Ryzen 5000 series RAM compatability

So I'm planning on buying a 5800x and the amd website says it supports up to 3200Mhz ram. Does that mean It wont work with 4000Mhz ram and I should just buy some 3200Mhz ram?

It just means memory are not guaranteed to run faster than 3200MHz. In other words, dont bother asking them why your memory wont work above 3200MHz.

No data yet other than rumors. It’s not out yet.  That AMD would reduce the memory clock speed of their new chip is highly unlikely.  There is one rumor that states ryzen3 will have a 4000mhz max for 1/1 instead of a 3733 max of Ryzen2 because of changes to the infinity fabric.  Rumors are very often totally worthless though.  Ryzen2 supported ram vastly in excess of 3733, but it caused the infinity fabric clock to do obnoxious things.  It’s possible 3200 is a minimum speed.  Default speed of ryzen2 memory was 2133

It's likely the Infinity Fabric will tolerate increased speeds. Every Gen so far.....
