Have I hit a wall with my B-die? 3200mhz cl14 @ 3933 cl14?

[equlizer36]

Im running the Gskill FlairX 3200mhz cl14-14-14-34 kit @ 3933 cl-14-14-14-30 1.6v with tight timings. Passes 3dmark timespy cpu and dram calcs' memtest. Should i lower the timings a bit and try for 4000mhz? Im running a 5800x on a MSI B550-a with 1601 bios. Memory temps at 3933mhz was around 38c. Can post pics of whatever you need if needed

Couple of things I'd recommend with tweaking/overclocking RAM and Ryzen is that you are actually seeing a performance increase in game benchmarks, etc. and, depending how sensitive you are to it, that it isn't impacting on the smoothness of games - Ryzen tends to have a sweet spot that provides the best overall results and more isn't necessarily better. (This is somewhat but not entirely related to things like infinity fabric ratios, etc.).

Nice RAM overclock. I would stay to =<1.5 volts maximum with b-die. Some people will go higher. With Ryzen cpu's the optimal RAM MT/s is twice the IF frequency. So say the IF is 1900 MHz then the RAM can run optimally at 3800MT/s. If you download aida64 you can use the memory test to see the latency of your RAM. With my RAM I am about 48.6ns for DR @ 3600 CL14. With AMD the latency on Ryzen 3000 series would drop towards 60ns from 70ns approx. as memory timings improved.

I would get a USB stick and buy a full version of memtest. You are going to need it if you want to really overclock your ram. Also you are going to have to run a stress test to make sure your IF is stable as well. Prime 95 or aida 64 are good choices. I like 10 hours smal fft's and 10 the hours large ffts. Other people use their own methods. I have even just left prime 95 running for 10 hours. Aida 64 work well too. You have to do this as I have found that RAM can be stable but you can get restarts. Likely due to the IF. Also you need to research the safe voltages for Ryzen 5000 series cpu's. Important you stay in the safe voltage ranges for your cpu. DRAM Calculator for Ryzen can help but knowing what you are doing is even better. MEMbench can show you how well your memory is performing compared to other Ryzen systems.

Final testing of the RAM should be done outside of windows. Boot from a CD or USB stick.
For memtest you need to do 8 full passes all at once and 32 passes of test 7. This is the bare minimum and can take 8 hours (depends on memory speed). This covers all the patterns that memtest test with. You can pass 8 full passes and fail 21 passes into the 32 for test 7. This means you have to change timings and retest which is why memory testing is a pain.
