I recently built a new PC with a DP55KG motherboard, an i7 860 and 8gb of Corsair CMX4GX3M2A1600C9. In the BIOS when I choose the XMP profile for the RAM, it sets the speed at 1600Mhz with a voltage of 1.65 volts. It seems to be running fine, but is this voltage safe to use with this motherboard ??
Gotcha. Last question... do you think that I'm shortening the lifespan of my processor by running the RAM at the XMP profile, or should I let it default to the 1333 at 1.5v ??? I've never overclocked anything before, I just figured the XMP profile would meet Intel's OK.
you are not overclocking, you just get more performance out of your memory safely by using the xmp-profile. it's up to you to use it or leave it at SPD settings (default). your money, your risk, your choice
