Thorough explanation on RAM.
You're considering downclocking your RAM to lower latency, aiming for 3800/3866 cl16. The situation is complex with your current setup of a Z690 platform and a Gigabyte Aero G Z690 DDR4. It's important to understand how this affects performance and stability. Downclocking can improve latency but may also reduce overall speed if the new RAM isn't fully supported by your system. You should weigh the benefits against potential compatibility issues and ensure your motherboard supports the lower clock speeds. Consult detailed reviews and benchmarks for clarity before making a decision.
Review this video: The key takeaway is that faster speeds mean greater bandwidth, while lower clock rates lead to reduced latency. But since latency is expressed in clock cycles, devices with different speeds can match in latency—like a 1200MHz DDR4-2400 CL11 and a 2400MHz DDR4-4800 CL22 having identical delays. You aim for maximum speed and minimum latency, but often you must balance them. For gaming, lower latency is usually preferable. For certain productivity jobs, higher bandwidth wins.
Unless you can handle CL16 or run closer to 4000, the effort isn't worth the frustration and weeks of adjustments needed for a few milliseconds faster latency. If you're focused on competitive testing, CL16 at 4000 would be seen as insufficient. It seems the feedback you're hearing mixes opinions from casual players and those chasing top performance even by a fraction. I’d likely stick with existing settings and try a higher frequency like 4267mhz instead. That should cut down latency while using more bandwidth. Still, it all comes down to how much time and effort you’re willing to invest. If you're just playing games, enable XMP and relax—keep things stable. But if you care about FPS, prioritize VGA OC over anything else.
