Can anyone explain to me why on AMD’s website, it says that the max RAM speed for 5900X is 3200 Mhz?

Isn’t this just… wrong? Now I’m freaking out because I’ve been running my 5900x at 3600 Mhz and don’t know if I should be doing that. Anyone know why it says that?

3200Mhz is the highest standardized memory speed of DDR4. Everything above that is considered an overclock. As long as it’s done correctly, there’s nothing wrong with running at higher speeds.

Can you summarize “done correctly”?

Sufficient voltages, correct timings. When a kit of RAM advertises a certain speed with XMP/AMP, they have all these things programmed into the sticks themselves. If you enable XMP/AMP on the motherboard, they will automatically sort themselves out.

Within the memory motherboard and module maker’s specifications.

Done correctly is kind of subjective. If your programs run fast and do not crash I wouldn't look deeper than that. At least considering the level of experience you are displaying. Not trying to be demeaning or anything. You've got what sounds like a nice setup, I'd say you're good!

Not only that, but any XMP profile is also an overclock.

Because that's the highest official standard DDR4 speed.

That’s without XMP enabled, if I recall. The board, chipset, and ram can all enable higher frequencies.

You are fine. No issues

3200 is the max officially supported speed ram speed.

if you ever need to warranty claim your CPU, you tell them you put the system together and never once touched the bios other than updating it. but you didn't hear this from me.... (it would run the default JEDEC memory speed 2133 data rate if you never went in and changed it)

3200 is the max speed guaranteed to work. Anything past that is considered overclocking and while not guaranteed -- it should work if the ram is rated for it.

Can it damage the CPU though?

If you just turned on the XMP profile for your ram it's safe.

If you're motherboard decides to run insane SOC voltages it might. You can check with HWinfo64. Anything below 1.2v is fine.

3200 is the rated speed. 3600 is easily achieved on most CPUs.
