Hey folks! I just wrapped up building my new PC with a Ryzen 9 9800X3D and I'm running into some issues while tuning the Precision Boost Overdrive (PBO) settings. Here's my setup: I'm using an ASUS ROG STRIX B850-A motherboard, 32GB of Team T-Force Delta Force DDR5 RAM running at 6000MHz CL30, and I've got a 360mm AIO cooler.
Currently, I've set my RAM to EXPO I, I'm using a curve optimizer of -30 for all cores, a boost override of +200MHz, and PBO limits of 115/90/105. Under these settings, I see peak temperatures around 76°C in Cinebench R23, performance is solid, and everything seems stable. However, when I switch the PBO limits to 'Motherboard,' I start experiencing crashes pretty quickly.
I have a few questions:
1. Why do the 'Motherboard' PBO limits lead to crashes with the 9800X3D?
2. Are the current settings I'm using optimal, or could there be room for improvement?
3. Is there any way to prevent the crashes while still pushing PBO to the max?
4. Would you describe this setup as balanced, or are there any changes you recommend?
I'd love to hear your thoughts, especially from anyone who's had similar experiences. Thanks!

It sounds like your curve optimizer settings might be unstable. Try disabling it and see how your system performs with the 'Motherboard' limit. If it doesn’t crash without it, then your -30 CO could be the culprit.
I did some digging, and it seems that on ASUS boards, the 'Motherboard' limit is essentially unlimited. The X3D chips can be pretty sensitive to power, that might be why you’re crashing. Other boards could handle the same settings without issues, which is confusing.
