What clocks would you recommend for 750 ti and a 980? I thought I remember someone here saying that memory clocks didn't make that much of a difference. Thanks.
You need to find out yourself. But I can give you a hint. The lyra2v2 can do 5.2MHASH@750ti with the sp-mod opensource kernal. But it won't do it with a gpu core of 1500MHASH, and intensity to the max. To mine with a profit you need to know your cards well. Changing the sourcecode in the kernals is not enough.
The opensource kernals kan perform 15-20% bether with a right config and overclocks.
