Hi.
I recently bought a used complete system and was just looking through it when i noticed it has different sticks of ram.

Asus Tuf X570-Pro Wifi
Ryzen 5600G
32gb ram running at 2400mhz in cpu-z

I have
1 stick of Crucial ct16g4dfra32a.c16fn 3200mhz 16gb but i have noticed this is not running at XMP profile in cpu-z
2 sticks of Teamgroup-ud4-3000 2x8gb, these are running at XMP 2.0 in cpu-z

So, is it worth it buying a 32gb 3000mhz set for me or is the ram set up wrong in the bios etc.?

What a weird combination of parts.

I'd sack off the TeamGroup sticks and just buy 1 more stick of the 16GB 3200mhz crucial sticks. Then you've got 32GB, running at 3200mhz in dual channel - and you can sell the TeamGroup sticks to get a bit of that cost back.
 
Another option would be removing the Crucial stick, and just running the two TeamGroup sticks in the right slots for dual channel. Of course that only works if 16GB is enough for your usage (it might be). You could try it first and see, seeing as it's free to try.

Performance-wise, getting dual channel working is what's important here. That's significant. A few more mhz is secondary.

true, but i would prefer 32gb if possible

I think what you're reading as XMP is just telling you that the sticks have XMP (Spd Ext likely means SPD extension), not that they're XMP enabled. From what I can gather, they're both just running standard JEDEC timings at 2400.

Your Crucial stick is very rare in a gaming system, in that it doesn't require, nor specify XMP. If you put it in a PC that supports 3200 "out of the box", then it will boot at 3200, with only a standard voltage of 1.2v required (unlike gaming sticks, which are usually rated for 1.35v).

The Teamgroup modules appear to be gaming memory and to run at their rated speed, the XMP profile for this entry (3000), specifies 1.35v.

The highest speed the Teamgroup modules support with XMP off is 2400, which is likely why the board chose this, since the Crucial stick also had this entry available.

Should be able to get it to run dual channel with that setup if you put both 8gb in one channel and the 16gb in the other.

Never thought of that lol, it would be only 24gb but it may be enough.

Why would it be 24GB? You'd have 2x8 in one channel (16GB) and 1x16 in one channel (16GB), making a total of 32GB in dual channel.

Thanks for the explanation.
Sorry but i am trying to understand how ram actually works lol.
I presumed that when Dg834man said to run them in separate channels, he meant in the slots on the mobo ie. remove 1 stick of 8gb ram and just run 2 sticks, 1 x 16gb and 1 x 8gb.

If you inherited this system, what you you do ?

edit.
Just had a look at the mobo.
slot B1 (nearest cpu) is empty
B2 has 8gb
A1 has 16gb
A2 has 8gb

The memory controller is divided into two channels, A and B.

The channels can be either 1 slot or 2 slot each (depends on the board, but X570 is pretty much always 2 slot per channel, for a total of 4).

If you have an equal capacity of memory in each channel, then it will be run in dual channel mode across that entire capacity.

In other words: we don't care how many sticks per channel, just that the overall capacity, per channel, is equal.

2x8GB and 1x16.

The manual might tell you which slots to use, but I think B1 and B2 are channel B and A1 and A2 are channel A.

What I would do, is just move the 8GB stick in A2 to B1, unless you have ram clearance issues due to the cooler, in which case:
B1: Empty.
B2: 16GB.
A1: 8GB.
A2: 8GB.

Right now, I believe you have 24GB in one channel and 8GB in the other channel, which gives 16GB of dual channel and 16GB of single channel.

I tried what you suggested, to my eyes nothing has changed.

Is it ok as it is for now or would you recommend to buy either another matching 16gb stick or a new 32gb set?

I don't think it would look any different, because you were already in dual channel mode, but it should be across the whole capacity now instead of just half of it.

If it was me, I'd just leave it be now. If you're gaming, then achieving a higher frequency would be nice (e.g. 2933), but it depends how much you want to mess around with it.

Thanks for all your advice

If both different sets run at 3200mhz and 3000mhz respectively then it's a compatibility issue.

Since the system was configured by someone else, they may have just stuck the RAM in and left it.

One stick is XMP and one stick is not, so I think 2400 was just the highest JEDEC speed that the BIOS could configure (profile #9 with the TEAMGROUP sticks).

I suspect manual config would get the OP at least 2666.

I agree.

At least if tested at there rated speeds will confirm they all working correctly then the tinkering starts .
