Question x570 Gigabyte Aorus Xtreme only supports RAM up to 3200 MHz?

[MoreMoneyThanSense]

Am I misunderstanding something?

According to their QVL thing http://download.gigabyte.us/FileList/Memory/mb_memory_x570-aorus-xtreme_picasso.pdf it only supports RAM up to 3200 MHz? So it would not work properly if I were to buy 3600 MHz RAM for this motherboard?

You can for sure use 3600mhz ram. It should boot up at 2133 or 2666 and then if you turn XMP or docp on the ram will run at 3600.

The worst case is the 3600mhz will run at 3200.

Whoops I was looking at the wrong PDF, it's this one I think http://download.gigabyte.us/FileList/Memory/mb_memory_x570-aorus-xtreme_matisse.pdf

It looks like most of these only go up to 16GB? Does this mean this hasn't been tested / verified with 32 or 64 GB?

I was interested in this RAM (G.SKILL Trident Z Neo, 4 x 16 GB, 16-16-16-36 timings, F4-3600C16Q-64GTZN): https://www.newegg.com/g-skill-64gb-288-pin-ddr4-sdram/p/N82E16820232864

And was looking at the Gigabyte x570 Aorus Xtreme which has this QVL sheet for memory: http://download.gigabyte.us/FileList/Memory/mb_memory_x570-aorus-xtreme_matisse.pdf

Am I misunderstanding, or does it look like nothing above 16 GB was tested for this motherboard?

If I were to get a 3900X or a 3950X when it comes out, would it be difficult to actually use all this RAM at this latency / frequency on this motherboard and have it be stable, let alone try to overclock it?

They may have not tested with anything over 16gb, however, the 4x16 kit should work.

You should have no struggle getting the ram to run at those speeds and timings.

1. How do you know 4x16 should work?
2. How do you know there wouldn't be a struggle to run at those speeds/timings?

(Not questioning you but rather just trying to learn how to fish here / what to look for / how to be able to tell)

1) Gigabytes webpages says "4 x DDR4 DIMM sockets supporting up to 128 GB (32 GB single DIMM capacity) of system memory"

2) Ryzen 3000 has an improved memory controller. AMD recommends 3600mhz C16, so AMD must be confident it can hit that.

1. I do know that it supports up to 128 GB via four DDR4 DIMM sockets, but I don't understand how this ensures that any-four-such DDR4 DIMMS will work stably -- for instance then what is the purpose of the QVP sheet in terms of how we're meant to use or interpret it?

2. Indeed this is precisely why I was targeting 3600 MHz C16 to begin with, but my concern was whether or not it is stable in any amount the board accepts, since I often read about people who are unable to get their RAM stable when they start crossing e.g. 32 GB or 64 GB, and have to weaken the frequency or latency to get it to work.

Your overthinking this.

The QVL sheet just shows what kits are tested to work with the board. Just because ram isnt on the qvl, doesnt mean it won't work properly.

My kit isnt on the qvl of my board and yet it runs perfectly even with a mild overclock to 3333mhz.

That being said, there is not guarantee that ram will work at rated speed and timings either. Theres no way to 100% ensure a kit will work. But i would suggest the majority of 3600mhz c16 kits will work with your motherboard.

Btw ryzen doesnt like 4 stick of ram, but it should still work, just maybe with increased voltage.

What do you need 64 or 32gb ram for anyhow?
