DRAM settings on ASUS P6T Deluxe V2

OK here is the question if I set the Multiplier to 20*200 and Dram Frequency to 1603 I cannot get it to work I have the Dram voltage at 1.65
CPU Voltage at 1.250 QPI at 1.250 The setting work fine for 1203 MHZ My Memory is super talent 12800 DDR 3 part number W1600UB2G7
I am currently running at 3.8 and Memory at 1523 MHz timings 8 8 8 24

Now I can get it run at 1603 or higher if I set DRAM Voltage to AUTO
I was told not to run the the DRAM Voltage at AUTO on another board by one person, as it could damage my CPU
I would like further confirmation on this
Any and all help is always appreciated by this old retired Master Sgt USAF

That is not true as long as you have your Dram Voltage within .5 of of the CPU/QPI Voltage. I have my CPU and QPI at 1.26250 and my Dram at 1.7 which is within the .5 range as 1.26250 plus .5 equals 1.76250. This can be proven on a ASUS P6T Deluxe Board and Look at the setting for XMP Xtreme Memory Profile, it will show a DRAM of 1.9 if you boot into windows you will see the voltage is 1.4 plus on CPU Z You will see the same thing in DOCP Dram Over Clock Profile
