Question Patriot 4400 MHz memory won't set above 3600 in Asus x570 plus MB

I installed 32GB (4x8) Patriot Viper Steel 4400 MHz memory in my Asus TUF Gaming X570-Plus Wi-Fi MB. It also has an AMD Ryzen 5600x and an Asus GeForce RTX 3070 ti installed.

and Patriot Viper Steel DDR4-4400: One Speedy Serpent)

Using D.O.C.P. in the bios, the timings come automatic at the appropriate 19-19-19-39, but that automatic 4400 MHz that come up will not boot. I have to manually lower it to 3600 MHz.

Does this mean the MB can't handle the Patriot DRAM? According to this Asus document: Memory_QVL_for_3rd_Gen_AMD_Ryzen_Processors_X570.pdf , the board can handle other brands at that frequency, but this specific Patriot DRAM is not listed.

I tried it with 16 GB and I can get the frequency up to 4000 MHz, but no higher.

I'd like to be certain that this is all the speed I can get on this MB with these DRAM sticks.

An ambitious overclock and generally not recommended with Ryzen. That means decoupling your Infinity Fabric from the memory speeds. 1800Mhz is usually where that tops out, so DDR4-3600 with low latency is usually the way to go. Additionally, 4 sticks is much harder to get stable than 2 sticks.

Thanks. That's what I'm suspecting, though I didn't know those details. I got a pretty good deal on everything so I'm not too upset. 3600 is really not too bad for my needs.
