Can you run three dual channel kits on an x58?

Can you YES should you MAYBE NOT. Placing 3 kits of F3-12800CL8D-8GBXM is NOT guaranteed to work, the only guarantee is a Hexa-kit. More than likely the F3-12800CL8D-8GBXM will NOT run 1600 MHz 8-8-8-24 but 'probably' run 1600 MHz 9-9-9-24 @ DRAM Voltage of 1.50+~1.60v with a QPI/DRAM Volatile of 1.20~1.25v. XMP will not work so you'll need to set everything manually.
