Ryzen 7 7800X3D paired with Skill Flare X5 6000MHz memory Performance boost available
You're experiencing issues with your Ryzen 7 7800X3D setup, specifically when trying to enable AMD Expo and set the RAM frequency to 6000Mhz. The system keeps failing to boot and displays the CPU and RAM status LEDs continuously. It seems the BIOS might need a reset to restore normal operation. Consider checking the BIOS settings for any recent changes or conflicts, and ensure all components are properly seated. If problems persist, a factory reset or consulting the manufacturer's support may be necessary.
Adjust memory parameters manually while keeping EXPO off. Configure frequency to 6000MT/s, voltage to 1.35V, and timings as 36-36-36-96 for tCL-tRCD-tRP-tRAS. This typically resolves most memory problems. If it still fails, consider a different BIOS version—it could indicate faulty overclocking support.
Training must occur even if EXPO is turned off. The system should remain operational once training completes, and the 2x16GB memory allocation should finish in roughly 30 seconds.
It's missing the point—it's not always perfectly smooth. The DRM and CPU LED might flash due to memory training, and shutting it down fixes these problems in AM5. If this is the cause, turning it off should help.
This seems to be a confusion about memory training processes. Memory training involves the CPU’s memory controller testing internal timing parameters for signaling. It helps determine how the system handles memory requirements. Sometimes you can bypass it by using previously saved settings (like Fast Boot on Intel or Memory Context Restore on AMD), but each memory configuration still requires initial training. The process doesn’t inherently cause problems; it mainly adds boot time. From what I’ve seen, JEDEC training usually matches the time taken for XMP/EXPO profiles, so delays shouldn’t be due to insufficient waiting. More likely, the issue lies with the system failing to complete memory training properly—possibly due to a BIOS bug, changes in EXPO settings, or a faulty memory stick. The best first step is to disable EXPO and gradually lower the speed until it works.
yep: I mean yeah, but sounds like memory training can be one of the culprits, since it requires collective balance of RAM compatibility, and BIOS compatibility. Which already climbs the edge of the fence the higher clock speed and lower timings you have.
This scenario is entirely different. The system actually starts with EXPO enabled, allowing memory context restore. This isn't the case here—the system won't start, so memory context restore can't provide any values. "Disabling memory training" isn't feasible unless you've already completed the training process (on AMD you must do it; on Intel you might bypass it by tweaking settings or frequencies, though stability drops significantly). The issue isn't a memory training failure; it's about the system not recognizing previous settings and thus can't skip the process.
the system in post didn't incorporate EXPO. my advice was to keep memory training active; i usually wait a few minutes to see if it boots or if the issue resolves, and only disable it if that doesn't happen. alternatively, you might consider updating the BIOS.
MSI boards consistently apply identical training configurations regardless of whether EXPO is active or inactive. This means the boot process will always take the same duration whether training is enabled or not. As long as they pause for the same period during initial startup, it provides sufficient time to assess whether the issue lies with the training process itself.
