There are now 3 reports of users not being able to boot with 5200 mhz ram. I think the pattern so far is RAM below 5600 mhz appears not to work.
Edit: We have 1 report of 4800 mhz ram working so we’ll have to see about 5200 mhz ram.

Well they’ve finally admitted it’s delayed, but it still says it’s still saying the updated delivery day is today LOL

Would it be ok with you if I copied this poll to the Batch 2 Guild thread?
@TheTRUEAsian That helps. Yeah it does seem that way. logically it makes no sense why a lower frequency but still jedec kit wouldn’t work. Perhaps this is something a Bios update may fix. But for now I will get 5600 to try
Indeed although I definitely want to get a larger sample size before coming to any solid conclusions. Once we have enough, maybe we could get someone from Framework to chime in? From their DRAM compatibility tests, all of the tested kits were 5600 mhz although they did test 4800 mhz ECC kits as well. However, I assume the ECC kits were tested more so for ECC functionality rather than for speeds.
I am curious about 4800, cause I’ve got that right now, so we’ll see when mine arrives I suppose. I’ve got the Crucial CT16G48C40S5.

I do notice that this is a dual rank kit, and most of the validated list are single rank with the exception of one of the ECC ones, so I wonder if that might be causing issues
Although, assuming the Amazon listing for the Crucial 5600 mhz kit is correct, it is a dual rank kit that others have confirmed is working. I can’t seem to find the product sheet for it so if someone could link it here, that would be great.

I had the same issue with 23.10, 22.04 seems to be working just fine though for me at least (most notably after installing the oem kernel and what not).

I need Fedex to hurry up, I’ve been sitting here anxious on if my RAM is gonna be compatible or not for so long LOL it’s just been sitting in a facility an hour away for 8 hours
Launched! Windows 11 in this case but my SSD was already pre installed with a Windows 11/Linux Mint combo. Will have to check how Mint holds up.
Mainly because I took my sweet time unboxing and reading the manual, it took me 20 minutes to DIY it and boot it up.
I’m curious to how it holds up in general. I’ll be running several benchmarks
Hardware list:
- Ryzen 5 7640u
- SK Hynix P31 Gold 2 TB
- Crucial 2x 32 GB 5600 MHz (CT2K32G56C46S5)
FedEx once again visited the wrong house so right before they left I noticed and intercepted them before they were gone.

Out of curiosity, why Debian? I love Debian but it moves a bit to slow for my liking
I work on KDE packaging for Debian. Also yes Debian stable moves slowly but if you’re ready to cope with rare breakages, testing is close to being a rolling distro.

My FW is now operational with the kit from Kingston (KF556S40IBK2-64)! Thanks again to @0xFF and others for reporting working modules early on!
There are apparently some instances where the 5200s are working (not sure which, yet), but I would avoid 5200s if you are still shopping around (or can still return yours). Not worth the hassle. Besides, who doesn’t like more speed?!
Best of luck to all that are still waiting!
