Issues with AMD Ryzen 4 DIMM RAM at 3600 MHz
Hello friends, I own a 4 GSKIL F5-6400 - TZ5RK RAM with a combined capacity of 128GB across four slots. My processor is a Ryzen 7950X3D and I use an Asus TUF x670e Pro motherboard. The system runs smoothly with two RAM slots, but when I add all four slots the RAM clocks up to 3600MHz and the boot time becomes very slow. The most recent BIOS version is from November 10, 2024. What adjustments can I make to improve this? Your assistance would be greatly appreciated. The RAM clock speeds are displayed in the picture, showing two RAM modules installed on the board.
This design is typical and explains why many people think DDR5 motherboards without four RAM slots are better. It limits memory speeds to around 3600MT/s, which comes from how the memory layout interacts with more sticks and the controllers' capabilities. Using four slots isn't ideal unless you really need extra capacity—otherwise, it doesn't significantly affect performance. If speed matters, sticking to two sticks is the smarter choice.
Yes, some manual tweaks can improve performance slightly, but reaching DDR5 6000 is nearly out of reach. Also, attempting this usually causes instability and memory issues, which you'd rather avoid, especially since high-end configurations often require 128GB RAM without any signs of problems. They claim a speed of 3600MT/s, yet the screenshot shows 3200MHz—this suggests they understand DDR details, particularly because only two slots were visible in that image (confirmed by the detected 64GB).
You can observe from the attached image that both RAM slots are functioning properly. With four RAM slots, the performance decreases to 3600mhz, and it repeatedly brings me back to the BIOS screen, which is a significant issue.
Yes, using four sticks on DDR5 is quite recent even a couple of years back. The first Ryzen models supporting DDR5 RAM were around 7000. BIOS typically disables EXPO when you run four sticks. You can attempt to run EXPO and adjust the frequency between 6000-5600Mhz.
