Question Can I use faster DDR5 on a mobo that supports slower DDR5 (backwards compatibility/downclocking?)

[Turbonium]

Motherboard in question:

Pro Q670M-C-CSM｜Motherboards｜ASUS Global

The ASUS Corporate Stable Model (CSM) program is designed to provide stable motherboards to any scale of businesses with up to 36-month supply, EOL notice & ECN control, and IT management software â ASUS Control Center Express.

www.asus.com

Memory in question:
DDR5 5600 1.35V
or
DDR5 5600 1.25V
or
DDR5 5200 1.10V

I take it the important aspect here is the voltage the motherboard supports. Unfortunately, I can't seem to find what voltage those RAM slots are rated for.

EDIT: found this link.

So it only supports RAM sticks that take 1.10 V?

 

[WelshBloke]

No. The sticks are physically different. DDR4 wont fit in a DDR5 slot and vice versa.

It's a DDR5 4800 mobo.

The memory should run 4400/4800 by default if that's all the board can handle. That page is listing the voltage THOSE memory mudules require. I'm sure you could turn it higher.
Generally memory modules are more stable when run below their rating.

Do you already have the board? Seems kind of dated to invest in.

I'm not sure I understand. So you're saying I can run memory modules with the mobo, even if the modules require higher voltage than the mobo can deliver? Sorry, I'm not very well-versed with memory tech. And I always thought higher voltage = better for stability, assuming nothing breaks. Or did you mean lower speed than what they're rated at, not voltage?

As for the mobo being old:

Question - solid mobos that don't try to look all "cool" (not OCing)

Are there any mobo manufacturers that make a solid product (stability above all else, followed closely by performance) without also trying to make their mobos look "cool"? Keep in mind I am not planning on OCing. Seems like almost all mobos nowadays are all "fancy". I'm a bit of a purist, so I...

The QVL shows a few DIMMs with 1.2V so the mobo can handle that voltage. Anything higher may or may not work.

From your link to the motherboard, go to Support -> CPU/Memory Support -> Memory

Sorry read the question as faster ddr5 on a ddr4 motherboard!

All Teamgroup modules, apparently.

Yeah, I didn't realize those tables are the QVR. I thought it would be something more official.

By the way, how risky is it to pry off G.Skill Trident Z5 heatspreaders (using only something like say a blowdryer on very low heat setting, and some isopropyl alcohol to hopefully weaken the adhesive)?

I didn't say old. I said dated. As in lacking features that I would want for that price, including the ability to run decent DDR5 speeds. I'd get a 7 series chipset.

Your requirements are silly if the case doesn't have a window. The board is going to look the same whether it's plain, or not. If it has lights, turn them off.

Why would you want to pry the heatspeaders off? Your case isn't going to have a window, you can't see them, and you will void the lifetime warranty.
You'll also kill resale value.

I'm just weird/highly particular.

Also: I'm thinking of modding the side of my case so that it has a window, fwiw.

Modding the case with a window, but don't want a good looking board, or heatsinks on the memory....

I'm out.

At some point early in DDR5's popularity, aaawave.com had Samsung OEM DDR5 modules without heatspreaders.

I don't want to start a new thread, so I'll just ask this here:

Is V-color a reliable memory manufacturer (I never heard about them until very recently)? The sticks in question use Hynix chips.

Never heard of them.

I've been doing research, and basically all reviews of their memory (various models) show that it's good stuff, so I might try it.
