Hello all. I want to buy 2 new ram sticks of 4GB each. My motherboard manual says that it supports 1333 MHz of speed and 1600 MHz of speed overclocked. I went into the BIOS to see how to overclock my mobo once I get the new sticks, since they are at 1600 MHz, but I didn't only see 1333MHz and 1600MHz as options. I also saw 1866 and more. So, can I buy 2 sticks of 8GB and with 1866 MHz of speed instead of 1600 and overclock my mobo so it can support that speed or will it be hurtful for the energy spending and health of my ram? Thanks in advance!
