Hey guys just got 2 new sticks of ddr3 8gb corsair vengeance. Tried setting the clocks to recommended 11-13-13-31 with 1.652v with linked settings They are sat in slots 2 &4 on my motherboard because I can't access slot 1 because on my CPU heat sink. Would they be better in slots 3&4? Also my motherboard settings would only let me set them as 2133mhz max instead of the 2400 they are rated at. Mother board is a main gd-65. When I boot with these setting I get a black screen. What have I done wrong?
