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.

CPU: i7-2600K 4751MHz 1.44V (software) --> 1.47V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 103.3MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 2133MHz 10-11-11-30 CR2, custom: 2203MHz 10-11-10-26 CR1 tRFC:230 tREFI:14000) GPU: Asus GTX 1070 Dual (Super Jetstream vbios, +70(2025-2088MHz)/+400(8.8Gbps)) SSD: Samsung 840 Pro 256GB (main boot drive), Transcend SSD370 128GB PSU: Seasonic X-660 80+ Gold Case: Antec P110 Silent, 5 intakes 1 exhaust Monitor: AOC G2460PF 1080p 144Hz (150Hz max w/ DP, 121Hz max w/ HDMI) TN panel Keyboard: Logitech G610 Orion (Cherry MX Blue) with SteelSeries Apex M260 keycaps Mouse: BenQ Zowie FK1

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

Not a pro, not even very good.  I’m just old and have time currently.  Assuming I know a lot about computers can be a mistake.

 

Life is like a bowl of chocolates: there are all these little crinkly paper cups everywhere.

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