A-XMP setting leads to different RAM configurations being detected.
A-XMP setting leads to different RAM configurations being detected.
Hello, I've noticed frequent BSODs when the A-XMP profile runs. Previously, I used a 60 Hz 4K monitor, which wasn't too taxing on the CPU. Now I'm switching to a 165 Hz screen. It's unclear if the change is the cause. I've experimented with two RAM modules, adjusted timings and voltages manually using the Ryzen Drm calculator consistently. Anything above 2444 triggers BSODs. I've reformatted my PC, updated BIOS, Windows, drivers, chipset, etc. It seems unrelated to Windows issues either. I removed and reinstalled all components again. Temperatures stay within safe ranges—CPU runs 60-65, GPU maxes at 63°C, PCH and MSI at about 45°C. I tried adding a fan over the RAM sticks but it didn't help. One RAM is Samsung B-DIMM and the other is C-DIMM; I suspect the C-DIMM might be problematic. Both kits are causing BSODs. I've tested one RAM at a time, changed connectors, runmed Memtest overnight. I'm wondering if the motherboard itself could be the culprit. Thanks for your assistance. My system specs: Ryzen 5 3600 @ 4.2 GHz (no overclocking), MSI B450 gaming board, Kingston Hyperx Predator 16GB 2x8 at 3200 MHz, Corsair Vengeance LPX 2x8 at 3000 MHz—each tested separately.
Unless you're incredibly unlucky and made terrible choices, I think it's likely the motherboard is the issue.
It could work well. The MSI B450 Gaming Plus isn't known for excellent memory overclocking capabilities. Given the advertised 3466MHz spec, the memory layout and shielding might not be ideal. Still, a 3000MHz DOCP overclock seems manageable for both the board and its controller. Before sending it back, consider these points: Have you upgraded the BIOS? Are the memory kits available for that model?
Hey, I've checked updating the bios and tried older versions too. Both kits are listed in the QVL. Regarding the CPU, it doesn't seem to be the issue—no overheating and stable BSOD while A-XMP is enabled after gaming sessions (10-30 minutes). Turning it off fixes the problem right away. I'm guessing the motherboard might be the culprit. Finding a decent CPU at a reasonable price should be tough.
You're likely correct, but remember other B450 boards are available for much higher frequencies. It's improbable the processor is the problem unless its memory controller is unusually poor. Usually, if the CPU was the concern, crashes would occur even without XMP enabled.
