The advice about exceeding 6000 MHz RAM with AMD chips is generally accurate. Higher frequencies can lead to stability issues, so sticking to recommended limits is wise. Choosing 6200 MHz over 6000 MHz might offer better performance if your system supports it.
Some motherboards come with updated BIOS that support speeds exceeding 7000MHz, reaching up to 8000MHz. However, if you're not keen on adjusting RAM settings, you probably won't hit those speeds just by turning on EXPO or XMP. Speeds around 6000MT/s or 6200MT/s offer little change. It's more likely you'll achieve 6200MT/s with a new BIOS, while 6000MT/s is a more reliable choice.
The ideal setting lies around 6000, with 6000CL30 or 5600CL28 being the best options. Going beyond that may require adjusting the 2:1 ratio for higher frequencies.
This was accurate until recently. It wasn't inherently bad—it simply lacked adequate support. G.Skill is now offering 48GB kits with 6400Mbps memory and EXPO profiles, effectively removing that restriction. https://www.newegg.com/g-skill-48gb/p/N82E16820374521 https://www.newegg.com/g-skill-48gb/p/N82E16820374522 If you need more than 32GB and require a reliable package, these options are likely solid choices.
Recent agesa updates suggest most single CCD modules (R5 and R7) can handle 6400 full-speed operation if you adjust SOC/IOD settings and memory timing. For a straightforward setup, 6000 works perfectly without changes, while 6200 may function smoothly with minor tweaks. Two-to-one mode is only practical on R9 chips, which better leverage the increased bandwidth from faster memory speeds like 7200+.
It's a bit tricky if you just want to turn on XMP/EXPO. Stick with 6000 CL30/32 for optimal results without extra work. If you plan to fine-tune it manually, higher clock speeds can help offset the slower latency in 1:1 mode. Remember that Ryzen 7000 supports two memory controller settings—1:1 and 2:1. The 1:1 mode offers much lower latency, though you can compensate with very fast clocks. By default, CPUs with DDR5 6000 or lower run in 1:1, while those with DDR5 6200 or above use 2:1. Most should handle 6200 in 1:1, some 6400, and a few 6600 if conditions are right. Using 2:1 mode drops performance significantly until you reach around 7600MT/s, after which it loses ground compared to 6000 CL30. Higher speeds maintain the edge.
Achieving those speeds requires adjusting the gear ratio from 1-1 to 2-1, which generally makes them slower compared to lower clocked RAM. The original poster might be able to reach 6200MHz on an Am5, though this isn't certain. Running at 6000MHz CL30 is currently a popular choice, but if the cost isn't high, you can try 6200MHz and switch to 6000MHz if stability issues arise.
