Enabling your XMP 2.0 profile

Enabling XMP 2.0 performance profiles

At default, your PC will always revert to 'safe' settings. Your memory will be configured at what is called an SPD JEDEC profile, the safe setting that will always boot your PC. For DDR4 on this platform, this is 2400 MHz with a JEDEC timing in the 15 to CL 19 range. This is done so that during, say, a new PC setup, your memory will always run stable and steady. However, if you purchase a Ferrari, that doesn't mean you can't pass 120 KPH right? This is why both AMD and Intel created memory profiles aka XMP (AMD motherboards can use another name) which is short for Xtreme Memory Profile. XMP is an Intel abbreviation, for AMD it's XMP-A / BEMP or whatever it is called in the BIOS, same thing, different name. Some manufacturers do name it XMP on AMD platforms as well. Once we enabled the XMP profile we can see that the memory frequency, voltages, and timings have updated to what the XMP SPD on the memory is configured for. So while 2400 MHz is standard for the processor and chipset combo, the motherboard manufacturers offer way higher memory configurations and performance as long as your DDR4 memory allows it. How do we get XMP profiles enabled? Simple... go into your BIOS:

Above an example as a reference of enabling the XMP profile

 
You simply enable the XMP profile, save the BIOS and reboot. One word of advice though, use a proper brand motherboard. TeamGroup has a QVL list on their website for each type of memory, showing supported vendors and motherboards. 

Overall if you go with MSI, ASUS, ASRock on Z390 / X570, you're good to go up to 3600 MHz. AMD’s DDR4 support is really good these days, and with Ryzen 3000 and this Ryzen 3000 optimized kit it's great. For Ryzen 3000 the memory is set up in a dual-channel configuration. All processors support standard DDR4 memory with clock speeds of 3200MT/s (JEDEC).

 Double Data Rate: 2x 1800 MHz = 3600 MHz

Please make note of this: On Ryzen 3000 as soon as you go higher than DDR4-3733, a 2:1 multiplier will kick in and Infinity Fabric starts working at half the memory clock frequency. The 2:1 multiplier switches on at DDR4-3733 so do keep in mind that it will have an effect on the speed at which the various core complexes within the CPU can communicate with each other. For the best overall system performance, we, therefore, recommend a maximum at DDR4-3600 speed.
