According to NEMO this Intel certification is irrelevant and doesn't mean this kit is optimised for Intel at all, only that it has been certified to work with Intel XMP. When I pointed out that this product is listed as certified to work with EXPO, yet the packaging and sped sheet seems to state otherwise, Nemo basically politely suggested I didn't know what I was talking about.
Well, how much work memory manufacturers actually do to optimise their kits is a point of contention (and it might well be nothing, or a lot..), but the fact is an XMP kit has XMP profiles and an EXPO kit has EXPO profiles.
I note the comments on the immaturity of AM5 sockets and X3D CPUs and I am also considering that, but in a case like this you want to work to rule out possible or probably causes, and with evidence online that XMP optimised RAM can cause issues in AM5 builds I would like to get the RAM changed out for something that definitely does run properly. Overclockers refuse to accept there is any issue or do anything about this so my options are to purchase alternative RAM separately, or try escalate it further independently. Im currently collecting more information, which may include having to go through every motherboard product on the market because if I cant find any that will run EXPO profiles with the RAM then the claims of EXPO certification must be false.
The only advice I can give about the likelihood of the RAM causing a problem is that your RAM is listed on the QVL as supported. Manufacturers are effectively having to support two different memory profiles and if they're forgetting about XMP and optimising for EXPO, I'm not sure, but I do know that XMP does work and has worked since launch.
Ive yet to run a RAM test so Ill do that this evening. If there is a fault at least I could return it under warranty, but Im pretty certain that OCUK will force a like-for-like replacement.
I might be mistaken, but I believe you can ask for a refund on a faulty product within 30 days.
Since something appears to not be running properly at stock either, I'd definitely be doing a RAM test. I'd also check other potential config issues like PBO and the usual troubleshooting with BSODs (updating to the latest drivers, etc). I'd also check the most basic thing, which is that when you enable DOCP the memory voltage is also being changed (and I'd do this even at stock).
I have yet to see a single product that carries both Intel and AMD certifications on the packaging. This is something I took up with OCUK but to be frank, they couldn't give a monkeys and have told me there is nothing they can do, which isn't true, they could if they wanted to bu they just don't want to. I used to work in e-commerce retail so I am fully aware of how this sort of thing works and how relationships with suppliers and manufacturers is. If Kingston wont do anything its not a brand I want to use either, but as far as I can tell OCUK haven't even contacted them. I think OCUK are just hoping I will go away to be honest, which I fins unsatisfactory.
I believe this is an example of an XMP and EXPO kit: KF552C36BBEA-16. It is listed on the Kingston store as having two profiles of each. I couldn't find any kits that were not advertised as XMP or EXPO though, this one is listed under EXPO and here's the description:
"Includes JEDEC default, two EXPO 1.0 profiles, two XMP 3.0 profiles and one user programmable profile"
The datasheet also confirms this.
I guess it is possible that your kit has been updated and the datasheet is old news, but since EXPO profiles don't show up in the BIOS, I don't think that's the case. You can also get the SPD data with CPU-Z (SPD tab), or HWINFO.
Ive seen some 24 Gb modules appear now, Im thinking of changing out to those as I only really need 32 Gb for gaming and the only reason I went with 64 was for the peace of mind afforded by having lots of headroom. 48Gb would still be plenty of headroom anyway. Im looking at my options.
My honest opinion is that 24/48GB is even more likely to be problematic than XMP, because it is likely XMP has been more thoroughly tested, with a wider range of modules.
The QVL does specify whether XMP, or EXPO is or is not on the certification though. In this case, those motherboard clearly does not certify this RAM part for EXPO. In doing a couple quick searches the next 2 motherboard I looked at didn't support it either. My next step will be to get a full list of all the motherboards available on the market and check each and every one of them to see how many will actually run EXPO and how many wont. IMO, at least half need to run it if Kingston want to claim this as an EXPO-certified product.
Like you, I can't find any evidence that Kingston have ever made this claim and I don't know what store they're saying the copy-paste is from because Kingston's store lists this product as XMP:
Upgrade your gaming setup with Kingston FURY™ Beast DDR5 RGB XMP memory. Experience stunning dynamic RGB lighting effects that elevate your gaming aesthetics. With speeds ranging from 4800MT/s to 6000MT/s and capacities up to 64GB, unleash the power of DDR5 technology. Benefit from on-die ECC...

My guess is that what they copied is generic marketing guff about Kingston Fury, not any specific kit.
Im still waiting for a reply form OCUK on this, but if they begin to just ignore my emails, as a suspect might happen, I guess I will need to go to the manufacturer themselves to get their view on it.
I don't think you'll find any board which lists this part number as EXPO, because even if the kit has been updated to support both (which I'm not convinced, though I guess Kingston would be in a better place to know), the QVL is usually produced on release and rarely updated unless something major changes (like a new generation of CPUs, or a new revision of the board).
