I want to upgrade ROG Strix G18 (2023) RAM to 5600mhz in BIOS

I want Asus officials to support this issue. I want to upgrade ROG Strix G18 (2023) RAM to 5600 mhz. Please do a bios update for it. Other brands allow up to 6000 MHz.

Don't mind me, I'm just guessing.  Although the picture you posted does not necessarily imply that both 128GB and 5600MHz can work together. MSI's GT73 has 128GB RAM but only 3600MHz speed, not even 4800MHz. Now that could be some cost cutting, but it could be that the CPU can not handle both that much RAM and speed together.

As I mentioned, all Razer's new laptops have 32GB and 5600MHz RAMS, but when they released their 13980HX model later, they gave it a 64GB RAM, but only with 5200MHz, maybe because that's what CPU is capable of. Again, I'm only theorizing.

Dear @Kogashjne 

as the user Flo shared the intel documentation with us ( on page 3 of this thread ) it says that our 13980HX is in maximum support for single sided RAM for 5600MT/s and double sided in 5200MT/s. You can find the information on page 96 of this document ( marked here next in the screenshot ). Within this it could also explain the answer of @Ahmed92 where the 128GB is only running in 3600MT/s if the MSI GT73 is supporting 4 RAM Slots. As I don't know the correct build of the MSI, I just guess they're using 4 RAM Slots while I'm not seeing any 64GB ( or 128GB kits ) on the market yet and if they're using 2 dual RAM slots, it reduces the speed ( as you can see on the right sight of the screenshot ).Screenshot 2023-05-24 032143.png

In summary that means to us, the 16GB kit ( 2x 8GB ) and 32GB kits ( with 2x 16GB modules ) build up single sided may run at 5600MT/s while the 64GB ( 2x 32GB ) kits are build up double sided only support 5200MT/s 👍

Also CPU-Z, Armoury Crate, HWInfo and the task manager in Windows recognizing the RAM at it's supported speed correctly since BIOS version 312.

What I know is that Kingston Fury 32X2GB is single sided, but still runs at 5200MHz. Also, the guy you are replying to didn't even get 5200MHz, let alone 5600MHz.

KF556S40IBK2-64 is double sided 64GB kit 5600MT/s with 2x 32GB RAM modules and will support 5200MT/s by Intel and the newer 312 BIOS of the Scar 18 like you can see in my screens.

The smaller kits with 16GB or 32GB are single sided, that's true, but the 64gb kit is sadly double sided.

please read my latest post below first, I have taken a picture, after updating, my device still only receives 4800mhz, not 5600mhz

Yeah, I've seen this, but keep in mind that this thread is about the SCAR 18 and not the Scar 16... Maybe it could came up with the next BIOS version for your model ?! It's still possible that the Scar 18 users are some kind of test users for this feature. 

I have the SCAR 16 and got the memory speed boost. He didn't get it, sadly, even though we have the same laptop (except for a possible GPU difference. I have the 4090 btw).

I realy don't know the reason for that, but it sounds to me that you're using different types of RAM. While your system is initiating correctly, the trimming of the modules for Kogashjne should gone wrong. I realy don't know what happend there, but you can try to reflash the BIOS via EZ Flash in BIOS, try to hardreset your laptop or change the modules to the original once for testing.

In my case the BIOS flash duration was longer then all the updates before. After updating you don't have to do anything like restarting or hit the power button or something like that. It will automatically restart after flashing and training your RAM where your keyboard only flashes up and it seemed like it's doing nothing. Don't interrupt this scene ! You have to wait some seconds till the system resets itself and after all boots up into normal system usage. 

After all this procedure I get the right RAM speed in my system.

So there could be some reasons why he's not getting the right timings.

My BIOS is downloaded and processed through the MyAsus application downloaded through the Microsoft Store, not through the traditional way of Up from the Bios interface

Hi, you can try to force a new ram training, maybe it will help:

Enter your bios and press F9 to load optimized default settings, then save and exit.

Power off your laptop.

Unplug battery

Remove ram sticks

Wait 5 minutes

Put ram sticks back in, then plug your battery, then power on your laptop

From there your laptop will perform a ram training for about 3 minutes and after that Windows will start.

Check your ram speed.

Hope it help, finger crossed.

(This method from a user who was not able to boot his laptop with new ram sticks, and that procedure solved the issue).
