Question on Voltages for OCZ DDR 3 1600 Mhz ram

Need to post your motherboard brand/model and the model of your memory to get any help on this.

A program like SiSoftware Sandra will give you both if you don't know it and tell you the current settings for the RAM voltage. CPUz will give you the same info and a chart with the voltage specs at different speeds.

All versions of Windows will lock up. Once you have your system running right, might want to try re-format/re-installing - always my best solution.

OK, here's the OCZ page on your memory:

Here's the Asus page on your board:

Be sure to save all the pages there to a folder and download everything, even if you don't need it and likely you won't.
=============

The manual states sec 2-12 pg 36 "According to Intel CPU spec, DIMMs w/voltage req. over 1.65V may damage the CPU ... recommend DIMMs with V below 1.65V."

But below that, they show only one 1.65 vendor and two at 1.9V.

Section 3-21 pg 89 on the BIOS says QPI/DRAM Core voltage (auto) ranges from 1.2V to 1.9V - but 1.9V is only supported if you set a jumper.

Here's what I recommend. I chose to return my RAM that required the max voltage my board would provide because it meant I could never get the most the memory was capable of. You're in the same situation, the min. requirement of your RAM is the max the board puts out. I'd RMA your memory and shop for something with a 1.65V base.
