What would be the best setting for these two 8 Gb moduls with an Asus Tuf Gaming Z590 board, if I want to OC but not into risky territory ?
Cpu is i5-11500. Just to give an idear: Asus states that HuperX HX451C20PB3K2/16 can run with 5133 MHZ with that CPU.: Timing 20-28-28-48 and 1,55 v.

The sticks are rated XMP profile 5133Mhz.

However the processor won't do it.
System Agent (IMC voltage) is locked.
Then there's the motherboard. What is it?
OEM, you get what it lists in the QVL and that's it.

GL!
