A typical 32GB (2×16GB) DDR5 kit seems to cost around €500 here, but I found a new Kingston FURY Beast White RGB kit on Amazon listed for €243. It is rated at 5600MT/s with CL40 timings and supports Intel XMP. The specifications are a little slower than the commonly recommended 6000MT/s CL30 memory for AM5, but that alone does not seem bad enough to explain such a large price difference. The seller is Tekra. Is this simply a good deal, a listing mistake, or something suspicious about the seller or product?

The listing could be a pricing error, but a new kit at that discount is suspicious enough to verify everything: exact model number, seller identity, warranty coverage, and whether the listing is fulfilled by the platform. Used 32GB kits can sometimes be inexpensive without being scams, but a supposedly new product from an unknown seller deserves caution.
For an AM5 build, 6000MT/s with CL30 is usually recommended because it tends to keep the memory controller and fabric operating efficiently. A 5600MT/s CL40 kit will have higher latency, but that does not make it defective or unusable. It is mainly a value and performance trade-off rather than an automatic reason to reject it.
CL40 at 5600MT/s is slower than the popular 6000MT/s CL30 combination, but it is still perfectly usable. In most games, the difference may only be a few percent and can be hard to notice unless the system is particularly memory-sensitive. The unusually low price is more concerning than the specifications, so check who actually sells and ships it and read the seller reviews carefully.
I would investigate the seller before ordering. There have been cases of suspiciously cheap memory listings from third-party sellers, especially when the price is far below comparable products. If it is not sold directly by Amazon or a reputable retailer with strong recent reviews, I would probably avoid it or only buy if the return policy provides solid protection.

An X3D processor can reduce the performance gap between different memory speeds and timings, so the difference may be even less noticeable with one of those chips.
