I'm having issues getting this memory to run on my motherboard. I've tried clearing the cmos and it will come up with the post screen and I can access the bios but once I select boot with optimum settings it restarts and the screen doesn't come back on. I'm running with my old 4gb set in atm and it's fine. On the gigabyte website it says it supports 16gb. I set the timings to 9-9-9-24 1600mhz in the bios with voltage set to 'normal' (I think that's 1.65v). I know it's supposed to be 1.5v but i can't undervolt it. Any suggestions?
