i have 5600g . and i have tested its fclk 2400 with igpu . i oc sticks 5000 freq and it worked well. but i cant overclock my sticks to 5100 and more . i cant boot my pc .
brand: Acer Predator bdie 8gx2
motherboard:msi b550 unify-x

Most B-die won't make 5000+ on AMD. They run a bit higher on Intel chipsets. If you want it to run at 5100-5200, then you need more relaxed timings, so try something like 20-22-22, 20-24-24, or 22-24-24. It will also need high voltages. At this point, it will lose stability because of too high frequency or too high temperature.
For 5000+ RAM clock on 4000/5000 APUs, the best is high binned Micron B or Hynix D as both of them are overclocking higher and require lower voltages. Samsung is great for 1:1 at lower frequencies like 4400-4600 and also runs at tighter timings like CL14-16. If you get good Micron B, then you can set 5600 CL18. Hynix typically runs at 5400 CL20. Great would also be dual-rank Hynix A at 4600 1:1.

I can't help you much as I assume that when you set 5000 stable, then you have enough knowledge to set 5100+. The only problem is the used RAM and/or motherboard. Keep in mind that barely anyone is even trying to stabilize DDR4 at more than 4600, not to mention 5000+. I would work on sub-timings at 4533-4600 1:1 or 4933-5000 1:2. I bet you can get more from that than the next 100MHz at more relaxed timings.

i have tryed 20-22-22, 20-24-24, 22-24-24 and more relaxed timings ,even over 1.65 voltage(1.68 is my max) . and stiil cant boot my pc . today i find a simple way to run at 5100 . i removed one stick , set fclk at 1900, and booted it and it worked well .
i found my 5600g cant work at 2400 fclk when integrated graphics is available . i dont know whether the problem is about integrated graphics . but i heard some people say their 5000 apu can work at more than 2500 fclk when they disabled integrated graphics , but i dont have discret graphics card to confirm it . maybe its all about cpu . my cpu's io die cant burden to push memory run at 5100 . i will get a discret graphics card and try to prove this guess.

1 stick always works higher than 2. The point is to make it work in dual-channel ;) One of the memory slots is always stronger.
IGP usually limits max memory OC. It's because it uses RAM as video memory, and errors appear much faster. Sometimes you get artifacts while booting when the RAM clock is too high ... or it won't boot at all.
2500 fclk would mean 5000 1:1. I haven't seen any APU that could run at more than 2300-2400MHz 1:1. Maybe someone has that one per million sample. There are guys on the OCF who run 5600X/5800X/5900X at 4000 1:1 stable, but I passed maybe 15 CPUs, and I couldn't make them even boot at more than 3866 1:1.
I had problems with Samsung IC at more than 4933 on AMD. On some motherboards, it was booting at 5000-5200, but on most, 4800-5000 was the limit for stability. This is why I was using mainly Microns for 4000/5000 APUs. The same CPUs could run stable at 5400-5600 with Micron B and a bit lower with Hynix D.
One tip, the latest BIOS is not always the best. Try to play with some betas as they typically are tuned for better OC on specific memory IC.
