H61 supports Ivy bridge.. its printed on the box in big yellow letters (I own the same mobo)..
what you need to do is update your BIOS..
It will not detect Ivy bridge CPUs natively,
upgrade to the latest bios using USB Flash tool and it should work right up..

Download according to your OS architecture
The download page states
1.Improve system stability.
2.Support new CPUs. Please refer to our website at: *support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us
So, I believe the problem should be fixed
