Is it okay to mix 48GB DRAM with 32GB DRAM?

[Anthony_Mak]

I have a single 48GB DRAM module currently installed: is it okay to add a single 32GB DRAM module or is matching different size modules a bad idea?

It’s for a Framework 13, Intel Core 7 Ultra 155H, Ubuntu 24.04.1 LTS.

Welcome to the forums!

This isn’t the first time it’s been discussed here, but the short answer is that due to Intel Flex Memory, you’ll still get the benefits of dual-channel memory as long as both modules are able to clock down to a matching speed (that’s compatible with the Framework), which most likely is the case.

You may want to search for previous discussions but here’s a couple:

Can I use different RAM sticks?

Can I install 2 RAM sticks of different types, like 16+32 or even totally different manufacturers?

Can I Use RAM with Two Different Capacity In The Same Laptop

Hi, I originally imagined that 8GB of ram should be enough for my daily task. However, when I opened my system monitor during my normal task, I realized that I am using 75% of my ram and 50% of my swap. I am not sure if it is bad or not, please let me know… If that means I am not having enough ram, I would like to buy more. However, to be future-proof, I think I will buy a 16GB stick this time. I was wondering if I can put 16GB stick and 8GB stick in the same computer at the same time. They ar…

Mixing RAM is never recommended. Your laptop is only going to run as fast as the slowest RAM. Not sure if you’ll get full DDR with a mixed setup. Some BIOS’ for motherboards will run DDR with mixed RAM and some won’t.

As a general rule though, you want to run Matched RAM. Bought at the same time (so they come for the same lot, hopefully) and the same size.

Also, I believe the max you can run in the Framework is 64 gb. Someone correct me if I’m wrong.

You can actually buy the Framework 13 (Ultra Series) with 96gb of RAM from Framework.

Thank you. Wasn’t sure how much they could take.

Thanks for the speedy and informative reply!

I had tried searching but the criteria I used was “different DRAM”. If I tried “different RAM”, I would’ve found those hits. Oh, well, live and learn.
