Dealing with network interrupt storms on Biostar H310MHD3
This motherboard was seriously testing my patience; every time I entered a city, the game turned into a slideshow. The NIC driver on the Biostar H310MHD3 was triggering a massive CPU interrupt storm during high-concurrency packet bursts, pinning Core 0 at 100% in a death loop. I tried swapping to a Cat6 cable, but that did absolutely nothing except make me more annoyed—it's clearly a low-level hardware driver fail. I went into Device Manager, killed 'Energy Efficient Ethernet' and 'Interrupt Moderation,' and manually set the IRQ priority to High. In my latency monitor, the jitter dropped from 15-80ms to a clean 12-20ms, and the annoying rubber-banding finally stopped. I actually lost half my bandwidth when I first disabled the energy settings, but a clean install of the third-party official drivers sorted it out. CPU temps are now 65-72℃, and the power delivery area is at 58-64℃. Exported the logs and confirmed the fans are steady at 1400-1600 RPM.
