1.65v RAM running at 1.5v safe on ivy?

So, my son and I built our first computer last month and thanks to excellent advice on these forums it went smoother than I could have hoped and has performed flawlessly from the first boot, but as I continue to follow the forums this question has arisen.

When I researched the RAM and found it was compatible with my MOBO and (I thought) CPU, I was unaware of the different voltage requirements between Sandy and Ivy bridge and the RAM I purchased is 1.65v. Here are the pertinent parts of the system:

I5 3570K CPU

Kingston Hyper X Blu 8GB (2x4) (newegg item #N82E16820104262) http://www.newegg.com/Product/Product.aspx?Item=N82E168...

GIGABYTE GA-Z77X-D3H MOBO

After the initial panic, I booted BIOS and checked the voltages to find that the MOBO has the RAM throttled to 1.5V and 1333 already by default.

So my question is: Will this be perfectly safe as long as I don't manually change the voltage to 1.65? I don't want to change anything if I don't need to, but would rather not shorten the lifespan of the highly acceptable CPU either....

Consider yourself lucky, you got 1.65v ram that's operating correctly at 1.5v.

Most DDR3-1600+ ram that requires 1.65 volts will also operate at DDR3-1333 or lower at 1.5 volts

The 1.65V on most 1.65V DIMMs is only required for XMP profiles with extreme clock and/or timings. Most of these DIMMs also have 1.5V SPD profiles with standard clocks and looser timings.

So it looks like it was just unnecessary panic over the whole 1.65v hubaloo then, thanks!
