OC refers to Overclocking, which is adjusting a component's speed beyond its default limits to improve performance.
OC refers to Overclocking, which is adjusting a component's speed beyond its default limits to improve performance.
The specs indicate a dual-channel DDR4 RAM configuration with speeds ranging from 3600 to 3466 MHz. The numbers after the comma represent the base clock speeds in MHz, while the following digits show the actual effective speeds (O.C.) at different frequencies. This means you can expect stable performance around the listed speeds, but actual speeds may vary slightly depending on the frequency used.
For optimal performance with this motherboard, aim for RAM speeds within the range of 3200–3600 MHz, preferably matching the base clock of the slots (usually 3200 or 3600).
This indicates the motherboard has been validated for those increased frequencies, though the official limits aren't officially reached. For instance, Intel's 9900KS processor is designed to work with DDR4-2666, meaning anything beyond that would be considered overclocking. Likewise, AMD CPUs in the 3000 series typically handle up to 3200Mhz, but real-world performance often exceeds this. Zen2 chips (most in the 3000 lineup) usually sustain speeds around 3600Mhz or higher.
