It's worth noting, especially if you use older DDR3 memory, that you need to keep the VCCIO/VCCSA and memory voltage within 0.5V of each other. This follows on from the same rule set by Nehalem and Lynnfield, but given that the whole Sandy Bridge die is now 32nm and operates at a lower ~1.15V voltage, mixing this with older 1.65V+ DIMMs puts it on the fringes of acceptable long-term reliability.
