Will my 1.65V RAMs damage my 3770K if i set my VTT voltage to 1.15V?

I have RAMs like this 2 kit 4x2 Gb.Now I know Intel do not recommend to use 1.65V RAMs with Ivy Bridge,but If I'm right,then they should be fine if there isn't more difference between my DRAM voltage and my VTT voltage than 0.5V.Am I correct?

Not really, because your RAM is the 2000mhz and the i7 3770K only supports up to 1600mhz, if you run the speed at 2000mhz then you need up the voltage to keep your computer stable. The 1.65V is for the standard 1600MHz RAM only.

My RAM has 2 XMP profiles:1866 and 2000,both at 1.65V.Jedec profile is 1333 at 1.5V.So if you mean i have to give my RAMs more voltage than 1.65V to be stable at 2000 MHz,than I know i don't,they were always running at 1.65V and 2000 Mhz,but just recently I updated my BIOS,and all my settings and profiles wer lost,and I'm not sure that increaseing the VTT to 1.15V is enough for my computer to be stable,but it was for the last year,a little more,i bought my CPU shortly after it was first released,and my RAMs around the summer of 2010.

You can go to the BIOS RAM section to set up RAM XMP profile, and let the software does the rest. Check the manual.

Yes,the XMP profile will set the right settings for the RAM,but not for my CPU,so one thing i'm sure at that i have to increase the voltage of the IMC,I'm just not sure that that is the only thing i have to do,and then iI'll be perfectly fine.
