So my Foxconn G41MXE/G41MXE-K have this thing that looks like a CMOS clearing heads but it’s written “MEM_OC 1333”

So I tried to use a 1333mhz ram stick but it didn’t work
I tried to change the jumper position, and even removing it but nothing have changed, the bios doesn’t even allow voltage changing or more than 800mhz and the manual doesn’t have this mem_oc thing
