2x32GB DR Samsung DDR5 overclocking results for CMT64GX5M2B5600C40 on a Ryzen 7950x (with benchmarks at each step, tREFI scaling, graphs, temperatures, tips and a small review)

Wow respect for such a comprehensive OC test!

I've spent a couple of days getting my 2x16 GB Kingston 5600 CL40 XMP (should be M-die) to a seemingly stable (Karhu at 3600% and 5 runs of PY 2.5B reaching 99-100°C, still need to run TM5) 6000 CL30 and there's still some reserve left but doesn't want do to CL28 or some tight timings that other people are able to run. TRFc 525 errored out at 1800% and 10. cycle of TM5, so now i'm at 585, Trefi at 11677.

Haven't managed to get 6200 to work, or anything under CL32 at 1.35v doesn't work, need to run 1.4v. Temps while gaming are 54°C, after 1.5h of TM5 they sit at around 65°C. Maybe i should move the bottom two fans closer together as not RAM sits right in the space between the fans haha.
