Compatible RAM for Laptop

[Yone]

I would like to add more memory to my gaming laptop (Asus ROG Zephyrus G16, model: GU603VV-G16.I74060).

 

I bought a 16 GB stick of Corsair Vengeance SO-DIMM DDR4 RAM (3200MHz, PC4-25600, CL-22) and I wanted to double check if it was compatible. As far as I can tell, it should be. The ram already in the laptop is 16GB Micron DDR4 3200 MHz (ATF2G64AZ-3G2F1), which seems to be CL-22.

 

Is there anything I'm missing? I'm not really clear on the difference between single and dual channel, but if the type, speed, and latency are the same, it should be fine right?

 

(I can't get the Crucial System Scanner to work, and I downloaded CPU-Z, but it isn't showing the latency for the currently installed RAM).

Usually, yes. But there might be differences you don't find on the spec sheet that might cause issues in rare cases.

 

You shouldn't need a system scanner, you can usually just visit Crucial's website to see what they recommend: https://www.crucial.com/compatible-upgrade-for/asus/rog-zephyrus-g16-gu603vv-n3058x

 

Dual channel = double the memory bandwidth. Simply put, more performance by going with two, rather than one memory stick.

I also wasn't sure which model on their site was the right one, but that seems to be it, thanks.

 

Maybe a dumb question, but since they only recommend Crucial RAM, how can I tell what will work from other brands, especially if you can't always tell from the spec sheets?

The best you can normally do is find RAM that has the same specs as what they're offering. If you know what ICs are used by the existing RAM, you can take a more educated guess, but that is beyond me.

 

But as I said, the chance of issues is very low. Especially for RAM that is running within JEDEC specs, as 3200 CL22 does.

That's good to know.

 

I also asked tech support from the place where I bought the laptop and the place where I bought the RAM. One said it is fine, and one said there could be compatibility issues if it's not the exact same type as what's already in the laptop. But the RAM already in there is soldered in, and I can't find that exact type to buy.

 

If the chance of any issues is small, I think I'll do it. How would I know if there's a problem? The new RAM module not being recognized? Performance issues?

If there's a problem, you're typically faced with a system that refuses to boot, so hard to miss If it boots with both sticks, you're good.

 

That's mostly an issue on desktop with overclocked RAM (XMP/EXPO), where in most cases it will then run when that is disabled and you go back to JEDEC speeds. Since you're on a laptop that's limited to JEDEC anyway, much less chance of issues.
