Hello again. I would not use LLC unless you are manually overclocking. Leaving your voltage on AUTO and adding LLC will overshoot your voltages, possibly destroying your CPU. From experience, I'd advice you guys who use AMD Ryzen CPU's to simply stick to stock speeds, AUTO voltage, Enable PBO, get either Micron E-Die, or Samsung B-Die memory and tinker with the RAM, not the CPU speeds. AMD Ryzen CPU's are very capable CPU's out of the box, both for gaming and productivity. Like I said, just enable PBO and you're set to go- Let the motherboard take control.
Ram on the other hand is where the performance can be improved and make a huge difference. Micron E-Die and Samsung B-Die are well known IC's for overclocking and will definately boost your gaming performance when tweaking out the timings, and sub-timings. Use the Ryzen Calculator found here at Techpowerup. Download Thaiphoon burner to read your memory specs and get the information the calculator will ask you for. You DO NOT need to upload your memory profile into the calculator as many try to lead you to believe. I have tried this and followed the recommended settings and it in fact makes things unstable.
Just use the calculator without the RAM profile uploaded and set the correct info obtained from Thaiphoon burner to fill in the boxes with the information required and use the Safe setting or Fast setting. I bought a Ballistic Sport 3000Mhz CL15 16GB kit of RAM a while back which comes with E-Die IC's. This kit I am currently running at 3733Mhz CL16-19-16-16-36 TRFC 560 and other sub-timings tightened up. My read score is 52363MB, Write 51363MB, Copy 61035MB, and Latency 65.3. Running FarCry 5 using the included benchmark, my avg FPS went from 110 @1080p ultra settings, to 125FPS just by simply adjusting the memory.
Summing things up, do not overclock your Ryzen 3000 series CPU. Its not worth it unless you get one like mine. My Ryzen 3600 non-X model does 4.5Ghz on all cores, auto voltage, no LLC needed 24-7 stable. This is a golden sample as I call it

Voltages stay around 1.43v under full load. Temps never go above 80c using my Noctua NH-D15. Just tweak your RAM and test every overclocking with PRIME95 Custom run 448 min FFT-4096 max FFT. Uncheck Run in place. Set Memory to Use to 80% of total sytem RAM. Run test for at least 2 hours. If your system passes this hellish run, congratulations. You are one of the few out there that actually has a true stable RAM overclock. Cheers.
