I think I jumped the gun buying a new mb/cpu/ram and picked up 4 gigs of Patriot Sector 5 memory but I'm reading the new sandy bridge's need 1.5v ram? The memory I picked up is 1.65

Can I still use this and maybe try to undervolt it? Or should I just send it back and get the correct voltage memory? Just don't want to fry my new setup
Thanks
