ROG x670E problem with DDR5 6000MHz memory Issue arises when using high-speed RAM modules
I built this system using Ryzen 97950x3d, Trident z ddr5-6000 with 32GB RAM and ROG crosshair x670e. It’s my first real build, but I’m facing problems with RAM speeds. When I power on BIOS and enable Expo 1, it only lets me set RAM to 4200MHz instead of the full 6000MHz. Some people say it’s a motherboard issue, but I want to check if others have similar experiences. All four RAM slots are filled with 128GB total, and the BIOS is up to date. I’ve tested speeds from 6000 down to 4200, but only 4200 works for booting. From what I read, it should run at 6000MHz with two sticks, not all four.
Hello, welcome to the forum. Please let us know your experience with booting using 2 sticks of RAM instead of 4. Also, a reminder to avoid posting PC part packaging details online, particularly those displaying S/N or QR codes, as this could be exploited for warranty claims or unauthorized distribution by malicious parties.
I'm experiencing the same problem with the same MB X670E ASUS Hero. CPU: AMD Ryzen 9 7950X3D at 16-core (4192.13 MHz). RAM: 195740 MB total, using 7777 MB. Concurrency: 32. OS: Microsoft Windows 11 64-bit (Build 26100.4652). Graphics: NVIDIA GeForce RTX 4080 via Super/PCIe/SSE2. I'm using Bios 3112 and Kingston's fury-renegade-ddr5 48 GB sticks at 6000 MHz, four in total. No issues with two sticks, but performance drops to 3600 MHz when using four sticks. Is this a problem with Kingston or ASUS? Any advice would be appreciated.
Assumption: You're working with 48 GB kits rather than 48 GB sticks. If you think this is correct, be aware that using more RAM than the motherboard supports can cause problems. Is this the Trident Z Neo for AMD chipsets? [Contains an N near the end of the model] Or does it match an Intel design? G.Skill offers two distinct versions. Verify the exact part number on their website. That detail could explain why the motherboard struggles to interpret the SPD settings for overclocking. TL;DR: You're attempting a heavy overclock, but mixing RAM from different packages plus four sticks increases stress on the CPU's memory controller. This is problematic because combining RAM from multiple kits can disrupt signal integrity. It’s generally not advised when overclocking. Four sticks place greater demand on the CPU IMC than two sticks. Also, RAM within the same package must match for best performance and stability. Electrical characteristics differ, which matters more as speeds rise and tighter tolerances become essential (especially with DDR5). That’s why G.Skill highlights this information at the bottom of their site.
