Cosair memory XMP confusing

So I have this kit of 16GB Corsair Vegeance RGB PRO memory CL18 3600MHz. It is rated on the website PCCG as XMP 2.0 [18 19 19 39] at 1.35V

I am running it on a x570 Taichi and a 3700X. Dual channel

The auto overclock thingy whatever AMD calls it has it running at 3600MHz 18-22-22-42 with a bank cycle time of 83. As recorded by CPU-Z @1.35V in BIOS

When I am in the BIOS, should or can I manually change the clock timings to the rated OC speeds and be happy?

does it say 18-19-19-39 in the memory kit's packaging or something? Cuz 18-22-22-42 bin is also common for 3600MHz. Possible that you got sent the wrong kit.

I did a google search on the spec number that's like 30 characters long. cmw16gx4m2z3600c18

 

On the corsair website that showed up it has tested latency of 18 22 22 42 just like it is on my PC, X570 compatable

It is the exact same numbers and letters also on the PCCG website but they show 18 19 19 39. lol

 

Here's a quote on the description of the kit from PC Case Gear's website

"Corsair Vengeance RGB Pro CMW16GX4M2Z3600C18 16GB (2x8GB) 3600MHz DDR4, 18-19-19-39, 1.35v, XMP 2.0."

blame PCCG then, maybe they can swap it or something
