Just bought 1.65v ram. Am I safe using it with 3570k?

I think I would err on the safe side and return it.
1.65v is apparently the highest voltage allowed, but I would not feel comfortable running there.

You could check the kingston ram configurator to see if it is supported on your motherboard.
I am guessing that it is not. If it is not supported, you will get no help from either the motherboard maker or kingston.

I'm assuming its going to run at 1.5v at 1333mhz. 1.65v is used to run it at 1600mhz. Will there be that much of a performance boost between 1333mhz and 1600mhz? If there isn't there's really no point in going through the hassle to return it i guess.
