So I have 2*8GB Dual Channel ddr4 2400mhz ram and when i check on CPU Z to be sure everything is right in shows in the DRAM section 931.1 MHZ. now i know you are supposed to multiply it by 2 but 1862 doesnt come close to 2400. I asked my friend which has 2*8gb 2400mhz ram too and he told me his DRAM is 1200.....what could be the problem ? Everywhere else on my pc and command prompt it is writted that i have 2400mhz

Intel DRAM Odd Ratio Mode enables the use of odd (as in: not even) DRAM memory multipliers which enables more fine-grain memory overclocking.

The Odd Ratio Mode feature was first introduced with the Skylake processors in August 2015 and was later removed with the Rocket Lake processors in March 2022.

When Odd Ratio Mode is enabled, the DRAM memory multiplier is offset by 1 step of either 100 MHz or 133 MHz frequency. This enables even more fine grain memory overclocking. Furthermore, it further removes the reliance on BCLK overclocking to achieve specific memory frequencies.
