[SOLVED] RAM not at the correct frequencies

[Matteo2437]

Hi, a few months ago I mounted my pc and only now I've discovered that my RAMs aren't at their correct frequencies.
They are working at 2133mhz instead of 3200mhz, so I tried to activate the DOCP profiles but the pc went in safe mode.
Every time I try to active DOCP profiles I get this message from the bios:
Performance is usually best when memory clock:FCLK is 1:1 Synch.
Maximum FCLK stability is around 1800 MHz.
Over-volting SOC May cause instability on gen 4.0 Devices.

So I tried to change the value of FCLK and put it at 1600mhz but the pc went in safe mode again.
I start thinking that my RAMs aren't compatible with my motherboard, I checked the motherboard documentations and my specific model (3200mhz F4-3200C16D-32GTZR) isn't there, but there are many similar models with different frequencies or sizes in the documentation.

Can I do something to use them at the correct frequency? or should I change them?
Thanks to everyone!

Motherboard: Asus prime X570 pro
Cpu: ryzen 9 3900x
Ram: G.Skill 32gb 3200mhz F4-3200C16D-32GTZR
Gpu: MSI Gaming X 1070
Psu: XFX 550w

The correct settings and tested speeds for your memory / motherboard combo can be found with the Memory QVL document provided on the Asus website... link:
https://dlcdnets.asus.com/pub/ASUS/...QVL_for_3rd_Gen_AMD_Ryzen_Processors_X570.pdf

Looking through that, your 32gb kit isn't listed specifically, but the 16gb version is (same code but '16GTZR' at the end) and that lists the specific tested settings used... namely 3200mhz, 1.35 volts with timings of 18-18-18-38.

These settings may not be the same as the built in profile for the ram, so I would suggest going into the advanced memory settings and inputting these settings manually.

If you cannot get the memory stable at 3200mhz, you should still be able to get it working nicely at a lower speed (say 3000 or 2933 mhz).... you can also try increasing the voltage to the memory a little more to help stabilise it if needed. Loosening up the timings may also help a bit.

Larger capacity modules, along with kits with 4 sticks can be harder to get working nicely at faster settings than a pair of smaller modules (e.g. 2 x 8gb).

Thanks for the answer, if I go on the G.Skill site I can see that the frequencies of my RAMs is different instead
18-18-18-38 it says 16-18-18-38, I haven't 4 sticks but 2. I think that the most similar model on the document is this F4-3200C16D-32GTZA but the frequencies are 16-16-16-36

I tried a couple of things, I put manually the frequencies to 18-18-18-38 with 3200mhz and the pc went in safe mode, so I tried to reduce the frequencies from 3200mhz to 3133mhz and for the moment they are working well. My question now is if a day I want to upgrade my RAMs from 32gb to 64gb buying another 2 sticks equal to the sticks that I'm using now, is it possible that I will get again the same problem with frequencies?

Adding more ram can make hitting higher frequencies harder... so if you upgrade to 64gb by adding an extra 2 sticks you may have to drop speed a bit further. It's difficult to say for sure, Ryzen is fussy with Ram.
