Sure you can. I'm not exactly sure about the settings in your X58's bios and how to overclock an i7 since I have a C2D, but I'm pretty sure there should be an option in there that should unlink your CPU from your RAM...in my case, it unlinks their FSB (i7 doesn't have a Front Side Bus). Once you've done that, then just crank your ram up to default speed and set it to 1.65 in voltage settings.
