Anyone knows a fix for AMD Adrenalin 23.9.2 overclock crash?

After updating my drivers to get screen recording working again (last version was 22.something and ReLive mysteriously decided to stop working) I find that whenever I try to overclock my old RX570, the whole system crashes, no matter what settings I use (even if I increase the GPU frequency just 1 MHz). Used to be rock solid for years at 1400 MHz GPU and 2000 MHz VRAM, downvolted to 1050 mV. Web search indicates it's a relatively common problem, but no workarounds or fixes.
