Hello everyone.
I preordered a FW laptop 16 last month, and have bought the Kingston Fury Impact 32 GB (2 x 16 GB) 5600MT/s DDR5 CL40 for my setup.
I wanted to ask if anyone has already got their laptops and checked the compatibility with that memory kit, or if maybe the FW team has done something alike.
Also, I think it would be helpful if they listed memories tested by users that worked.
As a heads up, that kit appears to be an XMP profile for 5600MT/s. The reviews point to it defaulting to 4800MT/s for non XMP supporting machines. It’ll probably work, just at the lower speed as framework does not appear to be supporting the profiles this time around either.
The relevant footnote from the horses mouth:
- Kingston FURY Plug N Play memory will run in DDR5 systems up to the speed allowed by the manufacturer’s system BIOS. PnP cannot increase the system memory speed faster than is allowed by the manufacturer’s BIOS. Kingston FURY Plug N Play DDR5 products support XMP 3.0 specifications so overclocking can also be achieved by enabling the built-in XMP Profile. PnP is only featured on 4800MT/s and 5600MT/s speed modules.
the G.Skill equivalent is a bit more murky:
Tested Speed (XMP/EXPO) 5600 MT/s
Tested Latency (XMP/EXPO) 40-40-40-89
Tested Voltage (XMP/EXPO) 1.10V
SPD Speed (Default) 5600 MT/s
SPD Latency (Default) 40-40-40-89
SPD Voltage (Default) 1.10V
I’m confused now.
The Kingston datasheet I mentioned in the topic start does not mention XMP profiles.
KF556S40IBK2-64.pdf
Are there differences?
Kingston seems to market PnP as their own custom alternative to JEDEC or XMP/EXPO. They claim that PnP should be plug and play like JEDEC, however at faster speeds.
In practice it seems like PnP is only advertised at speeds that are also possible with JEDEC, so I suspect PnP is just Kingston’s marketing term for higher JEDEC speeds.
That indicates that if the BIOS limits the maximum speed of PnP/JEDEC ram (most older systems are capped at 4800 MT/s) then it also supports XMP so that if the BIOS does allow XMP then the user can enable XMP to override the BIOS’s speed limit.
To me that sounds the same. JEDEC at 5600 MT/s cl40 and in case the BIOS doesn’t allow that default speed but does allow XMP/EXPO it also supports XMP/EXPO at the same 5600 MT/s cl40.
I see now on the product page there are Plug and Play kits as well as XMP kits. We might just have to wait for early adopters to report back.
@ParticleCannon, that is what I expect at this point. to see what kits end up shaking out, Kingston ‘does’ sell stuff based on their website that are pure JEDEC 5600 like: this one but appear to have worse timings compared to the PNP kits.
@Bart, didn’t see the datasheet you mentioned until now, and the listing on Amazon appears to match that product number. I guess this will come down to whether the PNP works or not on the Framework system… I was just basing my statement off of the reviews of the kit at Amazon which seem to point towards lower than expected speeds on systems that do not support XMP, or some kind of issue with how intel chipsets are handling the handshake at the time of the reviews.
I suspect that is likely because only current gen CPUs officially support 5600 MT/s without XMP/EXPO, so on older systems the BIOS will automatically limit it to less (ex. 4800 MT/s) unless the user enables XMP/EXPO. I suspect most of those reviews were probably from users with systems like that.
I got a Kingston KF556S40IBK2-32 Kit lying on my desk and I’m just waiting to get the upgrade mainboard and will report back here.
I’m in batch 1.
I got this kit KF556S40IBK2-64 Kingston Technology Fury Impact 64GB (2x32GB) 5600MT/s DDR5 CL40 defaulting to 5600 MT/s without having any problem with XMP advertised on the package.
So far so good !
framework 13 DIY, with amd, 7840U, works with 2modules of the following brand / model:
crucial DDR5 5600 SO-Dimm, 1.1volt, cl46
Crucial CT48G56C46S5
just assembled the DIY AMD edition and fired up the bios/POST sequence only, it shows the 96GB total ram. probably usable 
dont have time for much more atm.
amazon/ASIN is: B0C79T2CP7
enjoy.
meanwhile: i have finished at least one round of memtest+ (memtest.org) with the full 96GB ram installed. it tested all fine, and has real high transfer speeds (59.6GB/s)
memtest86+ screen after the first successful pass: openSUSE Paste (image link valid for 3months)
real life usage of this system with linux: opensuse leap 15.5 KDE live iso image boots and runs just fine. so does some gparted iso distro (partitioning, tools etc.)
tried these three booting fine from a ventoy usb stick just fine (secureboot disabled in bios/uefi)
p.p.s: after several weeks I can report I dont have yet any problems of instability or anything at all, 2x 48GB ram (96GB total) works perfectly normal and just fine. linux system that is.
Did you know that you can add the ventoy key to the Bios and keep the secure boot loader ? I don’t know for opensuse but Fedora/Ubuntu publish with their own key signature that is recognised by modern bioses, so you can stay secured the whole process.
See the following page, and look at the gif. It’s really easy !
i guess I know… MOKenroll MOKutil and what not. didnt bother to go down the road for enrolling own keys and stuff. i dont really like secure boot and uefi and all actually ;p
were you able to run it at any higher speeds? my mainboard arrived as an upgrade to my 11th gen fw13, but I was waiting for a deal on RAM that can be overclocked a bit
No I did not tried to change anything since I’m not really interested on overclocking. The performances so far on my usages (and some gaming on NMS) are really good. Way better than my 3years old desktop workstation (3800X, 32Gb DDR4, 1060 GTX 6Go).
Received my 7840U motherboard today and successfully upgraded my 1165G7 board.
I can confirm that the G.Skill 64GB kit here works at the rated 5600 MT/s and 46-45-45-89 timing.
Anyone run it at 6400MT/s ?
