XMP profile 1 defaulted to DRAM 1.9v?

Hello everyone,

New member, just completed 1st computer build. Never o.c'd but would like to learn. My first step after much reading and research was to enable the XMP profile in my BIOS. Only 1 profile was available - selected it. Computer boots just fine. Open CPU-Z and Turbo V and it shows my DRAM voltage at 1.9v. Here are a few of the other settings:

7-7-8-24-2N-1.6v

BCLK 134
CPU Volt 1.22500
DRAM Bus Volt 1.9
QPI/DRAM Core Volt 1.375

All 12 gb of ram are running at 1603.09.

I emailed GSKILL support and they said the 1.9 could damage components - set it to 1.5v.

Why would the profile default to 1.9V? I thought the profile was read off the RAM sticks?

Thanks for your help!
Kevin
