Is the memory configured correctly?

[nelsoneci]

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.

Seems to be set for full XMP frequency of 3000MHz. Do you have windows installed ? If you do check real values with CPU-Z for instance.

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:

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 🙂

Thanks!

Definitively running at 2133MHz. What does SPD tab say ?

Ops. Here's the tab.

 

[CountMike]

So everything is true, XMP is 3000MHz but it's using JEDEC profile. See if you can set Memory multiplier to 30 manually. Memory voltage to 1.35v too.

I'm confused here to be honest.

Cpu-z shows dual channel.

Do you have 1 stick,or,2,fitted ?

 

[madmatt30]

Try profile 2 on xmp memory settings

If this does,nothing the set xmp to disabled.
This will open up the 2 settings below & you should be able to select 2933mhz manually.

Hi madmatt30! I have 2 sticks! 16GB each. Slots 1 and 3.

 

[madmatt30]

^ I thought so.
Try what I suggested , I think you may only get 2666mhz max with double rank 16gb sticks thpugh on that board.

 

[CountMike]

Have you tried in 2 and 4 ?

 

[nelsoneci]

Have you tried in 2 and 4 ?

Oh, I was counting from 0, sorry! Programmer's bug... It's actually 2 and 4.

 

[madmatt30]

^ not the issue mike.
Slots 1 & 3 are right.

Theres just some,confusion on bios settings.

Looking at the manual the info just seems generic.

Xmp profile 1 though is plainly setting a base 2133 ddr4 speed.

 

[CountMike]

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.

[madmatt30]

Looking videos (all gigabyte b350 boardsrun the same bios)
Xml profile - + or - key to set to disabled.

Go down to system memory multiplier

+ or - to change default memory multiplier

I would try 2666 first

Save & exit.

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...

 

[madmatt30]

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.
