MSI GeForce GTX 1060 3GB graphic card does not trigger its boost state when its GPU is loaded at 99-100% with NiceHash miner. Compare the values in the green rectangles:
GPU сore сlock is only 1544 while the boost value is 1759 and it stays the same even if I change master core clock with MSI Afterburner. And what is even more strange, the memory clock is only 1901.2 while its default value is 2002. When I start an application with relatively complex graphic interface, GPU core clock rises to its correct boost value, but memory clock remains the same:
The temperature is 52-69°C and fan speed is 47-62%, so there are no obstacles for boosting.
I have an impression that my graphic card does not boost while doing compute work (but partially boosts while rendering graphics) as described here:
- Gtx 1060 isn’t boosting while folding
- How to Squeeze Some Extra Performance Mining Ethereum on Nvidia
Taking into account that overclocked GPU works at 2100 the miner looses about 26% of his bitcoins, the formula is 1 – 1544 / 2100 = 0.26.
nvidia-smi -q -d PERFORMANCE nvidia-smi -q -d SUPPORTED_CLOCKS
and got the following result:
so I am unable to do something like:
nvidia-smi -ac 3505,1455
because I do not know the maximum supported GPU Clock.
I have Window 10 with NVIDIA driver version 388.13 (22.214.171.12413 with date 10/27/2017).
A quick Google search gives the following links:
- nvidia-smi not fully supported on GTX 1060
I can put GTX 970’s into P0 state by first quering SUPPORTED_CLOCKS and then issuing the nvidia-smi -i [x] -ac 3505,1455. However, for the GTX 1060 I cannot either query supported clocks nor set them.
I have 2 cards (ASUS ROG-STRIX-GTX1080-O8G-11GBPS and ASUS ROG-STRIX-GTX1080TI-O11G-GAMING). As soon as I start any CUDA app and card enters compute mode it lowers memory clocks from 11GHz to 9GHz for 1080 and from 11GHz to 10GHz for 1080Ti.
- nvidia-smi reports setting application clock not supported for GTX 1070
- No supported clocks ( Asus GTX 1080 card)
While doing the Google search I found very interesting article comparing NVIDIA and AMD cards efficiency telling that GTX 1060 is one of the best cards for mining.
Finally I switched P2 state off with NVIDIA Profile Inspector that I built from sources:
Now the card switches to P0 when the mining software is started:
Compare memory clock with pictures above:
on these pictures the card is a bit overclocked: GPU +152MHz, Memory +102MHz.
With GPU +197MHz and Memory +244 MHz I have about 300 sol/sec with Zcash on fly pool (I am not sure what is ‘sol’, but I guess that it is probably ‘solution’):
