A-XMP causes a black display and DRAM activation in an MSI B650M-A Pro using Corsair 6000mhz RAM.
Hi, just completed the build and am now working on configuring the BIOS before proceeding. The issue started immediately after turning on A-XMP and rebooting—only a black screen appears and the DRAM light stays on. After running it for about half an hour, nothing changed except a BIOS reset to restore it. My motherboard is an MSI B650M-A Pro Wi-Fi with a Ryzen 7 7800X3D CPU, two Corsair 16GB 6000MHz C30 RAM sticks on A2 and B2, and a Radeon RX 6700X GPU. The PSU is more than sufficient, so voltage isn’t the problem. There’s no visible issue until I enable A-XMP; only manually setting the frequency to 5000MHz after it worked again caused the same problems. Trying RAM on A1/B1 didn’t help. The BIOS is running the latest non-beta version. It also triggers the CPU red LED when I power off while stuck in permanent DRAM mode, and turning it back on without resetting the BIOS causes issues. I’m confused about what’s going wrong. Should I switch to EXPO RAM? Is this a motherboard fault? Could my CPU not handle 6000MHz RAM? Overclocking manually didn’t fix it, and power-down with memory context restore didn’t resolve it. I’m getting really frustrated. Have others faced the same problem and found a workaround besides swapping RAM? ETA: completed two passes of MemTest86 with no errors. Also verified CPU integrity and checked all PSU connections.

I’d upgrade to an overclocked RAM and choose a package with a capacity of 30 or 32 rather than 36. The performance is solid.
You mentioned earlier you had CL36, now it shows CL30. Was there a mistake with the RAM type? It seems the CL36 model could cause problems if used incorrectly. Updating the BIOS might be the best solution. Some AMD updates have memory support issues, and XMP settings don’t seem to be the problem either. The motherboard should handle AM5 chips fine for DDR5 6000, though. I’d lean more toward a BIOS issue than anything else, but the memory kit itself could also be the cause.
Hi! Thanks for your message. It looks like there was a small mistake in the post. After reviewing, the RAM you have is the CMH32GX5M2B6000C30, which matches the MSI QVL list for this motherboard. You're using the latest non-beta BIOS (7D77v1O), and since you've completed 7 passes of memtest86 with no errors, it seems your RAM is in good shape. The issue likely isn't hardware-related. Rolling back to an older version might not be necessary unless you suspect a specific bug.
I’d probably try giving an older BIOS a chance to observe its behavior. I wouldn’t rely as heavily on it as you do. From my experience, MemTest86 isn’t the best tool for spotting memory issues compared to other stress tests. It works, but it’s not outstanding. I’ve seen many configurations that seemed okay in testing but failed under real conditions. Also, the XMP profile might be problematic—rare cases exist where stable kits fail when using XMP settings. After updating the BIOS, I’d inspect each memory stick separately to determine if both support XMP or if only one does.
I switched the BIOS to an older release but it still failed. After checking both RAM sticks using XMP settings (previously only done with default), it turns out just one prevents booting while the other works fine without any adjustments. This is the first time I encounter a RAM stick that only works with XMP enabled—hopefully this helps. I’ll reach out to Corsair for an RMA of a working unit and will run 16GB at most until then. Thanks for your guidance!
