gtx 1070 average utility is about 85

[shyandsy]

why gtx 1070 average utility is about 85% ?

the command line i used shows below
ethminer --farm-recheck 200 -G -F http://127.0.0.1:8080/rig1 --cuda-parallel-hash 8

You should try:
ethminer --farm-recheck 2000 -U -F http://127.0.0.1:8080/rig1

-G option is for AMD, -U is for Nvidia, leave cuda-parallel-hash at default.

GTX 1070 here too, I can not confirm this. My GPU has a utilization between 99% and 100% all the time.

[jimmykl]

My 1070s are ~98-100% too. @shyandsy could you try with the default --cuda-parallel-hash 4 and see if it increases utilisation?

[derubm]

also try :
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

@jimmykl @simonkern @derubm
I used the following configuration as start script now, the utilization has increase to 88% average.

But still not 98% average. are there any other suggestion?

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

ethminer --farm-recheck 2000 -U -F http://127.0.0.1:8080/rig1 --cuda-parallel-hash 4

@shyandsy make sure your cards are running in P0 state (looks like yours are running at P2)

first time to know there is state px for gpu How to do that on win10？ 发自我的 iPhone

To my knowledge Not possible with 10x series, will Check when iam at home

You can use Nvidia Profile Inspector from @Orbmu2k to turn OFF CUDA - force P2 state setting in section 5 - Common. Its turned ON by default as shown in this image. Be ware that other versions than 2.1.3.9 of this utility doesn't have this setting available!

There is also very handy GUI utility Nvidia Inspector from the same author which also accepts command line arguments. I am using it to overclock and monitor my cards. You can also check the P state of cards. You want to run your cards at P0 state.
To overclock my cards I am using this command:
nvidiaInspector.exe -setPowerTarget:0,XX -setBaseClockOffset:0,0,"-200" -setMemoryClockOffset:0,0,100 -setTempTarget:0,0,75 -setFanSpeed:0,100

• setPowerTarget:0,XX - replace XX with your values, lowers total GPU power usage (depends on card and can affect miner performance, you need to experiment to find settings for your cards, i am running my cards at 125W limit)
• setBaseClockOffset:0,0,"-200" - downclock GPU core (affects heat production, lower is better)
• setMemoryClockOffset:0,0,100 - overclock memory by +100MHz (most important for miner performance, gtx1070 can go up to +1000MHz but its rare and depends on manufacturing quality, you will probably be fine around 400-600MHz)
• setTempTarget:0,0,75 - lower temperature target (affects voltages and heat production. on some cards can also affect miner perfomance)
• setFanSpeed:0,100 - set fan speed to 100% (to keep everything cool)

This single line command affects first card only (with index 0) to see all command line arguments run:
nvidiaInspector.exe /?

Note: nvidiaInspector.exe has arguments to set/force P states of the card, but if you dont
turn off "CUDA - force P2 state" it wont work. This is also the main problem when you run on linux, I didnt yet find way how to turn off this setting which by default downlocks memory by 200MHz when running cuda apps

To run monitors only run:
nvidiaInspector.exe -showMonitoring

i switched to ubuntu 16. all works good now six gtx 1070 gpu，100% 发自我的 iPhone

I know nvidia-inspector is windows only but @shyandsy how did you configure your cards in ubuntu to get 100%?

I have used the coolbits flags on the X11 config to get the extra overclocking and thermal/fan controls and configure them by a bash script. Is there something else we can do there to disable the P2?

I can see on the UI it hits the P2 state immediately when ethminer starts up.

Try
NVidiaProfileInspectorDmW

For the best mining hashrate choose from sector "5 - Common":

• CUDA - Force P2 State (Set to "Off")
• Power managment mode (Set to "Prefer maximum performance")
