I tried putting a Samsung DDR3-1600 4GB512Mx64 CL11 Memory and spectek 4gb ddr3-1333 cl9 udimm into a H81M-K mobo and it wont boot up i can get in the bios it recognizes the ram its set to the lower speed but it wont boot up and keeps on restarting any suggestions? I tried putting them in different slots but it won't work. I know mixing different rams is bad but i already bought them btw i have an older ram kit 2x2 1600MHz it works fine.
