#latency

Hello. As you can see on the screen below my ram timings are 16-17-17-35 although I set the XMP profile in BIOS with the 15-17-17-35 timings. I also noticed that if I change CAS latency in BIOS to 15, it jumps to 16, if I set 17, jumps to 18 etc. but if I set 16 or 18, the value doesn't change...
