How to stabilize Sapphire RX 7800 XT 16G Polar OC in Sims 5?

Every time I tried to build a complex house, the game would just vanish to the desktop without a word. It's incredibly frustrating to lose an hour of decorating to a random crash. I found that the Polar OC edition of the Sapphire RX 7800 XT was suffering from a 0.07V voltage drop during peak loads, which triggered a driver TDR error. I wasted time adding 32GB of virtual memory, which stopped the crashes but introduced this awful micro-stuttering—totally a waste of time. The real fix was diving into the advanced driver settings and bumping the core voltage from 1.12V to 1.18V while aggressive-tuning the fan curve. After a 15-hour stability marathon with zero errors, the crashes are gone. The trade-off was that temps initially spiked to 78℃, but I swapped in some high-static pressure case fans to bring it back down to 66-72℃. VRAM is holding steady at 12.4-14.1GB. Stability parameters are backed up and locked in.
