So I'm using an i5 4460 on a Gigabyte GA Z97P D3 with GSkill RipjawX 2133 memory.. I can use 2 out of 4x4GB sticks in slots marked 2&4 perfectly at 1600 or 2133 but 1&3 don't work in any combination. If I use ram in either of those slots then it continuously resets after 10 seconds or so and I can't even enter the bios. I don't really have any idea about memory timings or overclocking so I don't know if it's a motherboard issue, something to do with the ram or my bios settings? The mobo and cpu can supposedly support 2133 memory so I'm not sure what's happening. Any more info then please ask
