I wonder how these people on the forum made it to 400MHash/s. Even with only one single card, my GPU simply freezes when I push it to 365MHash/s at 1.2V 925MHz core

You sure it's worth it? I get 350MH/s on stock voltage with only 850MHz core. What's the stock voltage on your GPU?
What temperatures are you seeing?

725MHz/1.088V

Income from increase in production rate is far greater than increase in cost of electricity, though the power consumption grows exponentially against voltage level and core speed. Temperature should be not a concern - @870MHz the temperature does not even exceed 55 C, with 90% fanspeed.

For now I changed them back to 1.088V/870MHz, waiting for my new 1200W PSU.

*More PSU are needed to compensate the increase in power consumption from GPU. In my calculation I did not put that into consideration. To find the optimal strategy I have to collect more data.
