to set the cards to p0 state. Anyway with overclocking procedure you use the cards in its uppest limit. P0 is useful just for when you use it in stock frequency.

What overclocking settings you use? (-50/+500 & 65% TDP -- Temp=52C)

[alptolga]

+800 memory and 10 watt over the minimum tdp of the cards.

I think this issue can be closed.

This is not an issue as written on the topic title. This is mostly collecting user experiences and advices for mining with cuda gpus. Even so if you feel your self uncomfortable as long as it remains open. it is easy to close the topic.

Sorry about false cleanup!
I use MSI Afterburner (-50/+500 & 65% TDP -- Temp=52C) not NVidia-smi.
ethminer.exe -RH -U -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O wallet.rig
I believe the default values of miner are the best for GTX1070.
