Fixing bandwidth bottlenecks for Seagate FireCuda 530 in MC RTX
With Ray Tracing on and massive chunks generating, my frame rate was absolutely diving, which honestly made me obsessed with finding the bottleneck. The 2TB FireCuda 530 was hitting 88-95% bandwidth utilization under peak load, meaning chunk data wasn't hitting the VRAM fast enough. I started by disabling every power-saving option in the Control Panel, but the bandwidth spikes were still there—that was just surface-level stuff. I eventually grabbed the latest official firmware and forced the motherboard PCIe slot from 'Auto' to 'Gen 4' mode. In AIDA64, the read speed locked in at 6500-6800MB/s, and the frame drops vanished. I did have a heart attack during the firmware update when the drive disappeared from the BIOS, but a clean re-flash and a full format fixed it. Temps are now between 54-60℃, which is perfect. System performance panels show the throughput is peaking correctly, and my frame times are steady at 5.1-6.4ms.
