Question Dual channel memory (4 DIMMS) on H670-PRO WiFi D4 (Problem)

[Lamello]

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.

There is no "quad channel". The CPU is dual channel. That is all you get.
Four DIMMs are less likely to reach high clock speed.
Were thebfour DIMMs a single set or two sets?

oh ok i see my error, so dual channel max but with four sticks... the dimms are two sets of 2x8Gb

There is no guarantee that two sets will work togather. You can try adding a couple hundreths of a volt (0.01). Since you didn't buy a single matched set you are responsible for mstching.

Now YOU have to play with it to try to get them to play nice. Matched sets are sold for a reason. The manufacturer guarantees the work as a set.
If you had asked this question BEFORE purchase, you would have gotten the same advice, and the recommendation to buy 2x16GB and sell your 2x8GB.
