What this build is good for
This PC build features the gaming-focused AMD Ryzen 7 5700X3D and a capable Radeon RX 6800, providing excellent 1080p/1440p gaming potential. The ASRock B450M/AC R2.0 motherboard is a cost-effective choice for the AM4 platform, provided the BIOS is updated for CPU compatibility. While the inclusion of a 4TB NVMe SSD and 1TB SATA SSD offers ample high-speed storage, the memory configuration is highly problematic. Mixing different RAM capacities (8GB and 16GB sticks) and brands typically prevents stable memory training, risks boot failures, and limits system performance. The ASRock 850W PSU is well-sized for this hardware, and the Thermalright Burst Assassin cooler is an effective, compatible air-cooling solution for the 105W CPU. Overall, the build is powerful for its class but requires a standardized, matched RAM kit to ensure reliable operation and avoid stability issues common in mismatched memory setups.
- Unknown BIOS version on the motherboard
- Potential instability with mismatched RAM
- Varying physical length of RX 6800 variants

Useful next steps
Replace mixed RAM with a matched kit
Mixing RAM capacities and brands frequently leads to system instability, boot failures, or forced low-speed operation. A matched 2x16GB or 2x8GB kit is recommended.
Verify BIOS version
Ensure the motherboard BIOS is updated to the latest version to guarantee support for the Ryzen 7 5700X3D, as B450 boards may require an update.
Confirm GPU dimensions
Check the exact length of your specific RX 6800 model against the case's 320mm clearance limit to ensure a proper fit.
