Overclocking Results


On the Intel side of things I do this section, I test maximum CPU frequency, maximum stable frequency, and I go through many different memory kits and see if their XMP works. Well, AMD's Ryzen platform is quite new; AMD and its partners are working very hard on fixing issues and getting things to work across the board. The CPU also doesn't validate that much higher than its maximum stable frequency.


Memory overclocking is topped at 3200MHz on most motherboards, and bus adjustment is also very tricky. Don't get me wrong, the CPU can overclock, mine does 4.0GHz, and the best I can get a kit is to 3000MHz.


I will go through and tell you exactly what I did to achieve my maximum stable overclock, and as AMD's ecosystem of compatible memory kits becomes larger, I will add in a memory compatibility section.





To achieve the overclock you see above, I set all CPU cores (all eight with SMT enabled) to the 40x multiplier. I actually didn't need to set the core voltage, ASUS and AMD's auto rules were good enough to increase the core voltage enough so that I didn't need to set it myself. They also seemed to not overvolt the CPU, as I measured the VCore. I will say that CPUz VCore readings are incorrect, it's best to use a digital multimeter and the voltage read points.


Memory overclocking was done by setting DOCP, a setting in ASUS's UEFI that increases the memory to its "XMP" level, here it applied the 29.33x multiplier and set theDRAM voltage and timings. The motherboard is also one of a few that has an onboard clock generator, allowing bus speed increases.
