Should I undervolt my Sapphire RX 7800 XT to stop crashes?

It's honestly ridiculous—this card looks amazing in white, but it kept giving me a 'desktop gift' (crash to desktop) the moment I entered a ray-traced tunnel. The factory OC is just too aggressive, causing the core voltage to oscillate between 1.1V and 1.2V during complex lighting calcs, which triggers a TDR driver crash. I tried the latest Beta drivers, but that actually made it worse, crashing every 15 minutes. I finally opened the Adrenalin panel, manually dropped the core voltage to 1.08V, capped the max frequency at 2400MHz, and nudged the memory clock to 2450MHz. In 3DMark Time Spy, my stability pass rate jumped from 82% to 99%, with temps staying between 66-72℃. I tried pushing it to 1.05V, but the system froze on the loading screen, so 1.08V is the sweet spot. VRAM usage is steady at 11.5-13.2GB. I've exported the voltage and frequency maps for backup.
