No binning needed. In fact many non-top tier module house kits are "downbinned". Plus sponsored overclockers will take the best cut, top bin sold with RGB and top dollar forced on. Apart from top bin, do the tRFC test and run it in the 480 range, there's a good chance it will crap out. Once you disassemble the heat sink, its non-reversible unlike OEMs.
AGBD single side 16GB era, OEM Black Klevv and OEM SK Hynix Greens are guaranteed 8400-8600MT/s tight without the help of a CKD on Z790 Apex (with no manufacturing defects). IMC was RPL bottleneck.
If your target is 8600 (On Z890 Apex/OCF), non-CKD SK Hynix AGBD Greens 5600B UDIMM, ~330RMB. Put the rest of the money on RAM blocks.

If really need to bin, buy 4 sell 2 on carousell. Even the best 2 will easily touch or surpass the typical module house bin. Users like sugil0ver are sponsored or semi-sponsored, when they promote a gskill or other module house product it will feel like an ad, but when its OEM greens the vibe is gone.
Edit: The renesas PMIC on Klevvs are abit more picky with getting the right voltages at each speed tier. Greens are straightforward. DDR5 has totally changed the rules of buying DIMMs over DDR4.
The OCN posts that can read more are from users like veii, stilt, tibcsi, falkentyne (doesnt really do ram) etc.
Sugil0ver,
centvalny etc can take it as posting on behalf of their respective "OC teams". The most they will post is a dangwang <200% ram test coverage, when dangwang testing needs 20000%+.
