No info about what we want to know: Timings and type of IC ?
Love from Norway 🙂

The picture used for ram singled out for Ryzen is that of Intel hardware. Just nitpicking.

i wonder if there's a typo, 4866 instead of 3866

I'd personally wait for ddr5, than spend 1k on ddr4 cl18 ram.

Considering most 3rd gen Ryzen users like myself can't even get the CPU fabric clock to run at the AMD recommended maximum 1:1 ratio of 1800MHz (for a memory DDR clock of 3600MHz)... I don't know what use 4866MHz RAM is - apart from the usual of manufacturers being able to sell the same thing for more money.
I bought high-end 4000MHz RAM to have some headroom to make sure it would run at the recommended 3600MHz... I can't even get it to do that... can only get it stable at 3400MHz maximum (and that's using AMD DRAM Calculator and high-end RAM using Samsung B-Die modules).

Voltage is still sensitive as was with first gen Ryzen. The recommended minimum was too high until this current version 1.6.2. Also the Memaddr/MemCsOdt/Memcke settings, they were off with earlier versions. 0 still does not work. 1 does work but 60 (the alternate recommendation) works better. Only thing off was the CLDO VDDP. The recommended setting of 700 is too low; refuses to boot. 800 was the perfect setting. So as recommended for 3800, cadbus is at 24-20-20-24. ProcODT @ 34.3 and 1T. Those settings allowed me to even tighten TwtrS -TwtrL-Twr to 3-10-10. PE is set to "default" and PBO to enabled. CPU is offset -.03125 and Soc offset +.00625. Fabric is stable at 1900. If Soc is increased or decreased literally one step, game over; same with the Ram voltage @ 1.39. Just need to find the right combination. Agesa version is 1003ABB.
