5. CAS Latency (CL) and Memory Timings

CAS (Column Address Strobe) latency is a measure of how quickly the RAM responds to a command from the processor. It's expressed in clock cycles (e.g., CL5, CL6).

• Lower CAS = Faster Response: A DDR2-800 module with CL5 will respond faster than one with CL6, leading to slightly improved real-world performance in tasks like file loading, program startup, and gaming (on supported systems).
• Balance Speed and Latency: For example, a DDR2-800 RAM with CL5 has a response time of ~12.5ns, while CL6 equates to ~15ns. Though the difference seems small, it can impact system snappiness in older machines.
• Don’t Prioritize Latency Over Compatibility: While lower latency is beneficial, always prioritize matching the correct DDR2 standard and speed. An incompatible low-latency module is useless.
• Secondary Timings Matter Too: Additional timing parameters (tRCD, tRP, tRAS) also affect performance but are usually optimized by the system BIOS.

Expert Tip: After installing new RAM, enter your BIOS/UEFI setup (usually by pressing F2, Del, or Esc during boot) to confirm the system recognizes the full capacity and is running at 800MHz. If it shows a lower speed, check if a BIOS update is available or ensure both modules (if dual-channel) are identical.
