Consider purchasing the kit at 4000MHz or upgrade your RAM to match? Both options are viable depending on your needs.
Maintain stability at 3600 Mhz, aligned with your 5800x Infinity Fabric. Consider shifting to a range of 3650-3700-3733 while keeping it in sync with the CPU's Infinity Fabric. Avoid overloading the DDR4 controller with 1.55V; 1.35V is sufficient and better to stay below 1.4V.
These are essentially top-tier BIOS chips, not everyday purchases. They’re built for high performance, often exceeding 4200 MHz, and are designed to handle demanding workloads. You already have solid RAM modules and decent storage options, so focus on tuning the clock speeds—typically between 3800-4200 MHz (adjusting for your system’s clock frequency). Pay special attention to timing details like TRFC and SR DR DD, which significantly affect performance. The CPU voltage is usually not a major factor since these chips are built to tolerate higher voltages without damage.
You can generally ignore the CPU voltage regulation unless you’re experiencing instability, in which case you might need to adjust the VDD levels. The main focus should be on optimizing timing settings, especially for the memory controller and other critical paths.
For stability, ensure the RAM stays below 1.7V to protect the IC and above 1.75V to maintain good performance. Running a maximum memory capacity is usually safe, as long as it doesn’t exceed your system’s limits.
If you’re unsure about timing optimizations, watching detailed guides on RAM overclocking can help. Some users have successfully pushed these chips to 1520 MHz or higher with careful profiling and tuning, though it requires patience and testing.
Ryzen features an infinite fabric, acting as the communication pathway between CCDs (when multiple exist) and the I/O die. The infinity fabric clock (FCLK) needs to match the memory clock one-to-one, typically requiring a RAM speed between 3600-4000 MT/s for a maximum FCLK of 1800-2000MHz. It's uncommon for Zen 3 to maintain stable operation at a 2000MHz FCLK, so buying 4000MHz RAM usually means either downclocking or using a 2:1 scaling, which reduces performance. Generally, it's better to invest in a 3600MHz kit and try to push the FCLK higher, as demonstrated by my experience. I achieved 3800MHz with a 1900MHz FCLK on my 3600MHz board, though the chip hesitated above 1900MHz. Adjusting further would require more effort and precision.
