This MSI MPG X870E with Carbon WiFi supports Ryzen 9 9950X3D but doesn't work properly in dual-channel mode.
I recently installed a new PC and am facing problems starting it up after enabling XMP/EXPO. The RAM only reaches 5600MHz during memory training, but the system freezes and won’t boot. I’ve used two 64GB Corsair DDR5 kits at 5600MHz with MSI MPG X870E Carbon WiFi, paired with a Ryzen 9 9950X3d, and it works fine without XMP enabled.
You're asking about the duration of a process, specifically running 4x32GB.
They mentioned the Part might refer to 4x64, but if memory holds (no joke), AM5 can't handle it generally.
The setup holds 128GB across four 32GB drives, and everything was placed in the right slots on the board. I kept it running for roughly half an hour to work on memory training. The CPU overheated significantly during operation; after I stopped and restarted, I accessed the system and found the temperature reached 90°C within about thirty minutes of continuous memory training.
It seems there are several issues here. The system appears to have performance problems, especially with slow CL40 timings on a 5600 kit. The recommended configurations would be more reliable, such as 2x48GB or 2x64GB instead of the 4x32GB options you're seeing. These lower-end kits often struggle with speed and stability. Despite the poor timing, the price is attractive—96GB for just $160 is quite a deal. The build quality is questionable, but the memory specs are decent for the cost.
CPU stays idle near 45°C, reaching 75-80°C during heavy use. Under BIOS operation, fans run low, which might explain the temperature spike after memory training.
Occasionally the pins linking RAM to memory controllers on the CPU aren’t forming a solid connection, which can cause issues like instability or missing channels. This often happens when the CPU wasn’t thoroughly checked in the socket or on its back before installation.
