VTT Voltage

[odun]

Question on vtt voltage.

I'm not trying to overclock or anything. My cpu supports 1600mhz ram. So I got some ram rated at 1600mhz.

Problem is I have to change the bios xmp to profile1 for the ram to be rated as 1600mhz. Some reason they're defaulted to 1300mhz.

Now when I do this the vtt voltage jumps from 1.05 to 1.30.

Is it same to run them at 1.30?

Ram used are Corsair Vengeance 8 GB ( 2 x 4 GB )

VTT controls the IMC (Integrated Memory Controller) voltage, and not the voltage to the DRAM modules. And without knowing anything about your system, we can't tell you if a VTT of 1.30V is safe or not. Also enabling the DDR3-1600 XMP Profile is unnecessary, as raising the DRAM Frequency to DDR3-1600 is normally all that's required, w/ a possible bump in the VTT voltage to compensate for the higher frequencies and / or larger quantity of RAM.
