So I'm looking at this ASrock B450M Pro4 F MoBo, in the specifications it lists a variety of memory speeds, ending on 3200+(oc). What does this mean exactly? I know oc means overclock, but I was thinking of getting 16gb 3600mhz ram, will it work at the rated speed on this motherboard or what? Thanks in advance.

Ram speeds are dependent on the cpu, not the motherboard. That B450, just like any other B450 is intended for 2nd release Ryzen cpus, the 2000 series. Those cpus are limited in ability to the speeds listed, at the time of that bios release.

They don't add 3rd release info to the motherboard listing as that would not be correct advertising, if you bought 4000MHz ram and stuck in a 2700x, you won't get that speed.

3200MHz (OC) means 2 things. You will have to overclock the ram (manually or xmp/docp) to get that speed and there exists the potential you may also have to overclock the cpu in order to get stable at that speed. Many Intel motherboards with a B/H rating, do not support the faster than default cpu setting because the bios...
All DDR4 RAM have a default speed when not overclocked. Some of them are 2133MHz. Some are 2400MHz. The moment you use the XMP/DOCP profile in the BIOS to run the RAM at the advertising speed it's overclocking the RAM so that's why it says (OC).

What is the CPU you have? Not only the board and ram are a deciding factor in the RAM decision. The CPU memory controller is important too.

thanks for the quick reply! I was thinking of the ryzen 3200g (tight budget)

This is a Zen+ CPU. RAM should be fine at around 3200. If it's not stable at 3200 you just run them at 2933MHz.

This is CPU with integrated graphics. That's what you want? Do you have a graphics card?
No gpu, no. That would be the next upgrade down the line, this would just be a build to get the pc going , then it can be upgraded bit by bit later on:)

Ohh right, that makes sense. Thank you!
