ASUS B450M-K PRIME MAX RAM SPEED ??

[hyrix7Q]

Hello guys i have ASUS B450M-K PRIME ( 2 slots )  and in the website they are saying this : 

2 x DIMM, Max. 64GB, DDR4 4400(O.C)/3466(O.C.)/3200(O.C.)/3000(O.C.)/2933(O.C.)/2800(O.C.)/2666/2400/2133 MHz Un-buffered Memory

and i want to buy a ram with 3000Mhz but why they are writting OC beside the (2933 / 3000 / 3200 ..... ) speed  do i have to overclock the ram to get 3000Mhz ? 

does that means that my mbo only accepts 2666Mhz  ???

Yes, that's a limit by the CPU. Specifically, that of Zen+ CPUs (since B450 chipset came out when Zen+ is AMD's newest CPU)

Not up to that, you can go hgher. It just means the board vendor and CPU brand is not responsible for memory not going beyond 2666.

is overclocking the ram is as dangerous as overclocking a gpu or cpu ? or it just fine ? 

one more thing the ram i wanna buy is 3000Mhz then i thing the mbo is the one that has to be overclocked right ? because the ram is already 3000  ! and the mbo only accepts 3000 with oc ? but as i said the ram already 3000Mhz by default

Ram is pretty durable. 3000MHz or higher has become rather commonplace these days.

Go into BIOS and enable DOCP (XMP on Intel) and done.

Not dangerous at all, neither is GPU overclocking. CPU overclocking can be tricky if you mess with voltages though you don't want to go too high.

it's the safest thing to overclock in fact, it's just that memory speed is not as important as getting a good CPU and GPU in the first place. Also, stress testing memory is time consuming and there are many possible values you can adjust. You can tune less numbers if you have less time, CL(CAS), RCD, RP, RAS, RFC bring the most impact, along with frequency of course.

i think i dont have XMP on my mbo where can i find it ?

When the ram is running at 3000MHz the motherboard is not the one being overclocked. 

 

Without XMP, ram usually runs at 2133, 2400, or 2666 (almost always 2133) by default, so any dimms running at 3000 are above their native speed, but at their "rated " speed

Asus names their version of XMP as "DOCP" on their boards if I recall

It's in the BIOS, Asus has a good outline here:

You're overclocking the memory controller in the CPU, not the board. You can push memory beyond what it's rated for, that's the "overclocking" I'm refering to previously.
