The second is 8.8 correct.

800 if you have an s9i 14th/ and possibly s9 version as well.

You got to do some trial an error as I don't have all my machines to play with since they are being hosted so I am having the community help me figure out the best preset for the S9's

I would start at 700Mhz and work your way up. Most people have 725Mh/z work on all S9 models so that might be a good starting point too.
