I've just finished building a new PC and want to make sure I'm not missing any useful setup or optimization steps. My previous system had a Z370 motherboard, Core i5-8600K, GTX 1070 Ti, and 16GB of DDR4 memory. The new system uses a B850M motherboard, Ryzen 7 9800X3D, RTX 5080, and 32GB of DDR5 memory. I'm especially interested in current best practices such as BIOS updates, memory tuning, undervolting, fan curves, driver setup, and other safe ways to improve stability, temperatures, or performance. I've been out of the PC hardware scene for a while, so practical advice for getting the most out of this build would be appreciated.

For the memory, enable EXPO first and test that the system is stable. Manual DDR5 tuning is possible, but the gains are usually modest and it can take a lot of troubleshooting if the settings are too aggressive. Also set a sensible fan curve, check that the GPU power connector is fully seated without sharp bends near the plug, and monitor temperatures during normal use. If everything is stable and cool, there’s no need to tweak it just for the sake of tweaking.
Undervolting can be worthwhile, especially for the graphics card. It may reduce power use, heat, and fan noise while keeping nearly the same gaming performance. Make one change at a time and test it with demanding games or a stability benchmark. For the CPU, avoid blindly applying aggressive overclocks; the 9800X3D generally benefits more from sensible temperature and power settings than from manual frequency tuning.
Since the system is already assembled, start with the basics: update the motherboard BIOS, install the latest chipset and graphics drivers, enable the correct memory profile such as EXPO in the BIOS, and confirm that the RAM is running at its advertised speed. Then check temperatures and stability under a few games or benchmarks before changing anything else. The 9800X3D and RTX 5080 are already very high-end, so tuning is optional rather than necessary.
Thanks, that’s the kind of checklist I was looking for. I’ll verify the BIOS, drivers, and memory profile before experimenting with performance tweaks.
