i have gskill 3600 16 19 19 35 and it runs only 2133 instead of 3600 even after DOCB on MB asus tuf x570 gaming plus
this, the bios should have either a XMP (extreme memory overlock setting you can find from the MAIN page) or it should allow you to clock the ram at the proper speeds in the tweaker section of the bios.Look in Ai Tweaker for Dram Frequency and set to 3600 then save and exit
On Asus MBs it's called DOCP, enable it and choose proper frequency.i have gskill 3600 16 19 19 35 and it runs only 2133 instead of 3600 even after DOCB on MB asus tuf x570 gaming plus
