use ccminer like
ccminer.exe -a quark -o stratum+tcp://esppool.sytes.net:3334 -u test -p pass
is there an espers ccminer I don't know about? :-)
Lol does ccminer not have quark algo? :p If not I am completely sorry for pointing in a direction that does not work. Could of sworn it was added to ccminer :/
but regardless sgminer is for amd cards :p

Yes ccminer does have the quark algorithm.
But ESP uses hmq1725 algo instead.
My sgminer should work on 750 as well, it is plain opencl which is supported by nvidia. But I never tested it.
I 'm mining by sgminer[pallas].
