I made some tests on 1050 Ti with cudaminer v1.0.0 using the --mode 2 option which gives the best results, also i have reduce TDP to 58W and the hash rate is about 450KH/s, i was expect from this card to do about 520KH/s on 55W, but ι failed to my calculations.
Changing SM_50 to SM_52 i think gives more stable hash rate.
