I wonder how you managed to reach 3800 C14 with that setup. You mentioned 1.6v, increased the SOC voltage and clock to 1900MHz.
I'm in agreement, though it's a bit amusing. I ran it on my 5800x3D and the 3600mhz sounds much more responsive than the 3200. It might just be a placebo effect, but I'm also seeing slightly better benchmark numbers. So while I can't confirm a higher FPS, it definitely feels snappier. Despite not doing much, I kept my RAM OC at its default setting—just because things felt smoother. Also, I set the SOC to 1.15 by default; I'm not really an expert on RAM OC settings, so I bought a BIOS that seems super simple to adjust. The voltage is still around 1.36V.
From someone who built that system before, it shouldn't be too tough with a decent motherboard and CPU. On my end, I only needed to adjust the SoC voltage to 1.15V, set the vDIMM to 1.5V (my DIMMs were in a high-density die range so they didn't require much voltage for tight timing), and configured the frequency at 3800MT/s with an FCLK of 1900MHz. The rest just fell into place—timings were fine-tuned to 14-13-13-21 using custom settings, and I ran some stress tests afterward.
