I have a set of 32GB (2x16GB) dual-sided Samsung b-die sticks I'm trying to overclock. Right now they're sitting at 3200 14-14-14-34 2T 1.36v. I was able to boot into windows at 3400 14-14-14-34 2T 1.37v, but memtest gave an error, so I'm wondering what should be the first thing I consider going forward? Increasing voltage, or loosening timings? I don't want to loosen timings too much, but I would like to up the speed a bit in preparation for Ryzen 3. Current CPU is an i7-8086k on a Maximus X Apex.
