How to fix VRAM thermal throttling on Sapphire Polar?

I dug into this and found the VRAM temperatures were swinging between 72°C and 78°C, which basically choked the instruction cycles. I started by using Game Performance Assistant to force memory recovery, with a dynamic swing of 2.1-2.8 bytes, but the stuttering was still there. Then I brought in HWiNFO to track the package temp and saw 68-74°C jumps causing clock drops. I went into the CPU-Z and MSI Afterburner to undervolt the curve by -0.050V, which managed to keep the heat peaks between 71-75°C. Suddenly, the ability chaining felt buttery smooth again. I topped it off by cranking the fan curve to 80% and verified the load balancing via 3DMark. Turns out, just clearing cache is a joke; you need a combined hit of undervolting and aggressive cooling to actually stabilize the frame pool.
