B850M-X: no manual/advanced curve optimiser£

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   So, the only way I can see that I am able to set any CO adjustments is through a series of performance presets - but they start at -20 and beyond which is too much for my CPU and causes instability. I?�d like to try -15 and -10 but it seems that there is nowhere that I?�m able to manually set these adjustments. 

Also, I have no control over the thermal throttle limit / max cpu temperature (dropping from 95C to 85C on basically all of the presets available). 

Is this motherboard really so limiting?? Or am I missing something?

	It says version 3.15 When i go into Advanced Tab, AMD Overclocking > Precision Boost Overdrive It only lets me set auto, disable, or enable. Selecting enable doesn?�t give me access to any additional settings either.

	Same issue here. My own machine (9800X3D, Steel Legend B650) shows all the settings on bios 3. 15, 20 and 25 no problems at all. My Dad's machine I'm building (7600X, B850M-X WiFi R2.0) does NOT show anything under the PBO (tested .15 as stock and .25) .... just Auto, Enabled, Disabled. Most confusing.
