The 7800X3D doesn't overclock the traditional way (locked multiplier on the cache die), but undervolting via Curve Optimizer gets you lower temps and often slightly better sustained clocks — which matters a ton in an ITX case.

I'm running an all-core -25 CO offset and it's been rock solid through Cinebench loops and a week of gaming, with a ~5-6°C drop. Some people push to -30 but I've seen reports of WHEA errors and random reboots past -25 that only show up hours later.

What offsets are you all running stable, and how are you validating — Core Cycler overnight, or just 'it didn't crash while gaming'? Curious about the per-core vs all-core approaches too.
