I have a 2133Mhz 2x8GB RAM. I normally use the XMP profile 1 in BIOS but now I wanted to try to overclock it to 2400Mhz. So.. in BIOS, I simply changed the DRAM frequency to 2400 and saved. I left everything else as it was before but now, with this single change, the BIOS only reads one memory stick (8GB). If I revert the change and use the auto DRAM frequency, it reads both. Why? Thanks for help.
