No luck with an initial attempt on a 750ti + CUDA 7.0.
Can anyone confirm that this can work on 750ti?
MINING ETHEREUM ON A 750TI IS POINTLESS--
The way a 750ti adresses memory makes it a poor choice for mining Ethereum (ETH). Eighteen months ago, when the mining for ETH was just started, it was possible to get about 8MH/s per 750ti. The DAG file grew too large for a 750ti about a year ago. Reported hash rates for a 750ti are from 1-4 MH/s today; this is only 40-50% efficiency at best.
A 750ti is better purposed mining other coins. Claymore might possibly mine on a 750ti, but not well. The time spent experimenting is less time spent mining something like Library Credits (LBC) at 50MH/s per card. --scryptr
