Solving VRAM scheduling issues on Manli Snow Fox RTX 5070 OC
In the middle of a chaotic team fight, the game would just freeze for about 0.2 seconds. In a competitive shooter, that's basically a death sentence. The GDDR7 memory on the Manli Snow Fox RTX 5070 OC 12GB was acting up, with the memory clock jumping wildly between 1.2GHz and 2.1GHz when handling heavy particle effects. I cautiously tried dropping the resolution to 1080p, but while the FPS went up, the image looked grainy and the stutters were still there—clearly, this wasn't a raw power issue, but a scheduling one. I went into the NVIDIA Control Panel, changed Power Management to 'Prefer Maximum Performance', and used MSI Afterburner to lock the memory clock at 2100MHz. Using a frame time analyzer, the stutters dropped from four times a minute to almost zero. It's way smoother now. Locking the clock did spike my temps by 6℃ initially, but I tweaked the fan curve to hit 70% at 65℃ to keep it stable. Core temp is now 66-72℃. 3DMark stress tests confirm the VRAM scheduling is finally behaving.
