I am building a core i5 system and have purchased all the components already. I have the Gigabyte GA-P55A-UD4P motherboard and the following memory:

CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I didn't realize that the motherboard recommends only 1.5 volt memory, and the memory I have is 1.65v . Is this going to cause a problem or damage the motherboard? Should I buy different memory before trying it? I don't really know much about memory or voltages, I see some of the available sticks have voltages up to 1.9 so i figured 1.65 was pretty reasonable.

I would return or exchange it for lower voltage RAM. But, if you choose not to do so, then you may have to enter the BIOS (using only one stick of the RAM) to:
-- verify or adjust the RAM voltage to 1.5v,
-- adjust the RAM speed to 1333MHz.

Save and exit BIOS. Shut down the computer and disconnect the power cord from the surge supressor wor supply outlet.

Firmly seat the second stick of RAM.

Re-connect the power cord. Power-on the computer.

If you still can't boot to the OS, go back into the BIOS and increase the RAM latency timings from 8-8-8-24 to say, 9-9-9-30.

I'm using 8G of the same RAM on that motherboard. No problems. I believe it is running at 1333MHz though.
