For all you Nvidia guys:

I have an 'old'  GTX 465 on my daughters PC (XP) and got it to work (110kh) with the following:

Latest cudaminer with Scrypt-Jane support (2014-02-02)

and the following config / .bat


//================================================================
setx GPU_MAX_ALLOC_PERCENT 100

cudaminer.exe -C 1 -i 1 -H 2 -l auto -o stratum+tcp://xxxxxx3 -u xxxxxx -p xxxx -a scrypt-jane:UltraCoin
//================================================================

can also be done by specifying starttime,min,max instead of coin name eg -a=scrypt-jane:1388361600,4,30

working away on leetpool with no problem
