I have an Asrock AB350m Pro4 with the latest BIOS (5.50) and this ram:
- Kingston HyperX 3200MHz DDR4 CL16: https://www.amazon.com/dp/B01GCWQ80K

By default it sets to 2400mhz. I'm not an expert so using XMP profile 3200 and 3000 gives me error using windows memory diagnostic tool.

I'm afraid i'm should do oc manually but i don't know what values to use and where.
What can I do to obtain the best speed?
