How to fix VRAM fluctuations on Manli Snow Fox RTX 5070?
While exploring the jungles, I noticed the VRAM clock was bouncing between 18-22Gbps. It wasn't hitting the thermal limit, but the instability was causing the core clock to jitter. I tried killing every background process in Windows, but the FPS just hovered between 55-62 without any real gain. I went into the driver settings, switched the memory clock from Auto to Manual, and set a steep ramp-up at 75℃. My monitoring tool showed VRAM temps stabilizing at 68-72℃, and frame times tightened from 9.8-13.1ms to 7.2-8.5ms. I actually tried bumping the voltage first, but that sent the temps screaming toward 85℃; it took two reboots and a rollback to realize stability is more important than raw speed. The fan noise is a bit coarse at max speed, but the cooling is legit. 3DMark now shows the GPU idling around 62-67℃.
