Just adding to the above answer, since the i7-1165G7 is a mobile CPU it’s safe to assume that Framework will only use Mobile CPUs and after a quick check, none of the 11th Gen Processors support ECC memory since it’s more or less designed for Desktop use cases. Unless Framework moves to support the other categories, having ECC is unlikely as Intel probably won’t ship it on their mobile CPUs.
Maybe if/when they make AMD laptops. Supposedly the memory subsystem of Ryzen technically all supports ECC. Even if they don’t publicly talk about it on the APU’s. Would be cool to have a laptop with ECC memory; however ECC DIMMs do technically use more power since they are self error correcting.

Yep! The AMD CPUs that would be use will defaultly support ECC! Frame.Work would just have to make sure their motherboard does. 
Yep, it is a no-brainer for the AMD version. The support is already there. It has to be enabled, perhaps with minor hardware adjustments.
The advantages are there even for regular people and adding support for this only makes the laptop so much more capable and expands the customer base. It does not take away non-ECC support, so when it is already supported by the AMD platform, any argument against it is weird and non-sensical.
Framework has the potential to push the industry to the better. It would only have advantages, minimizing data corruption, crashed and what would otherwise be unecessary troubleshooting where a solution is impossible because bit flips happens at random and cannot be prevented in software.
Ignoring ECC for an AMD-version is like putting functional rear doors on a station wagon, with hinges and door handles, but then spot weld a small spot between the door and chassis so the door cannot be opened and the car is limited to being a 2-door station wagon.

Linus should really step up on one of these efforts promoting ECC in Ryzen laptops. Either Thinkpad and/or frame.work… He has plenty of influence but these untouchables are so damn hard to contact - it would be an easy thing that he would want to do (promoting an ECC-compat platform that he’d definitely buy & use)…

The new Framework AMD laptop has two DDR5 SO-DIMM sockets, not LPDDR5.
So I am assuming ECC could be supported if Framework wanted to support it.
But since the company doesn’t mention ECC support anywhere, and is also not selling any configurations with ECC memory in the store, it’s best to assume that they didn’t want to support it and not to buy the new AMD laptop if you depend on ECC support.

Being hit again by faulty (and soldered-on…) memory in my current laptop, and royally pissed off at the loss of time and, possibly, data, I would be really, really happy to see a framework laptop with ECC support.
Really.

@John removing ECC support sounds really stupid of AMD. That is the main reason why I buy their HW.
In any case - Intel or AMD, ECC support is important to me.

@John I am not sure if you’ve seen in the other thread that AMD sneakily changed the product page for their CPUs between May and October:
It’s now stating: “ECC Support No”
The discussion is pretty much settled that AMD decided to not support ECC on the non-pro CPU models that Framework is using. ECC will not work on this year’s Framework laptops with AMD CPU.

That really sucks, product segmentation now that the market isn’t so bullish.

It really does. Unfortunately AMD is not alone with that BS.
But I would like to stay pragmantic and urge frame.work to offer new Laptop 13/16 configurations with AMD Pro CPU and ECC RAM bundled or preinstalled from the factory. I would say the ball is in frame.work’s court now. If they are not offering a variant with ECC support that is their choice.

Does anyone know if (lp)camm2 supports ECC ram?
I mean I would say that’s a distraction. I don’t want to wait for camm2 to maybe get ECC in a few years. I want ECC with the current available technology now. Frame.work could offer that with SO-DIMMs today.
But to answer your question:
yes, camm2 supports ECC RAM.
configurations can be:
- DDR x64 (x32, 2 subchannels) = Single Channel CAMM2
- DDR x72 ECC (x36, 2 subchannels) = Single Channel CAMM2
- DDR x128(x32, 4 subchannels) = Dual Channel CAMM2
- DDR x144 ECC (x36, 4 subchannels) = Dual Channel CAMM2
- LPDDR x128 (x16, 8 subchannels)
“A channel is 64-bit data interface with varying number of subchannels.
With ECC support, the channel becomes 72-bits wide”

So no lpddr and ecc, that kinda sucks. Especially since camm and lpcamm are apparently not intercangable.

why do you care about lpcamm2 over camm2?
Cause lpddr is a lot better than regular ddr and is the major reason I am excited about camm

It’s probably a tradeoff. Why do you think it’s “better” for your use case? Is that a theoretical advantage or is that something that is measurable today? Do you think it makes a difference for the laptop form factor?
I can tell you right now I don’t really care about a laptop tech that doesn’t support ECC. I am not gonna buy such a configuration.
It can be much faster (like 50+%) which has quite an impact especially for the igpu and uses less power doing so. Absolute win. Honestly I am not sure that’s worth giving up for the few people that are actually going to use ecc. Would love to get both though so that’s a bummer.
Form a strategical perspective it completely removes the current advantage to soldered ram (at least the customer facing ones, soldered ram is still cheaper for the manufacturer and gets users to upgrade the whole machine).
