Latency Timing

The information below will help illustrate the various settings that can be adjusted when setting the memory timings in the motherboard BIOS for optimum performance. Please note that these settings may vary depending on motherboard make/model or BIOS firmware version.

Sample

tRCD

tRP/tRCP

tRA/tRD/tRAS

CAS Latency (CL): Delay between activation of a row and the reading of that row.

RAS to CAS or RAS to Column Delay (tRCD): Activates the row

Row Precharge Delay or RAS Precharge Delay (tRP/tRCP): Deactivates the row

Row Active Delay or RAS Active Delay or time to ready (tRA/tRD/tRAS): Number of clock cycles between activation/deactivation of row.

Disclaimer: All Kingston products are tested to meet our published specifications. Some systems or motherboard configurations may not operate at the published Kingston memory speeds and timing settings. Kingston does not recommend that users attempt to run their computers faster than the published speed. Overclocking or modifying your system timing may result in damage to computer components.
