XMP will cover that camp. This is one area where board manufacturers can secure an advantage in performance, because the sheer variety of RAM and the differences between Samsung, Micron, and Hynix chips make tertiary timings hideously complex to adjust.

Memory and board manufacturers can work together to bake-in optimal timings for popular kits, but for the most part these are determined if left on auto during POST, where they should remain unchanged unless there are boot failures.

On the user end, it can feel like trying to solve a jigsaw puzzle by shaking the box, but it works. SKILL kit in tests. When we adjusted the G. This is an extreme case, but it shows both the value of experimenting with subtimings and the frustrations of benchmarking memory.

This is the number of cycles it takes to read the first bit of memory from a DRAM with the correct row already open. Unlike the other numbers, this is not a maximum, but an exact number that must be agreed on between the memory controller and the memory. CAS Latency is the most widely talked about and compared memory timing.

This is the time needed to internally refresh the row, and overlaps with tRCD. Also known as Command Period. This will either be 1T or 2T on modern memory, with 1T being faster. Despite the unique -T notation, this is measured in clock cycles like the other timings.

If any of this would be better with a visual aid, try our embedded video above for an animated walkthrough of how some of the memory accesses work. There will be some delay after submitting a comment.
