I just finished a new build and the system seems to be underperforming quite a bit. I installed a Gigabyte B250m - DS3H Mobo, i5-7500 Kaby Lake, Aegis 2x4GB DDR4 RAM @2400, and a GTX 1060 3GB. I've done some benchmarking and the memory seems to be the most consistent issue. I've checked the slotting on the RAM and everything seems ok, but still have issues.
