Has anyone heard if the bios can be mod, or overclocked through ethos or window? If so, it may hit 30 mh/s

I am mining both btc and eth but soon to be mining dash and ltc. I would like a easy to use (low fees) multi coin pool and wallet for those 4 coins. any recommendations?

I would like to get my S9s, ethereum, and soon to be antminer L3,s hosted. The ones I see ads for seem to have some bad reviews. Can anyone recommend a good hosting company.
