Hello All,
Dark Hero on order. Need to buy ram. I'm trying to find the optimal choice. However, I've watched both Gamer Nexus & Hardware Unboxed videos on best ram for Ryzen 5000 and tbh I'm still unsure.
I would like to have 32GB of ram. I dont believe I will ever need more because Ive been on 16gb for years and only occasionally get close to full usage.

Heres what I understand so far:
The Dark Hero is daisy chain so I believe 2x16gb (dual rank sticks) are going to clock faster than 4x8gb (single rank sticks but when configured like this they all run at dual rank). This is due to having the benefit of only using 2 slots. Using 4 slots has the penalty of slowing down the ram due to extra latency from the added/unequal ram traces to the cpu. So even though 4x8gb is dual rank it will run at slower stable speeds than 2x16gb. Is this actually true?
I saw in the Hardware Unboxed video the higher performers were actually single rank tuned 2x8gb sticks. Practically equal to 4x8gb dual rank however. So, assuming 2x16gb clocks higher than 4x4gb, is the fastest config 2x16gb tuned?

If so what ram should I grab?
2x16gb 3600 cl16 overclocked to 3800 cl16 (probably cheaper)
2x16gb 3800 cl16
2x16gb 4000 cl16 (not sure if Dark Hero can handle 2000 1:1 mem fabric)

Links to suggested ram are appreciated.
Thank you for any advice.

16gb sticks will always be dual rank, they are still a better option than 4 x single rank 8gb sticks.

As you said 4 sticks puts more stress on the memory controller and increases latency.

Buying would depend on price differences, 400mhz CL 16 would be first choice but if its inordinately more expensive then probably not so much.

Looking around 4000 cas 16 is twice as expensive as 3600, the performance difference is absolutely not worth that amount of money imo.

Case in point, the perfoemance difference is kind of minimal.

3600 cas 16 is 'fast enough'

This guide is missing the same info as Hardware Unboxed video on ram. The tuned dual-rank numbers.
They only show dual rank at stock speeds and the 4x8gb is only at 3200. They also show single-rank tuned as best performer.
Why in the charts are there no tuned dual rank numbers? Is it not possible to have 4x8gb 3800 or 2x16 3800?
