Hi, As the title suggest, can you clarify to me if I can run a ddr3 2133 on Gigabyte H81M-DS2 which according to the website (Gigabyte) that it supports only up to 1600 of DDR3. I have a 4GBx2 of DDR3 2133 G-Skill, others say I can use XMP to use the advertise speed of the ram which 2133Mhz. Currently my ram is running at 1600 which the defualt speed. Will it break my system? Thanks.
