New PC Build RAM compatibility?

[Pexy13]

Greetings!

I am curently looking for parts to upgrade my curent PC. 

I am planing a ryzen 5 3600 as a CPU, ID-COOLING SE-224-XT Basic for a cooler,  ASUS PRIME A520M-E  for a motherboard so far. I already have a RX 590 nitro.

I found a DDR4 3866Mhz (2x8GB) Patriot Viper Steel memory on 50% off. But I'm not sure about the speeds.

Could my system even run at full 3866Mhz ram speeds? Would I need to OC something for it to work? Should I just buy the ram because it's a good deal and just let them run at a lower speeds?

If you have any questions feel free to ask, all answers are welcome.

Thanks,

Sven

What is the actual price of the RAM atm?

Also why a 3600 and a A520 board?

Not likely. For best performance, you need to run 1:1 with the FCLK (the infinity fabric clock), which tops out at 1800MHz on Zen 2. That means the maximum speed you should use is 3600MHz (2x1800MHz, since DDR is double data rate). You can sometimes overclock the FCLK, but getting it up to 1933MHz is going to be pretty much impossible. If you can't match the RAM clocks to the FCLK then it will run 2:1 and performance will be worse that having far slower RAM. You could also just run the RAM slower, and maybe use the extra headroom to tighten the timings, but YMMV there, and it's usually not worth the cost of the faster RAM to begin with. Just stick with 3600MHz.

The ram is 88usd atm.

 

What do you mean by 3600 and a A520 board?

Just get a normal 3200 CL16 - 14 kit.

Honestly, don't get a R5 3600. Not worth it in 2021. Get an i5 11400F + a B560 board. Much better value and more performance.

I thought I would buy the Vipers at 88usd and let them run slower and save monney because the cheapest 3600Mhz ram I cand find is 117usd. Would the vipers automaticly run at 3600 or would I need to set it manualy and mess around with that to work best?

I mean the i5 and a b560 would be great but it would cost me aound 85usd more and my budget is pretty tight as it is.
