Memory auto xmp profile 2400mhz DDR3 DRAM voltage 1.515 instead of rated 1.65v?

Whys auto dram voltage showing 1.515 instead of 1.65v
Should I manually set it to 1.65v

Or is it likely fine as-is if my pc seems to be running fine so far?

Should I run a memory test or something?

G.SKILL Ripjaws X Series 16GB (x2 I have 32GB ram total installed)

1.5v is default voltage for ddr3
1.65v is for overclocking (for either increased frequency or lowered latencies)

OK I set it to 1.65v manually and did 1 hour pcbdestroyer config with testmem5 and its a success!!!!
No instabilities. No errors bsod or freezing.

I also had to raise up my CPU overclock by 10mv
From 1.395v to 1.405v!!
To make 4.6ghz stable. with my 3770k..
My temperature reaches about 80-82*C peak on hottest cores.
