Here is the Gigabyte support page for H61 motherboards: GIGABYTE - Motherboard - Socket 1155
I don't see your model listed. Are you sure you have the model number correct?
At any rate, I wouldn't update the BIOS unless I had a very good reason and knew that another BIOS would solve a particular problem I had.
If you meant GiGABYTE H61M-S2P-B3, it has 2 versions: 1.0 and 1.1, and we would need to know which of those you had.
