DRAM Voltage

Ive got an ASUS P7P55D-E PRO Motherboard and 6GB G-Skill (3x2GB) DDR3 1600MHz/PC3-12800 Ripjaw Memory Kit CL7(7-8-7-24) 1.65V

My system is running fine (Win 7 Pro 64bit), in Bios I set the memory to 1600Mhz, but my DRAM Timing is set to Auto ( shows it running at 1.790 ), should I leave it running as this or is it advisable to change it to 1.6500 ?

Are you sure you DRAM Timing is at 1.79 and not voltage? You need to set the DRAM Voltage to 1.65V, 1.8V can actually damage the IMC on your CPU.

You'll need to change your memory timings to these for optimal performance.

CAS - 7
tRCD - 8
tRC - 7
tRAS - 24
Command Rate - 2T

Lmao, Yea I meant DRAM Voltage :pt1cable:  sorry ;) 

Why is the Bios running Auto be running it at 1.790 if it damages the IMC ?

Asus is crazy? ;) 

No idea, Intel's max used to be 1.65V, they raised it to 1.7V I believe but best keep it as low as possible.

It's meant to be tRP sorry, and it's RAS PRE# in your BIOS. Just leave the command rate for now. Set the DRAM Voltage to 1.65V.
