You can’t, the max is 5600 mhz as per AMD’s spec sheet.

So you’re saying that there’s no overclocking on memory speeds available in the current iteration of the Zen 4 mainboard?

44

Yeah. If you want higher speeds, you need soldered memory.

45

Thanks so much! i was going for a 2x16 kit from this product line. Im so glad to hear it works!

in order to keep upgradeable sodimms framework was stuck with the limit of the cpu from amd’s spec sheets

Has anyone tested this kit yet?

G.Skill Ripjaws 64GB Kit DDR5-5600 CL40 (F5-5600S4040A32GX2-RS)

Even if you have faster memory modules, the framework BIOS available to consumers doesn’t allow for timing tuning (e.g. no user-define CAS).

49

Someone on reddit said a few days ago that was working fine.

Can now personally confirm that the 64GB Kingston Fury Kit with 5600Mhz works out of the box with the correct transfer rate.

In addition to previous reports, I can also confirm this kit is working.

Although my kit appears to be running at 40-40-40-90 instead of 89 (which the Reddit screenshots from another user seems to confirm the same result.)

52

Would you please upload a screenshot showing the timings?

Batch 5 here, and looking to buy memory so I am ready for delivery in a couple of weeks :slight_smile:

Appreciate the input on this thread. However, I am hesitating between 2x16GB of Kingston or GSkill at CL40 vs 48GB of Crucial at CL46 (price here in Europe is about the same). Any views on the impact of the approx 2ns more of latency with the Crucial (16ns vs 14ns)?

To summarize:
Currently there are two 64GB DDR5-5600 CL40 kits available:

  1. G.Skill Ripjaws 64GB Kit DDR5-5600 CL40 (F5-5600S4040A32GX2-RS)
    with JEDEC timings: 40-40-40-90-130 running at 2791.1 MHz
    (40-40-40-89 probably with XMP)

  2. Kingston Technology Fury Impact 64GB (2x32GB) 5600MT/s DDR5 CL40 Laptop Memory Kit
    with JEDEC timings: 40-40-40-80-135 running at 2788.8 MHz

Question for the memory experts: “Which one of these would you prefer and for which reason?”

G.Skill, it is much cheaper.

57

Anyone with the Ryzen 5 7640U APU and a pair of Kingston Fury memories clocked at 5600MHz and running in Dual-Channel, or a pair of similarly-specced G.SKILL ones running in the same configuration?

I need to choose between Crucial and those other two; and after browsing a half of the Internet, and watching a dozen of YouTube videos on the topic, I concluded the deciding factor for me is going to be a graphics score in 3DMark Time Spy, regardless of how unwise this may be of me.

So, I’d really appreciate if anyone with the aforementioned setup(s) could run that benchmark for me. As an added bonus, if we get benchmark scores for both G.SKILL and Kingston, this would also help 7640U owners torn between these two to buy the right memories for themselves.

Edit: The benchmark scores of Crucial for those interested: Reddit - Dive into anything

Edit#2: Anybody willing to run the benchmark is also invited to post their benchmark results, regardless of their setup.

In germany there’s no big difference between those two concerning the price, so my focus was on the timings and the clock speed. Or would you dare to say, that only the first three timing values are of importance?

EDIT: I tried to do some own research on that matter and according to this explanation, the G.Skill timings are performance-optimized (tRC = tRAS + tRP) while Kingston priorizes stability (tRC = tRAS + tRP + 15). Furthermore, a higher clock speed is preferable for gaming. Is my conclusion correct?

59

I have the DIY version of the framework 13 AMD but I want to buy 2 RAM sticks 16gb what RAM should I buy for this?

And another question what is the fastest 2 TB NVME storage that I also could buy for the laptop?

AMD Ryzen™ 7 7840U

60

I went with Crucial for RAM and Storage…I don’t need the fastest storage so I went with a P3 model. You’ve got plenty of options…I know FW deals with Crucial & Samsung for their DIY…so to me that sounds like its proven to work with the rest of hardware. SK Hynix is another good brand. I’m still waiting for my AMD board to arrive so I can’t speak concretely about performance just yet. In the past however, I haven’t had any issues with those brands.

61

Also make sure you get DDR5-5600 non XMP, which is the maximum rated speed the laptop can handle.
