I'm having an issue with the hash rate of my 970sc cards. They're both only getting 3.15Mh a piece, and I am about exhausted of ideas as to why. I have tried installing the 347.52 drivers, and when I install the cuda 8.0 (while doing a custom install to de-select drivers that over-ride the 347.52 ones), the miner will not run for me (says that no gpu's are found). With the latest updated nvidia drivers I get the slow speed. I am running win10...has anyone has similar issues with a 970?
Also, I tried using the v7.3 miner and get the same hash rate as with the v9.5 one.
I'm running a GTX 970 and in dual mode I'm getting about 3.2 Mh/s on ETH and 54 Mh/s on SC.
I've tried changing the nVidia driver to the newest as well as the recommended 368.81, hash rates stay the same.
I've disabled all the power options I've found on the nvidia panel. My GTX is running at around 1417mhz. GPU temps never get much above 70C, and tweaking the GPU CLOCK OFFSET/MEM CLOCK OFFSET change the hash rates slightly but eventually lead to the box halting. I tried copying the CUDA dll form one of the child directories on the Claymore 9.5 zip, the execution reported that CUDA 8/7.5 were available. This also didn't change the hash rate at all.
I've tried editing my start.bat to include the following settings:
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 1
Nothing seems to have made a difference. I honestly feel like some video games tax the GPU more than this... the GPU fans spin up more in some games.
