Hi Guys. I'm currently mining ETH with my existing GPU. Details below.

OS: Windows 7
GPU: MSI GeForce GTX 970 4G gaming
Speed: ~17.5 Mh/s
Nvidia Driver: 384.94
GPU Clock: 1501
Mem Clock: 3505
Snapshot:
ETH - Total Speed: 17.529 Mh/s, Total Shares: 136, Rejected: 0, Time: 09:51
ETH: GPU0 17.529 Mh/s
GPU0 t=61C fan=81%

-- I've seen some people claiming that they were able to run GTX 970 up to 22Mh/s. Can someone advise on how to do this?

-- There are also some forums stating that you can set the GPU to "Optimize for computing" which help increase the Mh/s of their mining. However I can't find this option in my Nvidia control panel. Need help on this.

-- For this purpose, is it better to buy 2 GTX 1050 Ti (rated 75W vs 140W on GTX 970) and do an SLI configuration?

-- Anybody here with the same set up as mine, come share your Mh/s speed and how did you achieve it.

PS: I haven't read through the whole thread since there are so many pages already. Please be kind enough to refer me on that page in case these questions has been answered already. And given the fact that i'm mining while writing this makes my browsing capability slow.

Thanks ya'll. Happy mining.

Thanks bro. My GPU is already running on OC hence GPU clock at 1501. I'm planning to buy 2 1050ti but as you mentioned I think its better to run on 2 1050ti with almost the same power consumption as 1 GTX 970.

But i'm still keen on running my GTX 970 @ 22Mh/s because it will be the same as 2 1050ti in terms of hash rate and power consumption. The only difference is I won't spend money to buy 2 1050 ti.

Hope someone here can help me at least for the "Optimize to compute" option.
