Why is my Manli RTX 5080 OC stuttering in Delta Force?
During massive battlefield pushes, I noticed the memory throughput suddenly tanking by 12% - 15%, which sent my frame generation time at 4K skyrocketing from 8ms to 22ms. This Manli 5080 OC uses the latest GDDR7, but under high-frequency OC loads, voltage fluctuations in the memory controller cause tiny clock slips. I initially tried downclocking the core to gain stability, but that was a total waste of time—I lost about 12 FPS on average without actually fixing the stutters. I eventually used MSI Afterburner to nudge the memory clock offset to +200MHz and forced the Power Management Mode to 'Prefer Maximum Performance'. Monitoring via RTSS showed the frame time variance tighten from 8-22ms down to a rock-steady 7-11ms, and the screen tearing just vanished. It wasn't a walk in the park, though; I hit two driver resets during the first few tweaks until I added a small 0.025V core voltage compensation. Now, core temps sit between 62-68℃ with fans humming at 1600 RPM. Benchmarks confirm the memory scheduling curve is finally flat, keeping frame times locked at 7-11ms.
