DDR4 vs DDR5, Explained
DDR5 doubled the bandwidth and moved power regulation onto the module. Whether that is worth paying for depends entirely on which platform you are building.

PHS-memory DDR5-5600 ECC UDIMM 1x32GB 4800 CL40 price history in FR: current low €840.28, 12-month low €238.33, 12-month median €829.70.
Fair price — current price is 1% above the 3-month median.
PHS-memory's ECC UDIMM line is built around error-correcting DDR5, which puts it in a different category from the gaming and mainstream kits most of this site lists — ECC trades a little overhead for the ability to detect and correct single-bit memory errors, more relevant to workstations than a gaming rig.
The family covers two speed grades and a wide capacity spread, running as 1×32GB up to 32GB depending on the listing you pick. Because this is ECC, it will only function as ECC on a board and CPU combination that actually supports error correction; a standard consumer gaming board won't report it as ECC even if the module physically fits the UDIMM slot.
Confirm your platform's ECC support before ordering, since the slot itself won't stop you from buying the wrong part for a non-ECC board.

Flare X5 is a heatspreader-only DDR5-6000 line built for clearance-constrained builds, and within this 6000 MT/s grade every listing shares that one headline speed — the CL bin and capacity are the only things actually separating listings.
FURY Beast at 6000 spans three CL grades under one name plus a four-module 64GB option its 5600 sibling doesn't offer, which makes matching the exact SKU more important here than with most families.
Crucial Pro trades looks for a compatibility-first, overclocking-headroom pitch, and within this 6400 MT/s grade, CAS latency -- not the shared headline speed -- is the number that actually separates one listing from another.
16 GB is no longer comfortable, 32 GB is the sensible default, and 64 GB is a workload decision rather than a future-proofing one.
Capacity avoids stutter caused by running out of memory; speed affects how efficiently the CPU feeds data to the GPU. They solve different problems, and buying enough of the first one before spending on the second is the right order.
