Hello.
Few days ago I bought a Asus ROG G750. However, it have only 4gb ram. Now I don't know what memory to buy. Please advice. I'm adding screenshots from CPU-Z.

It literally says in the "sticky" section.

You need 1.35 V memory at 1600 Mhz if you are keeping the old ram modules installed, 1.5 V memory is said to carry the risk of damaging your laptop and apparently higher speeds can work if original memory is replaced. You will need to check what speeds work as I haven't personally researched this.
Please refer to this thread for any other questions or comments, ( https://rog.asus.com/forum/showthread.php?33744-Upgraders-1-35V-memory-is-required! )

Edit: hmscott, thank you for correcting me. I do believe my post has been fixed.

You need 1.35 V memory at 1600 Mhz, 1.5 V memory is said to carry the risk of damaging your laptop and anything above 1600 Mhz is said to still run at 1600 Mhz regardless (the speed is always 1600 Mhz).

humannus, you have exactly what you need to do a google search, samsung m471b5173qh0-yk0, to find additional 4GB SODIMM's.

How many 4GB SODIMM's came with the laptop? The G750 series has 2 SODIMM sockets easily acessible on the bottom - you can add 2 x 4GB of the same SODIMM's.

You can also look for the matching 8GB SODIMM from the same family, those would be compatible without needing to remove existing memory, M471B1G73QH0-YK0 8GB

When I added an 8GB SODIMM to my 24GB, I found the exact same make/model on ebay - a Macbook Pro pull / used - inexpensive and compatible :)

If you want to install faster memory, you will need to remove all the existing memory, and replace it with the faster spec memory...


Dylanmk2humannus, it turns out that the Asus ROG G750 and G751 both recognize and run at the settings in the SPD. You can see the memory speed, and benchmarks show it as well :)

The popular G.Skill 1866mhz and 2133mhz 2 x 8GB and 4 x 8GB packs cost just a bit more than the stock memory and give a little additional benefit in performance.

Unfortunately, you need to remove *all* the original memory before putting in the faster memory, they aren't compatible. So that means you need to take the keyboard plate off the top to get at the top 2 SODIMM slots.
