I recently built a new PC and have encountered random BSODs with a 'MEMORY_MANAGEMENT (1a)' error whenever I enable EXPO. My system seems stable without it, running at JEDEC speeds. I'm seeing a bugcheck `0x0000012B`, indicating a hardware memory error, specifically with the process 'MemCompression' mentioned in the crash log. I've updated all relevant drivers and confirmed stability with quick tests at JEDEC speeds. Now I'm trying to figure out if the crashes are due to early AM5 issues with EXPO, the need for manual adjustments to SoC and DRAM voltage for DDR5-6000 stability, or if I should consider replacing the RAM since I'm still within the return period. Here's what I'm working with:
- **CPU**: AMD Ryzen 9 9900X
- **Motherboard**: ASUS Prime X870-P WiFi (latest BIOS)
- **RAM**: TEAMGROUP T-Force Vulcan DDR5 32GB (2x16GB) 6000 MHz EXPO
- **GPU**: ASUS RTX 5070 Ti TUF OC 16GB
- **Cooler**: Thermalright Phantom Spirit 120 EVO + PTM7950 pad
- **PSU**: Corsair A1000GLS PCIE5
- **OS**: Windows 11 Pro 64-bit
I'd appreciate any insights or shared experiences on tackling this issue!

I'm leaning towards ASUS hardware being the issue. They often have quirks that might not be immediately obvious when you first set things up. I wouldn't be surprised if the motherboard is the source of these crashes instead of the RAM. Just saying from my experiences with ASUS.

I get what you're saying. ASUS has burned me before too. My ROG laptop was a nightmare. If I can't stabilize the system soon, I think returning the ASUS board (and possibly the GPU) might be my best bet.
