How to losen ram timings?
I'm overwhelmed by the numerous factors to evaluate. It's hard to decide which adjustments would simplify the post-Sys setup mix of a 3000MHz CL15 x2 and two 3600MHz CL18 units, paired with an Asus B350F and a 5600Docp. Windows handles it well, but auto settings around 3200/3000 seem to work too.
Share the burner screenshots for all four sticks. Random tweaks without knowing the IC limits will take much longer than when you understand what the ICs can do and adjust properly. CPU-wise, zen and zen+ have limited ICs—around 3000 is typical without tuning or tools like micron rev e. Zen2/3 can reach 3800-4000 for a 1:1 setup, while Cessna APUs might handle ~5000 with proper settings.
Generally, aggressive clock speeds are easy to get into unless they're extremely close to breaking. Based on my experience with AM4 boards, a fixed timing configuration will either work or fail, rarely do you encounter retraining loops that eventually reach Windows, and stability problems usually follow. I’d begin by applying the XMP profile from the 3600 kit, perhaps adjusting each primary clock by about two ticks if the CL15 kit struggles with 3600. If long startup times persist, the frequency itself might be the root cause—consider setting SOC voltage to around 1.15V and ensuring GDM is active. Adjusting ProcODT settings could also help, especially for higher frequencies on older AM4 boards.
Thank you. I'll wait a few days to try it out. For long shutdown, the SOC voltage should be around 1.15V instead of the default 1.35V. Values between those ranges work best for ProcODT. Higher or lower isn't ideal.
The 1.35V SOC voltage range can harm the CPU over time, so keeping it below 1.2V on Ryzen 5000 models is advisable. These components generally perform best around 1.1 to 1.2V, and a value near 1.15V should suffice for most chips. It’s worth checking the VCore reading instead of just the SOC voltage, as most motherboards set it to 1V at 3600. The optimal setting depends on various factors, so starting around 40 ohms and adjusting may be necessary. Older boards might do better with a slightly higher resistance, between 60-80 ohms, but I’m unsure how your specific board handles that.
