Looking for a 3600Mhz DDR4 motherboard. I’m unfamiliar with CL values except that lower is preferable. Which sequence matters most—18-22-22-42 or 19-20-20-40? Thanks in advance for your advice.

Usually Intel prefers the earliest clock speed, while AMD favors slower timings. But neither is ideal—at that stage a 3200MHz chip with speeds around 16-18-18-38 would be better.

The first factor matters most, though the performance gap between options is only about 0.05%. It's not worth getting too concerned.

It seems you're looking to understand more about the trade-offs involved. You want to know when reducing your upload speed can actually help boost your content quality.

The 3200 16-18-18-38 offers slightly quicker secondary speeds compared to the 3600 18-22-22-42 while maintaining a similar clock speed. This means the 3600 might still be a solid choice, especially since the timing differences are minimal overall.

Your ECC memory type is 9-9-9-24, but your system uses DDR3. This mismatch can cause compatibility issues. The reason DDR4 might seem slower isn't necessarily about speed—it's often due to differences in architecture and support for older standards. Modern DDR4 offers better performance overall, but it won't work with DDR3 modules.

The times depend on the frequency. You must perform calculations to determine the actual delay in seconds.

DDR4 operates at higher speeds but needs more time to prepare for sending or receiving data through the contacts in the memory module... this is the CL latency... it’s the delay from when a request arrives until the RAM can actually send or receive data in bursts to the CPU. This effect is noticeable only with programs that handle large amounts of tiny data packets, since each transfer requires some initialization time. Once active, it performs quickly at its advertised rate. In games dealing with big data files like textures, audio, and level information, this latency has minimal impact. For databases or other heavy applications, lower latency becomes more important. With Ryzen processors, prioritize frequency, then aim for a lower CL value—but don’t worry too much about it. Any difference from CL adjustments is likely overshadowed by overclocking the RAM to higher speeds.
