yeah it is an older model, nvidia770 but I've got it to mine skunk before. now its having a hard time mining the x17 algo which I've seen my card run as well...and now skein; although I've never tested that with other mining programs. but yeah all of the same errors. unsupported
this is the bat I used for mine skunk only on zpool and it worked.
ccminer-x64 --algo=skunk -o stratum+tcp://skunk.mine.zpool.ca:8433 -u 19L7Y7yf1kUW25JMrVSRWnJu9ZZhp5HGUq
now this is the line this miner uses and says my device isn't supported.
Bin\NVIDIA-skunk\ccminerskunk.exe - skunk -o stratum+tcp://skunk.mine.zpool.ca:8433 -u 19L7Y7yf1kUW25JMrVSRWnJu9ZZhp5HGUq
try ccminer 1.7.6, or 1.8-dev for algos other than skunk which is only going to be in the newest miner apps since its a new algo; If i stil had a 7 series, I would test all the copies I have collected over the years... But for other algos, like X17, skein, etc... try wither of those 2 versions.
should be able to find links to them on github or cryptominingblog.
