RAM (memory) timings are complicated. Primary, secondary, and tertiary timings can impact benchmark performance on Intel and Ryzen CPUs, and we talk about them here.

In this content, we define different memory timings and talk about the ratios between timings. Primary timings are focused on today, including CAS Latency (CL), tRCD, tRP, tRAS, and more. We also talk about command rate, and provide some benchmarks with tRFC and tREFI testing for memory overclocks on an 8700K CPU. Memory timings impact performance on Intel and AMD similarly, though the first round of Ryzen CPUs were particularly sensitive to memory timings. This brought timings back to the forefront of everyone’s minds, and we’re here to explain memory timings and what they do. A future content piece will talk about secondary and tertiary timings, but we are focusing on primary timings for now. This applies to Samsung, SK Hynix, and Micron memory alike, which is used by all the vendors (Kingston, GSkill, Corsair, etc.).
