I have a 10850K in a SFF casevand and wish to undervolt it while keeping it at stock settings. I know about undervolting GPUs where voltage is adjusted, but in my BIOS (MSI Z490I Unify) there are many settings that confuse me about what should or shouldn’t be changed.

I understand the core ratio should be set to 48 (4800Mhz), but I’m unsure about the core ratio mode and ring ratio. My board offers adaptive, offset, override, and another setting. Should I apply a negative offset and keep reducing from there? Are there other factors I should consider? Honestly, I have no clear direction. Thanks.

If manual OC isn't being applied, employ negative voltage offset. This should reduce voltage by that extent across all operating conditions.

Don't attempt it, it's not worth trying.
You'd need to reduce the offset and repeatedly run a complete software suite to identify when crashes begin, since each program has its own voltage requirements and you must test everything regularly.
Avoid setting your CPU to 4.8 across all cores, as this will only reduce performance.
For power savings and lower temperatures, adjust TDP settings instead.
Only monitor vcore if you observe excessive usage by your motherboard.

The VR VOUT frequently reaches 1.3V. Would adjusting the negative offset instead be a viable solution?

Just keep the default configuration on stock and lower the voltage offset gradually.

1.3 is acceptable under heavy load. You may reduce only that part, though I noted you could face unexpected crashes due to other software issues.

Played Overwatch and achieved 1.335V with a peak temperature of 74°C. It's not terrible, but I'd prefer standard settings plus cooler temperatures. I plan to experiment with the offset.

The turbo mechanism can enhance a few cores as required. Adjusting the maximum CPU usage in Windows allows it to remain below the standard 100%.
