How to stop bus resets on Colorful BATTLE-AX B450M-T?
Man, this motherboard is a piece of work. It decided to trigger a full bus reset right in the middle of a massive space battle, which is just great. The PCIe link on the Colorful B450M was hitting 10-25ms response gaps during current spikes, killing the GPU driver instantly. I tried killing every single power-saving option in BIOS, but then my idle power draw shot up to 80W and the fans sounded like a jet engine taking off—totally overkill. I eventually flashed the latest firmware and forced the PCIe protocol to Gen 3.0 instead of 'Auto', while disabling Link State Power Management in the Windows power plan. The dreaded 12B error codes in the system log completely disappeared, and my session time went from 30 minutes to 10 hours without a single crash. I actually bricked my BIOS for two hours during the update because of a power flicker, which was a total headache. Southbridge temps are now 55-62℃ and RAM usage is 14-18GB. Event Viewer confirms the stability, with fans humming steadily at 1400-1600RPM.
