Equihash failing to Benchmark

[Ricardo1701]

I have a GTX 750 TI, and according to profitability calculator, Equihash is the most profitable algorithm, however, I can't get it to work on my computer, here are the relevant part of the log files:

On this next one, the first one is with the extra parameter "-c1 1", and the later is with no extra parameters:

Also, I found out that calling the excavator manually, using the following parameters excavator.exe -a equihash -s [equihash URL] -u [my bitcoin address] -ca it works, however, adding the another -ca at the end of the call makes it fail, and somehow, I think that is the issue at hand

[Squall-Leonhart]

the GTX 750ti has insufficient video memory to mine on with Nicehashminer's client settings.

You could turn down the intensity in the extra launch parameters as that is what worked for my GTX 960.

[Ricardo1701]

Even turning down intensity didn't work, I guess my video can only run one process at a time, and nicehash miner uses 2 process at the same time
