Thanks @Andreas_Braun
TEAMGROUP T-Create CTCCD532G5600HC46A-S01 Classic DDR5 SODIMM 32 GB 5600 MHz (PC5-44800) CL46
working in single channel mode.
x2 (not a kit) not booting.
were good price 100€ at german amazon (per 32G)
Can report two different kits working:
Kingston KF548S38IBK2-64
64GB (2x32GB) DDR5 4800MT/s CL38 FURY Impact Black PnP
Lenovo OEM Samsung M425R2GA3PB0-CWMOD
32GB (2x16GB) DDR5 5600MT/s
As I was enjoying the Holiday season 2024, I did not realize that my Framework 13 AMD 7840U (mainboard) supports RAM higher than 64 GB.
The original pre-orders offered 64 GB RAM (Framework shipped with the hynix H5CG4BAGB0,
I purchased and installed Crucial CT2K48G56C46S5. It was recognized. I tested it with passmark and have not need seen any issues.
This further extends my original Framework 13 11th Gen Intel as I upgraded to the AMD 7840U. Now the RAM upgrade will make this my main development laptop.

Hi.
I could confirm working kit 96GB on FW 13 AMD Ryzen 7 7840U.
I have this:
G.SKILL SO-DIMM 96GB KIT DDR5 5600MT/s CL46 Ripjaws
PN: F5-5600S4645A48GX2-RS

Note: 128Gb (CT2K64G56C46S5) also works fine with 7840U (however hibernation works on one of two FW13 with 3.07 BIOS)
What OS are running? Linux or windows?
I have not moved my BIOS to 3.07 yet. Everything is working ok for my current needs.
Thanks for the details on this crucial memory configuration.

Both (Win11 / Ubuntu). With my old (11 gen upgraded version, Batch1 for Motherboard) I have no issues. My wife’s (Win 11) recent one (7840U out of the box), there issues with hibernation and sometimes it’s just not started (black screen… however after power off and power on - all working).
And there no way to rollback from BIOS 3.07, so I would suggest to not move if you really need it. 3.05 is much more stable.
Thank you for that detail and I will stay at the BIOS version.
Also nice to meet you as I was Batch 6 on the 11th gen ( i7-1185G7), batch 2 for the 12 gen (i7-1280p ), and batch 3 for the AMD 7840U.
I upgrade the framework 11th gen to the AMD cpu using the coolmaster case to keep the 11 gen main board as a “desktop”.
Take care and have a great Friday.
Has anyone read the “Specs page” ?
It said the CPU can support 256 GB. The detail @Dmitry_Elsakov shared confirms 128 GB.
If 256 GB can be supported that would make this mainboard model quite useful.

I believe you need 128Gb SO-DIMM memory sticks… Here example of DIMM (Desktop) with 2x128Gb and even 256Gb in one stick… But price for similar SO-DIMM (I saw they do exists somewhere in news) would be like 4-5 new Framework laptops 
As of now 2x64Gb is maximum you could get for more-or-less “good” price.
Another option is 4x64GB, but we have only 2 slots.

Wow, that is pricey. I would probably get a Framework Desktop for that price.
Those are REGISTERED DIMMs, for servers.
128GB Unbuffered DDR5 DIMMs will likely never exist.
The maximum capacity for Unbuffered DDR4 DIMM was 32GB, and the maximum capacity for Unbuffered DDR5 DIMM is likely to be 64GB.

Year ago same posts were for 32Gb+ and now we have 48Gb and 64Gb in one stick for DDR5.
With extension of NPUs (and hype of ML/AI), I believe there would be some further extensions.
At least I saw somewhere that Micron continue to extend size for DDR5 and CAMM modules (not a SO-DIMM though) of 128Gb have already been announced recently…
So, who knows 
P.S.: If you look at the very beginning of this post, discussions were started for 2x16Gb and if it would work on FW13… And now we have 2x64Gb..

Totally Agree.
Last night I received the 128 GB via 2 64 GB I ordered. My previous pair of memory totally 96 GB are retired as backup parts.
It is amazing to have a 13" laptop with 128 GB RAM – I upgraded my NvME stick to 8 TB over Christmas 2024 due to a couple price drops. It is amazing how this is a laptop and not a desktop.
