Hey, I’m curious what memory the current Framework board. From what I can determine the CPU supports up to DDR4-3200. From my own digging, it seems the Framework prebuilts use 3200 boards at CAS 22 at 1.2v. Is there any more information on what the stock modules are?
Does the board support higher voltage chips and/or XMP?
To add to your questions, when choosing my own RAM, will the SO-DIMM sockets provide enough clearance to support cards with chips on both sides, or do I need to select sticks with chips all on one side?
Thanks for posting your results. I did suspect that this would be the case.
DDR4 RAM has tables to tell the motherboard how to automatically clock/time the memory. XMP is an extension of that table that specifies configurations outside of what JEDEC (the developer of DDR4) recognizes. You can think of XMP profiles as the memory manufactures’ tested-and-suggested overclocking profiles.
Anything not found in this table and running at 1.2 volts can’t be specified by the normal table as it’s not technically part of the standard. If your DDR4 so-dimm’s advertised timings is not in the table, or it’s not at 1.2 volts, it’s almost certainly using XMP profiles to get there. So be careful to avoid 1.35v modules for this laptop.
We’ve had a report of Kingston HyperX HX429S17IBK2/32 memory not booting on the Framework Laptop. We’re digging into what is causing this, since it should fall back to a standard JEDEC timing rather than not booting. In the meantime though, we recommend using non-XMP memory that runs natively at 3200.
