I assembled a new PC featuring an i9 13900k, Z690 Force WiFi, and G.SKILL Trident Z5 RGB 2x32GB 6400MHz CL32 RAM (product ID F5-6400J3239G32GX2-TZ5RK). After turning on the XMP profile in BIOS—even just a minor adjustment from default settings—the system becomes unstable. Either prime95 causes a blue screen, or individual components begin failing due to hardware faults (such as rounding discrepancies like "0.5 vs expected 0.4"). Windows Memory Diagnostics also flags problems with the RAM. I attempted to raise the DRAM voltage to 1.48V without success. Once I lowered the RAM speed to 6000MHz CL32, stability returned. This raises doubts: is my motherboard or the RAM defective? Yet MSI lists a 6400MHz 1DPC 2R kit as supported at 6000MHz, referencing https://www.msi.com/Motherboard/MPG-Z690...cification. Does this indicate a compatibility issue or a misinterpretation? In short, I’m unsure if the hardware is faulty or if something unexpected happened.
