I recently assembled a new system: R9 7950X with 32GB DDR5 RAM, paired with a B650 Edge Wi-Fi motherboard. All components matched the QVL specifications. I swapped out the RAM, motherboard, power supply, CPU, and even the SSD. Despite these changes, my machine consistently fails Memtest86, and I experience endless blue screens in Windows plus unstable performance on Linux Mint. I’m completely unsure what might be causing this issue. I’ve tried everything—running one RAM stick at a time, testing various USB drives with updated Memtest images. It’s like no one, not even Linus, could figure it out.

No, I did not check the BIOS status. Please confirm if you'd like assistance with that.

EXPO/XMP is activated. The exact RAM model isn’t specified, but the kit is compatible with the QVL. Performance can vary based on CPU IMC quality, even if the kit appears in the QVL.

I updated the latest BIOS, but unfortunately I didn't succeed. This was for my first and now second motherboard.

I performed the test without using an EXPO and checked the RAM's clock speed. The model is the G.Skill Trident Z5 NEO, which has two sticks.

Check the connections, reset the CMOS, and allow the MEMS to recalibrate.

I used the silk-screened RAM slots visible on the motherboard. I also attempted to reset my CMOS, followed another tip about setting UCLK=MEMCLK, which seems a bit more reliable, but the latest test showed 496 errors. It’s not stable enough for continuous use yet.

It might be necessary to return the defective DIMMS items.

It seems the issue isn't hardware-related but possibly tied to a newer AM5 model with recent instability. It might be best to wait for updated BIOS releases or consider sticking with the more stable AM4 setup. I’ll keep an eye out for any improvements and let you know if anything changes.

Additionally, there was once a caution in Memtest X64 advising against running cores in parallel tests, though it's unclear if this issue has been resolved.
