Is the memory configured correctly?

Hello all.

I bought a new PC and I would like to know if it is correctly configured to use the speed that the RAM I got can provide via XMP.


  • ■ Motherboard: AB350M-DS3H
    ■ CPU: Ryzen 2700X.
    ■ RAM: Evo Potenza (Model GPR416GB3000c16asc).

Anyway, this is a photo of the BIOS and I would like to know if:


  • ■ The memory I have installed seems to be a 3000MHz stick.
    ■ It is operating a 3000MHz.

Thanks!

Update: I found the memory here. It says that for AMD I should get a different one. Wondering if it matters as well. But this is other question, the main one is above.

Thanks for the reply.

Using Linux / Ubuntu 18.04.1 LTS. This is the relevant output of "lshw" and it seems that the RAM is running at 2133MHz :/ I'm not used to fiddling with this and it's a bit frustrating that it didn't come correctly configured from the shop. So, we can confirm it's not correctly configured, right?

Wondering what I should do. I think these readings are not OS-dependent. I guess I should go to the shop and ask them to configure it correctly since it's still under warranty. I think I should also run CPU-Z but I don't have a Windows license, I read:

*-memory

physical id: 26

*-bank:0

BTW, the BIOS manual says: "Memory Frequency (MHz)" : The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the System Memory Multiplier settings.

XMP is memory profile written in the memory controller on the RAM stick which BIOS should read and set all parameters according to it.
So you have BCLK 100 x Memory multiplier 30 = Memory frequency 3000MHz but it 's showing 2133 which is actually base frequency for DDR4.
Seems that Linux is reading XMP and JEDEC values from RAM instead of actual settings.

I managed to run CPU-Z and I got a report. What do you think? I hope to learn from this one :)

Yes, it wouldn't be dual channel if it was in wrong slots. Also that RAM has only one XMP memory profile.
There are couple of programs to help with RAM.
Thaiphoon Burner http://www.softnology.biz/ to find more details about RAM
Ryzen DRAM Calculator 1.3.1 https://www.guru3d.com/files-details/download-ryzen-dram-calculator.html to see possible adjustments.
Ryzen_Timing_Checker https://www.techpowerup.com/download/ryzen-timing-checker/ to se more details about present settings.

I checked in the BIOS and there is no profile 2, and setting the multiplier manually to 30 shows the same as profile 1... (as in the first image I posted). Weird...

You don't set the multiplier
You set the ram frequency tab.

Set it to 2666

I think the issue is the board is going through boot at 3000mhz, failing then,dropping ram speed to ddr4 base speed (2133)

As I said it's unlikely youll run 32gb at 3000mhz

I was checking that tab, anyway...

Set it to 2666 and worked. The text in the manual wasn't making sense to me and the key insight is that the value in the right only changes after a reboot!

Thanks a lot (to both of you). Too bad I paid for 3000Mhz sticks which are more expensive. I will contact the shop.

Maybe a motherboard upgrade can help... But I don't really want to deal with the shop anymore. I'll see... Sometimes the solution is to learn yourself. But they really recommended the motherboard for the picked parts.
