Crucial winding down doesn't mean that there's less flash fabs in the world, just like there are plenty of DRAM companies that sell to the consumer market that don't have their own flash fabs (Corsair, Gskill, Geil, etc). Those consumer oriented brands bought flash from Micron (not crucial), SK (also doesn't have a consumer facing DRAM brand), and Samsung. That's just as true today as it will be post Feb 2026 when Crucial closes it's doors because Micron selling components to say, Corsair, is an Enterprise transaction from Micron's perspective (B2B), even if the ultimate end product is a consumer oriented one.
Technically you're right, they do. They don't really serve the US Consumer market (anymore) though. There's no (or comparatively very few) established sales channels with consumer retail vendors by SKHynix themselves in the USDM. It's all reseller stuff, often plucked from OEM devices (prebuilts, workstations, etc).
What you linked is OEM RAM. The enterprise market still uses lots of UDIMM's, even though it certainly favors RDIMMs. Yes, it's DDR UDIMM's that are compatible with consumer PC's. But it's not sold like Samsung or Crucial consumer-oriented memory is, at least in the US market. Check the availability of it compared to say Crucial or Samsung. It's virtually non-existant. Check the comments on that very site as well, note how many people are talking about getting them from pre-builts (aka OEM/SI). Note, SK selling UDIMMs to SI/OEM's for consumer products is not a "consumer transaction" to SK, that's a B2B enterprise sale to another company from SK's perspective.
So technically yes, but practically no, not in the US they don't. Elsewhere I'm unsure, but SK has been deprioritizing consumer DRAM sales for a while now, just like Micron.
