Just built a new computer using the Phantom Gaming 4 X570 Motherboard, but I can't get my ram to run at 3200Mhz. Instead it is running at 2133Mhz. I am using this set of ram from corsair: CMW32GX4M2C3200C16
Any help is Welcome
Thanks

you will need ryzen dram calc and thyphoon burner. tb helps you to find out what kind of chip is on your ram modules and give you an overview about what timings they can perform. use the information from tb for dram calc, you can also extract and import a memory profile. for the start go with "safe" settings in dcalc and take great care when adjusting voltages. in your case voltage adjustment will not be needed and the ram runs on default 3200c16 @1.35v. did you try loading the xmp profile yet?

As Soulstealer suggested, try enabling XMP in bios first and set to 3200. Also be sure your memory is plugged into the proper slots (should be A2 and B2, but double check the manual.
I like using the Ryzen memory calculator to tighten up timings, but I think if you are still having problems with setting to the advertised memory speeds the calculator may be hiding the problem you are having.
