memory configuration validated: 

• 8 GB DDR4 at 2666 MHz (1 x 8 GB)
• 16 GB DDR4 at 2666 MHz (2 x 8 GB)
• 32 GB DDR4 at 2666 MHz (2 x 16 GB)
• 64 GB DDR4 at 2666 MHz (4 x 16 GB)

crucial claims their 3200 MHz ram is 100% compatible w g5. You can call them if 3200 spec is guaranteed or not (if not do you get your $ back).  https://www.crucial.com/memory/ddr4/bl2k8g36c16u4r/ct17093789

Purchased this and works out of box/no issues on my end (G5 Gaming 5090).

Awesome thank you for everyone’s help. Definitely going to go with that.

cheers!

@giordan0 Finally purchased and it is compatible. I went with the 3200mhz but it still is only running at 2666mhz. Are you having the same issue?

Yes it will only run at 2666Mhz (mines is a locked processor and cannot be OC).

@Adamal85 - The RAM will support speeds up to 3200, but if your system only runs at 2666 then it will run at that speed. Sort of like having a Ferrari capable of 200mph, but you're in traffic doing 55.....it *can* run faster, but it's limited by other factors.

I'm buying the same set of RAM soon - glad to hear it's running at 2666, some users have reported their other brands of RAM only running at 2133.

Maybe @Anonymous would be kind enough to update the bios with the needed settings to run gaming memory on a GAMING laptop. 

Same issue. They fail to clearly state it only runs at 3200 on Intel's XMP profiles.
