Ater installing 4 sticks of 8Gb patriot steel viper 3200MHz (PVS416G320C6K) in my H670-PRO the best i can get without crashing is 3000MHz at base timings 19-19-19-43, XMP 1 and 2 crashes (bootloop or maybe 3 seconds on the desktop and crash). With the same ram in dual channel no problem, xmp 2 works flawlessly at 3200MHz 16-20-20-40. I have the latest motherboard bios and already reseated all ram sticks. How can i get xmp working in quad channel? reseating the cpu (i5-12400) is worth? Also the ram i got isnt in the supported list of the motherboard BUT i hope they add this model in the future with new bios updates considering thats a "new" motherboard.
