Asrock x570m pro4 - 4 ram sticks problem

Hello,

Please look at below url.

Basically, if you insert 4 cards, clock is drop.
Please don't worry. nothing is broken.

General:
a) 2 single rank sticks in A2/B2 will have the most potential for high clocks.
b) 2 dual rank sticks in A2/B2 will be a bit behind a)
c) 4 single rank sticks will behave like b)
d) 4 dual rank sticks will have the lowest clock.

You have 4 d)
Your links are showing c)

It is normal, that this RAM config runs with 2933CL14.

Test the RAM with only two sticks in A2/B2, another test with two sticks in A1/B1. And then think about the 4 stick usage...

Anyway, if you want to reach 3200CL16 or 3200CL14 or higher, you obviously have to dive deeper for RAM, voltages and mainboard configuration.

Use the Ryzen DRAM Calculator and study the docu.
And take a look to the results from other users.
